CONTACT METHOD OF PHYTOTESTINGTOXICITY OF WASTE FROM CARBONITRATION TECHNOLOGYITEMS WITH FOLLOWING OXIDATION

Abstract

This paper describes the results of laboratory studies by the method of contact phytotestation of waste from the carbonitration of a metal surface with the subsequent deposition of an oxide film. Two test cultures were selected for testing: oats (Avena sativa L.) and radishes (Raphanus sativus). Calculations were made of the germination index of test cultures, toxicity and the level of safe concentration of waste in the soil was determined. After research, conclusions are drawn.
