| Abstract: | Fifty-one pairs of hulled rice samples and the soil from which each rice sample was grown were analyzed for heavy metals in
August, 1979, in order to estimate the background contamination of cadmium (Cd), copper (Cu), and zinc (Zn) in rice grown
in the Houston, Texas area. Both samples were divided into three groups by soil types and colors. The cadmium concentration
in Texas rice was only one-half to one-quarter lower than that of Asian rice. However, the levels of Cu and Zn in rice in
Texas were similar to those reported. Soil heavy metals were lower than ever reported, but these values were consistent with
the geochemical characteristics of the Texas Houston area. No particular relationship was found between the three metals in
rice and the metals in soil where the sampled rice was grown. |
