Increasing attention has been paid to the toxicity and hazards of antibiotics on non-target organisms in soil ecosystems as excess antibiotics in the excretion of treated animals are being brought into the soil through manure and sewage irrigation.

Abstract The present study utilized a biomarker response method to evaluate the effect of 3,5,6-trichloro-2-pyridinol (TCP) in artificial and natural soils on Eisenia fetida after 7, 14, 28, 42 and 56 days exposure. Biomarker responses were standardized to calculate the Integrated Biomarker Response (IBR) index. The influence of soil type on TCP toxicity was assessed. Results indicated that TCP induced excessive reactive oxygen species, caused oxidative stress, DNA damage to earthworm, which is similar to its parent chemical chlorpyrifos. The IBR index of three enzymes activities showed that TCP induced the enzymes activities of earthworm in red clay was stronger than the other three soils. Specifically, chlorpyrifos exposure group showed a lower toxicity than TCP exposure group after 28 days exposure but a higher toxicity than TCP exposure group after 56 days exposure. Despite the deficiencies of this study, the above information is of great significance for assessing the risk of chlorpyrifos and its metabolite TCP pollution in soil ecosystems.

The performance of a biological treatment of a PAH-contaminated soil was evaluated with respect to its physicochemical and ecotoxicological properties. After six months, the biological treatment led to an significant reduction of 2- and 3-ring PAHs and to a lesser extent to 4-ring PAHs. As a consequence a significant decrease of the acute ecotoxicity was observed passing from highly ecotoxic before treatment to non-ecotoxic according to Lactuca sativa seedling and growth inhibition test and Eisenia fetida mortality test. This could be related to the bioavailability of PAHs. Indeed, tests performed on aqueous leachates of the soil showed a strong decrease of 2- and 3-ring PAHs correlated with a significant reduction of acute and chronic ecotoxicity responses. The biological treatment led to the mutagenicity reduction and the genotoxicity disappearance in the leachate. Thus, bioassays are complementary to chemical analyses to evaluate the efficiency of a bioremediation process and to evaluate the bioavailability of the organic pollutants as the total concentration of a contaminant is not the only criterion to consider. The comparison of the ecotoxic responses allowed us to underline the best sensitivity of the earthworm, Microtox, Alga and Ames bioassays among the tested set. These bioassays could thus be good candidates to build a toxicity evaluation procedure for PAHs contaminated/ remediated soils.
