Sites of intracellular metal deposition in the midgut ventriculus and in the proventricular glands of Xenillus tegeocranus (Hermann, 1804) (Acari: Oribatida) were studied by TEM. The study aimed to obtain new information on the ultrastructural features of heavy metal compartmentalisation and elimination mechanisms in oribatid mites. Specimens of X. tegeocranus were collected from an abandoned […]

The fine structure of the midgut and the Malpighian papillae in Campodea (Monocampa) quilisi Silvestri, 1932 (Hexapoda, Diplura) specimens was described. We observed the presence of electron-dense granules (EDGs) in the midgut epithelial cells, similar in genesis, structure and aspect to the type A spherocrystals described in the midgut epithelium of Collembola and Diplopoda. Energy-dispersive […]

Clay pigeon shooting ranges can be an important source of heavy metal contamination in terrestrial ecosystems. The pellets contained in spent ammunition are mainly composed of lead (Pb) and antimony (Sb). Total concentrations of these metals were measured in soils from seven sampling sites within a clay pigeon shooting range and compared with two controls to investigate the […]

Soils in clay pigeon shooting ranges can be seriously contaminated by heavy metals. The pellets contained in ammunition are composed of Pb, Sb, Ni, Zn, Mn and Cu. The total concentrations of these metals in soils, and the effects of their increasing levels on the arthropod community were investigated at seven sampling sites in a […]
