The “white finger disease”, first described by Raynaud, appears with higher prevalency rates among exposed populations, and is recognized as an occupational disease in many countries. You can get 100% plagiarism FREE essay in 30sec, Sorry, we cannot unicalize this essay. 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. 1987). 1986; Lloyd 1991; Neild et al. These results were attributed to a possible healthy worker effect among the heat-exposed workers. 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. The participation of the heart can appear either during or after the actual infection. Physically demanding work is related to changes in blood pressure. For this reason it appears all the more urgent to study the effect of multiple burdens at the workplace and to clarify the cross effects, mostly unknown up to now, between combined influencing exogenous factors and diverse endogenous risk characteristics. 1987). 5. This includes ailments ranging from angina pectoris up to acute myocardial infarction and cases of sudden death. 1993; Marshall and Bilderling 1984). 1973) and a glass factory in Canada (Wojtczak-Jaroszowa and Jarosz 1986). The relative significance of cold, noise and other physical and psychological stressors, and heavy nicotine consumption is still unclear in the development of the Raynaud’s phenomenon. All these are hazardous as they are all bad chemicals bad for the health of a human. As pathomechanisms the direct germ colon- ization or toxic or allergic processes should be considered. In certain epidemiological studies, suspected associations between exposure duration and intensity of organic nitrate and ischaemic heart disease are considered uncertain, and pathogenetic plausibility for them is lacking. We can custom edit this essay into an original, 100% plagiarism free essay. PRE-ORDER TODAY! 1993; Pelmear, Taylor and Wasserman 1992). A large epidemiological study of women textile workers in China (Zhao, Liu and Zhang 1991) plays a key role in noise effect research. Search keywords included a combination of: waterpipe, narghile, hookah, shisha along with names of chemical compounds and classes of compounds, in addition to terms commonly used in cellular biology and aerosol sizing. Pssst… Using an additive logistical model the factors “indicated cooking salt use”, “family history of high blood pressure” and “noise level” (<<0.05) significantly correlated with the probability of high blood pressure. Category 2 carcinogens are suspected human carcinogens. However, the hypothesis that halogenated hydrocarbon acts as a myocardial irritant is considered certain. Hearing loss due to workplace noise has been recognized as an occupational disease for many years. In the magnetic field, such as in the blood stream or during heart contraction, charged carriers lead to induction of electrical fields and currents. Whereas among healthy subjects, cardiovascular effects first appear at CO-Hb concentrations of 35 to 40%, angina pectoris ailments could be experimentally produced in patients with ischaemic heart disease already at CO-Hb concentrations between 2 and 5% during physical exposure (Kleinman et al. Temperature proved to be the strongest, acute (day to day) predictor for cardiovascular mortality under the parameters which were handled differently, such as seasonal environmental changes and factors like air pollution, sunlight exposure, incidence of flu and nutrition. In Japan, vascular changes in the area of the retina were found, whereas in Finland the cardiovascular effects dominated. The Globally Harmonized System (GHS) divides hazardous chemicals in the workplace into different categories: physical hazards, health hazards, and environmental hazards (see Table 1 ) (GHS 2007 ). Concerning lead, metallic lead in dust form, the salts of diva- lent lead and organic lead compounds are toxicologically impor- tant. Since the half-life of the organic nitrate is short, the ailments soon subside. 1. An increase in the noise level from 70 to 100 dBA raised the risk for high blood pressure by a factor of 2.5. 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. Most cold-related deaths occurred in people with cardiovascular diseases, and most heat-related deaths were associated with respiratory tract illnesses. They can themselves be a cause or contributing factor in a developing disease. Some of the dioxin and PCB congeners may be carcinogens at low levels of exposure over extended periods of time. Raynaud’s phenomenon is marked by an attack with vasospastic reduced fusion of all or some fingers, with the exception of the thumbs, accompanied by sensibility disorders in the affected fingers, feelings of cold, pallor and paraesthesia. The calculation of the aetiological role of chemical occupational factors for cardiovascular diseases for the Danish population resulted in a value under 1% (Kristensen 1994). The effect of workplace noise on blood pressure is equivocal. 1995). The traditional view of carcinogen-esis (Fig. Table 1 gives an overview of possible occupation-related infectious diseases that affect the cardiovascular system. It may cause short or long term health problems. The figures were statistically significant for blood diseases, high blood pressure, ischemic heart disease and respiratory tract diseases. 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. A cohort mortality study in the United States showed a 10% lower cardiovascular mortality for heat-exposed workers as compared to the non-exposed control group. 1995). (1993) in a cohort study of French steel workers. 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). Five categories of cancer forming agents can be identified. It may also cause mental problems and retardation. 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 ). 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.

