人造耕地的质量标准
Quality standard of ACL
    按照我国农田污泥中污染物控制标准﹙ GB484-84 ﹚,对重金属及化合物的最高允许含量,都有明确的规定。例如:汞及其化合物﹙以 H ɡ 计﹚,对于酸性土壤是 5 毫克/千克,对于中性土壤和碱性土壤是 20 毫克/千克。其它的重金属,如镉、铬、砷、铅和硼、矿物油、苯并﹙ α ﹚芘、铜及化合物、锌及化合物、镍及化合物等都有明确的规定。又按照我国城市垃圾农田控制标准﹙ GB8172-87 ﹚,对杂物、粒度、蛔虫卵死亡率、粪大肠杆菌值、总汞、总镉、总铅、总铬、砷、有机质、全氮、全磷、全钾、 pH 、水分等都有明确的规定,在此就不一一列举。
    由于人造土壤是由工厂生产的产品 , 它是由研究人员按照不同的经营目的设计的,它可以达到任何质量标准的要求,如果有必要,我们可以把重金属和有害物质﹙如农药残留物、有毒化合物、放射性物质﹚的含量降低到几乎为零的水平。
    在此,我可以承诺人造土壤的 3 项硬指标: 1 、重金属含量控制在 1 ppm 以下, 2 、有害物质﹙如农药残留物、有毒化合物、放射性物质﹚的含量降低到几乎为零的水平, 3 、有机质含量控制在 5-1 0 ﹪。

According to the control standards for pollutants in farmland sludge in China (GB484-84), the maximum allowable concentrations of heavy metals and compounds are clearly stipulated. For example, the concentration of mercury and its compounds (based on Hg) is 5 mg/kg for acid soil and 20 mg/kg for neutral soil and alkaline soil. The concentration of other heavy metals, e.g. cadmium, chromium, arsenium, lead and boron, mineral oil, benzopyrene, copper and its compounds, zinc and its compounds, nickel and its compounds, etc. are all clearly defined. According to the control standards for municipal waste for farmland use (GB172-87), the concentration of impurities, particle sizes, mortality of ascarid eggs, the value of fecal coliform bacteria, total mercury, total cadmium, total lead, total chromium, arsenium, organic matter, total nitrogen, total phosphor, total potassium, pH, moisture, etc. are all clearly stipulated, which will not be listed here one by one.
Here, I can promise the three inflexible standards of artificial soil, i.e. 1) heavy metal content controlled below 1 ppm; 2) content of hazardous substances (such as pesticide residues, toxic compounds and radioactive materials) reduced to almost zero; and 3) the content of organic matter controlled at 5%-10%.
