- Abstract
Land snails are often used to monitor soil pollution. The present study aimed to investigate the effects of Weatfert R complex mineral nitrogen, phosphorus, and potassium (N: P: K) fertilizer with high phosphorous content (NPK: 8/36/15 + SO3:13) on Eobania (syn. Helix) vermiculata used as a bioindicator species. Moreover, the histological and biochemical changes in the digestive gland were examined and biomarkers of environmental stress (glutathione peroxidase and lactate dehydrogenase activity) measured. Results showed that the fertilizer tested has a negative impact on the growth rate of juvenile snails. They also revealed alterations in the structure of the digestive gland and changes in biomarker response values in the field, accompanied by significant correlations with bioconcentration. Meanwhile, the biochemical parameters showed varying results representing an increase in the protein rate and a decrease in lipid and carbohydrate rates after treatment with weatfertin. Overall, our study showed that the fertilizer tested could have potential hazards on E. vermiculata and this snail was a suitable sentinel organism and the selected biomarkers are efficient for soil assessment.
