DDT Residues as a Contaminant in Formulated Sevin and Malathion Samples

solid phase extraction of pesticide residues in water samples: ddt and its metabolites

solid phase extraction (spe) cartridge embedded with octadecyl c18 chain bounded to silica particles were used for the isolation and trace enrichment of pesticides from water samples collected from cotton, rice growing and municipal areas. the eluents were analyzed with high performance liquid chromatography (hplc) using methanol (100%) as mobiles phase at different uv-visible wavelengths. ddt ...

Effectiveness of Deposits of Sevin, Ddt, Bayer 39007, and Bayer 37344 against Anopheles Albimanus in Haiti.

DDT residues in water, sediment, domestic and indigenous biota from a currently DDT-sprayed area.

DDT is used for indoor residual spraying (IRS) in Limpopo Province, northern South Africa to control malaria. Through IRS, DDT may reach the outdoor environment via dust and air and from possible spillages during application. In this area the local people consume domestic chickens, wild fish or birds. Fish from the river catchment and impoundments seem to be the major source of protein intake. ...

Pesticide residues in food 2000 : DDT

Decline of DDT residues in migratory songbirds.

Analyses of ten species of migratory songbirds killed when the birds flew into television towers in Florida showed a progressive decline in the concentration of DDT and its metabolites (DDD and DDE) in their fat depots for the period 1964 to 1973. This decline is apparently correlated with the decreased usage of DDT in the United States during the same time.
