The effects of carbon disulphide are known on lipids and carbohydrate metabolism, on thyroid functioning (triggering hypothyroidism) and on coagulation metabolism (promoting thrombocyte aggregation, inhibiting plasminogen and plasmin activity). Construction workers have a hard time because they need to be careful at all times otherwise they may end up injured. It can be assumed that such results will not ensue with a healthy coronary vessel system and intact myocardium (Fritze and Müller 1995). The relative risks for high blood pressure range between 1 and 3.1 in com- parisons of exposure to loud and less loud noise. It may also cause problems with the eye and the cornea will be burnt which will lead to cataracts, which is most commonly seen on the elderly. A hazard is anything with the potential to cause bodily injury, and includes any physical, chemical, biological, mechanical, electrical, or ergonomic hazard. These drugs may cause brain problems and even cause you to have a gap in your skull/brain or may cause the child to be addicted without trying the drug. It is paradoxical that the result of reducing heavy dynamic muscle work—until now greeted as a significant improvement in the level of strain in the modern workplace—possibly results in a new, significant health problem in modern industrial society. Carcinogen, any of a number of agents that can cause cancer in humans. Still being discussed is whether a direct cardiac effect exists such as reduced contractility, suppression of impulse formation centres, impulse transmission, or reflex impairment resulting from irrigation in the upper airway region. The possibility of cardiovascular effects from ultrasound (frequency range between 16 kHz and 1 GHz) and infrasound (frequency range >>20 kHz) are discussed in the literature, but the empirical evidence is very slight (Kristensen 1994). Kristensen (1989) concludes that the hypothesis of an acute risk increase for complications from cardiovascular disease in people with underlying organic disease is confirmed, whereas the hypothesis of a chronic effect of heat or cold can neither be confirmed nor rejected. 1987). Exposure to loud noise almost always results fairly quickly in changes such as in blood cortisone, cyclical adenosinmonophosphate (CAMP), cholesterol and certain lipoprotein fractions, glucose, protein fractions, hormones (e.g., ACTH, prolactin), adrenalin and noradrenalin. This can affect virtually all occupational groups after a workplace accident. Most cold-related deaths occurred in people with cardiovascular diseases, and most heat-related deaths were associated with respiratory tract illnesses. Category 2 carcinogens are suspected human carcinogens. Don’t take any drugs as they will affect your health and you may become addicted to them. The consistency of the connection in various countries and population groups, over time and in different age groups, is furthermore convincing. Following evaluation by the Secretary of the Carcinogenic and Mutagenic Substances Committee, a recommendation will be made to the Chairman of the Carcinogenic and Mutagenic Substances Committee for approval for the use of the chemical… (1995) assessed the mortality rates between 1977 and 1987 in a cohort study of French potash miners. 1991), Workers in meatpacking, fish

If exposed too long than this will happen, so it is best not to have a lot in a period of time. Metabolism of Chemical Carcinogens. Lead attacks the contractile mechanism of the vasa muscle cells and causes vascular spasms, which are considered causes for a series of symptoms of lead intoxication. Poss- ible cardiovascular risk is not being discussed at present (Gamber- ale 1990; Knave 1994). Some authors have concluded that a causal relationship possibly exists between temperature stress and the pathogenesis of cardiovascular diseases (Curwen and Devis 1988; Curwen 1991; Douglas, Allan and Rawles 1991; Khaw 1995; Kunst, Looman and Mackenbach 1993; Rogot and Padgett 1976; Wyndham and Fellingham 1978). 36. The thing with UV is that it mainly damages the skin and the cells inside. Epidemiological data and pathogenetic investigations to date have produced no clear results on the cardiovascular toxicity of other metals like cadmium, cobalt and arsenic. The participation of the heart can appear either during or after the actual infection. The experimental knowledge on hormonal stress effects and changes in peripheral vasoconstriction, on the one hand, and the observation, on the other, that a high workplace noise level >85 dBA) promotes the development of hypertension, allow us to include noise as an non-specific stress stimulus in a multi-factored risk model for cardiovascular diseases, warranting high biological plausibility. This study looked at non-smoking women aged 35 ±8 years, so according to v. Eiff’s results (1993), the noise-related risk of hypertension among men could be significantly higher. The results are contradic- tory. Regular, leisure-time physical activity