2005年3月至5月，对韩国安山市半壁工业园区（BWIC）某高度工业化地区的总气态汞（TGM）浓度及其相关环境参数进行了测定。整个研究期间测量的汞平均浓度计算为6.32±8.56ngm - 3（范围为2.32-181ngm - 3； N=1160）。由于强烈的人为活动的影响，显著的高汞浓度水平（例如，达到或高于10ngm−3）约占所有数据的7.5%，平均值为21.8±26.3ngm−3（N=87）。通过将数据分为白天和夜间，Hg值表现出明显的白天增强，这可能是由于工作时间强烈的人为活动造成的。相关性分析结果表明，Hg浓度与温度以及几种污染物（如no2和NOx）之间可能存在关系。对与气团输送模式有关的汞数据的评估证实，该工业区的汞浓度水平最显著地受到当地污染源的影响，而不是远处污染源。
The concentrations of total gaseous mercury (TGM) and its relevant environmental parameters were measured at a highly industrialized area in the Ban Wall industrial complex (BWIC) in An San city, Korea from March to May 2005. The mean concentrations of Hg measured during the entire study period were computed to be 6.32±8.56ngm−3(range of 2.32–181ngm−3; N=1160). Due to the effects of strong man-made activities, the significantly high Hg concentration levels (e.g., at or above 10ngm−3) comprised about 7.5% of all data with the mean of 21.8±26.3ngm−3(N=87). By separating the data into daytime and nighttime periods, the Hg values exhibited a notable daytime enhancement possibly due to strong man-made activities during working hours. The results of the correlation analysis indicated the possible relationship between the Hg concentration and the temperature as well as several pollutant species (e.g., NO2and NOx). Evaluation of the Hg data in relation with the air mass transport pattern confirms that the Hg concentration levels in this industrial area are affected most eminently by local, rather than distant, pollution sources.
