Background: In China, Dayu County is famous for tungsten, lead–zinc mines that are abundant in Hezhang County. Cadmium (Cd) is a concomitant pollutant with tungsten and lead–zinc mining. The most severe Cd pollution occurred from the 1970s until 2006. Large-scale mining stopped after 2006 in the two counties; however, the longterm mining led to soil Cd pollution in these areas.
Aim: The study aimed to investigate Cd concentration in crops and dietary exposure among the general population in two Cd-polluted regions. Methods: Local self-seeded grain and vegetable samples were collected and analyzed for Cd content with atomic absorption spectrometry. A three-day dietary interview was carried out among local residents to estimate diet Cd intake.
Results: In total, 957 and 281 crop samples were collected. Three-day diet surveys were conducted among 546 residents a.. View More»
