Abstract

This study aimed to detect the actual levels of phenol and nonylphenoethoxylate 9 (NPEO 9) in some freshwater courses and muscles of the Niltilapia, Oreochromis niloticus, in three different Egyptian Governorates (AlGiza, El-Dakahlya and Port-Said). Moreover, the ecological and probabilitof public health risks were evaluated for 6 sites in the three governoratesResults revealed that all the detected levels of phenol and those of totainvestigated compounds in water were above the reported permissibllimits. Phenol had medium ecological risk in water at all sampling siteduring the study period except in El-Mataria City at El-Dakahlya (LakManzala), where a high ecological risk was recorded. Meanwhile, higlevels of ecological risk of NPEO 9 were observed in all water samplecollected from the six investigated sites during the four seasons of the studperiod. In addition, the calculated hazard index (HI) for investigatephenolic compounds indicated high non-cancer risks for generalizehabitual consumers at all sites during different seasons. © 2022, Egyptian Society for the Development of Fisheries and Human Health.
