Recycled electronic plastic and marine litter
On site determination of trace metals in estuarine sediments by field-portable-XRF.
A portable x-ray fluorescence (XRF) spectrometer and mobile test stand have been employed to examine the feasibility of on site measurements of trace metals in estuarine sediment. In the laboratory, the instrument was able ...
Mechanism of adsorption of actives onto microporous functionalised calcium carbonate (FCC)
Microporous ‘functionalised’ calcium carbonate (FCC) has potential for use as a carrier for the controlled release of ‘actives’, by permeation and diffusion. We have investigated the nature of the FCC surface and the ...
The acute toxicity of thallium to freshwater organisms: Implications for risk assessment.
The acute toxicity of Tl(I) to the microalga, Pseudokirchneriella subcapitata, the planktonic crustaceans, Daphnia magna and Daphnia pulex, and early-life stage of the zebrafish, Danio rerio, has been studied according to ...
Black plastics: Linear and circular economies, hazardous additives and marine pollution.
Black products constitute about 15% of the domestic plastic waste stream, of which the majority is single-use packaging and trays for food. This material is not, however, readily recycled owing to the low sensitivity of ...
Cadmium pigments in consumer products and their health risks
© 2018 Elsevier B.V. Cadmium is a toxic heavy metal that has been increasingly regulated over the past few decades. The main exposure routes for the general public are the consumption of certain foods and the inhalation ...
Microplastics in different tissues of fish and prawn from the Musa Estuary, Persian Gulf.
Commercially-important species of fish and a crustacean from four sites in the Musa estuary and a site in the Persian Gulf have been analysed for the presence and location of microplastics (MPs). A total of 828 MPs were ...
Mobilisation kinetics of hazardous elements in marine plastics subject to an avian physiologically-based extraction test.
Samples of plastic collected from two beaches in southwest England (n = 185) have been analysed by XRF spectrometry for elements that are hazardous or restricted in synthetic polymers (namely, As, Ba, Br, Cd, Cr, Hg, Pb, ...
Concentrations and Migratabilities of Hazardous Elements in Second-Hand Children's Plastic toys.
(American Chemical Society, 2018-03-06)
About 200 second-hand plastic toys sourced in the UK have been analyzed by X-ray fluorescence spectrometry for hazardous elements (As, Ba, Cd, Cr, Hg, Pb, Sb, Se) and Br as a proxy for brominated flame retardants. Each ...
