Optimizing the synthesis process of wood-derived biomorphic silicon carbide
… to be composed of mainly pure SiC with minor trace metal contamination. Compression testing illustrated better mechanical properties of the Si prepared specimen, suggesting the potential of this method to replace existing techniques.

Nanoparticle - Heavy Metal Associations in Riverbed Sediments
Relationships between trace metals and nanoparticles were investigated using analytical transmission electron microscopy (aTEM) and asymmetric flow field flow fractionation (aFlFFF) coupled to both multi-angle laser light scattering (MALLS) and high resolution-inductively coupled plasma mass …

Assessment of coastal aquifer contamination using geochemical and health risk assessment in Maputaland formations, South Africa
… This could possibly increase the risk of aquifer contamination.The main objectives of this study is to evaluate the hydrogeochemical processes, identify the intended sources of groundwater contamination, and understanding the extent of trace metal contamination and health risk assessment. In this …

Uranium in groundwater and its potential as a natural contaminant in the Cherokee Basin, southeastern Kansas
… studies have focused on anthropogenic uranium contamination. Here, we examined the potential for natural uranium contamination from water-rock interaction in black shales. After uranium ores, black shales are the second most important uranium source. Immobile uranium can be mobilized and …

THE SHORT- AND LONG- TERM EFFECT OF ZINC AND COPPER CONTAMINATION ON SOIL MICROBIAL FUNCTIONS
… ecological health. The inadvertent release of trace metals into soil ecosystems through their extraction, processing, and use of metal ores has led to elevated soil trace metal concentrations worldwide. To preserve soil ecosystem functions and soil health, soil regulatory limits that define …

Macrobenthic community and ecotoxicological status of the Nhlabane Estuary
… around the estuary raised concerns about trace metal concentrations in the estuary. This study was initiated following concerns about the ecological integrity of the estuary in relation to reduced freshwater input into the system and its effect on the macrobenthic community, as well as the …
