Summary: The laboratory experiments were carried on using the juvenile mollusk Achatina fulica as a bioindicator of soil contamination and air pollution. It is shown that when experimental animals breathed and had dermal contact with the aerosols prepared from the wastewater and those prepared from two solutions of Ni in distilled water at two concentrations they weighed significantly less than controls . According to the results of AAS, heavy metals (HM), in particular Cd, Cu, Ni of sewage accumulated in the digestive gland of the shell. In model experiments mollusks were contained in the chamber periodically (2 hours of input and 2 hours of pause) filled with aerosol containing Ni at concentrations of 30 and 50 mg / dm3 nickel for two weeks It resulted in accumulation of Ni in the digestive gland of mollusks with concentrations 6 to 10 times exceeding controls, respectively. At that the experimental animals gained weight reliably slower than the controls contained in aquatic aerosol without Ni. The subsequent one week exposure of shells in aerosol, prepared from the distilled water without Ni reduced the concentration of nickel in the tissue of the digestive gland. Thus, bioavailability of HM and nickel solutions prepared from untreated wastewaters in breathing aerosol and possibly by skin contact was demonstrated. The toxicant delivery seems to occur apart from food intake.
