Cuyuna manganese focus area fildnrstatemnus6 Potential Environmental Effects of Uranium Mining

Manganese grades greater than 50 are observed in core from the northern portion of the Emily District with reserve estimates that would make this area one of the largest undeveloped manganese deposits in North America A company called Cooperative Minerals Resources has been actively exploring options for developing a manganese resource in• Significant potential environmental risks are associated with extreme natural events and failures in management practic Extreme natural events eg hurricanes earthquakes intense rainfall events drought have the potential to lead to the release of contaminants if facilities are not designed and constructed to withstand such events or fail to perform as designed

Cooperative catabolic pathways within an atrazine Soil organic matter attenuates the efficacy of flavonoid

The enrichment culture was destabilized by loss of Nocardia sp when grown on ethylamine ethylammelide and cyanuric acid after which the consortium was no longer able to degrade atrazine The analysis of this enrichment culture highlights the broad level bacterial community interactions that may be involved in atrazine degradation in natureManganese dioxide experiments To test for the possibility of a flavonoid and DOC oxidation reaction catalyzed by metals naringenin 06 mM was incubated with MnO 2 1 mg in the presence or absence of catechin 06 mM for 24 hours at 30 176 C in 1 ml of phosphate buffer at pH 7
