уровни токсичности

The article presents the dependence between results of composition waste and surface water according to physical, chemical and toxicological characteristics. It was found the lack of statistically significant linear de-pendence between the results of bioassay and measurement of physical and chemical composition of the wastewater chemical and petrochemical plants and water bodies of water, which were taken above and below wastewater discharges. For mine water from the drive it was installed a weak correlation between bioassay results and their physi-cal and chemical composition, but the corresponding regression equation proved statistically insignificant, for water of water bodies, which are discharged mine water, it was set the average measurement between the above indicators.

For research of intercommunication between the levels of toxicness and muddiness of water were drawn on the results of measuring of component composition and determination of toxicness of sewages of enterprises of the different industries of economy, located on territory of a few areas of Ukraine. It is shown that in each of cases the set of meaningful physical and chemical indexes which correlate with data of biotesting is different and depends on component composition of sewages. The brought results over are base on the use of far of experimental data and have an important practical value for the exposure of reasons of origin of toxic properties of sewages with the purpose of realization of corresponding nature protection measures on their removal.
