One Century of the Discovery of Arsenicosis in Latin America (1914-2014): As 2014 - Proceedings of the 5th International Congress on Arsenic in the Environment
This study was carried out to evaluate the concentrations of As in soils ("near total" and available fraction), forage plants and horticultural crops in the surrounding area of a Portuguese industrial chemical complex. International regulatory guidelines were used to identify contaminated land (>46% of the sampling sites). The spatial distribution of As in the different study samples indicated a similar anthropogenic pattern, the highest values located near the industrial plants and some old sewage outlets. Forage plants (gramineae) present higher As concentration (0.3 to 255 mg kg-1 dry weight) than the studied crops (cabbage, tomato, maize, lettuce (0.1 to 3.5 mg kg-1 dry weight). Taking into account that some local soils are considered to be contaminated, more data from different environmental medium should be used in the future to investigate possible relations with local health problems. © 2014 Taylor & Francis Group.
