Abstract
Metallic elements in hair were assessed in human subjects randomly sampled from six villages in Hubei province, PR China, known to differ in industrial pollution. Metallic elements assessed included copper, zinc, lead, and cadmium. Subjects sampled included adults and children of both sexes. Soil and rice samples from the villages were also examined for contents of metallic elements.Soil and rice contents of copper, lead, and cadmium were higher in the villages closer to the pollution source (copper smeltery). Hair contents of copper, lead, and cadmium were higher in subjects from the polluted villages compared with subjects from the nonpolluted areas. No differences were found in hair zinc content among the villagers. Cadmium contents in rice and human hair were linearly correlated. For lead and copper a logarithmic relation was found.No difference was found between the two genders with respect to hair metallic contents. With regard to age, hair cadmium content was highest in the older age groups in the polluted villages and may reflect chronic exposure. No other systematic age effects were observed.It was concluded that contents of cadmium, lead, and copper in human hair do reflect the degree of environmental pollution.