appears to reduce the risk of coronary heart disease through various physiological and metabolic mechanisms. In the 1980s and 1990s the possible effects of electrical and magnetic fields on human health have attracted increasing atten- tion from people in occupational and environmental medicine. Carcinogens that act as mutagens may be biological, physical, or chemical in nature, although the term is most often used in relation to chemical substances. You can order Unique paper and our professionals Rewrite it for you. 1990; van Dijk, Veerbeck and de Vries 1987), no connection was found between noise exposure and high blood pressure, whereas hearing loss and high blood pressure have a positive correlation after correction for the usual risk factors, especially age and body weight. 2020 © gradesfixer.com. These agents may be biological (specific viruses or bacteria), physical (ultraviolet light, x-rays) or chemical. In the studies, of 1,228 and 1,194 people with acute myocardial infarction respectively, the physical strain one hour before the infarction was compared with the situation 25 hours before. The use of modern vast data bases of chemical carcinogenic and mutagenic characteristics as well as of their physicochemical parameters allows to apply the contemporary methods of statistical analysis to the problem of the phisico-biological correlations. If allowed to accumulate in the human body in large amounts or for extended periods of time, there is a higher likelihood that your cells will become damaged, resulting in the growth of cancer cells. Where monotonous improper strains cannot be avoided, counterbalancing with free-time sports activities of comparable duration should be encouraged (e.g., swimming, bicycling, walking and tennis). The problem with this type of investigation clearly lies in the difficulty in measuring and assessing “hard work” and in excluding preselections (healthy worker effect). This hypothesis was supported by Khaw in the following observations: Exposure to cold increases blood pressure, blood viscosity and heart rate (Kunst, Looman and Mackenbach 1993; Tanaka, Konno and Hashimoto 1989; Kawahara et al. Table 1 gives an overview of possible occupation-related infectious diseases that affect the cardiovascular system. This may be due to the ability to damage the genome or to disrupt cellular metabolism or both rendering the cell to be sensitive for cancer development. If you inhale irritants or toxic chemicals, it may cause the worker to have irritation to the airways, headaches or dizziness. These studies involve questions of the significance of physical strain or a stress-induced increased output of catecholamines on the coronary blood supply, on triggering coronary spasms, or an immediately harmful effect of catecholamines on the beta adrenergic receptors of the heart muscle membrane as a cause of the infarction manifestation or acute cardiac death. 1988). To protect yourself from heat, wear special fire and heat resistant clothes that contain a special material called Nomex and make sure to fully protect yourself so there is full protection. 1966), and the study of Paffenbarger et al. Types of mutagens Physical mutagen Chemical mutagen Biological mutagen 6. If you’d like this or any other sample, we’ll happily email it to you. Certain immediate effects of low-frequency magnetic fields on the organism that have been scientifically documented through in vitro and in vivo examinations of low to high field strengths should be mentioned in this connection (UNEP/WHO/IRPA 1984; UNEP/WHO/IRPA 1987). The noise level factor nevertheless constituted half the risk of hypertension of the first two named factors. Visual (induced with magnetophosphene) and nervous effects are reported at 10 to 100 mA/m2. This increased risk is comparable to that found for hypercholesterolemia, hypertension and smoking (Berlin and Colditz 1990; Centers for Disease Control and Prevention 1993; Kristensen 1994; Powell et al. The Safety, Health and Welfare At Work (Chemical Agents) Regulations, 2001 and the Safety, Health and Welfare at Work (Chemical Agents) (Amendment) Regulations 2015 apply to any enterprise where hazardous chemical agents are used or generated. It is assumed that endogenous factors (e.g., in the sense of a primary Raynaud’s phenomenon) as well as exogenous exposures can be held responsible for the occurrence of a vibration-related vasospastic syndrome (VVS). It should be mentioned that cold stress is not only a function of temperature. A few examples may be from heat, objects that fall, construction work, etc. Ionizing Radiation, Electromagnetic Fields, Radioand Microwaves, Ultra- and Infrasound. An example is pesticides for bugs which may cause lymphoma or leukemia of exposed for a very long time. By chemical_report. Differences among the blood pressure group means are relatively narrow, with values between 0 and 10 mm Hg. They are the tobacco smoke, pathogens, radiation, environmental hazard, and the diet.

