Croplands are often suffering from sand burial in dry regions of northern China.For studying this phenomenon,we carried out a case study of field experiment including four sand burial levels,i.e.shallow(1–3 cm),moderate(8–12 cm)and deep(15–20 cm)sand b

以上海市2家污水处理厂为对象,对比了SMT法与碱性过硫酸钾消解(APPD)法对污泥总磷(TP)的提取效果,应用SMT法分析了污泥处理流程中磷赋存形态的变化规律,探究了污泥中生物可利用磷与TP的关系。结果表明,SMT法对污泥磷的提取较APPD法更为彻底,深度脱水污泥含磷量明显低于其他污泥。无机磷(IP)为污泥中磷的主要形态,占TP的62%以上;IP中又以磷灰石磷(AP)为主,特别是深度脱水污泥中,A
采用化学还原与电沉积方法制备了钯和石墨烯复合膜碳纸(Pd/r GO/C)电极。以制备的Pd/r GO/C电极为阴极,通过电化学还原法处理水中硝酸盐。结果表明,与碳纸(C)、石墨烯修饰碳纸(r GO/C)、钯修饰碳纸(Pd/C)电极相比,Pd/r GO/C电极对于硝酸盐还原具有更高的电催化活性及N2选择性。Pd和r GO具有良好的协同催化还原硝酸盐作用。当外加电压由-0.75 V降至-1.0 V时,
室内灰尘是人体对多溴二苯醚(PBDEs)暴露的重要乃至主要途径.吸尘器收集的灰尘中PBDEs的含量与室内人员血液中该物质含量的相关性较差,不适用于估算人体暴露剂量,也不能研究其沉降通量及其季节变化,用被动采样法采集室内降尘则可弥补这些不足.在厦门市选取家庭、办公室、机房和家具厂等采样点49个,用水平放置的玻璃板(四周用洁净铝箔围起)采集一年四季的降尘样品,对降尘中PBDEs的沉降通量、含量、组成、
用气相色谱-质谱法(GC-MS)定量分析了2013年9月南昌市PM_(2.5)中16种优控多环芳烃(PAHs)含量.结果表明,PAHs总浓度平均值为17.95 ng·m~(-3),变化范围为3.55—39.97 ng·m~(-3).不同环数多环芳烃占总浓度比例由大到小依次为:5环(50.45%)>4环(19.32%)>6环(17.99%)>2环(6.34%)>3环(5.90%),表现出明显的机动车
