“镉大米”事件曾引发社会广泛关注,为我们敲响了土壤污染的警钟。近期,环境保护部和国土资源部又联合发布了2005~2013年全国土壤污染状况调查公报。结果显示,在实际调查面积630万平方公里中,全国土壤环境状况总体不容乐观,部分地区土壤污染较重,全国土壤总超标率16.1%,土壤污染已成为我国许多地方的“公害”。在土壤污染严重的形势下,相关土肥专家建议,可以通过农艺手段如增加土壤有机质、施用土壤调理剂、采用生物吸收法等能够钝化、减轻甚至修复大多数的超标土壤。加之,近年来,我国微
Cadmium Rice incident has aroused widespread concern in the community, sounded the alarm for soil pollution. Recently, the Ministry of Environmental Protection and Ministry of Land and Resources jointly issued a survey bulletin on soil pollution in China from 2005 to 2013. The results showed that among the 6.3 million square kilometers surveyed in China, the overall soil environmental conditions in the country were not optimistic. In some areas, soil pollution was heavier and the total soil over-standard rate was 16.1%. Soil pollution had become “public hazard” in many parts of China. In the case of serious soil pollution, soil fertilizers experts suggest that most of the excessive soil can be passivated, mitigated and even repaired by means of agronomic techniques such as increasing soil organic matter, applying soil conditioners and using bioabsorption methods. In addition, in recent years, our country micro
