The paper presents the complex environmental estimate of the polyurethane protective coatings, modified by tetraethoxysilane and contained a galvanic sludge as a filler of galvanic waste. The study of the emission of heavy metal ions from the polymer coating designed to model the aquatic environment was conducted by the methods of physicochemical analysis. The samples of the polymer protective coatings with lower toxicity were defined by different methods of bioassay. It is recommended to use the methods of bioassay while developing of the samples of polymer as the most sensitive, express and do not require large financial costs methods. Electroplating sludge`s usage as a filler in polymer protective coatings helps address the problem of resource saving, recycling of industrial waste and environmental protection.
