dc.description.abstract | A species-by-compound matrix of acute toxicity values was studied using principal component analysis. The data matrix contained literature data from 26 aquatic species and 21 chemical compounds. The purpose was to search patterns in the interspecific variation of toxicity. Compounds could be ordered according to their toxicity in an unambiguous way. The ordering explained about 80% of the among-compounds variation in toxicity. The compounds with the highest overall toxicity also had the largest variation in toxicity for different species. The toxicity of non-polar narcotics correlated well with the log Kow. More toxic than predicted by the log Kow were: allylamine, dieldrin, malathion, parathion and salicylaldehyde. The patterns in the sensitivity of the species were less unambiguous. A three components model of the species-by-compounds matrix explained about 56% of the among-species variation in sensitivity. Fishes and amphibians were more sensitive to dieldrin, lindane and pentachlorophenol than the invertebrates. The Phyllopoda (daphnids) were the most sensitive species to aniline, the heavy metals, malathion and parathion. | |
