Abstract

Abstract The results of this investigation show that Azerbaijan industries and agricultural sector provide considerable anthropogenic impact on the environment of Caucasus. The use of moss biomonitoring technique and neutron activation analysis (NAA) is a first attempt to study heavy metal atmospheric deposition in Azerbaijan, a country different relief and climate. The study was undertaken in the summer of 2015 of atmospheric deposition of man-made heavy metal pollutants in the area of mining and processing plant in Gadabay and Dashkasan mininig district. At the same time samples were collected from the Goygol State Reserve in the Lesser Caucasus not far from the city of Ganja. A total 85 moss samples (predominantly Pleurozium schreberi) collected in both environmentally contrast area. Elemental determination was carried out by epithermal neutron activation analysis (ENAA) at the reactor IBR-2 of Joint Institute for Nuclear Research (FLNP JINR). For the first time 44 elemental concentrations were determined (Na, Mg, Al, Si, Cl, K, Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Br, Rb, Sr, Mo, Ag, Cd, In, Sb, I, Cs, Ba, La, Ce, Nd, Sm, Eu, Tb, Tm, Yb, Hf, Ta, W, Au, Th, U). Multivariate statistical analysis of the analytical results obtained will make it possible to identify the main sources of pollution and to assess the role of long-range transport of pollutants.

基于苔藓技术和中子活化分析的阿塞拜疆重金属大气沉降研究
调查结果表明,阿塞拜疆工业和农业部门对高加索地区的环境造成了相当大的人为影响。利用苔藓生物监测技术和中子活化分析(NAA)对不同地形和气候的阿塞拜疆进行重金属大气沉降研究是首次尝试。本研究于2015年夏季对嘎达拜和大喀山矿区采矿和加工厂区域大气中人为重金属污染物的沉积进行了研究。同时,在离Ganja市不远的小高加索地区的Goygol国家保护区采集了样本。在两个环境对比区共采集了85份苔藓样品(主要是白蜡苔藓)。元素的测定采用超热中子活化分析法(ENAA)在联合核科学研究所IBR-2反应堆进行。首次44元素浓度的测定(钠、镁、铝、硅、氯、钾、钙、Sc, Ti, V,铬、锰、铁、有限公司镍、铜、锌、,,Br, Rb, Sr,密苏里州,Ag)、Cd,某人,我,Cs,英航,洛杉矶,Ce、Nd, Sm,欧盟、结核病、Tm, Yb,高频,助教,W,非盟,Th, U)。多元统计分析的分析结果将有可能识别的主要污染源和污染物评估远程运输的作用。
