Abstract

Concentrations of polychlorinated biphenyls (PCBs) and polychlorinated dibenzo-p-dioxins and furans (PCDD/Fs) were measured in imported canned fish such as mackerel, sardine and tuna to evaluate the risk relating to human consumption of these products. Gas chromatography-mass spectrometry (GC/MS) was used to evaluate the concentrations of PCBs and PCDD/Fs in the samples. The $\sum$ 28 PCB concentrations in the canned mackerel, tuna and sardine ranged from 0.33 to 9.48 ng g ^-1, -1 and -1, respectively, while the $\sum$ 14 PCDD/Fs concentrations varied from 0.06 to 4.70 ng g^-1 for mackerel, 0.72 to 9.43 ng g^-1 for tuna and not detected to 22.0 ng g ^-1 for sardines. Health risk analysis suggests that ingestion of these samples could lead to adverse non-carcinogenic and carcinogenic risks over a lifetime.

尼日利亚进口罐头鱼中的多氯联苯、多氯二苯并对二恶英和呋喃及风险评估。

测量了鲭鱼、沙丁鱼和金枪鱼等进口罐头鱼类中多氯联苯(PCBs)和多氯二苯并对二恶英和呋喃(PCDD/Fs)的浓度，以评估人类食用这些产品的风险。采用气相色谱-质谱法(GC/MS)测定样品中PCBs和PCDD/Fs的浓度。鲭鱼、金枪鱼和沙丁鱼罐头的∑28 PCB浓度分别为0.33 ~ 9.48 ng g-1、-1和-1，鲭鱼罐头的∑14 PCDD/Fs浓度为0.06 ~ 4.70 ng g-1，金枪鱼罐头的∑14 PCDD/Fs浓度为0.72 ~ 9.43 ng g-1，沙丁鱼罐头的∑14 PCDD/Fs浓度为22.0 ng g-1。健康风险分析表明，摄入这些样品可能导致终生不良的非致癌和致癌风险。

期刊介绍： Food Additives & Contaminants: Part B publishes surveillance data indicating the presence and levels of occurrence of designated food additives, residues and contaminants in foods, food supplements and animal feed. Data using validated methods must meet stipulated quality standards to be acceptable and must be presented in a prescribed format for subsequent data-handling. Food Additives & Contaminants: Part B restricts its scope to include certain classes of food additives, residues and contaminants. This is based on a goal of covering those areas where there is a need to record surveillance data for the purposes of exposure and risk assessment. The scope is initially restricted to: Additives - food colours, artificial sweeteners, and preservatives; Residues – veterinary drug and pesticide residues; Contaminants – metals, mycotoxins, phycotoxins, plant toxins, nitrate/nitrite, PCDDs/PCFDs, PCBs, PAHs, acrylamide, 3-MPCD and contaminants derived from food packaging. Readership: The readership includes scientists involved in all aspects of food safety and quality and particularly those involved in monitoring human exposure to chemicals from the diet. Papers reporting surveillance data in areas other than the above should be submitted to Part A . The scope of Part B will be expanded from time-to-time to ensure inclusion of new areas of concern.
