Possible treatments for arsenic removal in Latin American waters for human consumption

Litter, Marta I. and Morgada, Maria E. and Bundschuh, Jochen (2010) Possible treatments for arsenic removal in Latin American waters for human consumption. Environmental Pollution, 158 (5). pp. 1105-1118. ISSN 0269-7491

Abstract

Considering the toxic effects of arsenic, the World Health Organization recommends a maximum concentration of 10 μg L-1 of arsenic in drinking water. Latin American populations present severe health problems due to consumption of waters with high arsenic contents. The physicochemical properties of surface and groundwaters are different from those of other more studied regions of the planet, and the problem is still publicly unknown. Methods for arsenic removal suitable to be applied in Latin American waters are here summarized and commented. Conventional technologies (oxidation, coagulation-coprecipitation, adsorption, reverse osmosis, use of ion exchangers) are described, but emphasis is made in emergent decentralized economical methods as the use of inexpensive natural adsorbents, solar light technologies or biological treatments, as essential to palliate the situation in poor, isolated and dispersed populations of Latin American regions.
