ФИЗИКО-ХИМИЧЕСКИЕ ПРОЦЕССЫ, ПРОИСХОДЯЩИЕ НА ПОВЕРХНОСТИ КВАРЦЕВОГО ПЕСКА ПРИ ВНЕСЕНИИ ЗАГРЯЗНЕНИЯ, И ИХ ВЛИЯНИЕ НА РЕЗУЛЬТАТЫ ФИТОТЕСТИРОВАНИЯ

Abstract

Contamination of sandy soils with liquid hydrocarbons (oil and products of its processing), along with salinization, is a characteristic process developed in vast territories associated with oil production. On the example of model experiments using natural quartz sand, the influence of physic-chemical processes on the growth and development of higher plants during fitotesting is considered. The observed physico-chemical processes occur when liquid hydrocarbon and salt pollution enter the soil. We have shown the multidirectional influence of several combinations of pollutants and their amount on the biological parameters of the test culture of white mustard (Sinapis alba L.). Based on the analysis of theoretical concepts, a possible mechanism for regulating the processes occurring at the phase interface when the used combinations of pollutants enter the studied soil system is described. It is suggested that the main contribution to the development of physic-chemical processes in the investigated sand system will be made by the presence of amorphous silica
