Background: Fish, a widely claimed healthy food for humans, could also pose problems to health due to accumulation of pollutants, especially heavy metals and pesticides. Since the world's fish stocks are limited due to overfishing, degraded freshwater, and pollution from various sources, the government proposed farmed fish which is one of the fastest growing food production sectors as an alternative. The objective of this study was to investigate the effects of tilapia or Mugil cephalus fish diets obtained from polluted areas on male reproductive hormones and prolactin. A total of 80 male Wister albino rats having an average weight of 130-150 g at the beginning of the experiment were used. They were divided into control group and seven treated groups which received the following doses that increased monthly according to the increase in rat body weight (b.w.). The treated groups received 200 g/70 kg human b.w. which is equivalent to 0.4 g/140 g rat b.w., 0.63 g/220 g rat b.w., and 0.83 g/291 g rat b.w. of tilapia fish (wild and farmed freshwater and brackish water) or Mugil cephalus fish (farmed freshwater and brackish water and wild marine water) daily for 3 months then were left on AIN-93M diet and purified water ad libitum. Results: The present results demonstrated that tilapia and Mugil cephalus fish diets caused decrease in serum total testosterone, follicle-stimulating hormone, luteinizing hormone, and sperm count, while sperm abnormalities significantly increased. Also, significant elevation of serum prolactin was observed in male rats fed with the same diets except wild brackish water tilapia fish and farmed freshwater and brackish water Mugil cephalus fish diets which showed a decrease. However, tilapia and Mugil cephalus fish diets had no effect on serum 17β-estradiol. The histopathological studies confirmed biochemical data as less dense packing of spermatogenic cell of the seminiferous tubules with reduction in the number of sperms in lumen of the epididymal tubules. Conclusions: These results may indicate that consumption of tilapia and Mugil cephalus fish diets from polluted areas has adverse effects on male reproductive hormones and prolactin in male albino rats.

“…However, only 14 to 20 individual PAHs are of regulatory and research interests [11]. Various governmental and non-governmental organizations, such as the United States Environmental Protection Agency (USEPA) and Greenpeace [27], are actively involved in monitoring these pollutants. USEPA established 16 PAHs as priority pollutants for monitoring in the environment [28][29][30].…”

This review paper presents a comprehensive synthesis of current knowledge on the contamination of water systems by polycyclic aromatic hydrocarbons (PAHs). PAHs, organic contaminants characterized by two or more fused aromatic rings, are notably problematic due to their persistence, bioaccumulation, and significant health risks. The review commences with an examination of various sources of PAHs in aquatic environments, encompassing both anthropogenic activities, such as industrial discharges, urban runoff, and oil spills, and natural phenomena including volcanic eruptions and wildfires. Subsequently, the discussion shifts to the distribution patterns of PAHs within different aquatic ecosystems, with an analysis of factors that influence their transport. Considerable focus is placed on the entry mechanisms of PAHs into water systems and their interactions with diverse environmental matrices. Additionally, the ecotoxicological effects of PAHs on aquatic life are scrutinized, with particular emphasis on molecular, individual, and ecosystemic impacts. This includes an exploration of PAH bioaccumulation in aquatic organisms and their potential mutagenic and carcinogenic consequences. The review further addresses the challenges associated with detecting and quantifying PAHs in aquatic settings, reflecting on the advancements in analytical methodologies and the complexities introduced by their varied physicochemical properties. The paper concludes with a summary of existing regulatory frameworks and guidelines governing PAH contamination in water systems, underscoring the imperative for global collaboration in the monitoring and management of PAH pollution.
