ABSTRACT

Commissioned and de-commissioned shooting ranges continue to pose an environmental and human health risk due to the accumulation of toxic Pb emanating from spent munitions. The phytotoxic effects of Pb accumulation in plants include inhibition of root growth and lowering of plant metabolism. The uptake of Pb by plants is directly affected by factors such as plant species and physicochemical properties of the soil. However, scientists and researchers have leveraged on the ability of some plant species to accumulate and tolerate Pb toxicity and applied them in the control and management of Pb pollution of shooting range soils. This technique is called phytoremediation. The objectives of this review are: (i) to assess the prevalence of toxic Pb metal in plant species growing in and nearby shooting ranges, (ii) to establish the soil-plant mechanistic pathway for Pb (iii) discuss the effectiveness of phytoremediation technology towards shooting range soil amendment.

摘要

由于废弹药产生的有毒铅的积累，投掷和退役的射击场继续构成环境和人类健康风险。铅在植物中积累的植物毒性作用包括抑制根生长和降低植物代谢。植物对铅的吸收直接受到诸如植物种类和土壤理化特性等因素的影响。但是，科学家和研究人员已经利用某些植物积累和耐受Pb毒性的能力，并将其应用于靶场土壤Pb污染的控制和管理中。这种技术称为植物修复。此次审查的目标是：（i）评估在射击场及其附近生长的植物物种中有毒铅金属的流行程度，
