Urinary arsenic research focuses on studying the levels of arsenic present in urine samples as a marker of exposure to this toxic element. Arsenic is a naturally occurring metalloid that can contaminate drinking water and food sources, leading to health issues such as cancer, cardiovascular diseases, and neurological disorders. By analyzing urinary arsenic levels, researchers can assess the extent of exposure and potential health risks in populations exposed to arsenic contamination. This research also aims to develop strategies for detecting and mitigating arsenic exposure to protect public health.
