Egypt is a major agricultural country in Africa with a known past of organochlorine pesticides (OCPs) application, yet data on atmospheric levels of OCPs in Egypt is sparse. Low density polyethylene (LDPE) passive samplers were therefore deployed for 3 weeks each at 11 locations in July, 2010 and January, 2011 in Alexandria to screen for gas-phase OCPs. Performance reference compounds were used...

Organochlorine pesticide residues and polychlorinated biphenyls were determined in raw materials, fish feeds and fillets from fish exposed through the productive cycle (14 months) to experimental diets with different percentages of fish oil replacement with vegetable oils. Detectable amounts of organochlorine compounds were found in raw materials derived from fish sources with none being detect...

Residues of organochlorine pesticides were determined in soils and drinking water sources in cocoa growing areas in Ghana. Soil samples analysed showed the presence of four organochlorine pesticide residues namely lindane (0.005-0.05 mg/kg), beta-HCH (<0.01-0.05 mg/kg), dieldrin (0.005-0.02 mg/kg), and p,p'-DDT (0.005-0.04 mg/kg), with dieldrin occurring most frequently. Similarly, organochlori...

QuEChERS stands for (Quick, Easy, Cheap, Effective, Rugged and Safe) and pronounced as (catchers) is a method that had been developed for multi-pesticide residue analyses in food. This study was conducted to investigate the efficacy of QuEChERS method for analyzing the organochlorine pesticides residues in cow's milk. Twenty organochlorine pesticide namely (Benzene, 1,3,5-trichloro, Tetrachloro...

Organochlorines were examined in liver and stable isotopes in muscle of fishes from the western Aleutian Islands, Alaska, in relation to islands or locations affected by military occupation. Pacific cod (Gadus macrocephalus), Pacific halibut (Hippoglossus stenolepis), and rock greenling (Hexagrammos lagocephalus) were collected from nearshore waters at contemporary (decommissioned) and historic...

BACKGROUND Exposure to persistent organic pollutants, including polychlorinated biphenyls (PCBs) and organochlorine pesticides, is widespread among the general population. There is evidence of adverse effects on reproduction and early pregnancy in relation to organochlorine exposure but human studies remain limited. The increased use of assisted reproductive technologies (ART) presents unique o...

the levels of 19 organochlorine pesticides (ocps) in surface water and under water sedimentsfrom tanks located nearby the prime agricultural areas of kanyakumari district, tamil nadu, india wereinvestigated to evaluate their pollution risks. a total of 36 surface water samples at 9 sampling sites and27 sediment samples at 9 sampling stations were collected from tanks, which were the water sourc...

organochlorine compounds such as, polychlorinated biphenyls and organochlorine pesticides are among the best known classes of contaminants because of their potential for magnification and harmful biological effects. in this study, the amounts of organochlorine pesticides including d.d.t and its metabolites, α, β and γ-hchs isomers, σcyclodiene (endosulfan, heptachlor, heotachlor epoxide, aldrin...

conclusions in conclusion, toxicological studies showed that, although contamination level in caspian sea fishes was relatively low, the present status might pose a risk about food chain contamination. results the review showed that nine studies were recorded in databases about pesticide residues in caspian sea fish tissues. these studies reported that there is limited evidence of organochlorin...
