TLDR
In this paper, a Minie ball recovered in 2016 in an excavation at the site of La Trinidad, in Sarapiqui, belonging to the Museo Historico Cultural Juan Santamaria, was analyzed using optical microscopy, scanning electron microscopy and elemental analysis by energy dispersive X-rays.Abstract:
This study aims to generate a multidisciplinary understanding about the complexity of the historical battle in La Trinidad de Sarapiqui de La Campana Nacional of 1856-1857, particularly in establishing a baseline diagnosis of the macrostructure, microstructure and elemental chemical analysis of a Minie bullet recovered from this historical event. We therefore carried out the first pilot study of a Minie ball recovered in 2016 in an excavation at the site of La Trinidad, in Sarapiqui, belonging to the Museo Historico Cultural Juan Santamaria. In order to obtain information on both its internal and external structure, the techniques of optical microscopy, scanning electron microscopy and elemental analysis by energy dispersive X-rays were used to determine areas of interest in the bullet and also to specify the composition of the white patina which contains primarily three types of elements: Pb, C and O. Here, we identify the possible presence of cerussite crystals in the lead carbonate surface coating in a 165-year-old Minie bullet. It should be noted that knowing the rifle of origin and its bullet is evidence of great importance to contribute to the reconstruction of the historical context in which this event took place and will therefore allow us to establish which artifacts were being used at the time, both by national and Central American adversaries.read more

Fate of heavy metals in a strongly acidic shooting‐range soil: small‐scale metal distribution and its relation to preferential water flow
TL;DR: In this article, the authors investigated the spatial distribution of the metals and their relation to preferential water flow paths in a highly contaminated shooting range soil (Losone, Ticino, Switzerland).

Characterization of Lead in Soils of a Rifle/Pistol Shooting Range in Central Florida, USA
TL;DR: The distribution of lead in soil samples collected from both surface and profile (O 0 to 10 cm) at a 14-year old rifle/pistol shooting range located in central Florida were determined using EPA Method 3051a (microwave, HNO3/HCl=3:1, v/v) as discussed by the authors.

Effect of soil type on distribution and bioaccessibility of metal contaminants in shooting range soils.
TL;DR: Shooting ranges from Department of Defence sites around Australia were investigated for extent of metal contamination, with acidic Townsville soil having the highest proportion of water extractable Pb at 10%, compared to the alkaline Murray Bridge with only 2% PbWater extractable.

Control of lead solubility in soil contaminated with lead shot: effect of soil pH.
TL;DR: Modelling of soil solid-solution phase distribution of Pb suggested that, at least during the 24 months of the study, soil solution Pb concentrations were more likely to be controlled by sorption of P b by the soil solid phase.
