Maddock Multidisciplinaria (Ciencias Naturales y Exactas) heavy metals copper mining environmental risk water contamination The Camaquã Copper Mines (CCM) were the main sulphide deposit in Southern Brazil and have been inoperation from last century to 1996. To evaluate water contamination and environmental risk increase byheavy metals from mining operations, two points on the João Dias Creek were sampled (Station 1, backgroundarea and Station 2, contaminated area). Mining activity increased the natural weakly heavy metal fluxes byapproximately 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 byCu > Zn > Mn whereas Cd, As and Pb fluxes were negligible. The potential human health hazards andrisk assessment related to daily intake of water from João Dias Creek are mostly due to Mn and should beof concern for the contaminated area. The ingestion of water from station 2 represents incremental risksof 130% and 59% respectively, considering the non-carcinogenic and the carcinogenic effects. The realincrease of human health hazards may be greater than those related to the total concentrations since Mn andAs dissolved concentrations were 5.5 and 2.0 higher than acceptable, respectively. 2001 artículo científico 0001-3765 https://www.redalyc.org/articulo.oa?id=32773211 en http://www.redalyc.org/revista.oa?id=327 Anais da Academia Brasileira de Ciências application/pdf Academia Brasileira de Ciências Anais da Academia Brasileira de Ciências (Brasil) Num.2 Vol.73 |
