“…To date, the composition and structure of soil components of the mesofauna soils of Almaty City and the Almaty region remain virtually unstudied. There is minimal research on the impact of soil contamination on the state of ecosystems (Novak 2015;Isayeva 2018;Mustafayev 2015;Karimov et al 2021), which was a reason for choosing this topic and study object. The main purpose of this study was to investigate the effect of heavy metals on the abundance and species diversity of soil mesofauna in urban and background (natural) biocenoses of Almaty City and the Almaty region.…”

Elevated heavy metals in soil are a serious environmental problem that threatens human health and other organisms. Earthworms are widely used as pollution bioindicators of soil ecosystems. The influence of heavy metal content on species composition and population density of earthworms in soils of urban and natural ecosystems has been previously studied. The accumulation of heavy metals in earthworm samples was measured using atomic absorption spectrometry. This study found representatives of 11 species of earthworms in biogeocenoses of the Zailiisky Alatau foothills. The low occurrence of earthworms in ecosystems with a maximum content of cadmium (0.25±0.0024 mg/kg), lead (16±0.70 mg/kg) and arsenic (2.84±0.05 mg/kg) was marked. The number and variety of species of lumbricidofauna differed in urban and natural habitats, indicating that increased heavy metal content substantially impacts earthworms. Earthworms can absorb heavy metals from contaminated soils, which simulates the actions of key elements in the body and causes diseases. Thus, one of the primary determining factors of a positive physical and chemical state of the soil is the number and species composition of earthworms. These data can be used to monitor soil contamination near industrial facilities.
