What is the connection between dioxins and cancer?

dioxins and cancer are directly related to a high level of exposure. Government agencies that study and regulate the health risks of chemicals have upgraded the connection between dioxins and cancer by dioxins classification as a well -known human carcinogen. Exposure of high levels of dioxins can cause cancer of the lymphatic system, breast, gallbladder and blood and sarcomas soft tissues. The connection between dioxins and cancer at a low exposure level was not scientifically determined.

Hundreds of dioxins exist in an environment and are created by chemical compounds based on chlorine that contaminate air, water and soil. The type considered the most toxic and studied dioxins and cancer researchers is called tetrachlorodibenzo-dioxin (TCDD). The connection between all other forms of dioxins and cancer is examined in relation to the well -known toxic effects of TCDD.

Dioxins are formed by burning waste to landfills and from refining and melting processes on metal manufacturing plants. The bleach process used inPaper and pulp industries also produce dioxins. These chemicals exist in cigarette smoke, pesticides, herbicides and preservatives. Most of the exposure of human dioxins come from food contaminated chemicals.

The meat contains the highest levels of dioxins that occur most often in beef beef, followed by chicken, pork and oily fish. Dairy products such as cheese, butter, milk, eggs and ice cream may also be tainted with dioxins. People who live near refineries, paper mills or municipal landfills can inhale through air contaminated with chemicals.

One of the most famous dioxins and cancer studies examined the use of Agent Orange by the US Army in Southeast Asia during the Vietnam War. Herbicide was sprayed with immense jungle expansion to kill plants hiding enemy units. Vietnamese veterans exposure to a high levelTCDD showed an Orange agent a higher level of cancer and other health disorders.

Scientists believe that TCDD promotes the growth and spread of tumors by biochemical cell change. These studies have found an increased level of cancer at levels previously considered non -toxic. Another study found similar results of the use of herbicides.

inhabitants of TCDD exposure in Italy Seveso, when the herbicide plant exploded in 1976, later developed various cancer. Scientists examined the distance from the explosion and levels of dioxins found in the soil and water to assess the connection between dioxins and cancer. They compared cancer levels 10 years after misfortune with areas that escaped contamination, because cancer usually lasts so long or more.

dioxins also exist in plastic polyvinyl chloride (PVC) and may be present in some plastic food containers. Health experts recommend the re -use of plastic containers designed for one -time use, such as margarine bathtubs, in a microwave. TeThe area can release dioxins into food. For this use, plastic food packaging used in microwave furnaces should be specially produced and thin plastic, such as plastic food bags, should be avoided.
