TSP concentrations in ambient air and dry deposition were measured at an (agricultural) sampling site in Taiping. The TSP concentrations are compared with those in the other counties in Asia. Statistical differences between the TSP concentrations and dry depositions in Luliao district (mixed site) and Taiping district (agricultural site) are discussed. Ambient air particulate-bound mercury Hg(p) concentrations in TSP and dry depositions are analyzed and discussed. Mean concentrations and dry depositions of Hg(p) were tested at two characteristic sampling sites – Luliao (mixed) and Taiping (agricultural) districts. Finally, the measured ambient air particulate-bound mercury Hg(p) concentrations and dry depositions were compared with those in other regions of the world. TSP concentrations were highest in March at 49.7 (μg/m3) and lowest in June at 15.85 (μg/m3). Dry deposition was highest in March at 1336.41 (μg/m2*min) and lowest in June at 15.85 (μg/m2*min). The highest average dry depositions and TSP concentrations were measured in March. The particulate-bound mercury Hg(p) concentrations in TSP were higher at the Luliao sampling site (0.384 μg/m3) than at the Taiping (0.078 μg/m3) sampling site. The mean Hg (p) dry deposition was higher in Taiping (0.665 μg/m2*min) than in Luliao (0.387 μg/m2*min). The mean concentrations of TSP differed between Luliao (mixed) and Taiping (agriculture) sampling sites, but the mean dry depositions did not. The differences between TSP concentrations and dry depositions might have arisen from the fact that most of the particulate-bound mercury Hg(p) at the Taiping (agriculture) sampling site had natural sources while that at the Luliao (mixed) sampling site had anthropogenic sources. The average ratios of highest to lowest particulate concentrations exceeded seven in urban areas; exceeded 1.5 in areas of traffic, and approached (one OR unity OR 1) for all particulate sizes.

混合和农业(MA)地点周围的颗粒状结合汞Hg(p)浓度,组成和干沉降研究

在太平的(农业)采样点测量了环境空气中TSP的浓度和干沉降。将TSP浓度与亚洲其他县的浓度进行比较。讨论了芦lia地区(混合区)和太平区(农业区)的TSP浓度和干沉降之间的统计差异。分析和讨论了TSP和干燥沉积物中与环境颗粒结合的汞Hg(p)的浓度。在两个典型的采样点-芦lia(混合)和太平(农业)区测试了Hg(p)的平均浓度和干沉降。最后,将测得的与环境空气颗粒结合的汞Hg(p)浓度和干燥沉积物与世界其他地区的浓度进行了比较。三月份TSP浓度最高,为49.7(μg/ m 3),最低的是6月的15.85(μg/ m 3)。3月份干沉降最高,为1336.41(μg/ m 2 * min),6月份最低为15.85(μg/ m 2 * min)。三月份测量了最高的平均干沉降和TSP浓度。在TSP的颗粒团汞汞(P)的浓度在Luliao采样点(0.384微克/米均高于3)比在太平(0.078微克/米3)的采样点。太平(0.665μg/ m 2 * min)的平均Hg(p)干沉降高于卢廖(0.387μg/ m 2*分钟)。芦辽(混合)和太平(农业)采样点之间的TSP平均浓度有所不同,但平均干沉降没有差异。TSP浓度与干沉降之间的差异可能是由于以下事实造成的:太平(农业)采样点的大多数与颗粒结合的汞Hg(p)都是自然来源,而芦lia(混合)采样点的汞是人为来源。在城市地区,最高和最低微粒浓度的平均比率超过了七;流量区域超过1.5,并针对所有微粒尺寸均接近(一或一或一)。
