摘要

The current work investigates the role of neutral red retention assay, malondialdehyde contents and DNA damage through comet assay as biomarkers of terrestrial environmental pollution using the land snail Eobania vermiculata. Snails were collected in May near a lignite power station located about 6 km near the city of Ptolemaida in the district of Kozani. The results of the study showed significantly lower neutral red retention times, higher malondialdehyde contents and higher formation of single-stranded DNA fragments in the haemolymph of snails collected from the polluted area compared to control animals. In support of our data, the values of pollution biomarkers showed significant correlations, thus encouraging their use in terrestrial pollution biomonitoring studies and highlighting the effects of pollution in terrestrial environments. The findings of this study indicate that the harmful biological effects previously observed in remain evident even after several years. The research was carried out during a pivotal transitional phase, as the area shifts away from lignite-based activities, providing a valuable chance to reassess ecological baselines.
