Abstract: | We detected lead and cadmium in 1 465 vegetable samples of 18 vegetable species collected from 516 vegetable planting bases in Guangdong Province. The results showed that the highest average contents of lead from water spinach(Ipomoea aquatics)was 0.11 mg·kg^-1 in all species of vegetable samples. The highest average contents of cadmium from water cress(Nasturtium officinale R.Br.)was 0.060 mg·kg^-1 in all species of vegetable samples. The qualified rate of lead in all samples was 97.0%. The qualified rate of cadmium in all samples was 98.9%.The average pollution indexes of lead and cadmium in these species of vegetable were less than 0.7. The heavy metal security status of all vegetables from these bases in Guangdong Province were at the excellent level. |
