Abstract

This study was conducted to analyze well waters in seven regions, Hajar, Mughynia, Nuweiba, Rabigh, Al-Abwa, Mastourah, and Kilayyah, which lie along the valleys that discharge in the Red Sea in the Western Region of Saudi Arabia. This is to evaluate and determine whether the water of these wells is suitable for drinking and agricultural use. The study included determination of the major elements Ca, Na, K, Mg, P, F, the heavy metals, Fe, Cu, Zn, Al, Mn, Ba, and the toxic metals, Ni, Pb, Cd, Cr, Ag, Mo, Co, Be, V, Ar, Sb, Ti, and U concentration in the water of these wells. The elements Na, K, P increased in the ground water following the passage of water from upper valley to lower valley, and the elements Ca, Na, Mg and Cl concentration in well water is affected by their nearness to the Red Sea water, and the wells of Hajar, El-nugemia and Nuweiba have the least concentrations of these elements while those near the coast, Mastourah, Rabigh, Kilayyah and Al-Abwa contain water with high concentrations of these elements. As for water content of the major elements, all well waters is acceptable for drinking, except Mastourah with a high concentration of Na and Mg, and Rabigh and Al-Abwa with a high concentration of Ca. All wells water is acceptable for drinking as regards their content of the heavy and toxic metal.

Abstract

A comparative evaluation of the heavy metals Arsenic, Lead, Cadmium, Chromium, Copper and Zinc in versatile water resources in Egypt and Saudi Arabia was conducted during the summer of 2015. All the studied water brands contained markedly scarce amounts of Arsenic, which was under the limit of detection. Chromium was also found to be under the limit of detection in Baraka, Nestle Pure Life, Hayat, Aman Siwa and Siwa from the water market at Mansoura (Egypt). Similar finding was recorded for Cadmium in Aman Siwa and Lead in Hayat, Aman Siwa and Siwa water brands. The highest levels of Cadmium, Chromium, Copper, Lead and Zinc were recorded in Baraka, Aquafina, Dasani, Safi and Aquafina water brands, respectively. However, the lowest amounts of these metals were detected in Siwa, Safi, Safi, Nestle Pure Life and Aman Siwa, respectively. Ablution water showed undesirable amounts of Zinc (0.25 ppm). Street coolers recorded relatively low amounts of Chromium (0.09 ppm) and Zinc (0.10 ppm). Zamzam water was free of Cadmium, Lead and Zinc, however it recorded low amounts of Copper (0.004 ppm) and undesirable levels of Chromium (0.13 ppm). The level of Chromium detected in the purified River Nile’s water was 0.125 in the tap water and 0.110 ppm in vending machines. On the other hand, the amounts of Zinc were 0.085 and 0.546 ppm in the two water brands, respectively. The heavy metal analysis provided insight into the quality of water sources under investigation. The study discussed the effects of heavy metals on the human health and their effects on the community health in the long term. The study reviewed future aspirations for the management of water resources in Egypt and Saudi Arabia.

Abstract

The present study was conducted randomly at El Mekhwah Province, Kingdom of Saudia Arabia to determine the prevalence of the intestinal protozoa and Helminth parasites during 2013-2014. Examination of 210 stool samples revealed that 16.19% of the visitors harbored intestinal protozoa, the most common parasites found were Entamoeba histolytica (6.19%), Entamoeba coli (6.66) and Giardia lambia (3.33%) While investigation of 300 stool samples for parasitic helminthes showed that 31 (10.33) were infected with Hymenolips nana, (4.33%) for Ascaris lumbricoides 4% and 2% for Taenia saginata.
