Improved monitoring of mine remediation: selenium isotopes are a good indicator of cleanup operations
Credit: Canadian Light Source A new testing technique developed using synchrotron light could significantly improve the way we monitor the effectiveness of remediation practices to remove selenium contamination from mining activities. Selenium is a naturally occurring nutrient that humans and animals need in small amounts to maintain good health. However, exposure to higher concentrations can cause neurological problems in humans…
