Abstract

Heavy metal contamination in protected areas can cause sensitive ecosystems to be at risk. Bioindicators for monitoring heavy metal contamination need to be investigated. The objectives of this study were to determine heavy metal residues in soil in an urban area, and also lichens diversity. Twenty-two sampling plots of 1 km x 1 km size were selected in Nong Saeng sub-district, Pak Phli district in Nakhonayok province, Thailand. Lichens diversity was investigated, and soil samples were collected to analyze the amount of heavy metal residues in the soil. Afterwards, the potential ecological risk indexes (RI) and index of atmospheric purity (IAP) were presented. The results indicated that trace element concentrations in forest (For), urban (Urb) and agriculture (Agr) soils were not significantly different, and that land use type did not affect heavy metal contamination. However, two areas with high RI values of 358.27 and 483.76 were designated as being at considerable ecological risk. These values related to the lowest air quality index in distribution mapping of IAP. The relationship between index of atmospheric purity and potential ecological risk indexes (RI) of heavy metal accumulation in urban area implied that long-range transboundary air pollution may be a source of heavy metals contamination in some areas. The highest RI value related to Hg concentration in low land implied that it was possible that concentrations of heavy metals could have been affected by the discharge of wastewater into the low land, and especially in the study area that had acidic soil.
与城市重金属累积潜在生态风险指数(RI)相关的大气纯度指数(IAP)
保护区的重金属污染会使敏感的生态系统处于危险之中。需要研究监测重金属污染的生物指标。本研究的目的是测定城市地区土壤中重金属残留量和地衣多样性。在泰国Nakhonayok省Pak Phli区的Nong Saeng街道选择了22个1公里× 1公里大小的样地。研究地衣多样性,采集土壤样品,分析土壤重金属残留量。随后,给出了潜在生态风险指数(RI)和大气纯度指数(IAP)。结果表明:森林(For)、城市(Urb)和农业(Agr)土壤中微量元素含量差异不显著,土地利用类型对重金属污染没有影响。然而,两个RI值较高的地区(358.27和483.76)被指定为具有相当的生态风险。这些数值与IAP分布图中最低的空气质量指数有关。大气纯度指数与城市地区重金属积累潜在生态风险指数(RI)的关系表明,远距离跨境空气污染可能是某些地区重金属污染的来源之一。与低洼地区汞浓度相关的最高RI值表明,向低洼地区排放废水可能会影响重金属浓度,特别是在具有酸性土壤的研究地区。
