Night-time OH levels have been determined for UK urban surface environments using two methods,the decay and steady state approximation methods.Measurement data from the UK National Environmental Technology Centre archive for four urban sites(Bristol,Harwell,London Eltham and Edinburgh) over the time period of 1996 to 2000 have been used in this study.Three reactive alkenes,namely isoprene,1,3-butadiene and trans-2-pentene were chosen for the calculation of OH levels by the decay method.Hourly measurements o... 相似文献

Sixty home made wine and sixty-four grape samples were collectedfrom five territories in Jordan, where grapes and wine aremostly producted. The collected samples were analyzed for themost used organochlorine pesticides (OCP) and organophosphorouspesticides (OPP) in Jordan, as well as for four heavy metals(Ni, Cu, Zn and Pb). The results showed that OCPs residues weredetected in 73% of the wine samples but no OPPs residue weredetected which is due to generally shorter half life of thelater pesticide. Grapes showed higher incident of contaminationthan wine, however, OCPs and OPPs with both short and longhalf-lives were detected. The OPPs were detected in only8.3% of the analyzed grape samples. Heavy metals showed higher valuesin grapes than in the wine samples and it was attributed toremoval of solids during wine preparation processes or throughcontamination of wine during storage. Most of the samples werebelow toxic limit. 相似文献

Vehicular Contamination of Dust in Amman, Jordan 总被引:1,自引:0,他引:1
Anwar Jiries 《The Environmentalist》2003,23(3):205-210
Road dust from four traffic areas; the city center, tunnels, closed car parks and a residential area was collected from the urban part of Amman and analyzed for polycyclic aromatic hydrocarbons (PAH) and heavy metals content.Total PAH and selected heavy metals were in the range of a few gg–1. The distribution of PAH was controlled by the arid climatic conditions. PAH distribution in the street dust tended to be dominated by 4- and 6-ring PAHs with significantly less 2- and 3-ring PAH reflecting volatilization of the latter under the hot and dry climatic conditions. However, both PAH and heavy metal concentrations were affected by the densities and conditions of traffic activity at the various sites. Generally, the highest concentrations of both PAH and heavy metals were found in the tunnels and the lowest in the residential areas.Significant correlation between PAH and total organic matter (TOM), lead and cadmium indicated that PAH and heavy metals in street dust of heavily traffic areas are strongly affected by automobile exhaust emission and that those in the residential areas have another source, most probably street material erosion. 相似文献

昌吉市不同景观土壤动物群落结构 总被引:1,自引:0,他引:1
为了解不同利用方式土地的春季土壤动物群落结构,于2007年3月至6月对昌吉市周围的5种土地,即天然林、人工林、草地、农田、废弃地进行取样调查,共捕获土壤动物2 046只,隶属3门10纲24目.分析表明:土壤动物优势类群为昆虫纲(Insecta)、蛛形纲(Arachnida)、弹尾纲(Collembola),常见类群为腹足纲(Gastropoda)、寡毛纲(Oligochaeta)、软甲纲(Malacostraca)和双尾纲(Diplura)等,其他均为稀有类群.5种不同利用方式土地土壤动物群落物种多样性和均匀度指数有一定的差异,草地的物种多样性最大,废弃地的多样性最小,体现了群落的复杂性与多样性.垂直分布显示土壤动物具有明显的表聚现象.根据土壤动物群落聚类的结果,可将5中土地分为2组,即草本植物种植型、林地型.显示了土壤动物群落对土壤利用方式的响应情况. 相似文献

新疆和硕绿洲采集82个耕地土壤样品,测定其中As、Cd、Cr、Cu、Mn、Ni、Pb和Zn等8种重金属元素的含量。采用地统计法、污染负荷指数(PLI)和潜在生态风险指数(RI)评估农田土壤重金属污染和潜在生态风险,并讨论重金属主要来源。结果表明:(1)和硕绿洲农田土壤所有重金属元素含量平均值均未超出国家二级标准的限值,Cd、Cr、Ni、Pb和Zn含量的平均值分别超出新疆灌耕土背景值的2.0、1.51、1.18、2.13和8.47倍。(2)农田土壤Cd与Zn呈现中度污染,Cr、Cu、Ni和Pb轻度污染,Mn轻微污染,As无污染。研究区PLI平均值呈现轻度污染。(3)各重金属元素单项生态风险指数从大到小依次为:Cd、Ni、As、Cu、Cr、Zn与Pb。农田RI平均值属于轻微生态风险。重金属元素含量、污染与生态风险空间分布格局各不相同。(4)和硕绿洲农田土壤As、Pb和Zn主要受到人为因素的影响,Cr、Cu、Mn和Ni主要受到土壤地球化学作用的影响,Cd受人为污染和自然因素共同影响。Cd是研究区农田土壤主要的污染因子之一,对农田土壤污染及潜在生态风险的贡献较大,农田土壤Cd污染值得关注。 相似文献
