PESTICIDE POLLUTION OF THE COASTAL WATERS OF THE TAGANROG AND YASENSKI BAYS OF THE AZOV SEA IN 2009-2011

abstract 0811207042 issue 81 pp. 569 – 579 30.09.2012 ru 1248
The residual amounts of the pesticides in the coastal water of the Azov Sea were studied in spring seasons of 2009-2011. The concentrations of the pollutants were determined and the degree of their danger for hydrobionts was assessed. The concentrations of the pesticides diluted in the water of the Taganrog Bay and the eastern Azov Sea are shown to be lower than the maximum admissible concentrations set for fish-ery reservoirs

QuЕChERS SAMPLE PREPARATION IN THE DETERMINATION OF PESTICIDES OF DIFFERENT CHEMICAL CLASSES BY HPLC

abstract 1321708011 issue 132 pp. 117 – 127 31.10.2017 ru 213
The method has been developed of simultaneous determination of active ingredients of different kinds of pesticides in biological tissues (fish liver) by applying HPLC with ultra-violet detection and the rapid method of QuEChERS sample preparation. We defined optimum volume and composition of the reagents for the extraction, time of centrifugation and ultrasound treatment, the origin and composition of sorbents that ensure maximum extraction of the substances studied and further cleanup of interfering substances. Acetonitrile was used as a solvent. The extraction was carried out in the presence of a buffering mixture - trisodium citrate dihydrate and disodium citrate hemihydrate. Bondesil PSA bulk sorbents (alkylated amine containing two amine functional groups - secondary and primary) and C18E (reversed-phase sorbent based on silica gel with grafted octadecylsilane groups were used to purify the extract from coextractable substances (fats, proteins, sugars, organic and fatty acids, pigments and other impurities). The degree of extraction of the analyzed active ingredients of pesticides from the liver of fish was 79%. The detectable pesticide concentrations ranged from 0,4 to 0,97 mg/kg. The relative standard deviation of the analysis results amounted to 0,01-0,14