Even with combined physical-mental strain or physical strain under the effects of noise, a substantial increase in blood pressure and heart rate are seen in a certain percentage (approximately 30%) of people (Frauendorf, Kobryn and Gelbrich 1992; Frauendorf et al. The temperature at which the lowest cardiovascular mortality was observed is higher in Taiwan than in countries with colder climates. If whole-body mechanical vibrations have an effect on the cardio- vascular system, then a series of parameters such as heart rate, blood pressure, cardiac output, electrocardiogram, plethysmo- gram and certain metabolic parameters must show corresponding reactions. Lasting high blood pressure from chronic lead intoxication can be explained by vasospasms as well as kidney changes. The authors judged that no confounding was present due to overweight. Studies that examine the various effects of radio and microwaves have found no detrimental effects to health. AVAILABLE SOON! 1986; Lloyd 1991; Neild et al. Thomas C. King MD, PhD, in Elsevier's Integrated Pathology, 2007. It is not yet clear how these results should be interpreted. When the vasa-widening effect of the nitrate is removed, an autoregulative increase in resistance occurs in the vasa, including the coronary arteriae, which produces the above-mentioned results. This listing makes clear that problems of inclusion, combined exposures, varying consideration of compounding factors, changing target sizes and assessment strategies play a considerable role in the findings, so that uncertainties remain in the conclusions of these epidemiological studies. “A biological hazardous material can be defined as a biological material capable of self-replication that can cause harmful effects in other organisms, especially humans” (American Industrial Hygiene Association 1986). A selection of relevant activities and industrial branches can be found in Table 1. Essay. You would need to wear boots with a metal toe cap and a hard hat, different workers have different hard hats, even visitors get a different coloured hat, make sure their whole body is well insulated with the correct clothing, wear gloves at all times, goggles, and for those who are working high up in the sky, they would need to make sure they are wearing their safety harness. Increases in heart rate are apparent only under very heavy vibration loads; the influence on blood pressure values shows no systematic results and electrocardiographic (ECG) changes are not significantly differentiable. Only a minor fraction of chemicals cause cancer. Thus the electrical voltage that is created in a strong static magnetic field over the aorta near the heart during coronary activity can amount to 30 mV at a flow thickness of 2 Tesla (T), and induction values over 0.1 T were detected in the ECG. It may also cause mental problems and retardation. Increased catecholamine levels can be found in the urine. Pages 241-333. Despite numerous studies, the role of chemical factors in causing cardiovascular diseases is still disputed, but probably is small. It may also lead straight to low weight when born and health problems in the child’s future. Carbon monoxide (Weir and Fabiano 1982) undoubtedly has acute effects, especially in provoking angina pectoris in pre-existing ischaemia, but probably does not increase the risk of the underlying arteriosclerosis, as was long suspected. 1995). Peripheral circulatory disorders resulting from vasoconstriction have been less researched and appear weaker and of shorter duration than those from hand-arm vibrations, which are marked by an effect on the grasping strength of the fingers (Dupuis and Zerlett 1986). ... reasonable to postulate that permanent changes in the DNA or the RNA of a cell can be brought about by chemicals and by physical energy as well as by viruses, ... much less whether this is a general explanation for the role of chemical carcinogens. 1992), but study results are contradictory (Altura 1993; Schwarze and Thompson 1993). In the investigated deaths, often no coronary sclerotic changes were documented. Wikström, Kjellberg and Landström (1994), in a comprehensive overview, cited eight epidemiological studies from 1976 to 1984 that examined the connection between whole-body vibrations and cardiovascular diseases and disorders. Home — Essay Samples — Business — Safety — Biological, chemical and physical hazards. But newer studies have found no difference in the frequency of coronary disease between active and inactive occupational groups or have even found a higher prevalence and incidence of cardiovascular risk factors and cardiovascular diseases among heavy labourers (Ilmarinen 1989; Kannel et al. 1988). The so-called withdrawal syndrome appears when exposure is interrupted for employees with long-term exposure to organic nitrate, with a latency period of 36 to 72 hours. Numerous experimental studies on animals and human subjects permit extending the hypothesis on the pathomechanism of noise to the development of cardiovascular diseases. Consequently, it was assumed that human exposure to exogenous chemicals may lead to toxic and carcinogenic hazards ( 9 ) and that chemical carcinogenesis comprises the three sequential and successive steps: initiation, promotion and progression ( 10–12 ). Another mutagen is from going to too many X-rays as this will cause your cells to mutate and cause cancer. Data sources: Peer-reviewed publications indexed in major databases between 1991 and 2014. Among people who were separated from the company for health reasons, the ischemic heart disease mortality was five times higher in the exposed group as compared to the above-ground workers. Some chemicals can be cleaning agents, disinfectants, compressed gases and drugs. GradesFixer. 