Title: | Arsenic transfer and impacts on snails exposed to stabilized and untreated As-contaminated soils | Authors: | Coeurdassier, Michaël Scheifler, Renaud Mench, Michel Crini, Nadia VANGRONSVELD, Jaco de Vaufleury, Annette |
Issue Date: | 2010 | Publisher: | ELSEVIER SCI LTD | Source: | ENVIRONMENTAL POLLUTION, 158(6). p. 2078-2083 | Abstract: | An As-contaminated soil (Unt) was amended with either iron grit (Z), a coal fly ash (beringite, B) or B + Z (BZ) and placed in lysimeters in 1997. An uncontaminated soil (R) was also studied. In summer and autumn 2003, lettuces were cultivated in the lysimeters and snails were caged for one month. Lettuce As concentrations were higher during the summer, while no differences occurred in snails between seasons. Snail As concentrations (mu g g(-1) DW) ranged from 2.5 to 7.0 in B, Z and BZ, and peaked at 17.5 in Unt. In summer, snail survival was affected in Unt and Z compared to R and B while no mortality was noticed in autumn. Snail growth decreased only in B. BZ and Unt in autumn. Snail As concentrations suggest a risk for their predators even on the remediated soils. (C) 2010 Elsevier Ltd.
