N2 - Most research on polycyclic aromatic hydrocarbons (PAHs) has been focused on homocyclic compounds. However, two-thirds of the aromatic compounds known are heterocyclic, having in-ring substitutions of oxygen, sulphur, and/or nitrogen. PANHs are such a group of heterocycles, containing nitrogen atoms. This makes them better soluble in water than their homocyclic analogues, and consequently perhaps also more bioavailable. Although partly of natural origin, the majority of the PANHs found in the environment originates from anthropogenic sources, for instance, combustion of fossil fuels, or wood preserving industry. Their presence has been shown in air, groundwater, and in both marine and freshwater environments. The aim of this study was found the toxicity rate of various PANHs to soil invertebrates and also the comparison of the sensitivity of the springtail Folsomia candida and the enchytraeid Enchytraeus crypticus to toxicity of these compounds. Both species have been tested under very similar test conditions in OECD artificial soil. Toxicity of four PANHs, acridine, quinoline, phenazine and 1,10-phenanthroline, were tested. Test concentrations of PANHs proceeded from 50mg/kg to 3000mg/kg and NOEC, LC50 and EC50 estimation were evaluated. Both species were influenced by all test compounds. Quinoline was the most toxic of all tested PANHs. Folsomia candida and Enchytraeus crypticus have same sensitivity to test compounds approximately.
