Objective: PM₁₀ is one of the typical pollutants involved with sandstorm. More and more attentions on the sensitive bio-marks by PM₁₀ exposure are attracted. This study is to probe the sensitivities indicators’ levels by sandstorm PM₁₀ exposure. Methods: A cross-sectional study involving administration on a survey 150 residents in Erlianhaote was performed. PM₁₀ concentrations collected on a daily basis from the local monitor stations from March to June, 2016 were employed as the daily environmental exposure levels (DEEL). Indicators of IGM, CRP, CC16, IL16, IGA, LGG, IGE and IL8 were assayed, as well as questionnaire for individual disease histories were done. Results: Results indicated that PM₁₀ exposure level was positively related to IGG, IGM, IGA, LGG and CRP, age was positively related to CRP and LGG, and history of cardiovascular disease was related to CRP by multi-factor line regression analysis. Further analysis revealed that levels of IGG (p<0.01) and IGM (p<0.05) increased in the group with PM₁₀ DEEL exceeded 200 μg/m³, compared to the group with the average exposure levels less than 200 μg/m³;while levels of IGM (p<0.05), IGA (p<0.05), LGG (p<0.05) and CRP (p< 0.01) were found higher in the group with PM₁₀ DEEL exceed 300 μg/m³, compare to the group with the levels less than 300 μg/m³. Conclusion: Our findings suggest that sandstorm PM₁₀ exposure might contribute to the changes of some immune and inflammation index. These findings provide clinical indicators for the sandstorm PM₁₀ exposure and help to understand the risk of sandstorm pollution. © The Korean Society of environmental Risk assessment and Health Science and Springer 2018.

Based on TM remote sensing image and topographic map, the spatial information of landscape pattern was extracted in Hulunbeier steppe in 1995, 2000, 2005 and 2010. With the principles and methods of landscape ecology, landscape fragmentation index, division index, dominance index and fragility index were selected to construct the ecological safety index which was used to quantitatively analyze the dynamic changes of landscape pattern and elucidated ecological safety status in study area. Result showed that the overall landscape tended to become fragmentized and complicated with the total number of patches increasing in the study area from 1995 to 2010. The ecological safety index of landscape types can be classified into four grades, grassland > unused land, wood land > water body, crop land > construction land. Overall, the regional ecological safety status got worse with the ecological safety index of natural landscapes decreasing and the ecological safety index of artificial landscapes increasing. In particular, the area of construction land had a continuous increase with a higher growth rate (7.41% per year during 2005~2010), which will be unfavorable to regional ecological safety as the biggest potential risk. © (2013) Trans Tech Publications, Switzerland.

The influence of three effluent organic matter （EfOM） model compounds, humic acid （HA）, bovine serum albumin （BSA）, and sodium alginate （AGS）, on the ozonation ofbezafibrate （BF）, a typical pharmaceutical and personal care product （PPCP）, was investigated. The results show that ozonation efficiently removed BF from aqueous solution with removal efficiencies 〉 95% within 8 min for all conditions. The reaction rate of BF decreased with increasing model compounds concentrations and the influence was more pronounced for HA and BSA, while less pronounced for AGS. Although BF concentration was significantly reduced, the degree of mineralization achieved was only approximately 11%. The addition of HA and BSA improved the mineralization of the solution, while the influence of AGS was minor. The acute toxicity of BF solution during ozonation was determined using the Luminescent bacteria test, and the toxicity exhibited an initial increase and a successive reduction. An overall decreased acute toxicity was observed with an increase of HA. The presence of BSA increased the formation rate of toxicity intermediates and resulted in inhibition peak forward.

Frontiers of Chemical Science and Engineering 2017年第3期11卷 328-337页

Crittenden Key Laboratory of Energy Thermal Conversion and Control (Ministry of Education) School of Energy and Environment Southeast University Nanjing 210096 China State Environmental Protection Key Laboratory of Environmental Risk Assessment and Control on Chemical Process School of Resources and Environmental Engineering East China University of Science and Technology Shanghai 200237 China Brook Byers Institute for Sustainable System School of Civil and Environmental Engineering Georgia Institute of Technology Atlanta GA 30332-0595 USA

Two types of lignin-based carbon fibers were prepared by electrospinning method. The first was activated with Fe304 （LCF-Fe）, and the second was not activated with Fe3O4 （LCF）. Gas phase adsorption isotherms for toluene on LCF-Fe and LCF were studied. The gas phase adsorption isotherm for 0% RH showed LCF-Fe have about 439 mg/g adsorption capacity which was close to that of commercially available activated carbon （500 rag/g）. The Dubinin-Radushkevich equation described the isotherm data very well. Competitive adsorption isotherms between water vapor and toluene were measured for their RH from 0 to 80%. The effect of humidity on toluene gas-phase adsorption was predicted by using the Okazaki et al. model. In addition, a constant pattern homogeneous surface diffusion model （CPHSDM） was used to predict the toluene breakthrough curve of continuous flow-packed columns containing LCF-Fe, and its capacity was 412 mg/g. Our study, which included material characterization, adsorption isotherms, kinetics, the impact of humidity and fixed bed performance modeling, demonstrated the suitability of lignin-based carbon fiber for volatile organic compound removal from gas streams .

Nanoplastics (NPs) can be absorbed by crop roots and translocated to shoots, but whether the process follows a unidirectional pathway in different plant species remains unclear. This study investigated the translocation and accumulation of europium-labeled polystyrene NPs in cucumber (dicot) and maize (monocot) seedlings using a split-root system. The results showed that NP accumulation was highest in exposed roots (E-R), followed by unexposed roots (UE-R), and then shoots in both plants. In cucumber, NP accumulation in E-R was 26.84 % higher than in maize; while in maize, the translocation factor from shoot to UE-R was 4.45 times greater than in cucumber. TEM images confirmed NP transport from root to shoot via xylem, while confocal images showed the redistribution of NPs from shoot to root via phloem. AgNO 3 treatment (5–50 μmol L −1 ) revealed aquaporin-mediated regulation of NP accumulation, with concentration-dependent increases of 30.37–220.7 % in cucumber roots and 36.38–53.65 % in maize shoots. Transcriptomic analysis revealed that NP accumulation interacted with aquaporin gene expression, where differential regulation of tonoplast intrinsic, plasma membrane intrinsic, and nodulin 26-like intrinsic proteins drove translocation differences. This study offers critical insights into the “root-to-shoot-to-root” translocation of NPs, informing crop safety assessments amid global plastic pollution.
