Última Copper Mining and Environmental Costs in Dominica AgEcon Harris-Charles, Emaline L.; Pemberton, Carlisle A.. A proposal from an international mining company to establish a copper mining operation in the Caribbean island of Dominica could be highly favourable, given the potential for financial benefits associated with such a project. On the downside, such projects are often associated with environmental damage. The area targeted for this copper mine was a rainforest in the north-eastern portion of Dominica occupying around 12 percent of the island’s total land area. A critical question is therefore whether copper mining could be a viable alternative to agrarian uses of the targeted area, if both financial and environmental costs are taken into consideration. A Contingent Valuation Survey of Dominicans and Visitors allowed for inclusion of non-market costs...

Ano: 2007 URL: http://purl.umn.edu/36803 Environmental risk increase due to heavy metal contamination caused by a copper mining activity in Southern Brazil Anais da ABC (AABC) BIDONE,EDISON D.; LAYBAUER,LUCIANO; CASTILHOS,ZULEICA C.; MADDOCK,JOHN L.. The Camaquã Copper Mines (CCM) were the main sulphide deposit in Southern Brazil and have been in operation from last century to 1996. To evaluate water contamination and environmental risk increase by heavy metals from mining operations, two points on the João Dias Creek were sampled (Station 1, background area and Station 2, contaminated area). Mining activity increased the natural weakly heavy metal fluxes by approximately 5424 kg. ( ~ 60%) of the total metal flux, 1542 kg. ( ~ 49%) of dissolved and 3881 kg ( ~ 66%) of particulate metal flux. Total metal flux of anthropic origin was mostly due to Fe followed by Cu > Zn > Mn whereas Cd, As and Pb fluxes were negligible. The potential human health hazards and risk assessment related to daily intake...
