The study aimed to assess the environmental health impacts of the liquid waste from Assalaya Sugar Factory, the efficiency of the existing Assalaya effluent treatment plant, the dilution factors available in the White Nile to gather with wastewater environmental impacts. A descriptive cross-sectional focused on the Factory and its neighborhoods. Four hundred and thirty two out of 3931 households were statistically determined as the sample size, the individual samples were picked using multi-stage stratified method 432 households selected as sample size. Data were collected by using structured questionnaires, field observations, laboratory analysis and interviewing the concerned and affected persons. The effluent load discharged from the factory into the Al -jassir canal at the White Nile was analyzed for BOD, COD, pH, PO4, TDS, TSS, Turbidity, Color, and flow rate.The Data were processed by using the Statistical Package for Social Science (SPSS) version 16, Chi-square test, test associations and office excel 2007. The study showed that Eighty one percent of the households used the surplus irrigation canal as a source for water supply. 64% of the respondents suffered from diarrhea, vomiting and allergic diseases, the rather low rate of water consumption and the bad quality of water consumed were reflected adversely on hygiene and consequently increased water related diseases. The study concludes that always or sometime 49.5% of the water collectors were children and used animals and plastic containers for water collection and transportation. The conducted laboratory water analysis revealed that the average concentrations of PO4, COD and BOD of the raw wastewater produced by Assalaya Sugar Factory were 4260, 3800 and 1500 mg/l, respectively, these values were above the WHO recommended concentrations for the disposed treated effluent (2, 250 and 30 mg/L respectively). As to physical analysis; the turbidity on the average was higher (540 NTU) and the color was (854 TCU) also high.

Fish are valued as an ideal source of high-quality proteins, which contain large quantities of essential amino acids. The present investigation is designed to study the effect of intestinal helminths in the fish; Single, double and triple helminths infection on the protein content of fish Lethrinus mahsena in the presence of some heavy metals (HMs). In this study, total of 130 emperor fish were collected between November 2015 and May 2016 from the coast of Jeddah. The concentration of the HMs in the infected and uninfected fish was analyzed using the atomic flame absorption spectrometer. Total proteins were extracted from infected and uninfected fish tissues and separated by 12% of SDS-PAGE. The results revealed that individual cestodes and triple infection caused lower concentrations of As, Cd, Cu and Fe in fish tissues. While double lesions have caused a decrease in the concentration of Cd and Cu. There were no significant differences between the protein contents of infected and uninfected fish. This indicates that the presence of intestinal worms in the fortified intestine can reduce the harmful effect of accumulated HMs on the protein content of fish despite HMs contamination.
