ACUTE TOXICITY TEST OF SOME FOOD ADDITIVES ON AQUATIC SYSTEMS

The occurrence and fate of food additives in the aquatic environment is an emerging issue in environmental chemistry. This paper describes the ecotoxicological effects of the commonly used additives gallates and parabens using the limit test at fish, according to OECD guidelines. There is little available information about the adverse effects of propyl gallate (PG) and parabens on aquatic organisms. Therefore, the toxic effects were compared, using different model systems – acute toxicity test on fish Xiphophorus helleri, bacterium Vibrio fischeri, alga Chlorella vulgaris, cladoceran Daphnia magna, lizozomal function of cell lines PLHC-1 and RTG, and enzymes glucose-6-phosphate-dehidrogenase and succinat dehydrogenase inhibition of cell lines PLHC-1 and RTG - from various trophic levels. It was realized a comparison of PG and parabens with carbofuran. According to the results, PG should be classified as non toxic to aquatic organisms.
