Abstract

In this study, it was aimed to determine the effect of sound and light pollution on Zebra mussel (Dreissena polymorpha) by biomarker and nutritional composition. For this purpose, an experimental design was carried out in laboratory conditions where the model was exposed to live sound, light, and combined sound + light parameters for 30 min every hour over 96 h. Changes in the biomarkers superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx) activities, as well as glutathione (GSH) and thiobarbituric acid (TBARS) levels, were assessed in the model organism exposed to sound, light, and sound + light pollution. The changes in protein and fat amounts were determined. When the changes in biomarkers were examined statistically compared to the control, there was no significant decrease in SOD activity (p < 0.05), a significant increase in CAT activity in sound and sound+light, but a significant decrease in light (p < 0.05), no significant difference in GPx activity (p > 0.05). It was determined that there was a significant increase in GSH and TBARS levels in all three parameters. Significant changes were also observed in the proximate composition. As a result, exposure to sound, light and sound+light pollution caused an increase in oxidative damage and decreases in protein and lipid composition were detected.

光污染和噪声污染对多甲鱼氧化应激和近似成分的影响

本研究旨在通过生物标志物和营养成分研究声光污染对斑马贻贝（Dreissena polymorpha）的影响。为此，在实验室条件下进行了实验设计，将模型暴露于声、光和声+光组合参数下，每小时30分钟，持续96小时。评估暴露于声、光和声+光污染的模型生物中生物标志物超氧化物歧化酶（SOD）、过氧化氢酶（CAT）和谷胱甘肽过氧化物酶（GPx）活性以及谷胱甘肽（GSH）和硫代巴比妥酸（TBARS）水平的变化。测定了蛋白质和脂肪含量的变化。与对照组相比，对生物标志物的变化进行统计学检查时，SOD活性无显著降低(p <；0.05)，声光组CAT活性显著升高，声光组CAT活性显著降低(p <；0.05)， GPx活性差异不显著(p >；0.05)。结果表明，在所有三个参数中，谷胱甘肽和TBARS水平均显著升高。在近似组成中也观察到显著的变化。结果表明，声、光和声+光污染均引起氧化损伤增加，蛋白质和脂质组成降低。
