Features of biotesting rice soils for the purpose of their ecotoxicological assessment

Abstract

Biotesting is a method of integral environmental assessment. In biotesting, toxicological analysis is carried out using approved methods, taking into account the total effect, regardless of the qualitative and quantitative characteristics of the tested environment. Biotesting is applicable for assessing the quality of natural and waste water, soil. Representativeness of the data obtained by biotesting depends on the selected test-objects, their quantity and use of the approved methodology. Problems of toxicological assessment of contaminated soils and selection of biotesting techniques are considered. A set of biotests is proposed, the use of which gives a reliable characteristic of ecotoxicological state of soil.
