Shooting ranges continue to pose environmental and human health risk due to the accumulation of toxic Pb emanating from munitions. Remediation of Pb pollution at shooting ranges has been carried out through application of various techniques of which chemical stabilization is the most common. In some instances, field chemical stabilization has achieved Pb decontamination of the soils to concentrations below the maximum contaminant limits as set by the United States Environmental Protection Agency (USEPA) and World Health Organization (WHO). However, the effectiveness of chemical additives to Pb stabilization depends to a great extent on the physicochemical properties of the soils. This review aims to: (i) discuss the effectiveness of chemical stabilization towards Pb remediation of polluted shooting range soils, (ii) establish the chemical reactions that take place between Pb and the chemical amendment and (iii) understand the influence of the soil physicochemical properties on the effectiveness of the chemical amendment.

对应用于靶场的Pb影响土壤的化学修复技术的机械途径的关键评估–综述

由于弹药产生的有毒铅积累,射击场继续构成环境和人类健康风险。通过应用各种最稳定化学稳定的技术来修复靶场范围内的铅污染。在某些情况下,现场化学稳定作用已使土壤中的Pb净化达到低于美国环境保护局(USEPA)和世界卫生组织(WHO)设定的最大污染物限值的浓度。但是,化学添加剂对Pb稳定的有效性在很大程度上取决于土壤的物理化学性质。这项审查旨在:(i)讨论化学稳定剂对污染的靶场土壤中Pb修复的有效性,
