为探明江西省烟田常用肥料中重金属的质量安全状况,采集了钙镁磷肥、镁肥、钾肥、硼肥、有机肥、有机-无机复混肥和烟草专用肥样品,通过ICP-MS法分析了样品中As、Cd、Cr、Cu、Hg、Ni、Pb和Zn的含量,并使用内梅罗指数法对其质量进行了评价.结果发现,江西省烟田肥料重金属含量总体处于安全水平,但各类肥料中重金属含量差异较大,钙镁磷肥、有机肥和有机-无机复混肥中重金属含量较高,且钙镁磷肥中Cr和有机-无机复混肥中As存在超标现象;镁肥、钾肥和硼肥中重金属含量较低.方差分析显示,钙镁磷肥中Cr和Ni、有机肥中Cd和Hg、有机-无机复混肥中Zn含量均显著高于其他肥料.

In order to access the quality and safety of tobacco fertilizers commonly used in Jiangxi Province, calcium magnesium phosphate, magnesium fertilizer, potash fertilizer, boric fertilizer, organic fertilizer, organic-inorganic compound fertilizer and special tobacco fertilizer were collected and the contents of As, Cd, Cr, Cu, Hg, Ni, Pb and Zn in these fertilizers were determined by ICP-MS. The Nemerow index method was used to evaluated their quality. The results showed that the contents of heavy metals in tobacco fertilizers of Jiangxi Province were at a safe level, although the variation was large. Heavy metal contents in calcium magnesium phosphate, organic fertilizer and organic-inorganic compound fertilizer were relatively high in general, but Cr content in calcium magnesium phosphate and As content in organic-inorganic compound fertilizer exceeded the limits. The contents of heavy metals in magnesiumfertilizer, potashfertilizer, boric fertilizer, organic fertilizer were low. Analysis of variance revealed that there was significant difference among Cr and Ni concentrations in calcium magnesium phosphate, Cd and Hg concentrations in organic fertilizer, Zn concentrations in organic-inorganic compound fertilizer with other fertilizers.
