Abstract

The present study was carried out to assess the occurrence and ecological risk assessment of 16 priority polycyclic aromatic hydrocarbons (PAHs) in the Budhabalanga river estuary and coastal stretch of Chandipur. The range of PAH concentration varied between 19.5 and 1206 ng L^-1. The ecological risk assessment of individual PAHs and ∑PAHs was calculated using the risk quotient and toxic equivalency factor method. Low molecular weight PAHs contributed towards ecological risk burden in comparison to high molecular weight PAHs. PAH diagnostic ratio suggested the presence of both pyrolytic and petrogenic origin for the observed PAHs. Pearson correlation and PCA plot clearly show interdependency between all PAHs and stations sampled.

印度东海岸昌迪普尔布哈巴兰加河河口地表水中多环芳烃的赋存及风险评价

对布哈巴兰加河河口及昌迪普尔沿海段16种重点多环芳烃（PAHs）的赋存状况及生态风险评价进行了研究。多环芳烃浓度变化范围为19.5 ~ 1206 ng L-1。采用风险商法和毒性等效因子法计算各PAHs和∑PAHs的生态风险评价。与高分子量多环芳烃相比，低分子量多环芳烃对生态风险负担的贡献更大。多环芳烃诊断比值提示多环芳烃既有热解成因，也有岩源成因。Pearson相关和PCA图清楚地显示了所有多环芳烃与采样台站之间的相互依赖性。

期刊介绍： This journal is devoted to publishing the highest quality innovative papers in the fields of biochemistry and biotechnology. The typical focus of the journal is to report applications of novel scientific and technological breakthroughs, as well as technological subjects that are still in the proof-of-concept stage. Applied Biochemistry and Biotechnology provides a forum for case studies and practical concepts of biotechnology, utilization, including controls, statistical data analysis, problem descriptions unique to a particular application, and bioprocess economic analyses. The journal publishes reviews deemed of interest to readers, as well as book reviews, meeting and symposia notices, and news items relating to biotechnology in both the industrial and academic communities. In addition, Applied Biochemistry and Biotechnology often publishes lists of patents and publications of special interest to readers.
