Result of the non-parametric Kruskal-Wallis statistical analysis. H value shows the discrepancies between the rank sums of BSS from one treatment with the control; higher means more significant. High PM2.5, pH 5, and aluminum shows significant change in the snails’ behavior (p < 0.05).

Test Substances	H	p-value
PM2.5 High	6.859	<0.01
PM2.5 Low	0.118	0.73
Aluminum Nitrate	14.911	<0.01
Lead(II) Acetate	0.134	0.71
Sulphuric acid (pH 5)	6.463	<0.05
Zinc Sulphate	0.032	0.86
