Bisphenol A (BPA) presents a serious threat to soil ecosystems, yet its effects on soil-inhabiting organ-isms are mostly unexplored. Therefore, the impact of environmentally relevant BPA concentrations ona terrestrial model organism, the earthworm Eisenia fetida, was assessed. Animals were cutaneously exposed to 100 nM and 10 uM BPA up to 10 days (10-d). Next, a battery of biomarkers was used forecotoxicological evaluation on a cellular, tissue and behavioural level. HPLC analysis showed that aftera 10-d exposure, BPA accumulation reached a maximum of 2.50 ug BPA per g of wet tissue weight. Onthe cellular level, up to 3-d BPA exposure caused increased lipid oxidation indicating oxidative stress. Histopathological assessment of cell wall and ovaries after 7- and 10-d BPA exposure showed multipleabnormalities, i.e. hyperplasia of epidermis, increased body wall thickness and ovarian atrophy. Detec-tion of these changes was facilitated by a newly proposed semi-quantitative scoring system. Finally, behavioural changes were detected after only 3 days of exposure to 100 nM BPA. Altogether, the presented multilevel toxicity evaluation indicates high sensitivity of earthworms to low BPA doses.
