Tetrabromobisphenol-A (TBBPA) and its analogue compounds (bisphenol-A (BPA) and 2,6-dibromophenol (2, 6-DBP)) sorption on CTMAB-clays was investigated in this paper through bath experiments. Montmorillonite and kaolinite modified by CTAMB, as the adsorbent, were firstly characterized by XRD, FTIR and SEManalysis. The surface areas was determined using N2 (77K) sorption-desorption analysis. Kinetic...
Industrial parks are a typical way for economic development in China, which has produced and consumed most polybrominated diphenyl ethers (PBDEs). All samples were collected around an industrial park in May and October 2011, which are extracted XAD-2 and XAD-4 resin and tested by GC-MS (Agilent 7890A/5975C). The mean levels of Σ₈PBDE in water, sediment, and soil are 5.53 ng/ml, 37.54 ng/g dw and 22...
The rate and factors determining changes in the soil carbon pool after afforestation are still poorly understood, especially in arid and semiarid areas. This paper provides a review of the influence effect of afforestation on soil organic carbon (SOC) stocks based on a meta-analysis of 37 publications (including a total of 116 observations in the past 10 years), with the aim of exploring the major...
