“…However, Cu and Pb concentrations measured 8 years prior to the Aurul failure (UNEP 2000) are generally higher than those measured after the mining accident, highlighting the historical, and ongoing, importance of other municipal and industrial sources in contributing to the contaminant-metal levels. Similarly, work by Stoica et al (2000), found elevated concentrations of Al (1.8 -4300 mg/l) and Pb (1 -163 mg/l) in the water of the Arges River, a Romanian tributary of the River Danube that receives metal inputs not associated with metal mining activity, but with industrial and municipal sources in the Bucharest region.…”

The European Union Water Framework Directive represents a new, holistic approach to safeguarding water quality and improving aquatic ecosystems. The challenges faced by managers of multinational river basins are highlighted in the River Danube system, which covers an area exceeding 800,000 km 2 , incorporating all or part of 14 countries. This study investigates the challenges faced with attempting to achieve and maintain 'good' status for water quality due to the widespread occurrence of metal mining activity throughout the Danube drainage basin. The release of contaminant metals (notably Cd, Cu, Pb, Zn) and As from point and diffuse sources results in solute metal loads within certain affected rivers that exceed 3000 kg/day, causing metal concentrations to exceed water quality guidelines by up to 280 times and giving rise to the associated degradation of aquatic environments. Within mining-affected catchments, contaminant metals and As are being dispersed over a variety of spatial scales, with the dispersal of sediment-associated metals occurring over hundreds of kilometres resulting in the mobilization of contaminants across international borders. Establishing efficient contamination management and remediation strategies within the Danube drainage basin will be influenced by predicted increases in winter flood frequency, which will potentially increase the mobilization of contaminants from point and diffuse sources.

“…1 A great number of analytical methods have been developed over the past decades, using techniques like atomic absorption spectrometry, 2 inductively coupled plasma (ICP) mass spectrometry (MS), 3 and electrochemistry. 4 The involvement of sophisticated instruments and complicated sample pretreatment in these methods makes them not suitable for at-the-field detection to promptly recognize the onset of contamination.…”

Combing DNAzyme with single-walled carbon nanotubes for detection of Pb(ii) in water

A sensitive and simple assay for the detection of Pb(2+) in aqueous solutions is reported. It takes advantage of the high affinity between single-stranded DNA (ssDNA) and single-walled carbon nanotubes (SWCNT) as well as the capability of SWCNT in fluorescence quenching. Lead(II) catalyzes the cleavage of a fluorescently labeled DNA substrate by a DNAzyme, which releases the single-stranded product to be adsorbed onto a SWCNT. The decrease in fluorescence is proportional to the Pb(2+) concentration. Concentrations as low as 1 nM Pb(2+) in water could be detected and the detection range spans over 5 orders of magnitude. The unique combination of Pb-specific DNAzyme with SWCNT produces a universal, facile and cost-effective sensing platform for lead ions. The concept can be applied to the design of detection assays for other metal ions or small molecules.