1993), the question was pursued as to whether heavy physical work can be a trigger for an acute myocardial infarction. This essay has been submitted by a student. This may be from where you work or where you travel to. An increase in the noise level from 70 to 100 dBA raised the risk for high blood pressure by a factor of 2.5. Two recent cross-section studies focused on metalworkers in Brazil (Kloetzel et al. Chemical Carcinogens Biological Carcinogens Dr.CSBR.Prasad, M.D., 10. No certain effect appears with electrical fields or induced currents under 1 mA/m2. In any case, hearing loss is not a suitable biological indicator for noise ex- posure (Kristensen 1989; van Dijk 1990). on coronary risk among London bus drivers and conductors (Morris, Heady and Raffle 1956; Morris et al. There are no known epidemiological studies of workers exposed to cold (e.g., cooler, slaughterhouse or fishery workers). Still unclear is the decisive question of whether long-term exposure to cold or heat results in lasting increased risk of cardiovascular disease, or whether exposure to heat or cold increases the risk for an acute manifestation of cardiovascular diseases (e.g., a heart attack, a stroke) in connection with the actual exposure (the “triggering effect”). 1979). 1986; Kristensen 1994; Suurnäkki et al. The risk is that injuries or bleeding can result from migration or pivotal motions, and that functional capacities (e.g., of heart valves, pacemakers and so on) can be affected. Pan, Li and Tsai (1995) found an impressive U-shaped relationship between outside temperature and mortality rates for coronary heart disease and strokes in Taiwan, a subtropical country, with a similarly falling gradient between +10°C and +29°C and a sharp increase thereafter at over +32°C. In such situations clear pathogenetic conceptions and knowledge can support the suspected connections and thereby contribute to deriving and substantiating the consequences, including preventive measures. From the occupational medicine perspective, one might conclude that static physical strain on the muscle-skeleton system with lack of movement, presents a much greater health risk than previously assumed, according to the results of studies to date. 1993), Animal husbandry workers,

An … One last thing is if you are exposed to a large amount of radiation. (1993) in a cohort study of French steel workers. HHS is caused by long-term mechanical effects in the form of external pressure or blows, or by sudden strain in the form of mechanical partial body vibrations (often combined with persistent pressure and the effects of impacts). Assessing the physical load, often solely on the basis of job descriptions, must be seen as an inadequate method. In addition to type and virulence of the pathogen, the efficiency of the immune system plays a role in how the heart reacts to an infection. Short chain non-substituted hydrocarbons have a higher toxicity than ones with longer chains. Epidemiological studies, however, point to the positive, protective effects of physical activity on reducing various chronic diseases, including coronary heart disease, high blood pressure, non insulin dependent diabetes mellitus, osteoporosis and colon cancer, as well as anxiety and depression. The triggering mechanism of occasionally life-threatening arrhythmia from these materials presumably comes from myocardial sensitivity to epinephrine, which works as a natural carrier for the autonomic nervous system. According to Woodhouse, Khaw and Plummer (1993a), there is a strong inverse correlation between blood pressure and temperature. Many radioactive substances are carcinogens, but their cancer activity 1986; Kornhuber and Lisson 1981). An increase in blood viscosity and serum cholesterol was found with exposure to high temperatures (Clark and Edholm 1985; Gordon, Hyde and Trost 1988; Keatinge et al. Physically demanding work is related to changes in blood pressure. A problem with drugs, e.g. The resulting acute heart ailments have been repeatedly examined and described according to exposure time, breathing frequency, age and previous illnesses. The effects of “lack of movement” as a risk factor for cardiovascular disease and of physical activity as promoting health were elucidated in such classic publications as those by Morris, Paffenbarger and their co-workers in the 1950s and 1960s, and in numerous epidemiological studies (Berlin and Colditz 1990; Powell et al. The body’s normal inflammatory response involved proliferation of surrounding cells and infiltration of the tissue with new cells. this essay is not unique. These all can lead to a cancer, especially lung cancer. In addition to the clearly direct cardiotoxic effects, arteriosclerotic changes in