Application of a novel cold activated carbon fiber-solid phase microextraction for analysis of organochlorine pesticides in soil

A novel and simple analytical procedure using cold activated carbon fiber-solid phase microextraction (CACF-SPME) was applied to determine organochlorine pesticides (OCs) in soil samples. The pesticides in this study consist of α -, β -, γ -, and δ -hexachlorocyclohexane (HCH). By heating the sample while cooling the fiber, the developed method not only provides better performance in terms of sensitivity, linearity and recovery but also offers shorter adsorption procedure than that of traditional headspace-solid phase microextraction (HS-SPME). The experimental conditions such as the amount of water, adsorption time and adsorption temperature were optimized. Matrix effects were investigated with different types of soils. We concluded that using the standard addition method was required for quantification purposes. The limits of detection obtained using the proposed method range from 0.01 to 0.05 ng/g, and the recoveries for CACF-SPME are in the range of 80.01% to 89.68% with relative standard deviation (RSDs) better than 8.60%. The proposed method was further applied to determine OCs in real agricultural soil. The results are in good agreement with those obtained using traditional ultrasonic extraction. The research demonstrates the suitability of the CACF-SPME for the analysis of OCs in soil.

Crowding-out effect of coal industry investment in coal mining area: taking Shanxi province in China as a case

The rapid development of coal industry in Shanxi province in China has important effects on its economic development. A large amount of money has been invested into the coal industry and other related industries during the recent years. However, research on the investment effect of Shanxi’s coal industry was rare. In order to analyze the investment effect of coal industry, based on the crowding-out effect model, cointegration test, and the data available in Shanxi Statistical Yearbooks, this paper calculates the effect between coal industry investment and other 17 industry investment. The results show that the investment of coal industry produces crowding-out effect on food industry, building materials industry, and machinery industry. Increasing 1% of the coal industry investment can reduce 0.25% of the food industry investment, or 0.6% of building materials industry investment, or 0.52% of the machinery industry investment, which implies that Shanxi province should adjust coal industrial structure, promote the balance development of coal industry and other industries, so as to promote its economic growth.

     

用丁苯橡胶滤柱处理含油废水的研究

研究了用丁苯橡胶滤柱处理含油废水的可行性,探讨了不同条件下对含油废水破乳除油的影响参数,并对实际废水进行了处理。结果表明,在滤柱高50mm、线流速为3mL/s、水温为20℃的条件下,对含油量为500～600mg/L的含油废水进行处理,去除率可达80%左右。因此,该滤柱可用于含油废水的初级处理。

南京市典型快速路交通噪声监测与影响分布研究

为科学全面地开展城市道路交通噪声影响评估，更精确地服务道路交通噪声污染治理工作，选取南京市具有代表性的道路交通干线，采用手工监测和自动连续监测的方法，进行不同路段噪声污染程度及其随时间、空间变化规律的研究。结果表明，地面快速路段、高架路段以及衔接路段两侧噪声敏感建筑物受道路交通噪声影响较大，夜间均超标；相邻区域要达到2类声环境功能区昼间标准限值要求，需距离地面快速路慢车道约45 m，距离高架路段慢车道约92 m；要达到2类声环境功能区夜间标准限值要求，需距离地面快速路慢车道约175 m，距离高架路段慢车道约172 m；敏感建筑物所受噪声影响随楼层高度升高而增大，同时噪声影响情况与道路两侧建筑物密度、道路车辆行驶速度有关。建议严格道路及噪声敏感建筑物规划控制，采取阻断传声路径、受声建筑物强化保护等措施控制噪声影响。     

山西省能源圈辐射的环境效应

根据历年<山西统计年鉴>提供的能源输出数据,分析了1985-2007年间山西省煤炭的输出情况,并借助于GIS软件,分析了2006年山西省煤炭的流向及流量.山西省是一个大的能源辐射基地,每年产出煤炭的三分之二左右供应外省市,在外省市的经济水平、人民生活质量不断得到提升的同时,对于为周边地区的发展做出巨大贡献的能源输出地--山西来说,人均地区生产总值却低于全国平均水平,更低于其能源辐射到的其它省市区.山西省在不断向外省市输出能源的同时,也产生了巨大的环境辐射效应,但这种效应对于山西这个能源输出地来说却是负向的.主要表现在:山西省由于煤炭开采导致空气污染、地下水位下降、地面塌陷等地质灾害,而这些环境压力有三分之二是替煤炭输入地所承担的.输送电力,山西省不仅要承担煤炭开采造成的环境破坏,还要承担火力发电所造成的巨大环境二次污染,仅2007年,山西省生产外调电量就产生381.75×10~4 tSO_2,139.98×10~4 tNO_2,2799.51×10~4 t灰粉.
