| Summary: | Under modern conditions of agricultural production, soil pollution with heavy metals (HM) and pesticides is a pressing issue, including for Armenia. Biotesting of the potential mutagenicity level of soil samples from three agricultural land plots in the coastal areas of the Lake Sevan basin was conducted in the spring-autumn period, taking into account the content of HM and pesticides in them. To determine the genetic effects in soil samples, the micronucleus test (Trad-MN) of the model test object Tradescantia (clone 02) was used. According to the main test criteria of the Trad-MN test (frequencies of tetrads with MN and frequencies of MN in tetrads), the maximum level of the studied indicators was established in soil samples of the Lichk region in all time periods of observation, where their values were 2.5-3.5 times higher, respectively. A reliable positive correlation was shown between the frequency of both test criteria and the concentration of As (p<0.01; p<0.001) in the studied soil samples. |
