Gold Mining in the Peruvian Amazon: Global Prices, Deforestation
2011419We show that gold price is linked with exponential increases in Peruvian national mercury imports over time (R 2 = 0.93, p = 0.04, 2003–2009). Given the past rates of increase we predict that mercury imports may more than double for 2011 (∼500 t/year). Virtually all of Peru's mercury imports are used in artisanal gold mining.
