Abstract

Air pollution is a major environmental problem in Indonesia. Potentially toxic elements (PTEs) which bounded to particulate matter (PM) samples were collected from Maros karst area, the second largest karst in the world. The seasonal levels of PTEs and ecological risk assessment were used to investigate the pollution levels near the residential areas using pollution load index (PLI) and potential ecological risk index (PERI). Spatial distributions of ecological risks based on the PTEs concentration have been explored with Empirical Bayesian Kriging method. The result indicated the mean concentration of PTEs (Cr, Pb, Cu, As and Zn) were significantly higher in dry season than wet season. Based on the PERI and PLI values, the PTEs accumulation are more severe near industrial activities and traffic roads. Hotspots of the PTEs were located in the East and Southeast area. The implications of this study could be used to optimize the management strategies in controlling the PTEs pollution and become a scientific reference for taking environmental protection policies

印度尼西亚马洛斯县潜在有毒元素的空间分布和生态风险

空气污染是印度尼西亚的一个主要环境问题。从世界第二大喀斯特Maros喀斯特地区采集了与颗粒物（PM）样品结合的潜在有毒元素（PTEs）。利用PTEs的季节水平和生态风险评估，利用污染负荷指数（PLI）和潜在生态风险指数（PERI）调查居民区附近的污染水平。采用经验贝叶斯克里格方法探讨了基于PTEs浓度的生态风险的空间分布。结果表明，PTEs（Cr、Pb、Cu、As和Zn）的平均浓度在旱季显著高于雨季。根据PERI和PLI值，PTEs在工业活动和交通道路附近的积累更为严重。PTE的热点位于东部和东南部地区。本研究的启示可用于优化PTEs污染控制的管理策略，并为制定环境保护政策提供科学参考
