Status of Soil Organic Matter and Levels of DDT Residues in Some Agricultural Soils in Albania (Published)
Soil Organic Matter (SOM) plays an important role in sorption of pesticides. If SOM content is high, the pesticide residues, as they are nonpolar, can be bound to particulate SOM, otherwise they present a risk to the flora, fauna and human health. Persistent Organic Pollutants (POPs) are chemical substances that remain in the environment, bioaccumulate through the food chain, and can cause negative effects on the environment and human health. This study was aimed to estimate soil organic matter and persistent organochlorine pesticide residues in some organic and conventional greenhouses/farms in areas of central Albania. Soil organic matter was determined by the gravimetric determination of ignition loss. Analysis of organochlorine pesticide residues were performed by gas chromatography – mass spectrometry. Organic matter contents were in a range of 1.96 % to 5.41 %. The minimum of ƩDDT residues was 0.10 µg/kg and the maximum of ƩDDT residues was 13.33 µg/kg.
