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 sylvestrisL.). 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.

Highlights

The modern concept of sustainable development is based on three important constituents: economic, social and environmental
In May 2020, four test sites were laid in the industrial impact zone of the Apatit project: P1 – Tailing Dump, it is located in the southeast direction, 2 km from the center of the Tailing dump of ANOF-2
As a result of the research, it is found that the proportion of fertile pollen of P. sylvestris in the control is 70.2%

Summary

Introduction

The modern concept of sustainable development is based on three important constituents: economic, social and environmental. One of the conditions required to maintain the environmental sustainability of areas with industrial impact is the assessment of the state of the environment. In the Murmansk region, it is based on the mining complex, which includes enterprises of the extractive, metallurgical, mining and chemical industries Most extensively mined are copper-nickel, apatite-nepheline, apatite-magnetite, iron and rare metal ores. The Apatit project is one of the largest producers of phosphate raw materials for the production of mineral fertilizers (the world 3rd largest after China and Morocco) based on the Khibiny deposits of apatite-nepheline ores [1]. Processing of apatite and nepheline concentrates is carried out outside the Murmansk region
