The rapid increase in the number of electronic products worldwide, in terms of both variety and advanced technology, together with the decrease in costs, has led to the generation of a large amount of electronic waste (e-waste), which has significantly increased environmental pollution. This stud...
Electronic waste is known as “urban mines”, It is an important renewable resources of nonferrous metals. Waste PCB mainly composed of metal and nonmetal materials, Metal materials has greater toughness, and nonmetal materials with higher brittleness. Due to large differences between toughness and br...
the production of Electrical and Electronic Equipment (EEE) is one of the fastest growing sectors of manufacturing industry in the world, expecting a 3-5% increase per year. In parallel, there is a falling life expectancy for electronics, low recycling rates, large variability among the Waste El...
Screen the priority of emerging contaminants (ECs) from sediments is essential for risk assessment to aquatic environment and human health. Currently, priority approaches mainly focus on contaminant identification, exposure analysis, risk assessment, and
qualitative monitoring approaches are addressed by the department G4. A high proportion of the specialized tasks is carried out in cross-departmental areas within the division G and in cooperation with the divisions Ecology (U) and Quantitative Hydrology (M). Each of these task areas contains ...
in order to have more functions and maintain battery area. As a result, the proportion of 0402 (01005″) parts is expected to grow in the future and reach around 20% by 2025. 0201 mm (008004″) parts are also expected to see increased usage through 2022. In addition to the ...
Furthermore, the proportion of publications focusing on the health outcomes of PFOA and PFOS indicates a higher emphasis on PFOS exposure (47.8%) as compared to PFOA (38.6%). Furthermore, the presence of mixture forms of contaminants, including parent compounds, metabolites, and other chemical ...

Perhaps the most important characteristic of a MOSFET used in an electronic load is its ability to dissipate waste heat. The total power in the load (PL) is obviously the product of load current and the voltage under test: PL= ILOADx VDUT ...
The high proportion of BDE209 in the soil samples implies that the main sources of PBDEs in the e-waste dismantling site were deca-BDE commercial products. Penta-BDE industrial products were also important sources of PBDE contamination in this region. 3.2. Bioavailability of PBDEs measured in ...
