摘要
Aqueous film-forming foams (AFFF) are used to extinguish hydrocarbon fuel fires. Certain AFFF products such as 3M Lightwater contain perfluorooctane sulfonate (PFOS) as the active ingredient which is highly persistent in the environment and is thus globally prevalent. With thousands of tons of soils potentially contaminated with PFOS stockpiled at a number of sites in Australia, the lack of reliable information on bioavailability of this recalcitrant contaminant constrains the application of a risk-based strategy for managing such soils. In this study, the PFOS release pattern from soils collected from the contaminated sites of fire training areas and its bioaccumulation potential in earthworm were investigated. The study was conducted at two temperatures (25 and 37 degrees C) and 60 % of the maximum water-holding capacity of soils. The greatest release into water was found to occur from the soil having the highest PFOS concentration, 16.17 mu g g(-1) (Tindal FTA064), thereby demonstrating the role of contaminant loading on release behaviour. The release could also be related to the soil physico-chemical properties. The maximum amount of PFOS was desorbed from the soil with the lowest clay and organic matter content. Bioaccumulation of PFOS in earthworms (Eisensia fetida) as expressed by the bioaccumulation factor (BAF) was found to be highest from soil with the lowest PFOS concentration (RBD soil). The range of BAF found in our study was 1.23 (spiked Tindal SS01 soil) to 13.9 (field contaminated RBD soil). Our study suggests that PFOS could indeed pose a potential risk to ecological safety of soil if present even at concentrations as low as 0.8 mu g g(-1) since the highest bioaccumulation factor was found to be from such a soil (field contaminated RBD).
