Suez gulf is the important region not only in Egypt but also around the world, because it is a vital location in connecting Red Sea with Mediterranean Sea through Suez Canal. Due to this nature in shipping ports, loading and unloading activities, gulf water is the most exposure to petrochemical pollution than other sea water. Not only petrochemical pollution can affect on gulf pollution but also chemical plants can be affected. Surface sea water samples at this study are collected from 7 sites from electricity location to hard steel company in attaqa road, including sewage co. The objective of this study is the monitoring of the contamination of water by petrochemical and chemical pollution from loading and unloading of ships in harbor and by different industrial chemical plants, navigation and recreation activities. This study includes physical and chemical parameters of water such as pH, conductivity, salinity, TDS, TSS, TS, DO, BOD, COD and total alkalinity. These parameters were studied seasonally to ensure that the gulf water was contaminated by all these activities in the gulf region and the effect of these pollutants in biota. This analysis has been achieved by field and laboratory studies. and the data was collected from official and previous researches.
