Determination of the content of heavy metals in soil and insects’ organism of the Moscow region

The content of heavy metals (cadmium, lead, zinc, copper) in the soil and in the body of insects was studied using an inversion volt-amperometric method of analysis (SWV) and spectrometric analysis using ICP 730-ES. Samples for analysis were selected at the Malinki biological station (on the border of the Podolsky and Narofominsky districts of the Moscow region) and at the Pavlovskaya Sloboda agrobiological station (located in the Istrinsky district of the Moscow region). Studies have allowed us to provide an environmental assessment of the composition of the soil and the content of heavy metals in the body of insects. According to the degree of contamination of the organism of insects of the Chrysomelidae family (leaf beetle) and the Carabidae family (ground beetles), the studied metals can be arranged in a series of zinc > lead > copper > cadmium, which practically coincides with a number of pollution of the studied soils by these metals.