Xanax (Alprazolam), may cause significant memory loss, brain damage, lack of concentration. 1992; Petiot et al. It results, for example, in an increase in the HDL-cholesterol level, and a decrease in the serum-triglyceride level and blood pressure (Bouchard, Shepard and Stephens 1994; Pate et al. Bacteria, viruses, fungi and protozoa are among the biological hazardous materials that can harm the cardiovascular system through contact that is intentional  (introduction of technology-related  biological  materials)  or  unintentional  (non-technology-related contamination of work materials). It may also lead straight to low weight when born and health problems in the child’s future. It is long known and well documented that vibrations transmitted to the hands by vibrating tools can cause peripheral vascular disorders in addition to damage to the muscle and skeletal system, and peripheral nerve-function disorders in the hand-arm area (Dupuis et al. 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). Assessing the physical load, often solely on the basis of job descriptions, must be seen as an inadequate method. The highest relative risk for cardiovascular diseases was found in people with physically inactive jobs (e.g., sitting jobs) as compared to people who do heavy physical work. The Raynaud’s phenomenon is pathogenetically based on a vasomotor disorder. Despite the f… It is not yet clear how these results should be interpreted. Comparable results were cited by Moulin et al. Data sources: Peer-reviewed publications indexed in major databases between 1991 and 2014. Physical Hazards. A teratogen is anything that may cause a problem with an embryo. November 23, 2020. 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… The indications are mounting that noise and the risk factors—increased blood pres- sure, increased serum cholesterol level (Pillsburg 1986), and smoking (Baron et al. It should be mentioned that cold stress is not only a function of temperature. Studies that enlist hearing loss as a surrogate for noise show varied results. Alcohol is a known teratogen. AVAILABLE SOON! In any case, hearing loss is not a suitable biological indicator for noise ex- posure (Kristensen 1989; van Dijk 1990). 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. The Ames test is a widely used test to screen chemicals used in foods or medications for mutagenic potential. It has been estimated that exposure to environmental chemical carcinogens may contribute significantly to the causation of a sizable fraction, perhaps a majority, of human cancers, when exposures are related to "life-style" factors such as diet, tobacco use, etc. Among these is tem- porary hypertension that appears with lead colic. These all can lead to a cancer, especially lung cancer.

As the particle remains in place and the normal tissue continues to undergo proliferation, some cells mutate into neoplastic (canc… GradesFixer. Visual (induced with magnetophosphene) and nervous effects are reported at 10 to 100 mA/m2. Physical Properties: The physical properties include texture, structure, and colour. The risk is clearly greater with vibrations from machines with higher frequencies (20 to over 800 Hz) than with machines that produce low-frequency vibrations. This can affect virtually all occupational groups after a workplace accident. The observations make clear that statements on possible causal relationships between heavy physical labour and effects on cardiovascular morbidity are not easy to substantiate. Lead seems to affect blood pressure and cerebrovascular morbidity. Heat will hurt a human because it may cause first, second or third degree burns. Primary and secondary selection processes (healthy worker effect) can lead to serious distortions in occupational medical epidemiological studies. Another mutagen is from going to too many X-rays as this will cause your cells to mutate and cause cancer. 1987)—have a synergistic effect on the de- velopment of noise-induced hearing loss.

