Contamination of soil with excessive amounts of this precious metal can stem from various sources, including industrial discharge, improper waste disposal practices, and the application of sewage sludge containing silver nanoparticles. Elevated concentrations in the ground pose a threat to the health of ecosystems. For example, high silver levels can negatively impact microbial communities crucial for nutrient cycling and soil fertility. It can also be absorbed by plants, potentially entering the food chain and affecting higher organisms.
Understanding the pathways and consequences of metallic contamination in terrestrial environments is crucial for sustainable land management and the preservation of biodiversity. Historically, silver has been used for its antimicrobial properties, leading to its incorporation in various products and processes. However, the increasing use of silver nanoparticles in consumer goods and industrial applications raises concerns about their potential long-term effects on soil health. Research in this field provides valuable data for developing effective remediation strategies and regulatory guidelines to mitigate the risks associated with this type of contamination.
