PESTICIDE RESIDUES DETERMINATION IN VEGETABLES FROM ROMANIA BY GC-ECD

摘要

Pesticide use raises a number of environmental concerns. Over 98% of sprayed insecticides and 95% of herbicides reach a destination other than their target species, including non-target species, air, water, bottom sediments and food. Pesticide drift occurs when pesticides suspended in the air as particles are carried by wind to other areas, potentially contaminating them. In this study the organochlorine pesticides have been measured in vegetables samples from Dobrogea county, Romania, by gas chromatography with electron capture detector (GC-ECD) after extraction and clean-up step and also the calculated bioconcentration factor (BCFs values) were used to relate pesticide residues in plants to the pollutant concentration in soils. The pesticides concentrations were at ppb levels and BCFs values were below 1.
