“…All solutions were analysed within a month using a Jarrell Ash ICP-AES. Each batch of samples included duplicates, blanks and a certified reference material (CRM 601) (Quevauviller et al 1997). Detection limits (ppm) of the ICP were Pb 0.1, Zn 0.01, Cu 0.03, Cd 0.02, Fe 0.06 and Mn 0.02.…”

Purpose Despite the decline of metal mining in the UK during the early 20th century, a substantial legacy of heavy metal contamination persists in river channel and floodplain sediments. Poor sediment quality is likely to impede the achievement of 'good' chemical and ecological status for surface waters under the European Union Water Framework Directive. This paper examines the environmental legacy of the Dylife lead/zinc mine in the central Wales mining district. Leachable heavy metal concentrations in the bed sediments of the Afon Twymyn are established and the geochemical partitioning, potential mobility and bioavailability of sediment-associated heavy metals are established.Materials and methods Sediment samples were collected from the river bed and dry-sieved into two size fractions (<63 µm and 64-2,000 µm). The fractionated samples were then subjected to a sequential extraction procedure to isolate heavy metals (Pb, Zn, Cu, Cd, Fe, Mn) in three different geochemical phases. Sediment samples were then analysed for heavy metals using ICP-AES. 2Results and discussion The bed sediment of the Afon Twymyn is grossly polluted with heavy metals.Within the vicinity of the former mine, Pb concentrations are up to 100 times greater than levels reported to have deleterious impacts on aquatic ecology. Most heavy metals exist in the most mobile easily exchangeable and carbonate-bound geochemical phases, potentially posing serious threats to ecological integrity and constituting a significant, secondary, diffuse source of pollution. Metal concentrations decrease sharply downstream of the former mine, although there is a gradual increase in the proportion of readily extractable Zn and Cd.Conclusions Implementation of sediment quality guidelines is important in order to achieve the aims of the Water Framework Directive. Assessments of sediment quality should include measurements of background metal concentrations, river water physico-chemistry and, most importantly, metal mobility and potential bioavailability. Uniformity of sediment guidelines throughout Europe and flexibility of targets with regard to the most heavily contaminated mine sites are recommended.

“…They use different reagents or extractants that preferentially leach, step-by-step, precipitated, adsorbed or complexed metal, avoiding an attack on the lithogenic residual fraction. The results obtained mainly depend on how the extraction is carried out, and therefore they are operationally defined (Nirel and Morel 1990 (Ure et al 1993;Quevauviller et al 1997;Rauret et al 1999;Gómez-Ariza et al 2000).…”

Contents of total Hg and Hg fraction, organic matter, pH, grain size and chemical composition were measured to investigate the pollution characteristics and binding behavior of Hg in soils collected from the Chatian Hg mining deposit (CMD), southwestern China. The average concentration of Hg concentration in the CMD soils was 155 and 1,315 times higher than that in control soils and Chinese soils, respectively, suggesting that the CMD soils were heavily contaminated by the element. The finding was confirmed by Müller geoaccumulation index assessment with 75% very seriously polluted, 6.25% highly to very highly polluted and 18.75% moderately to highly polluted. Hg sources in the region were natural and anthropogenic: in addition to the pedogenic process and original geochemical situation, human miningrefining activities have also seriously impacted the redistribution of Hg in soils, especially in paddy soils.

“…This was later revised to include an additional, residual step (an aqua regia digestion) (Rauret et al 1999). Reference materials (BCR 601 and BCR 701) certified for metals extractable by the BCR procedure were produced for use in validation of extraction results (Pueyo et al 2001;Quevauviller et al 1997). The BCR protocols are now applied widely to investigate the potential 4 mobility of trace metals, not only in soils and sediments, but also in matrices such as sewage sludge (Perez-Cid et al 1996), dust (Tokalioglu et al 2003) and compost (Greenway and Song 2002).…”

Application of risk assessment codes and Hankanson potential risk indices indicated that Cd was the element of greatest concern in the Lagos Lagoon system. The study indicated that there is a need to strengthen environmental management and pollution control measures to reduce risk from PTM, but that even relatively simple strategies, such as seasonal restrictions on dredging and fishing, could be beneficial.