the brain, eye, kidney and coronary vasculature that can be considered the basis of encephalopathies, aneurysms in the retina area, nephropathies and chronic ischaemic heart disease have been proven among those who are exposed to CS2. In 1954, Foulds ( 8 ) individualized a third stage that he termed ‘progression’, in order to account for all post-initiation events that occur during carcinogenesis. A chemical hazard is a hazard that can be caused through chemicals in the air and on surfaces at the workplace. biological carcinogens INTRODUCTION Carcinogen is any substance (radioactive or radiation) that is directly involved in the cause of cancer. A series of epidemiological studies, spurred on by the studies of Morris et al. The results of studies to date are also not consistent on the question of whether heavy physical work is related to the onset of arterial hypertension. A teratogen is anything that may cause a problem with an embryo. 1993; Pelmear, Taylor and Wasserman 1992). Published in Physical, Chemical and Biological Hazards Read more... " DISCLAIMER: The ILO does not take responsibility for content presented on this web portal that is presented in any language other than English, which is the language used for the initial production and peer-review of original content. The cause is therefore suspected to be “rebound vasospasm”. A physical hazard is a hazard that can be caused in the environment you are in and it can cause harm to you. 1) is derived primarily from studies of animal models. 1990); more frequent (68%) among chronic Q-fever
with weak immune system or pre-existing heart disease
(Brouqui et al. However, the danger threshold for indirect effects (e.g., from the magnetic field force action on ferromagnetic materials) lies lower than that for direct effects. Chronic exposure to loud noise has been shown to result in a reduction of magnesium content in serum, erythrocytes and in other tissues, such as the myocardium (Altura et al. Workplaces with exposure to cold should pay special attention to appropriate dress and avoiding drafts (Kristensen 1994). 1989). The Raynaud’s phenomenon is pathogenetically based on a vasomotor disorder. 1994). Carcinogens • Agents causing cancer (thro’ genetic damage) • Classification • Chemical • Physical • Hormonal • Biological • History: • 18th Century Sir Percival Pott • Scrotal skin cancer in … Experimental studies have shown that with regular motion training, the known risk factors and other health-related factors are positively influenced. This includes ailments ranging from angina pectoris up to acute myocardial infarction and cases of sudden death. Selection of activities and industrial branches that may be associated with cardiovascular hazards, Rayon and synthetic fiber fabrication, rubber, matches, explosives and cellulose industries Used as solvent in manufacture of pharmaceuticals, cosmetics and insecticides, Explosives and munitions manufacture, pharmaceuticals industry, Employees in large industrial combustion facilities (blast furnaces, coke ovens) Manufacture and utilization of gas mixtures containing CO (producer gas facilities) Repair of gas pipelines Casting workers, firefighters, auto mechanics (in badly ventilated spaces) Exposures to accidents (gases from explosions, fires in tunnel building or underground work), Smelting of lead ore and secondary raw materials containing lead Metal industry (production of various alloys), cutting and welding metals containing lead or materials coated with coverings containing lead Battery factories Ceramics and porcelain industries (production of leaded glazes) Production of leaded glass Paint industry, application and removal of leaded paints, Solvents (paints, lacquer) Adhesives (shoe, rubber industries) Cleaning and degreasing agents Basic materials for chemical syntheses Refrigerants Medicine (narcotics) Methyl chloride exposure in activities using solvents. One theory holds that the physical particles cause irritation in the surrounding tissue, resulting in inflammation. The danger threshold for ferromagnetic implants begins at 50 to 100 mT. Chemical. Deadly infarctions were observed among those with previous afflictions at 20% CO-Hb (Atkins and Baker 1985). Little is known about the arrhythmia-triggering dosage of the individual substances, as the reports on humans predominantly are case descriptions with exposure to high concentrations (accidental exposure and “sniffing”). According to Reinhardt et al. In previous studies, no direct cause-and-effect relationship could be shown between lack of movement and the rate of cardiovascular disease or mortality.

Studies show that the noise risk factor for diseases of the cardiovascular system is less significant than behavioural risk factors like smoking, poor nutrition or physical inactivity (Aro and Hasan 1987; Jegaden et al. Examples are polycyclic aromatic hydrocarbons, aromatic amines, N-nitrosamines. The following relative risks were calculated for the onset of a myocardial infarction within one hour of heavy physical strain in comparison with light activity or rest: 5.9 (CI 95%: 4.6-7.7) in the American and 2.1 (CI 95%: 1.6-3.1) in the German study. 1994), Relatively frequent with malaria tropica (Sundermann 1987); direct
