宁波市晚稻稻米中重金属污染分析及风险评估
Analysis and Risk Assessment on Heavy Metal Contamination in Late Rice of Ningbo City
摘要
Abstract
168 late rice samples, planted in the Ningbo City in 2014, were collected to determine six indicators including inorganic arsenic, mercury, chromium, lead, copper and cadmium contents. The evaluation on heavy metal contamination was conducted accord-ing to integrated contamination index, single contamination index and dietary health risk assessment. The results showed that the rice heavy metal contamination in Ningbo City is generally in a good condition, being at a security level, slightly higher overall contamina-tion level in Xiangshan City and Yuyao City compared with other regions. The single element contamination is at a security level, but the Cd contamination is high, constituting a hidden safety crisis in some counties. Dietary health and safety is generally in a good condition, but Cd and Cr contamination in some samples can be a hazard for dietary health.关键词
