PERSISTENT
ORGANIC POLLUTANTS (POPs) |
POPs are chemical substances that persist in the environment,
bioaccumulate through food web, and pose a risk of causing adverse effects to
human health and the environment. These substances consist of pesticides,
industrial chemicals, as well as unintentional byproducts of combustion. The
twelve chemicals are designated as POPs; aldrin, chlordane, DDT, dieldrin,
endrin, heptachlor, mirex, toxaphene, HCB, PCBs, dioxins and furans. POPs are
hazardous to humans due to their three characteristics. Also known as ‘dirty
dozens’, they are;
- Persistent in the environment and fatty tissues of
living organisms
- Able to travel long distances on air and water
- Likely to bioaccumulatein food chain
Improper storage and disposal of above
chemicals cause leakage, spill and evaporation, resulting in human exposure.
These chemicals are assumed to cause cancers, respiratory problems, immune
system defects, birth defects, leaning disorders, as well as skin disorders. The
Stockholm Convention was adopted in Sweden in 2001 for protection human health
and the environment from POPs worldwide. Among the ratifying countries, the
Republic of the Marshall Islands has also acceded the treaty as of
2003.
