Hydrocarbon-inducible cytochrome P4501A (CYP1A) expression was measured, as ethoxyresorufin-O-deethylase (EROD) activity, in livers of wintering harlequin ducks (Histrionicus histrionicus) captured in areas of Prince William Sound, Alaska, USA, oiled by the 1989 Exxon Valdez spill and in birds from nearby unoiled areas, during 2005 to 2009 (up to 20 years following the spill).

The ship-breaking industry is booming, but official India is only half-concerned about the many hazards. (Editorial)

Persistent organic pollutants (POPs)

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

This study evaluated the associations of body burden levels of dioxins and related compounds with the prevalence of metabolic syndrome among the general population in Japan.

Persistent pollutants, such as polychlorinated biphenyls (PCBs), affect endocrine function. Human exposure to polybrominated diphenyl ethers (PBDEs), which are similar in structure to PCBs, has increased recently, but health effects have not been well studied.

Bone toxicity has been linked to organochlorine exposure following a few notable poisoning incidents, but epidemiologic studies in populations with environmental organochlorine
exposure have yielded inconsistent results. The aim of this study was to investigate whether organochlorine exposure was associated with bone mineral density (BMD) in a population 60

Noble metals and Cu mainly are recycled in treating waste printed circuit boards (PCBs), and a large amount of nonmetallic materials in PCBs are disposed of by combustion or landfill, which may cause secondary pollution and resource-wasting. In this study, a kind of nonmetallic plate (NMP) has been produced by nonmetallic materials of pulverized waste PCBs. The NMP is produced by a self-made hot-press former through adding resin paste as a bonding agent.

Lawmakers are again asserting that the Bush Administration is meddling in science. House Science Committee Democrats charge that federal officials have suppressed a report on potential health threats from pollution in the Great Lakes. They also say officials at the U.S. Centers for Disease Control and Prevention (CDC) in Atlanta, Georgia, may have punished a career federal scientist who oversaw it. CDC says the report had genuine scientific flaws.

The article discussses the health effects of polychlorinated biphenyls (PCB). Between 1960 and 1977 Monsanto's Newport plant produced several types of PCB, that are persistent and ubiquitous and toxic.