According to currently available data, no direct health threat is to be expected for short-term whole-body exposure up to 2 T (UNEP/WHO/IRPA 1987). Table 1. In facilities in research and industry with strong magnetic fields, some authors advise medical surveillance examinations for people with cardiovascular diseases, including high blood pressure, in jobs where the magnetic field exceeds 2 T (Bernhardt 1986; Bernhardt 1988). Four substances have been added in the U.S. Department of Health and Human Services 13th Report on Carcinogens, a science-based document that identifies chemical, biological, and physical agents that are considered cancer hazards for people living in the United States. The design of this study is not known. A hazard is anything with the potential to cause bodily injury, and includes any physical, chemical, biological, mechanical, electrical, or ergonomic hazard. Are you interested in getting a customized paper? Ethnic and nutritionally related components interfere in the pathomechanism; this was made clear in the comparative studies of Finnish and Japanese viscous rayon workers. Changes in blood pressure such as hypertension are mostly traceable to vascular-based changes in the kidney, a direct causal link to high blood pressure due to carbon disulphide has not yet been excluded for certain, and a direct (reversible) toxic effect is suspected on the myocardium or an interference with the catecholamine metabolism. Students who find writing to be a difficult task. 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. In dynamic work that utilizes big muscle masses, blood supply and demand are in balance. 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. These hazards can vary from a microorganisms, viruses or toxins. A selection of relevant activities and industrial branches can be found in Table 1. Your risk of cancer can increase through exposure to cancer-causing agents, also referred to as ‘carcinogens’. A successful 15-year intervention study (Nurminen and Hernberg 1985) documents the reversibility of the effect on the heart: a reduction in exposure was followed almost immediately by a decrease in cardiovascular mortality. Examples are polycyclic aromatic hydrocarbons, aromatic amines, N-nitrosamines. (1970) among American harbour workers, looked at the relationship between the difficulty level of physical work and the incidence of cardiovascular diseases. Bosses make sure to check each worker to see how much they have been exposed to as the more amount you have been exposed to, the more dangerous for your health it is. The body’s normal inflammatory response involved proliferation of surrounding cells and infiltration of the tissue with new cells. Physical transformations of solid waste typically involve a change of phase. After the exposure ends, circulation resumes, accompanied by a painful hyperaemia. The effects described in the literature appear to be influenced by a combination of factors like muscle activity, dress, dampness, drafts and possibly poor living conditions. The results of epidemiological studies do not permit any final answer on the adverse cardiovascular health effects of chronic workplace or environmental noise exposure. Pathogenetically this is a chronic-traumatic damage to the artery ulnaris (intima lesion with subsequent thrombosization) in the area of the superficial course above the unciform bone (os hamatum). An … Wild et al. Based on earlier studies from the 1950s and 1960s the prevailing idea was that physical activity at work could have a certain protective effect on the heart. We’ve got you covered. 0. A biological hazard is a hazard that can cause harm to a human or a living organism. There is little, if any, epidemiological evidence to support the hypothesis that the risk of cardiovascular disease is higher in populations with an occupational, long-term exposure to high temperature (Dukes-Dobos 1981). 1990); 67% (Higuchi et al. Include the specific name of the chemical, not just the group of chemicals, and the specific type of mutation is causes. Having trouble finding the perfect essay? Whether the vibration directly causes damage to the vascular musculature (a “local fault”), or whether it is a vasoconstriction as a result of sympathetic hyperactivity, or whether both these factors are necessary, is at present still unclear (Gemne 1994; Gemne 1992). In the studies (Talbott et al. Karnaukh et al. A carcinogen can alter the genomic integrity of living beings, can cause metabolic alteration, or interfere with the physiological functions of healthy cells to … * • Mutagenn* are Classified into, physical mutagens, chemical mutagens, and biological agents. 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. 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. Carcinogens • Agents causing cancer (thro’ genetic damage) • Classification • Chemical • Physical • Hormonal • Biological • History: • 18th Century Sir Percival Pott • Scrotal skin cancer in … The effects can be difficulty breathing or get irritation on your skin, flammable, explosive or affect the environment. 1986). One theory holds that the physical particles cause irritation in the surrounding tissue, resulting in inflammation. 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. To protect yourself, make sure you are wearing a mask and make sure that you check the compressed gas before using it. The degree of these reactions is modified by such factors as the type of noise occurrence, age, sex, state of health, nervous state and personal characteristics (Harrison and Kelly 1989; Parrot et al. The work-related hypothenar hammer syndrome (HHS) should be distinguished in the differential diagnosis from vibration-caused Raynaud’s phenomenon. The opinion is advanced in modern stress research that although increases in blood pressure during work are connected to noise exposure, the blood pressure level per se depends on a complex set of personality and environmental factors (Theorell et al. Limited Supply While They Last! 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. 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. Reducing the exposure to 10 ppm clearly reduced cardiovascular mortality. 1991), Workers in meatpacking, fish

If you smell gases, make sure you go to someone for help or open some doors and windows to let out the gas. 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. 1988). We will occasionally send you account related emails. We provide you with original essay samples, perfect formatting and styling. Whereas experimental studies on animals possibly showed an atherogenic effect by way of hypoxia of the vasa walls or by direct CO effect on the vasa wall (increased vascular permeability), the flow characteristics of the blood (strengthened thrombocyte aggregation), or lipid metabolism, the corresponding proof for humans is lacking. Neurotoxicity is a form of toxicity in which a biological, chemical, or physical agent produces an adverse effect on the structure or function of the central and/or peripheral nervous system.
