The Soil Mercury (S-Hg) Concentration Assay Kit is primarily used for detecting and quantifying mercury levels in soil samples. It is widely applied in environmental monitoring to assess soil contamination, particularly in areas near industrial sites, mining operations, or agricultural fields where mercury-based pesticides may have been used. The kit helps in evaluating the effectiveness of soil remediation efforts and ensuring compliance with environmental safety standards. It is also utilized in research studies to understand the distribution and impact of mercury in ecosystems, aiding in the development of strategies to mitigate its harmful effects on human health and the environment.
