Abstract
In this article, the distribution of heavy metals contained in residual water to the environment is explained as follows: when the city's wastewater is discharged to treatment facilities, it is first cleared of large impurities, and then of sand. After treatment of waste water from vineyards and fat mixtures in settling tanks are filtered on specially designated land plots. Currently, the most urgent problem is the implementation of a method of bioassay, characterized by a reduction and rapid implementation of the impact of toxic substances on the hydrobionts of water sources. This article is intended to study the toxic effect of ingredients contained in waste waters of Kentau by the method of bioassay and sorption of water from a mixture of heavy metals.
