| 中文摘要: |
| 通过对来源于广东省516个蔬菜种植基地18种蔬菜品种1 465个样品中铅、镉含量的检测分析,结果表明:蕹菜品种铅平均含量最高(0.11mg·kg-1),西洋菜镉平均含量最高(0.060mg·kg-1);总样品铅检测合格率97.0%,镉检测合格率98.9%;所检蔬菜品种的铅、镉平均污染指数均小于0.7。表明广东省各生产基地的蔬菜重金属安全状况总体较好,处于优良水平。 |
| 英文摘要: |
| 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(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. |
