Abstract: | Surface soil and grass samples were collected from ten locations perpendicular to a major road in Alice and were analyzed for zinc and copper. The results revealed an association between zinc concentration and distance from road traffic. An association was also revealed between soil zinc and grass zinc which suggests same source for the metal in samples. The results for copper did not show any correlation between sample concentration and distance from road traffic. Neither did it show any correlation between soil zinc and soil copper or between grass zinc and grass copper which suggests different sources for the elements. |
