The present study examines the influence of Ca2+ as (CaSO4), dissolved organic carbon (DOC) and pH on chronic water-borne lead (Pb) toxicity to the larval fathead minnow (Pimephales promelas) under flow-through conditions. The 30 day LC50 for low hardness basic test water (19 mg CaCO3 L(-1)) was 39 (range: 27-51) microg dissolved Pb L(-1) and was greatly increased by increasing concentrations o...

The contamination of ecosystems in areas around waste dumps is a major threat to the health surrounding populations. aim this study understand contribution Hulene-B dump (Maputo, Mozambique) edible plants, rhizosphere soils, stream waters, and groundwater, assess human risk. Soil plant samples were analyzed by XRD XRF for mineralogical chemical composition characterization, respectively. Minera...

The detrimental effects of inorganic scaling in industrial and domestic applications are often mitigated with scale inhibitors. Increasing environmental awareness stringent regulations require developing more sustainable antiscalants. Testing suitable candidates is the rate-limiting step development cycles, therefore we developed a high-throughput methodology to rapidly evaluate antiscaling pot...
