海湾是脆弱的生态系统,通常位于人口稠密地区附近,有毒金属往往会积累并停留更长的时间。影响海洋生物。这项研究旨在调查汞引起的基于年龄的健康风险,Cd,Pb,和从爱琴海的两个主要海湾捕获的海底鱼类一样。为此,红乌鱼,whiting,吹笛者Gurnard,和浴缸gurnard,经常食用的物种,是从Saros和Edremit湾抓来的.从鱼的肌肉组织中确定有毒金属浓度。通过估计每周摄入量(EWI)进行健康风险评估,临时耐受每周摄入量(PTWI),目标危险商(THQ),总THQ(TTHQ),和目标致癌风险(TR)。埃德里米特湾的红乌鱼是有毒金属含量最高的物种,1.597mg/kg,0.041mg/kg,0.070mg/kg,汞为19.351毫克/千克,Cd,Pb,和作为,分别。来自Edremit湾的Whiting的汞和砷的平均浓度高于来自Saros湾的汞和砷的平均浓度。汞的含量,Pb,与在萨罗斯同一地点捕获的Pipergurnard(0.252、0.020和0.382mg/kg)相比,浴缸中的As(0.328、0.043和0.574mg/kg)更高。发现来自同一海湾的红鱼和白鲸的TTHQs>1,表明所研究的所有9个年龄段的潜在健康风险。另一方面,在前四个年龄类别中,萨罗斯湾所有物种的TTHQs被确定为>1,这可能会引发儿童和青少年的健康风险。根据Pb的TR指数,两个海湾的鱼都没有风险。然而,无机As的TR计算表明,在大多数年龄类别中,红色鱼和来自Edremit湾的白鲸的癌症风险很高。总而言之,结果显示,从Edremit湾捕获的鱼类对所有9个年龄组的汞和砷浓度构成严重的健康风险。在人口稠密的海湾中,监测和监测底鱼中的有毒金属含量以及基于种群的健康风险评估至关重要。
Bays are vulnerable ecosystems generally located near densely populated areas where toxic metals tend to accumulate and stay longer, affecting marine life. This study aimed to investigate the age-based health risks arising from Hg, Cd, Pb, and As in demersal fish captured from two major bays in the Aegean Sea. For this purpose, red mullet, whiting, piper gurnard, and tub gurnard, frequently consumed species, were caught from Saros and Edremit Bays. Toxic metal concentrations were determined from the muscle tissue of fish. Health risk assessments were conducted by the estimation of weekly intake (EWI), provisional tolerable weekly intake (PTWI), target hazard quotient (THQ), total THQ (TTHQ), and target carcinogenic risk (TR). Red mullet from Edremit Bay was the species with the highest toxic metal levels, which were 1.597 mg/kg, 0.041 mg/kg, 0.070 mg/kg, and 19.351 mg/kg for Hg, Cd, Pb, and As, respectively. Whiting from Edremit Bay had higher mean concentrations of Hg and As than those from Saros Bay. The levels of Hg, Pb, and As (0.328, 0.043, and 0.574 mg/kg) in the tub gurnard were higher in comparison with the piper gurnard (0.252, 0.020, and 0.382 mg/kg) caught in the same station in Saros. TTHQs of red mullet and whiting from the same bay were found to be > 1, indicating potential health risks for all nine age categories studied. On the other hand, TTHQs of all species from Saros Bay were determined to be > 1 for the first four age categories, which might trigger health risks for children and adolescents. According to the TR index for Pb, no risk was determined for the fish from both bays. However, TR calculations for inorganic As indicated high cancer risk in most of the age categories for red mullet and whiting from Edremit Bay. To sum up, the results revealed that the fish captured from Edremit Bay posed serious health risks in terms of Hg and As concentrations for all nine age categories. Surveillance and monitoring of toxic metal levels in demersal fish and population-based health risk evaluation are vital in heavily populated bays.
