Many chemicals are dangerous to human and ecosystem health. Among the worst is a range of synthetic organic compounds that persist in the environment for long periods of time. GEF

The Obama administration said on Friday it will keep a Bush-era rule that weakens protection for polar bears' icy habitat and plays down links between the threatened status of the species and climate change.

"Seeing the polar bear's habitat melting and an iconic species threatened is an environmental tragedy of the modern age," US Interior Secretary Ken Salazar said in a telephone briefing.

In the present study, the possibility of biodegrading the dechlorinated product of 1,1,1-trichloro-2,2-bis(4-chlorophenyl)ethane (DDT), 1,1-dichloro-2,2-bis(chlorophenyl) ethylene (DDE) and structurally related compound 1,1-dichloro-2,2-bis(chlorophenyl)-ethane (DDD) under aerobic conditions was examined.

A thaw of the Arctic linked to global warming may slow a drive to get rid of industrial chemicals that are harming indigenous people and wildlife, an expert said on Monday.

State Minister for Environment and Forest Mustafizur Rahman said the government is going to develop a strategy soon for sustainable waste management to keep the environment toxic-free.

California sea lions have a large body burden of organochlorine pesticides, and over the last decade they have also been subject to domoic acid poisoning. Domoic acid poisoning, previously recognized in adult animals, is now viewed as a major cause of prenatal mortality.

The objective of this study was to investigate extent of contamination of groundwater (potable and irrigation) of Aligarh district by pesticides and heavy metals during last 11 years (1996-2006)

No to DDT spray: A Ugandan high court has asked the health ministry to suspend the spraying of ddt in northern part of the country following a petition by nine groups of farmers, traders and conservationists.

policymakers in India swear by the insecticide ddt to contain sand fly, the kala-azar vector. There are alternatives to using chemicals, a group of researchers has found by studying 50 villages in five kala-azar endemic districts in Bihar. The disease is most prevalent in the state. Critics say the study is not foolproof. Various theories exist on sand fly

It has been getting ever harder to pretend that Antarctica is a pristine place. We like to think of it as being scoured clean by hostile winds and extreme cold. But more and more, Antarctica, like the Arctic, shows the lasting scars of human negligence. The effects of climate change are being felt far more strongly at the poles than elsewhere on the planet. Some of the most persistent and dangerous chemicals ever created have accumulated there and remain there.
