Dioxin from a group of highly toxic chemical compound that can cause cancer. Due to the stability of this chemical, the dioxin is not easily to break down and can remain in the body for a long time. Once in the body, it may take between 7 and 11 years for a dioxin's radioactivity to fall to it half-life. This dioxin also can be transfer into the body by the air and dust into the lung. Over 90% of human exposure to dioxins comes through food, mainly animal products, such as dairy, meat, fish, and shellfish.
Type of Dioxin:
- Chlorinated dibenzo-p-dioxins (CDDs)
- Chlorinated dibenzofurans (CDFs)
- some Polychlorinated biphenyls (PCBs)
Properties of Dioxin:
- Colourless and odourless
- Chemical resistant
Dioxin can be found by product of:
- Burning rubbish
- Iron/steel product
- Chlorine bleaching of pulp and paper
- Production of pesticides and herbicides
- Dismantling and recycling electronic products
- Chemical industry
How does the Dioxin effect environmental?
- Dioxin can absorb into the soil and plant.
- Dioxin can enter into the underground water.
- By entering our food chain when livestock eat something contaminated with Dioxin and remain in it fats and continue until consume by human.
- It may be disperse through airborne.
Diseases and acute or short-time exposure effect cause by Dioxin:
– Weight loss
– Skin rashes & discolouration
– Birth defects
– Excessive body hair
– Cigarette smoke also contains small amounts of dioxins.
– Firefighter are more often to exposed or contaminated with dioxin when operation of extinguishing fire.
