Biomonitoring of the toxic effects of industrial emissions

Abstract

The article presents results of studying the impact of industrial emissions of the Apatit project (Murmansk region) on the fertility and sterility of pollen of Scotch pine (Pinus sylvestris L.). A low share of fertile pollen (49.3–57.4%) and high ratio of sterile pollen (42.6–50.7%) are revealed in the samples from the city of Apatity under study. The study calculated the palynotoxic effect of the industrial emissions. Shown the toxic effect of emissions of the apatite-nepheline complex on male gametophyte of Scotch pine and the process of gamete formation. The ecological safety of the city of Apatity is closely related to the problems of the complex use of apatite-nepheline ores and the minimization of storage of waste in tailing dumps.
