Abstract

Data on polycyclic aromatic hydrocarbons (PAHs) measured in surface sediment and cores in the New York/New Jersey Harbour under the Contamination Assessment and Reduction Project (CARP) was examined via Positive Matrix Factorization (PMF), which revealed six sources. Two represented the higher and lower molecular weight (MW) fractions of coal tar and/or creosote (pyrogenic) sources and explained 49% of PAH mass in the sediment samples. Two sources were related to uncombusted petroleum (petrogenic) sources, such as heavy fuel oil and crude oil, and explained 30% of PAH mass. The final two sources were related to combustion (pyrogenic) sources such as gasoline‐ and diesel‐fuelled vehicles and explained 21% of the PAH mass. Sediment cores revealed that Σ22PAH increased from the pre‐industrial period until about 1980 and then decreased because of efforts to control water pollution via mechanisms such as the Clean Water Act.

纽约/新泽西港沉积物中多环芳烃的来源分析

采用正矩阵分解法(PMF)对纽约/新泽西港表层沉积物和岩心中多环芳烃(PAHs)的污染评估与减少项目(CARP)数据进行了分析，发现了6个污染源。两个代表较高和较低分子量(MW)的煤焦油和/或杂酚油(热原)来源，并解释了49%的沉积物样品中的多环芳烃质量。两个来源与未燃烧的石油(产岩)来源有关，如重质燃料油和原油，解释了30%的多环芳烃质量。最后两个来源与燃烧(热原)来源有关，如汽油和柴油燃料的车辆，并解释了21%的多环芳烃质量。沉积物岩心显示，Σ22PAH从前工业化时期到1980年左右增加，然后由于通过《清洁水法》等机制控制水污染的努力而减少。

期刊介绍： Water and Environment Journal is an internationally recognised peer reviewed Journal for the dissemination of innovations and solutions focussed on enhancing water management best practice. Water and Environment Journal is available to over 12,000 institutions with a further 7,000 copies physically distributed to the Chartered Institution of Water and Environmental Management (CIWEM) membership, comprised of environment sector professionals based across the value chain (utilities, consultancy, technology suppliers, regulators, government and NGOs). As such, the journal provides a conduit between academics and practitioners. We therefore particularly encourage contributions focussed at the interface between academia and industry, which deliver industrially impactful applied research underpinned by scientific evidence. We are keen to attract papers on a broad range of subjects including: -Water and wastewater treatment for agricultural, municipal and industrial applications -Sludge treatment including processing, storage and management -Water recycling -Urban and stormwater management -Integrated water management strategies -Water infrastructure and distribution -Climate change mitigation including management of impacts on agriculture, urban areas and infrastructure
