[Potential for benz(alpha)pyrene uptake from the soil into potato tubers and grain].

A significant correlation between benz(a)pyrene concentration in soil and potato tubers was established for its soil level of 0.6-50.0 mg/kg. This points to potato uptake of the carcinogen even at low levels of pollution. Absence of correlation between benz(a)pyrene concentrations in grain (husk) and soil even for relatively high levels of soil pollution (up to 320 micrograms/kg) shows that wheat and millet grains do not absorb the carcinogen.
