The ultrastructure of the midgut epithelial cells of Tetrodontophora bielanensis (Collembola) fed either with lead-, cadmium- or zinc-enriched food or kept under control conditions was compared by transmission electron microscopy (TEM). Atomic absorption spectrophotometry (AAS) showed accumulation of these three metals in the body tissues of the collembolans. Intracellular localization of zinc in the midgut epithelial cells was investigated by electron spectroscopic imaging (ESI) and electron… CONTINUE READING
