Effects of lead pollution against juvenile Achatina achatina fed on contaminated artificial diet.

We investigated juvenile Achatina achatina snails by feeding graded levels of inorganic lead metal contaminated artificial diet in plastic snaileries in the laboratory. Snails were tolerant of all levels of lead contamination with no mortalities. Results indicated significant (p < 0.05) transfer of lead from diet to snail with high positive (r(2) = 0.98) relationship. Our data suggests that decreased feed intake and growth were found at elevated lead levels. Tissue lead accumulations were lower than dose in artificial diet.
