“…The hyperaccumulative properties of plants towards Pb have been exploited by scientists and researchers in the phytoremediation efforts towards the control and mitigation of Pb pollution of shooting range soils [23,25,36,44,78]. Phytoremediation strategies have been regarded as green techniques since they do not produce or add any toxins to the environment.…”

“…More studies have been carried out in recent years in order to determine the applicability of phytoremediation as a substitute for the control and management of Pb pollution in shooting range soils [23]. This form of shooting range pollution management strategy has been found to be cost effective and environmentally friendly compared to other techniques such as chemical stabilization and soil removal [83][84][85].…”

“…The cost implications of such methods have also been a topical discussion for sustainable soil remediation and reclamation efforts. In recent years, phytoremediation has become an increasingly cost effective, efficient and environmentally friendly technology for the amendments of highly polluted soils [22,23,36,103]. Phytoremediation describes application of engineered green plants to remove, immobilize, contain and stabilize environmental pollutants such as trace and heavy metals, organic substances and radioactive compounds found in the soil [104,105].…”

“…Over and above, the type of plant is of great influence on the amount of Pb that it can absorb. There are plants that are very effective phytoextractants and phytoaccumulants of heavy metals in the soil and these kinds of plants have been exploited by scientists and researchers in soil reclamation and remediation efforts [22,23]. The control and management of Pb contamination of shooting range soils by plants take place through processes called phytoremediation and phytostabilisation.…”

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.

“…Phytoremediation (via phytostabilization or phytoextraction) is an affordable and environmentally friendly technology for soil remediation and is applicable when metals are located in the rhizosphere [29,30]. However, the in situ phytoremediation of shooting range soils remains poorly documented [31]. Wilde et al (2005) [30] found that the combined use of vetiver grass (Chrysopogon zizanioides) and a fertilizer reduced plant uptake of soil Pb, thus decreasing the associated environmental risks.…”

Soil metal contamination in recreational shooting ranges represents a widespread environmental problem. Lead (Pb) is the primary component of traditional ammunition, followed by metalloids such as antimony (Sb) and arsenic (As). Lead-based bullets and pellets deposited on the soil surface are subject to steady weathering; hence, metal(loid)s are released and accumulated in the underlying soil, with potential adverse consequences for ecosystem function and human health. Amongst the currently available environmentally-safe technologies for the remediation of metal-contaminated soils, chemical immobilization is recognized as the most practical and cost-effective one. This technology often uses inorganic and organic amendments to reduce metal mobility, bioavailability and toxicity (environmental benefits). Likewise, amendments may also promote and speed up the re-establishment of vegetation on metal-affected soils, thus facilitating the conversion of abandoned shooting ranges into public green spaces (social benefit). In line with this, the circular economy paradigm calls for a more sustainable waste management, for instance, by recycling and reusing by-products and wastes in an attempt to reduce the demand for raw materials (economic benefit). The objective of this manuscript is to present a state-of-the-art review of the different industrial and agro-food by-products and wastes used for the remediation of metal-contaminated shooting range soils.
