چکیده
ORGANOHALOGEN COMPOUNDS – Volume 66 (2004) 1500 Introduction Toxaphene and mirex are the members of persistent organic pollutants (POPs) included in the International Treaty, the Stockholm Convention. POPs are characteristically transferred across borders and are accumulated in wildlife. Consequently, their global distribution and biological impacts are of great concern. However, there is very little information on contamination by toxaphene and mirex in the Asia-Pacific region. In Japan, scientific research focused on these two pesticides has not been conducted so far since they have never been registered there. In this study, toxaphene and mirex were determined in the blubber of cetaceans collected from various regions with a focus on Asian countries to evaluate the effects of their long-range atmospheric transport from regions where they were extensively used.

Current Status and Regulatory Aspects of Pesticides Considered to be Persistent Organic Pollutants (POPs) in Taiwan
Organochlorine pesticides (OCPs) are capable of persisting in the environment, transporting between phase media and accumulating to high levels, implying that they could pose a risk of causing adverse effects to human health and the environment. Consequently, most OCPs are designated as persistent organic pollutants (POPs) and even as endocrine disrupting chemicals (EDCs). The objective of this...

Residues of two organochlorines (OCs) -Aroclor 1268 (a highly chlorinated PCB formulation) and toxaphene (a DDT-replacement pesticide) -are major persistent contaminants in St. Simons Sound near Brunswick, Georgia, USA. Although studies have recently documented OC levels in Brunswick area fish that are routinely consumed by humans, little is known about organochlorine body burdens in resident m...

BACKGROUND Persistent organic pollutants (POPs), including polychlorinated biphenyls (PCBs) and chlorinated pesticides, have been shown to have many adverse human health effects. These contaminants therefore may pose a risk to Alaska Natives that follow a traditional diet high in marine mammals and fish, in which POPs bioaccumulate. METHODS AND FINDINGS This study examined the levels of PCBs ...

Background: Oily fish and their extracted oils may be a source of polychlorinated biphenyls (PCBs) which can induce toxic effects on the consumers. The main aim of this survey was estimation of PCBs intake through fish oil-derived dietary supplements and prescription drugs in the Japanese population. Methods: PCBs levels were determined in 20 fish oil-derived dietary supplements and 6 oil-deri...

Little is known about levels or effects of persistent organic pollutants (POPs) in Hawaiian monk seals (HMS) from the main Hawaiian Islands (MHI) subpopulation. This study examined concentrations of a large suite of POPs in blubber and serum of juvenile and adult HMS from the MHI. Adult females have the lowest blubber levels of most POPs, whereas adult males have highest levels. POPs in serum w...
