通过硅藻土粉尘的动物致纤维化实验、家兔红细胞溶血实验研究，结果表明硅藻土粉尘的细胞毒性较低，致纤维化作用较弱。通过流行病学调查和现场劳动卫生学调查，利用目前较公认的寿命表法进行粉尘容许浓度的计算，在参考国内外有关资料和国外标准的基础上，提出含游离ＳｉＯ２１０％以下的硅藻土粉尘的卫生标准的建议值为１０ｍｇ／ｍ￣３。
Diatomaceous earth dust caused by animal fibrosis experiments, rabbit erythrocyte hemolysis experimental results show that the diatomite dust cytotoxicity is low, resulting in weak fibrosis. Based on the epidemiological investigation and on-site labor hygiene survey, the current more accepted life table method was used to calculate the allowable dust concentration. Based on the domestic and foreign relevant information and foreign standards, the authors proposed that diatomite containing less than 10% The recommended value for dust hygiene standards is 10 mg / m3.
