#PlasticPollution in #ShootingRanges and warfare areas - an overlooked #environmental issue
Andrés Rodríguez-Seijo, et al. 15 July 2026
Abstract
"Shooting ranges and military training fields, including warfare-impacted areas, have been widely recognized as environmentally impacted zones by inorganic and organic #contamination, such as #HeavyMetals, polycyclic aromatic hydrocarbons or explosive-related compounds. However, the possible contamination by #plastics and #microplastics in soil has been widely overlooked despite potential plastic sources, such as #ShotgunCartridges, #PlasticWads or #landmines. Due to how these activities occur, plastics have remained in the field for decades or centuries, favoring their conversion from macro to microplastics, polluting the soil and water resources. Moreover, shooting and recreational activities such as #airsoft or #paintball practices could also be a substantial source of plastics to ecosystems; once shot, pellets can have conventional or biodegradable plastics in their composition, and there left in the environment, favouring impacts on soil properties. Although some initiatives have emerged to avoid the use of single-use plastics in shotgun ammunition, alternative materials (biodegradable plastics) can also be a potential risk, favouring the heavy metal bioavailability of shot pellets. These emerging pollutants should also be considered in these areas to understand if they could be a potential source of micro- and nanoplastics to the environment and, therefore, an environmental concern that requires changes at industrial and regulatory levels."Read more:

#Taraxacum #officinale (#Cichorieae) is native to Eurasia; it serves as a #pollensource for numerous insects and also is #indicatorplant for #calcium/#potassium. Its parts are relevant #foodsources. In their studies in Armenia B. Babayan et al. (2025) found concentrations of #heavymetals in the #soil leading to #DNApolymorphisms and thus being well-suited as a #bioindicator for #ecotoxicology.

Though there are many #heavymetals that #coalmining can release to our #freshwater, #selenium has been noted as a particularly risky #pollutant as it bioaccumulates in the #environment reaching toxic levels for #fish, #animals living in riparian areas, and potentially in agricultural #soils and #plants grown in them. This is a risk not only to human #health and the health of aquatic #ecosystems, but also risks the reputation of our regional agricultural products.

Test of 31 #Shein items found 25 (81%) exceeded #EU REACH limits.
High levels of #phthalates (in 18/22 items, up to 70× limit), #PFAS (9/11 items, up to 3,115×), and #HeavyMetals (cadmium up to 126 mg/kg, lead up to 2,110 mg/kg).
Risks: skin contact, ingestion (children), environmental contamination.
Shein says it removes flagged items; @greenpeace calls for stricter enforcement and platform liability.

#GoldExtraction from #EWaste gets 10 times more efficient with new sponge material
Researchers developed a nanoscale cross-dimensional composite material via self-assembly of two-dimensional graphene oxide and one-dimensional chitosan macromolecules.
By Prabhat Ranjan Mishra, Oct 27, 2024
"Researchers have developed a new type of material that’s 10 times more efficient at extracting gold from e-waste than previous adsorbents. Developed by chemists and materials scientists at the National University of Singapore, the material is a type of sponge made of #GrapheneOxide and #chitosan [shrimp shells].
"The material can reportedly transform the way gold is extracted from electronic wastes, which has been described so far as a dirty business with low yields and results in toxic #pollutants.
"The cheaper, cleaner and efficient method was tested by researchers using real e-waste provided by a recycling company."
[...]
"While the present work focused on gold, the team say the technique could be adapted to recover other valuable metals such as #silver, #platinum or #palladium from #ElectronicWaste or even #mining residues. And that is not all: as well as e-waste, the technology might be applied to a wider range of environmental cleaning efforts, such as filtering out #HeavyMetals from #PollutedWater sources or industrial effluents, reported Physics World."
