WebFeb 1, 2024 · Similar results were found for CSMR and Larson Ratio as well (Table 1). Land cover strongly influenced the observed trends with urban sites having much larger increases in all three parameters than other land use types (Table 1). For example, the median change in chloride concentration at urban sites was equivalent to an 88% increase since 1992. WebJan 1, 2015 · For example an increase of chloride-to-sulfate mass ratio (CSMR) can give rise to a dramatic increase in lead leaching from lead-tin solder coupled to copper (Nguyen et al., 2010;Gregory, 1990 ...
