Recent studies have shown that many persistent organic pollutants (POPs, e.g., polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs) and various pesticides), are strongly associated with carbonaceous materials (including organic carbon (OC) and black carbon (BC)). We hypothesize that carbonaceous materials can be used as a first-order pollution index, to indicate areas where POP pollution may require further investigation. We tested our hypothesis and found that strong, positive correlations between BC and OC contents versus the concentrations of PCBs (and PAHs) existed in estuarine sediments of the Danshui River in 2005 and 2008. Thus, our preliminary results demonstrate that POC and BC are potential indicators of the POP pollution potential in fluvial sediments of the Danshui River in Taiwan. This innovative approach can provide a simple, relatively inexpensive and expedient means to monitor concentrations of POPs in polluted aquatic sediments of Taiwan, and/or those having a legacy of POP inputs.
最近的研究表明，许多持久性有机污染物（POPs，如多氯联苯（PCBs）、多环芳烃（PAHs）和各种农药）与碳质材料（包括有机碳（OC）和黑碳（BC））密切相关。我们假设碳质材料可用作一级污染指标，以指示可能需要进一步调查的 POP 污染区域。我们检验了这一假设，发现 2005 年和 2008 年淡水河流域河口沉积物中存在黑碳和有机碳含量与 PCBs（和 PAHs）浓度之间存在强烈的正相关关系。因此，我们的初步结果表明，POC 和 BC 是台湾淡水河河流沉积物中 POP 污染潜力的潜在指标。这种创新方法可以为监测台湾受污染水下水体沉积物中 POPs 的浓度，以及/或那些具有 POP 输入历史的地区，提供一种简单、相对廉价和便捷的方法。
