Significantly higher amounts of HMs were accumulated in snail hepatopancreas and not in
foot. Cu, Zn, and Cd have biomagnified in the snail body, particularly in the hepatopancreas.
In contrast, Pb decreased when going up into the food chain. Zn, Cd, and Pb correlated highly
with each other at all levels of the investigated food chain. Zn and Pb exhibited an effective
soil–plant transfer, whereas in the snail body only foot Cu concentration was correlated with
that in soil. There were significant differences among sampling sites for WN, SH, and RSH
when compared with reference snails. WN was strongly correlated with Cd and Pb
concentrations in nettle leaves but not with Cu and Zn. SH was independent of HM
concentrations in soil, snail hepatopancreas, and foot. However, SH correlated negatively
with nettle leaves concentrations for each HM except Cu.
