    Environmental monitoring and recommendations on decreasing the levels of pesticide pollution in Zhytomyr region of Ukraine
    (2020) Kostromin, D.; Strizhak, K.
    Environmental monitoring was conducted of facilities for storage and disposal of banned and unsuitable pesticides. Pesticide content in soil, water and products of agriculture in Zhytomyr region of Ukraine was examined, and accumulation of organochlorine pesticides by freshwater bivalve mollusks was assessed. Storage facilities of Zhytomyr region contain nearly 392.18 t of pesticides in 137 warehouses, of which 11 meet the requirements, 36 are tolerable, and 90 are in poor condition. 39.07 t of pesticides are kept in containers of good quality, 22.43 t are kept in tolerable containers, and storage containers of other pesticides are of poor quality. In 2018−2019, pesticide content (dichlorodiphenyltrichloroethane (DDT), heptachlor, dichlorodiphenyldichloroethylene (DDE), dichlorodiphenyldichloroethane (DDD), hexachlorocyclohexane (HCH)) was studied in soil and sediments in Zhytomyr region. The content ranged from 0.0007 to 0.07 mg/kg, which is lower than MPC (0.1 mg/kg). The content of HCH, DDT, DDE, DDD and heptachlor was at 0.0007−0.01 mg/dm3 levels in water bodies of Zhytomyr region in 2018-2019, also lower than MPC. In a number of samples of soil, water and vegetables, the recorded levels of DDT and organophosphate pesticides Dragon, Dorpan, and Dursban exceeded MPC in 1.5–3.0 times. Traces of organochlorine pesticide Aldrin were found in soft tissues of bivalve mollusks and in the sediments of water bodies they inhabit. Recommendations are proposed to lower the pesticide content in the environment.
