The concentrations of several metals in different body tissues of the freshwater snail Lymnaea stagnalis (L.), collected from an uncontaminated environment, were measured by electron probe X‐ray microanalysis. Significant concentrations of the potentially toxic elements manganese, titanium, and copper were detected in all tissues, although they were not detectable in the water sampled at collection; bioaccumulation is thus evidenced. Highest concentrations of manganese and copper were present in the shell, while highest concentrations of titanium were present in the head and foot. Experimental snails were continuously exposed to lead chloride (lead at 5 ppm) for an experimental period of 3 weeks. Both elements were accumulated to different extents by the snail tissues but with high concentrations again in the head of the animals, and chloride also in the visceral hump. No significant alterations in the distribution of the other elements measured were observed in the lead chloride‐exposed animals.
