Abstract

Concentrations of some metals were determined in muscle tissue of five marine fish species (Engraulis encrasicolus, Sarda sarda, Mullus barbatus, Trachurus mediterraneus, and Merlangius merlangus) caught from the Eastern Black Sea coast of Turkey in 2017. Heavy metals were analyzed by using inductively coupled plasma-optical emission spectrometry after the muscle tissues of fish were digested by acids. The metal accumulation differences between species were investigated statistically. The levels of aluminum, cadmium, chromium, copper, iron, manganese, lead, and zinc in the muscles of fish were 3.27, 0.12, 0.27, 2.04, 9.97, 1.00, 0.95, and 10.65 µg/g, respectively. The highest levels of aluminum, cadmium, chromium, and manganese were detected in E. encrasicolus; the highest levels of lead and zinc were accumulated in T. mediterraneus and the highest concentration of iron and copper was found in S. sarda. The average lead concentration values were found to be above the limit values determined by national and international standards due to anthropogenic inputs such as mining activities and agricultural wastes. In addition, potential risks associated with human consumption were evaluated using quality indices such as estimated daily intake and target hazard ratio. According to these indexes, a potential risk in terms of human health has not been identified due to consuming fish tissues.

土耳其黑海东部沿岸部分商业鱼类可食用组织中的重金属浓度及健康风险评估

摘要

在五种海洋鱼类(Engraulis encrasicolusSarda sardaMullus barbatusTrachurus mediterraneusMerlangius merlangus )的肌肉组织中测定了某些金属的浓度。) 于 2017 年从土耳其黑海东部沿岸捕获。 鱼的肌肉组织被酸消化后,采用电感耦合等离子发射光谱法分析重金属。统计研究了物种之间的金属积累差异。鱼肌肉中铝、镉、铬、铜、铁、锰、铅、锌的含量分别为3.27、0.12、0.27、2.04、9.97、1.00、0.95和10.65μg/g。在E. encrasicolus中检测到的铝、镉、铬和锰含量最高;在T. mediterraneus中积累了最高水平的铅和锌,在S. sarda 中发现了最高浓度的铁和铜. 由于采矿活动和农业废物等人为投入,平均铅浓度值高于国家和国际标准确定的限值。此外,使用质量指标(例如估计的每日摄入量和目标风险比)评估与人类消费相关的潜在风险。根据这些指标,尚未确定食用鱼类组织对人类健康造成的潜在风险。
