Carbonate-rich mining tailings in Lavrion: risk assessment and proposed rehabilitation schemes

Solubility of pyromorphite Pb5(PO4)3Cl–mimetite Pb5(AsO4)3Cl solid solution series

“…This method is based on the principle that aqueous phosphates added to the soil pore solutions form the environmentally stable mineral, pyromorphite Pb 5 (PO 4 ) 3 Cl. Furthermore, mimetite Pb 5 (AsO 4 ) 3 Cl, an arsenate equivalent of pyromorphite in Pb-apatite groups, can potentially play the same role in sites contaminated with As(V) (Comba, 1987;Twidwell et al, 1994;Shi and Erickson, 2001;Magalhães, 2002;Magalhães and Sliva, 2003;Xenidis et al, 2003;Raicevic et al, 2005;Moutsatsou et al, 2006;Bajda et al, 2007;Cabala and Teper, 2007). Pyromorphite and mimetite are the most stable Pb(II) and As(V) forms in the environment.…”

Evaluation of groundwater quality in and around Peenya industrial area of Bangalore, South India using GIS techniques

“…Thus, the need for better management of the quality of water is greatly recognized. The use of maps is common practice in earth-related sciences in order to evaluate the evolution of physical phenomena and predict natural variables as well as assess the risk regarding surface and groundwater contamination in waste disposal industrial and other sites (Komnitsas et al 1998;Komnitsas and Modis 2006;Wingle et al 1999;Xenidis et al 2003). Keeping this in view, observations of field study are integrated in GIS for the evaluation of the impact of industrialization on the groundwater quality in Peenya industrial area of Bangalore.…”

Geostatistical risk estimation at waste disposal sites in the presence of hot spots

“…confined or non-confined), type and characteristics of contaminants (e.g. oxidation state, biodegradation rate, mobility and fate in various media) [10][11][12][13][14][15].…”
