Mercury and suspended sediment loadings in the lower Minnesota River
Article Abstract:
A study of pollution in the Lower Minnesota River reveals that efforts in controling mercury loadings should be concentrated on controlling sediment loadings. The study of the total suspended sediment (TSS) and mercury concentrations in the Lower Minnesota River reveals that amounts remained low during winter, peaked during spring and remained relatively high in summer and fall. Mercury measurements were taken from both point and diffuse sources and were correlated with TSS concentrations. Point source mercury loadings account for only 1% and the remaining 99% comes from atmospheric precipitate.

Photoreduction of mercuric salt solutions at high pH
Article Abstract:
The titanium dioxide (TiO2) assisted photoreduction process appears to be an effective means to remediate mercuric waste below the 200 ppb mercury disposal limit set by the Environmental Protection Agency. A substantial reduction in the concentration of mercury was achieved through TiO2-assisted photoreduction process at high pH. Both the mercury removed from the solution and the TiO2 catalyst could be recycled.
