Lankton, J.S., 2018, Histopathological assessment of the digestive gland of a freshwater snail (Lymnaea stagnalis) exposed to uranium: U.S. Geological Survey data release,


This dataset consists of measurements of the digestive gland in the freshwater snail Lymnaea stagnalis orally exposed to uranium. The objective of the study was to assess the morphological effects of uranium on the snail digestive gland by light microscopy. Laboratory-cultured L stagnalis were exposed to either synthetic or natural solid phases of uranium and a subset (6 controls and 6 exposed) were euthanized and fixed in 10% neutral buffered formalin for histopathological assessment. Slides were processed and stained with hematoxalin and eosin as per standard procedure (Luna 1968). The size of each sample, the length and width of digestive gland tubules (5 random glands per sample) and height of digestive cells (10 random cells per [...]

Previous studies performed in the Croteau laboratory suggest clinical effects (e.g. decreased feeding behavior) in snails orally exposed to uranium, but to our knowledge, pathological investigation of direct toxicosis has not been performed. This study is the first in a series of studies using histopathology as a technique for morphological assessment of toxicity.
