Abstract. Many studies have demonstrated associations between exposure to ambient particulate matter (PM) and adverse health outcomes in humans that can be explained by PM capacity induce oxidative stress vivo. Thus, assays been developed quantify the potential (OP) of as a more refined metric than mass alone. Only small number compared different acellular OP measurements for given set samples. Yet, fewer over year-long period with detailed chemical characterization PM. In this study, we...
Coal mining in China is continually increasing, and the associated emitted coal mine dust of growing environmental occupational concern. In this study, deposited (DD) was analysed three different regions an active, highly-volatile bituminous open-pit Xingjian Province, Northwest China: working fronts, tailings handling sites, road traffic sites. Samples were for particle size, geochemical mineralogical patterns, then compared with respirable DD fractions (RDDs, <4 μm) separated from samples....
Air quality in subway systems is of interest not only because particulate matter (PM) concentrations can be high, but also the peculiarly metalliferous chemical character particles, most which differ radically from those outdoor ambient air. We report on oxidative potential (OP) PM2.5 samples collected Barcelona system different types stations. The PM composition these showed typically high Fe, Total Carbon, Ba, Cu, Mn, Zn and Cr sourced rail tracks, wheels, catenaries, brake pads...
We focus on a comparison of the geochemistry and mineralogy patterns found in coal, deposited dust (DD), respirable (RDD) inhalable suspended (PM10) from number underground mines located China, with an emphasis potential occupational health relevance. After obtaining RDD DD, toxicological analysis (oxidative potential, OP) was carried out compared their geochemical patterns. The results demonstrate: i) dependence RDD/DD moisture content for high rank coals that does not exist low coals; ii)...
This study evaluates geochemical and oxidative potential (OP) properties of the respirable (finer than 4 μm) fractions 22 powdered coal samples from channel profiles (CP4) in Chinese mined coals. The CP4 extracted milled different coals were mineralogically geochemically analysed relationships with OP evaluated. evaluation between CP4/CP demonstrated that increased concentrations anatase, Cs, W, Zn Zr, whereas sulphates, Fe, S, Mo, Mn, Hf Ge decreased their concentrations. results ascorbic...
Aim: The increasing number of cancer cases has stimulated researchers to seek for novel approaches. We have combined two bioactive moieties: a polyphenolic scaffold and an organoselenium motif. Four different families (isothiocyanates/thioureas, their selenium isosters) derived from dopamine, (±)-norepinephrine R-epinephrine were accessed. Results: Heterocumulenes dopamine β-O-methylnoradrenaline strong antiproliferative agents (GI50<10 μM). Selenoureas bearing electron-withdrawing groups...
