Organochlorine Pesticide Residue in Fish Fillets From Lake Springfield, Missouri
A method for extracting organochlorine pesticides from fish fillets using solid phase extraction techniques was developed. Fish fillets (10 and 20 g) were ground with 20 g of anydrous sodium sulfate. This mixture was then extracted with 100 mL of hexane, filtered and passed through a Chem Elut …

A Multi-Scale analysis of organochlorine pesticide contamination in raptor populations: research effort, historical trends, and current concentrations
Pesticide contamination and the associated impacts on biodiversity, have been the focus of intense research and tremendous concern for environmental and conservation scientists over many decades. The environmental consequences of organochlorine pesticides, particularly …

Pesticides in the Aquatic Environment
Pesticides are ubiquitous contaminants of the freshwater aquatic environment. Pesticide residues are found in varying amounts in all components of the aquatic ecosystem including water, animal and plant tissue and sediments. Organochlorine pesticide residues in water, usually in the parts per …

Chronic effects of single intra-peritoneal injection of endosulfan on rainbow trout (Oncorhynchus mykiss) and field observations of caged rainbow in Oshawa Creek
The organochlorine pesticide endosulfan has been shown to be highly toxic to fish and there is some evidence to support that it may act as an endocrine disrupting chemical. Juvenile rainbow trout (Oncorhynchus mykiss) were caged at 4 sites in Oshawa Creek during the fall and spring of 2008 and 2009 …

Effects of methoxychlor and its metabolites on mouse antral follicles
… are exposed to numerous chemicals including organochlorine pesticides that are introduced into the environment on a daily basis. Some of these chemicals exert their toxicity by binding to estrogen receptors in inappropriate manners or by inhibiting the ability of endogenous estrogen to bind …

The use of cultured cells with defects of citrulline metabolism in diagnosis and in the study of intercellular communication
… Tumor promoters such as phorbol esters and organochlorine pesticides have been reported to inhibit intercellular junctional communication in other systems, and this inhibitory activity may be related to the mechanism of tumor promotion. The organochlorine pesticide 1,1,1-trichloro- …

Blood characteristics as predictors of reproductive success in quail species exposed to DDT
… capable of assessing both contamination with an organochlorine chemical and reproductive success without the need for removing individuals from that population. Experiments were performed to evaluate vitellogenin, vitamin A, and vitamin E as biomarkers of contamination with DDT, an organochlorine …

Mechanism of methoxychlor toxicity in mouse ovarian antral follicles
… (methoxychlor; MXC) is an organochlorine pesticide used against pests and insects that attack crops, gardens, vegetables, pets, and livestock. MXC targets the ovary and its exposure has adverse effects on reproductive function in adult female mice causing persistent estrus, …

ORGANIC MICROPOLLUTANTS ANALYSIS AND THEIR METROLOGICAL TRACEABILITY TO SI UNITS
… and on two organic molecules: - endosulfan, an organochlorine pesticide banned in 2011 due to its toxicity, analysed in green tea; - melamine, a molecule commonly used in the plastic industry which became famous for its fraudulent use as adulterant of the protein content of milk in 2008. Ad hoc …
