Application of the phytotesting method to assess the environmental impact of the waste of Lovozersky GOK LLC

Abstract

For a comprehensive assessment of the negative impact of mining waste on environmental objects, the biotesting method was used; phytotesting is a special case of it. The test objects were the tailings of loparite ores, soil and lake water samples in the zone of influence of Lovozero Mining and Processing Plant LLC, located in the Murmansk region. Test cultures - seed oats Avena sativa L., soft wheat Triticum aestivum L., watercress Lepidium sativum. Assessment of the impact of enterprise waste is given on the basis of the joint application of several test cultures and phytotesting methods. A decrease in test functions for a number of objects was found, but no toxic effect was detected. The V hazard class of the tailings of the enrichment of loparite ores stored by the enterprise has been experimentally confirmed, the low probability of overgrowing of the surface of the tailings has been demonstrated.
