Contaminated sediments at a pulp mill and former chor-alkali effluent treatment facility in Nova Scotia, Canada will undergo remediation. However, baseline studies assessing contaminants in marine biota in the marine receiving environment are lacking. Historical qualitative and quantitative contaminant data in biota from Boat Harbour (a former tidal lagoon which was used to treat industrial effluent since 1967), and surrounding marine environment were reviewed to establish baseline pollution from industrial effluent and contaminated sediments. Elevated metal, dioxins and furan concentrations previously measured in marine biota needs updating to help inform pre-remediation monitoring. Selection of species, contaminants of concern and sampling locations were ad hoc and often inconsistent with environmental effects monitoring requirements under Canadian federal Pulp and Paper Effluent Regulations. These consolidated baseline data are required to determine historical impacts and to assist future monitoring during Boat Harbour sediment remediation to compare against.
加拿大新斯科舍省一家纸浆厂和前氯碱废水处理厂的受污染沉积物将进行修复。然而，缺乏对海洋接收环境中海洋生物体内污染物的基线研究。对 Boat Harbour（自 1967 年以来用于处理工业废水的前潮汐泻湖）和周围海洋环境中的生物群历史定性和定量污染物数据进行了审查，以确定工业废水和受污染沉积物造成的基线污染。需要更新以前在海洋生物体内测量到的金属、二恶英和呋喃浓度，以帮助为预修复监测提供信息。选定的物种、关注的污染物和采样地点都是临时性的，而且往往不符合加拿大联邦纸浆和造纸废水法规规定的环境影响监测要求。需要这些综合基线数据来确定历史影响，并在 Boat Harbour 沉积物修复期间协助未来监测，以便进行比较。
