Abstract
This study examines the effects of two road salts, sodium chloride (NaCl) and calcium magnesium acetate (CMA), on the health of two earthworm species: Eisenia fetida and Lumbricus terrestris. Over a 4-week period, approximately 168 earthworms were exposed to varying concentrations of either NaCl, CMA, or mixed ratios of both, with a control group included for comparison. The experiment involved monitoring the changes in earthworm weight and measuring their contraction rates to determine physiological responses. Statistical analysis revealed no significant differences in weight or activity between NaCl and CMA treatments for either species. However, higher concentrations of NaCl resulted in significant weight loss for Eisenia fetida. No notable impacts were observed among different NaCl/CMA mix ratios. These findings suggest that CMA does not confer a distinct biological advantage over NaCl for earthworm health, though its higher cost may be offset by reduced environmental and infrastructure damage. The results highlight the need for further research into alternative road salts and their ecological impacts.
