The results showed that the highest average contents of lead from water spinach(Ipomoeaaquatics)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 veg-etables from these bases in Guangdong Province were at the excellent level. |
