为了解铅污染射击场的毒性，将甲螨Platynothrus peltifer暴露于铅含量为47-2398 mg/kg干重（DW）、有机质含量为3.2- 6.8%和3.8- 13%的射击场土壤中。暴露还包括具有不同pH值和OM含量的人工土壤以及用作对照的两种天然土壤。暴露持续2周（急性）和12周（慢性）。螨的生存，繁殖和吸收的铅有关的总，水提取和0.01 M氯化钙提取和孔隙水铅浓度以及土壤特性。在铅浓度≥2153 mg/kg DW和≤ 3.5 mg/kg DW的酸性森林土壤中，急性和慢性暴露对成虫的存活率没有显著影响，而慢性暴露则显著降低了生殖能力。盾叶甲幼螨数量呈显著负相关，螨体内铅浓度与总铅、可提取铅和间隙水铅浓度呈显著正相关。本研究表明，盾叶甲对铅的敏感性不高，因此可能不是铅污染土壤的合适指示物。
To understand the toxicity of Pb-polluted shooting fields, oribatid mites Platynothrus peltifer were exposed to shooting field soils containing 47–2398 mg Pb/kg dry weight (DW) and having 3.2–6.8 and 3.8–13 % organic matter (OM). Exposures also included artificial soils with different pH and OM contents as well as two natural soils used as controls. Exposures lasted for 2 (acute) and 12 weeks (chronic). Survival, reproduction and uptake of Pb in the mites were related to total, water-extractable and 0.01 M CaCl2-extractable and porewater Pb concentrations as well as soil characteristics. After both the acute and chronic exposures, adult survival was not significantly affected, while upon chronic exposure reproduction was remarkably reduced in the acidic forest soils with Pb concentrations ≥2153 mg/kg DW and ≤ 3.5. P. peltifer juvenile numbers were significantly negatively and internal Pb concentrations in the mites were significantly positively related with total, extractable and porewater Pb concentrations. This study shows that P. peltifer is not very sensitive to Pb and therefore may not be a suitable indicator of Pb-polluted soils.
