Fourteen pesticides (fungicides, herbicides, and insecticides) were tested to determine whether they had deleterious effects on the bioinsecticide Bacillus popilliae, the causal agent of milky disease. All of these pesticides reduced levels of spore viability, spore germination, and/or vegetative cell growth when they were tested over a range of concentrations from 0 to 1,000 ppm of active ingr...

Air samples collected during 1994–2000 at the Canadian Arctic air monitoring station Alert (8230 N, 6220W) were analysed by enantiospecific gas chromatography–mass spectrometry for αhexachlorocyclohexane (α-HCH), trans-chlordane (TC) and cis-chlordane (CC). Results were expressed as enantiomer fractions (EF = peak areas of (+)/[(+)+ (−)] enantiomers), where EFs = 0.5, < 0.5 and > 0.5 indicate r...

Selected organochlorine pesticides (OCs) and halogenated flame retardants (HFRs) were analyzed in surficial fjord sediments collected down the length of Kongsfjorden, Svalbard in the Norwegian high Arctic. Hexachlorocyclohexane (α-HCHs) was found to be the most abundant OC in the sediment, followed by BDE-209>chlordane>α-endosulfan>Dechlorane Plus (anti-DP)>trifluralin concentration ranges were...

It is known that the consumption of seafood has several health benefits for humans. However, accumulation organic pollutants, such as polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCPs), in their flesh could pose public problems. Thus, concentrations PCBs OCPs edible fish species (Mugil bananensis, Sarotherodon melanotheron) from Sine Saloum Estuary located central-western Sen...

This study evaluated the concentrations of organochlorine pesticides (OCPs) in inlet and outlet treatment plant Ahvaz city. For this purpose, six OCPs, including chlordane, dieldrin, dichlorodiphenyltrichloroethane, heptachlor, lindane, endrin were measured at three different sites during, 12 months. A gas chromatograph-mass spectrometer (GC-MS) device was applied for analysis determination tar...

Abstract The major nesting sites for the endangered green turtle ( Chelonia mydas ) are in Campeche, Mexico: Carmen, Isla Aguada, and Sabancuy. Although they a natural reserve, these threatened by agricultural activities oil extraction. This study aimed to determine presence concentration of organochlorine pesticides (OCPs) polycyclic aromatic hydrocarbons (PAHs) plasma eggs assess antioxidant ...

Muscle samples were collected from pup, juvenile and adult Weddell seals (Leptonychotes weddellii) near McMurdo Sound, Antarctica during the austral summer of 2006. Blubber samples were collected from juvenile and adult seals. Samples were analyzed for emerging and legacy persistent organic pollutants (POPs) including current and historic-use organochlorine pesticides, polychlorinated biphenyls...

BACKGROUND Fetal poisoning of California sea lions (CSLs; Zalophus californianus) has been associated with exposure to the algal toxin domoic acid. These same sea lions accumulate a mixture of persistent environmental contaminants including pesticides and industrial products such as polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs). Developmental exposure to the pestic...
