Environmental assessment of the impact of iron ore mine emissions on biological indicators of winter wheat

Abstract

The degree and nature of damage to winter wheat in the zone affected by the iron ore mine are studied. Laboratory studies of indicators of the ontogenesis of winter wheat growing at different distances from the ventilation shaft of the iron ore mine as a main source of atmospheric emissions were performed using instrumental measurements. The intensity of plant grain germination was studied using a growth test to investigate the changes in biological characteristics of winter wheat growing at different distances from the ventilation shaft. As a result of the studies of winter wheat ontogeny indicators, changes in biological indicators depending on the distance to the emission source were established. Exponential dependences of changes in linear dimensions, mass indicators, biological yield of winter wheat, and phytotoxic effect for the first generation of plants depending on the distance to the emission source were established, which allows assessing the man-made impact of industrial emissions from an iron ore mine on the productivity of agrocenoses. A comparison of the research results of industrial emissions̕ technogenic impact on the ontogenesis of winter wheat with the consequences of the technogenesis of agrophytocenosis cultures in the first generation gives a satisfactory convergence of about 92%.
