Accumulation of organochlorine compounds is well studied in aquatic food chains whereas little information is available from terrestrial food chains. This study presents data of organochlorine levels in tissue and plasma samples of 15 critically endangered Iberian lynx (Lynx pardinus) and other 55 wild carnivores belonging to five species from three natural areas of Spain (Doñana National Park,...

Levels of six PCB congeners and seven organochlorine pesticides were investigated and compared in ambient air and in pine needle samples. The applied methods are suitable for the analysis of PCBs and organochlorine pesticides in environmental samples and for their detection in recent intakes. DDE, HCB, lindane, PCB-28, PCB-52, PCB-101, PCB-138 and PCB-153 were found in all pine needle and air s...

Organochlorine pesticides such as DDT were long ago banned in America and Europe but due to their persistence their metabolites are still detected in the environment. In Greece, organochlorine insecticides such as DDT were extensively used before 1972 (Albanis et al. 1994). Coastal wetlands, which are widespread in Greece, are areas where pesticides from the agricultural activities of extensive...

A comparison of the performances of ammonia and methane as reagent gases for the analysis of trace organochlorine compounds by gas chromatography coupled to negative-ion chemical ionization mass spectrometry is performed in the present study. Examples of standard mixtures and human blood samples analyzed with both reagents in scan and selected-ion monitoring mode are shown. Important advantages...

Many thousand organic compounds are in common use and new ones introduced daily. With many of these materials, little is known about their toxic hazard. For years scientists have been investigating the relation of structure and properties to biological activity. Among the factors relating to toxicity are bioaccumulation and persistence in the organism. In this study, the relation of partition c...

Managing urban pests with “environmentally-friendly” compounds has gained importance in recent years with the global deregistration of persistent organochlorine insecticides. Boron compounds, especially boric acid, zinc borate, and disodium octaborate tetrahydrate, are considered excellent options for preserving lumber from insect attack as well as decay by fungi and bacteria. Remedial borate a...

Biomarkers of organochlorine pesticides were measured in both venous and umbilical cord blood from 35 pregnant Hispanic women living in Brownsville, Texas, USA. Gas chromatography with an electron capture detector was used to analyze specimens for 30 individual pesticides or their metabolites. Results indicate that blood concentrations were relatively low for most individual compounds, but that...

Due to their bioaccumulative and persistent nature, determination of PCB and organochlorine pesticide levels in human adipose tissue can be a useful biological indicator of exposure. The analytical methods previously used are relatively tedious, labor intensive and not readily amenable to automation. We have combined the use of sweep codistillation cleanup [1] and high resolution gas chromatogr...

background: the presence of organochlorine pesticides in the environment is a serious threat to human health and requires continuous monitoring. therefore, in the present systematic review, the residual amount of different organochlorine pesticides in human samples has been investigated.   methods: all accessible databases in english and farsi were searched by using organochlorine and related p...

A little over a decade ago, Waldichuk (1990) reviewed the state of industrial and domestic pollution of the North Pacific and concluded that interfaces (e.g., air-water, water-sediment, shorelines) and coastal areas, especially those surrounded by dense population and industry, were most at risk. His list of critical contaminants – hydrocarbons and polynuclear aromatic hydrocarbons (PAHs), orga...
