Organochlorine pesticide and total polychlorinated biphenyl (PCB) concentrations were measured in largemouth bass from the Tombigbee River near a former DDT manufacturing facility at McIntosh, Alabama. Evaluation of mean p,p'- and o,p'-DDT isomer concentrations and o,p'- versus p,p'-isomer proportions in McIntosh bass indicated that DDT is moving off site from the facility and into the Tombigbe...

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...

RESULTS—After adjusting for known type 2 diabetes risk factors, including obesity, odds ratios (ORs) (95% CIs) for type 2 diabetes at age 75 years (n = 36) according to the quintiles of a summary measure of concentrations of PCBs (vs. the lowest quintile) were 4.5, 5.1, 8.8 (1.8– 42.7), and 7.5 (1.4–38.8) (Ptrend,0.01). Among organochlorine pesticides, adjusted ORs across concentrations of tran...

Two croaker fish species, Pseudotolithus senegalensis and Pseudotolithus typuswere sampled seasonally from Lagos Lagoon between December 2008 and September 2009 and analysed for pesticide residues. The muscle tissues of the fishes were subjected to cold extraction and subsequently clean-up. The detection and determination of the organochlorine residues were performed using gas chromatography.A ...

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...

Raw buffalo milk samples from the agroindustrial zone in upper Egypt were analyzed for the presence of organochlorine and organophosphorus pesticides using gas chromatography-mass spectroscopy. Five organochlorine pesticides namely, alachlor, dieldrin, hexachlorobenzene, lindane and methoxychlor and three organophosphorus pesticides chlorpyrifos, malathion, and parathion-methyl were detected in...

occurs before 37 wk gestational age. In USA, the preterm delivery rate is 12-13 per cent; in Europe and other developed countries, reported rates are generally 5-9 per cent 1. PTB accounts for 75 per cent of perinatal mortality and it is the leading direct cause of prenatal and neonatal death, resulting in 3.1 million newborn deaths annually. Half of preterm infants have longterm morbidity such...

Elevated levels of DDT and other organochlorine pesticides have been associated with spontaneous abortion and preterm birth in several species, including humans (Delong et al. 1973; Hart et alo 1971; O'Leary et alo 1970; Saxena et al. 1980, 1981; Wassermann et al. 1982). Despite the prevalence of organochlorine pesticides in our environment, a mechanistic basis for this association has not been...

Pesticides are very hazardous and lethal for organisms as well as for humans. They present danger to consumers, bystanders and workers during manufacture, transport or, during and after use. Pesticides are also toxic to plants and many food crops, including fruits and vegetables, contain pesticide residues after being washed or peeled. Pesticides decrease the biodiversity in soil and it has bee...
