What happens to silver when it enters the environment?
• Silver may be released into the air and water through natural processes such as the weathering of rocks. • Human activities such as the processing of ores, cement manufacture, and the burning of fossil fuel may release silver into the air. • It may be released into water from photographic processing. • Rain may wash silver out of soil into the groundwater. • Silver does not appear to concentrate to a significant extent in aquatic animals.
