ABSTRACT This study investigated the variances in soil microbial community (SMC) structure and metabolic potentials in subtropical mountain forest ecosystem. Soil samples (0–10, 10–30 and 30–60 cm) were collected within 27 plots (20×20 m2) that were randomly assigned. Changes in SMC structure were mainly regulated by soil physicochemical property and tree diversity in 0–10 cm depth, by total nitrogen

ABSTRACT o -Dichlorobenzene could be mineralized as the sole carbon and energy source by Bacillus cereus DL-1. In this work, Haldane–Andrews and pseudo-first-order models were used to simulate the growth and degradation abilities of the strain. Two possible degradation pathways were identified by GC/MS intermediate and open-loop analysis. The removal efficiency (RE) of biotrickling filter (BTF) could

ABSTRACT The aim of this study was to evaluate changes in lead and chromium amounts in sequentially separated fractions and available forms of four sewage sludge (SS). Lead and chromium sequential extraction in SS was performed using BCR method. Single extractants were used to assay available and bioavailable forms of metals. It was found that Pb and Cr were detected in the largest amounts in organic

ABSTRACT This study aimed to assess the impacts of industrial activities in Ogun State, Nigeria. A total of 96 samples were collected both in dry and wet seasons for analysis of physicochemical quality indicators. Hydrochemical assessment were carried out according to APHA standard while hydrochemical facies of groundwater samples was evaluated using Piper Trilinear software. Pearson correlation was

ABSTRACT Surficial sediment samples along the coastal area of the province Thai Binh in Vietnam have been collected and analysed by modified Tessier method for the mercury content. The mercury levels in these samples were found in the range between 0.12–3.79 mg/kg. Elevated concentrations were observed in some locations close to tidal marshes, large aquaculture productions or low-lying areas. The highest

ABSTRACT Samples of PM2.5 particulates were collected from indoor air of 36 cafés, 14 cafés in which only water pipe (WS) was used, eight in which only cigarette was smoked (CC), six in which both waterpipe and cigarette were smoked (WCC), and eight cafés in which no smoking occurred (SFC) in Tehran. After that, the concentration of lead (Pb), cadmium (Cd), nickel(Ni), and chromium (Cr) was examined

ABSTRACT The present work was conducted in a two-part study. In part I, the levels of indoor and outdoor PM10, PM2.5, and PM1 was measured using real time GRIMM dust monitors. In part II, the performance of NAIs method was investigated on reduction of indoor concentration of PM in these residential buildings for the first time. Hourly average concentration and standard deviation (SD) of PM10 in indoor

ABSTRACT The focus was to assess the effects of biochar on Cd uptake by various vegetables and its downward movement in saline-alkali soil and carried out in polluted pots experiment. The results showed that the biomass of vegetables increased significantly by 16.9% to 519.9% while the Cd concentration in green pepper and eggplant fruits was decreased by 6.8% to 11.5% and 15.1% to 15.4% with the biochar

ABSTRACT To determine the concentration of benzene series (BTEX) compounds, 33 samples were collected from indoor air of Ghalyan cafés (GHC), cigarette cafés (CC) and smoking-free cafés (SFC) in Bushehr city, Iran, and analyzed using gas-chromatography - flame ionization detector (GC-FID). The results of this study indicated that the mean±SD values of ΣBTEX in GHC, CC and SFC cafés were 19.46 ± 6.07

ABSTRACT A constructed wetland system with Acorus calamus (A. calamus) was developed to investigate the purification efficiency of petroleum-containing wastewater. High-throughput sequencing was employed to investigate bacterial richness and diversity, bacterial community structure variation between spring and summer, and the effect of bacteria on petroleum-containing wastewater purification in the

ABSTRACT The effects of straw input, including three strategies: chopped straw, straw-derived compost and biochar, on bacterial communities and chemical composition in maize rhizosphere were investigated according to a three-year field experiment. Illumina MiSeq sequencing showed that biochar input increased bacterial richness but decreased bacterial diversity in rhizosphere when compared with the

ABSTRACT The pyrolysis treatment can effectively reduce the sewage sludge volume and fix its nutrients for land application. The synergistic effect on the fixation of nutrients can be better exerted by the sewage sludge biochars (SSB) prepared by the co-pyrolysis method. In this study, SSB was prepared by adding stalks and mineral materials in to sewage sludge that was used as the base material. The
