Diffusive gradient in thin-films (DGT) as risk assessment and management tools in the Central Witwatersrand Goldfield, South Africa
Diffusive gradient in thin-films (DGT) technology was used to monitor bio-available metals and the tool was developed for risk-based pollution assessment and liability apportionment in the Witwatersrand Goldfields, South Africa, where there is widespread mine-related pollution. DGT technology is a passive sampling technique whereby metal species are selectively diffused from polluted water thro...
متن کاملIn situ Measurement of Trace Metals in Estuarine Waters of Patos Lagoon using Diffusive Gradients in Thin Films (DGT)
A técnica de gradiente difusivo de membrana (DGT) foi utilizada para determinar metais lábeis in situ durante diferentes condições hidrológicas no estuário da Lagoa dos Patos. As amostras de água foram também analisadas para a fração lábil-Chelex para Cd, Co, Cu, Mn, Ni e Zn usando resina Chelex-100. As concentrações lábeis-DGT de Cd, Cu, Ni e Zn foram mais baixas que a lábil-Chelex, possivelme...

15 صفحه اولThe Diffusive Gradients in Thin Films Technique (DGT) for Trace Metals versus Active Sampling
The diffusive gradient in thin films (DGT) technique is an in situ passive sampling method that is designed to accumulate labile metal species in environmental systems. DGTs were applied for the determination of time integrated concentrations of low level dissolved metals in waters in areas of ecological concern. The data revealed heavy metal contamination of waters and tracked the contaminatio...
متن کاملA New Profile Measurement Method for Thin Film Surface
In order to measure the surface profile of the thin films in wide area with high accuracy, the research on the new measurement method was conducted and many patents on measurement method and system were researched. Based on the physical properties of soft thin film, the method of using white interferometer and ball cantilevers for measuring the surface profile of thin film is proposed. Then, th...
