The levels and distribution of organochlorine pesticides (OCPs) in sediments from the Haihe River, China.
The levels and distribution patterns of the selected organochlorine pesticides (OCPs=p,p'-DDT, o,p'-DDT, p,p'-DDE, p,p'-DDD, alpha-, beta-, gamma- and delta-HCH) in surficial sediments from the Haihe River and Dagu Drainage River of Tianjin were investigated by means of gas chromatography coupled with micro-electronic capture detector (GC-microECD). Concentrations of OCPs in the sediments from ...
متن کاملThe Gravel Packing Chacteristics of Ethiope River Sediments, Southern Nigeria
Submitted: Jul 12, 2013; Accepted: Aug 26, 2013; Published: Aug 29, 2013 Abstract: Sand production in water, oil and gas wells is usually controlled by gravel packing techniques worldwide. Consideration in the gravel pack design requires that the particle size is five or six times the formation sand depending on the formation sand median diameter. Sieve analysis result shows that the grain size...
متن کاملOrganochlorine pesticides in water, sediment, and fish of Paranoá Lake of Brasilia, Brazil.
Paranoá Lake is a man-made reservoir, created in 1959 with the city of Brasilia, the capital of Brazil. The lake has a surface area of 38 Km 2 and an watershed area of 1046 Km, of which approximately 8% is agricultural. Around 450,000 people live in the catchment area. Contamination of Paranoá Lake and other water systems with organochlorine (OC) insecticides has been reported (Dianese et al., ...
متن کاملConcentrations of organochlorine pesticides (OCPs) in human blood plasma from Hong Kong: markers of exposure and sources from fish.
Previous studies revealed that food, particularly fish products, is the major source for human exposure to organochlorine pesticides (OCPs). Our previous studies revealed that contamination of Hong Kong market fish with DDT was 0.74-131 with a mean of 12.2 ng g(-1), ww, a result suggested that local people might be exposed to hazardous concentrations of OCPs. Therefore, the present systematic s...
متن کاملThe Organochlorine Pesticides Residue Levels in Karun River Water
BACKGROUND The organochlorine pesticides (OCPs) are among the most commonly used in water streams around the world. Most of these contaminants are highly hydrophobic and persist in sediments of rivers and lakes. Studies have suggested that OCPs may affect the normal function of the human and wildlife endocrine systems. OBJECTIVES The aim of this study is to determine the concentrations of sel...
