Environmental Toxicology Essay

Environmental toxicology calls specific organs as target organs. This is the organ most likely to be exposed to a specific substance. Target organ toxicity is the adverse effect of chemicals on target organs after the target organ has entered the body (Hodgson, 2010). Liver etc. There are many organs aimed only for easy access. Organs that can enter through unprotected cell walls or higher levels of lipids are more likely to be ingested by toxic substances. High flow organs such as the kidneys and liver will receive all the blood and make it easy to filter.

With all these toxic interventions, the liver may overwork and may overcome diseases such as chronic liver disease (Lucile Packard Children's Hospital, 2012).

There are many symptoms that cause chronic liver disease, but they can be divided into 5 groups (chronic liver disease, 2011). The first group is a virus group classification including states such as hepatitis B and hepatitis C (chronic liver, 2011). The second group is metabolome, which includes diseases such as Wilson's disease (chronic liver disease, 2011). The third group is an autoimmune reaction group, which includes patients with primary biliary cirrhosis (chronic liver, 2011). The fourth group is a toxin related group including alcoholism, the last group is a miscellaneous group with diseases such as right heart failure (chronic liver disease, 2011). There is a silent killer among these groups, but this increases the risk of this group. This is a group related to toxins (alcohol chronic liver, 2011), because alcohol dependence causes hepatic cirrhosis of the liver, and then hepatitis. Only one group only needs three people at a time.

Several similarities were found when studying toxic substances and reactions. Many toxic substances can affect lungs, skin and eyes. Take sulfur dioxide, asbestos and gasoline as an example. Sulfur dioxide is a colorless gas with a choking smell and a suffocating temperament (Air Gas, 2012). Even at low concentrations it is toxic to the human body. of

It is an interdisciplinary science field that studies the harmful effects of various chemicals, biological substances and physical factors on living things. It is a sub-field of environmental toxicology dealing with the deleterious effects of hazardous substances at the general population and ecological level. It is important to diagnose health problems such as diagnosis of health problems, poisoning and other drug complications, occupational toxicants, toxic substances in the environment and / or various other biological substances, their management and health The focus is on preventing the adverse effects of. Medical toxicologists personally participate in assessment and treatment of addiction, adverse drug reactions, overdose, substance abuse

Five basic areas of environmental epidemiology, toxicology, exposure science, environmental engineering, environmental law are often contributing to the field of environmental hygiene. Each of these fields provides various information to explain environmental hygiene problems and solutions, but there are some overlapping between them. Environmental epidemiology studies the relationship between environmental exposure (including exposure to chemical substances, radiation, microbial preparations, etc.) and human health. Observational studies investigate only the exposures experienced by people and are common in environmental epidemiology. This is because humans can not be ethically exposed to suspected or suspected drugs causing disease. Although it is the limit of environmental epidemiology that experimental research design can not be used, this field directly observes the influence on human health rather than estimating the impact of animal research.

Three basic areas often contribute to the field of environmental hygiene. Three areas of environmental hygiene are environmental epidemiology, toxicology and exposure science. Each of these fields provides different information to explain environmental health problems, but there is some overlap between them.
