Polyaromatic hydrocarbons are highly stable and can easily permeate through biological membranes due to their lipophilic nature. They are characterized by their ability to act at the site of application and even at sites distant to the zone of application. Any contamination associated with aquatic bodies due to the presence of PAHs can be assessed by investigating biochemical changes. The most common polycyclic aromatic hydrocarbon (PAH) pollutant naphthalene was selected for the bioassay experiment using Indian climbing perch Anabas testudineus. The biochemical response in the muscle tissue was investigated after exposure to varying concentrations of naphthalene by estimating protein, glycogen, Alanine Aminotransaminase, and Aspartate Aminotransaminase. The results showed inhibition of protein and glycogen levels due to naphthalene stress. Similarly, a decrease in the activity of transaminase in muscle tissues was noticed. The results have been computed using star plots for interpretation of integrated biomarker response (IBR). The results clearly support the role of biochemical parameters in assessing the impact of naphthalene stress on fish health. IBR index can be developed as a useful tool in monitoring quantitative as well as the qualitative effect of naphthalene toxicity in fishes and other aquatic animals.

综合生物标志物反应工具在评估Anastas testudineus萘毒性中的作用
聚芳族烃具有高度的稳定性,并且由于其亲脂性,因此很容易透过生物膜。它们的特征在于它们在施用部位甚至远离施用区域的部位起作用的能力。由于存在PAHs,与水体相关的任何污染都可以通过调查生化变化来评估。使用印度攀爬鲈Anabas testudineus选择了最常见的多环芳烃(PAH)污染物萘进行生物测定实验。暴露于不同浓度的萘后,通过估算蛋白质,糖原,丙氨酸氨基转氨酶和天冬氨酸氨基转氨酶,研究了肌肉组织中的生化反应。结果显示由于萘胁迫而抑制蛋白质和糖原水平。同样,发现肌肉组织中转氨酶的活性降低。已经使用星图计算了结果,以解释综合生物标志物反应(IBR)。结果清楚地支持了生化参数在评估萘胁迫对鱼类健康的影响中的作用。可以将IBR指数开发为监测萘在鱼类和其他水生动物中的定量以及定性作用的有用工具。
