New method for benzo[a] pyrene analysis in plant material using subcritical water extraction
Sushkova, Svetlana N.; Vasilyeva, Galina K.; Minkina, Tatjana M.; Mandzhieva, Saglara S.; Tjurina, Irina G.; Kolesnikov, Sergei I.; Askin, Tayfun (Elsevier Science Bv, 2014)A new method for benzo[a] pyrene (BaP) analyses in plant material was developed using subcritical water extraction followed by HPLC analyses of the extracts. BaP extraction efficiency was determined by spiking grass ... -
Soil Basal Respiration and Dehydrogenase Activity of Aggregates: A Study in A Toposequence of Pasture Soils
Askin, Tayfun; Kizilkaya, Ridvan (Lithuanian Inst Agriculture, 2009)The objective of this study was to determine changes in soil basal respiration (BR) and dehydrogenase activity (DHA) in soil aggregates along a pasture slope. Soil samples from 0-50 mm depth were taken from three landscape ...
