Water pollution by special waste

Abstract

The environmental impact of special waste was determined using bioindication method. The results show that even small concentrations (1-2%) of shampoos in the water cause total loss of zooplankton and phytoplankton and most of bacterioplankton, indicating the risk of shampoos use. To assess contaminants leaching from waste to water, landfill simulation reactors were used to simulate conditions over several decades. The metals’ weight in the input and output waste was compared. The lowest leaching rate was found for lead, while the highest was found for cadmium and chromium. Besides, it was confirmed that the degree of leaching depends on the humidity and organic matter in the landfill: the higher the organic matter, the more heavy metals are leached from the waste. Besides, the system was developed allowing to control light scattering characteristics for environmental monitoring of natural water-disperse media, measuring of brightness at different observation angles under deep-regime conditions, building spatial scattering indicatrix, which makes it possible to determine the ecological state of the water object and the nature of pollution processes.
