Heavy metal contamination is a significant issue because of its common usage in many anthropogenic processes and subsequent release into environmental systems. There have been very few field studies located near lighters wharfs due to the absence of population and low concentration with comparing high level in residential area and industrial complex. In this study, investigation of metal contamination in shallow marine sediment around a lighters wharf, where small ships are anchored and repaired illegally, was conducted. The contamination levels of heavy metals were measured, enrichment factor (EF) was calculated, and statistical analysis of metal correlation was carried out. High metal contamination was observed in some samples, especially of Zn, Pb, and Cu. Additionally, the EF was more than 5 which is characterized as significant level of concern. Significantly high correlation between most metals may indicate that pollution originates from a commonly occurring source and subsequently accumulates. The possibility of anthropogenic pollution from the repairing of small ships has been implied.

韩国西南部打火机码头附近小型船舶沉积物中金属污染的评估

重金属污染是一个重要问题,因为它在许多人为过程中普遍使用并随后释放到环境系统中。由于人口稀少,集中度低,相对于住宅区和工业园区的高水平,很少有位于打火机码头附近的实地研究。在这项研究中,对打火机码头周围浅层海洋沉积物中的金属污染进行了调查,该码头是非法停泊和修理小型船只的地方。测定重金属污染水平,计算富集因子(EF),并进行金属相关性统计分析。在一些样品中观察到高金属污染,尤其是 Zn、Pb 和 Cu。此外,EF 超过 5,被认为是显着的关注度。大多数金属之间的显着高相关性可能表明污染源自常见的来源并随后累积。已经暗示了小船修理造成人为污染的可能性。
