Abstract
VEGETATION near some industrial complexes shows appreciable contamination with cadmium from certain airborne smokes and dusts. Goodman and Roberts1 found concentrations up to 40 p.p.m. Cd in Festuca spp. growing in areas exposed to industrial contamination in a restricted area in South Wales. Samples from areas not subject to such contamination contained only 0.8 p.p.m. We analysed mixed herbage from an area in south-west England up to 3 miles downwind from a (presumed) source of airborn Cd contaminant. Winter herbage contained concentrations up to 40 p.p.m. with an overall annual mean of 10.1 p.p.m.
