Environmental Health: Health effects of low-concentration POPs ■ Body Storage of POPs The toxicity of individual chemicals belonging to POPs at high concentrations has been well known for a long time. Recently, there's been growing concern about the health risks associated with chronic exposure to low concentrations of POPs in the environment. Human exposure to POPs typically involves exposure t..

Environmental Health: Dioxins and cancers TCDD, a type of PCDD substance, is recognized as the most toxic, with chlorine typically present in PCDD. Higher numbers indicate greater toxicity. In the 1980s, exposure to TCDD occurred among workers due to accidents or occupational exposure. Measurements showed TCDD concentrations 10 to 100 times higher than typical daily exposure, particularly in ind..

Dioxins A type of persistent organic pollutants (POPs) Dioxin is a substance that occurs naturally due to incomplete combustion such as volcanic activity or forest fires, or is created as an impurity during the synthesis of chlorine and aromatic hydrocarbons, and is frequently exposed in combustion processes such as waste incineration. The International Agency for Research on Cancer (IARC) class..

Radon and Lung cancer Radon is a substance known to cause cancer in humans (Group 1), according to the International Agency for Research on Cancer (IARC). Radon comes from rocks, soil, water, and building materials and can seep into indoor spaces. Since it can build up indoors, it's important to vent it outside to reduce exposure. Radon is a major cause of lung cancer. When we breathe in radon, ..

Outdoor air pollution and other cancers From 1978 to the end of 2003, a follow-up study was conducted on cancer occurrence among bus drivers in three Danish cities. The study involved 2,037 subjects, among whom 70% of men were smokers. The incidence rate (SIR) for all cancers was 1.09 (95% CI, 1.0-1.2), with bladder cancer risk being 1.6 times higher (95% CI, 1.2-2.0) compared to the non-exposed..

Outdoor air pollution and lung cancer According to the International Agency for Research on Cancer (IARC), certain substances are classified as carcinogenic to humans (Group 1). Particulate matter found in the air, including PM10 (particles with a diameter of 10 micrometers or less) and PM2.5 (particles with a diameter of 2.5 micrometers or less), is categorized as fine dust. Air pollutants, whe..

Health Effects of Cadmium Cadmium is a metal found on the Earth's surface and is usually found with zinc, lead, and copper. This metal is silver-white, soft, and toxic. Cadmium is used as a coating material to prevent corrosion and is also used in batteries and pigments. However, cadmium mainly comes as a by-product from the production of zinc, lead, and copper. Cadmium and its compounds are kno..
