METHOD FOR BIOLOGICAL ASSESSMENT OF TOXICITY LEVEL OF MARINE ENVIRONMENT Russian patent published in 2015 - IPC G01N33/18 G01N25/44 

FIELD: ecology.

SUBSTANCE: method for biological assessment of the toxicity level of the marine environment refers to biological methods for assessing an environmental risk and analysing the marine environmental pollution, and can be used in marine culture, aquatic toxicology, and fish farming. As biological test objects, the method uses larval Black Sea silversides (Atherina hepsetus, Atherina mochon pontica), which are placed into the test environment and sterile seawater. The reference is the test environment and sterile seawater free from any toxic agents. That is followed by microcalorimetric measurements of larval head production, and the derived specific heat production, as well as its decrease in the test objects exposed to the action of toxic agent as related to the values of intact larvae, the toxicity level of the marine environment is stated. The method differs by high sensitivity and enables the reliable assessment of the marine environment at the low concentration of the toxic agents.

EFFECT: that enables performing the early diagnosis of the toxicity level of the water environment.
