A multimedia fate model with spatially resolved air and soil phases was developed evaluated. The used for calculation of phenanthrene concentrations in air, water, soil, sediment Tianjin area transport fluxes between the adjacent bulk under steady-state assumption. Both were divided into 3113 individual compartments 4 km2 each to assess spatial variation fluxes. Independently measured validation. validated using a set 188 surface samples collected from area. Most data either or validation...
A level III fugacity model was applied to characterize the fate of gamma-HCH in Tianjin, China, before 1990s when contamination reached its maximum at steady state. Geometric means were used as inputs. The concentrations air, surface water, soil, sediment, crops, and fish well transfer fluxes across interface between compartments derived under assumption calculated validated by independent data collected from literature. There generally good agreement estimated observed concentrations,...
Particulate matter (PM) is a major ambient air pollutant causing millions of premature deaths each year in China. The toxicity PM property and size dependent. In this study, samples collected Beijing were divided into five fractions with nominal aerodynamic ranges <0.40, 0.40–1.1, 1.1–3.3, 3.3–5.8, 5.8–10 μm. Individual characterized for number properties including particle distribution, specific surface area, zeta potential, dithiothreitol (DTT)-based redox ability, contents water-soluble...
A passive sampler which can be used to collect both gaseous and particulate phase polycyclic aromatic hydrocarbons (PAHs) in air was previously developed calibrated. The successfully a field study North China Plain. However, the relatively low uptake rate for PAHs prevented it from being applied nonseverely contaminated environment. redesigned increase calibrated individual PAH compounds of various molecular sizes. effect fine-screen-mesh wrapping on performance tested. It found that...
Neuromuscular conduction dysfunction-induced underactive bladder (UAB) is a major urological complication associated with diabetes mellitus (DM), and there remain deficiencies in reliable pharmacological treatment options. Astragalus polysaccharides (APS), as an edible active substance membranaceus, have therapeutic effect on its complications. We investigated the effects mechanism of APS high-fat-diet-induced (HFD) diabetic UAB mice. significantly reduced fasting plasma glucose, insulin,...
Rice serves as a vital staple food, but its accumulation of cadmium (Cd) has sparked widespread concerns regarding food safety and ecosystem security. Here, we conducted seven-year systematic field experiment in the Xiangjiang River Basin China, where an integrated governance framework (IGF) was established to ensure rice safety. The IGF, tailored geographical zoning pollution gradation, includes targeted soil treatments, crop management strategies, stakeholder engagement. quality both...
A simple surface-enhanced Raman spectroscopy (SERS) sensor based on an undecorated gold-colloid substrate was developed for the rapid and effective detection of polycyclic aromatic hydrocarbons (PAH). The SERS enhancement bare Au nanoparticles PAH achieved by adjusting chemical reduction conditions Cl- content. strongest response this system with 2.0 mL trisodium citrate (1%) 80 μL NaCl (1 M). With sensor, qualitative quantitative determination trace-level naphthalene (NaP), phenanthrene...
Screening high-tolerant microorganisms to cadmium (Cd) and revealing their bio-obstruction mechanism could be significant for Cd regulation from farmland the food chain. We examined tolerance bio-removal efficiency of ions two bacterial strains, Pseudomonas putida 23483 Bacillus sp. GY16, measured accumulation in rice tissues its different chemical forms soil. The results showed that strains had high Cd, but removal was decreased successively with increasing concentrations (0.05 5 mg kg-1)....
Using both stationary air samplers and personal samplers, concentrations of total suspended particulates, particulate matter with a diameter less than 2.5 μm, elemental carbon, organic carbon were measured in the kitchen, bedroom, outdoors rural, nonsmoking household northern China. The used traditional biomass cookstove winter summer more modern liquified petroleum gas on first day summer. Most indoors exceeded national quality standards China (0.15 mg/m3 for indoor 10 μm or less; 0.30...
