El-Salam canal is a potential project reusing the Nile Delta drainage water for Sinai desert agriculture: Microbial and chemical water quality

Heavy Metal Pollution Investigation of Left Bank Outfall Drain of Coastal District Badin, Sindh, Pakistan by Using Arc GIS

“…It is obvious that the concentration of iron was higher near entrance of drain and it reduced on reaching the coastal sea water mixing zone (Fig 8). It may be due to high quantity of water near coast, causing heavy metal concentration get diluted.Iron concentration in all the sampling areas was also within permissible limits of FAO (5 mg/L) for agriculture use [18].The results of the concentration of Fe are in agreement with Saif et al [17].Similar findings were also reported by Tariq et al [19] and Ali et al [24].…”

“…Zinc was within permissible limits (5 mg/L) of NEQS in all the sampling areas. Same reducing pattern of Zinc concentration was found as water quantity increased near coastal mixing zone (Fig 1).Zinc concentration in all the sampling areas was also within permissible limits of FAO (2 mg/L) for agriculture use [18].Similar results for zinc concentration were also found by [17,19,24].It has been reported that exceeded concentration of zinc in water bodies, causes fever, depression, malaise, cough, vomiting and headache [25,26].…”

“…Copper was found to be within range (1 mg/L) ofNEQS for industrial effluents, of sampling areas.The result of copper concentration was ranged from0.002-0.267 mg/L .It is obvious in figure that the concentration of copper was higher near entrance path of mega drains and it reduced on reaching the coastal sea water. The concentration of copper in all the sampling areas except S-2 and S-8 was found within permissible limits of FAO (0.2 mg/L) for agriculture use [18].According Elenhorn and Barceloux [27] mostly water contamination of copper occurs due to untreated industrial wastewater pollution.…”

“…The cadmium concentration in all sampling areas was found to be within limits (0.1 mg/L) set by NEQS. High concentration of Cd was observed at sampling area S-1, S-2.Concentration of cadmium was found to be diluted where KPOD enters near disappeared Cholri weir area (Fig.1).The cadmium concentration in all sampling areas was also found to be within permissible limits of FAO (0.1 mg/L)for agriculture use [18].According a study conducted for industrial effluent near Karachi, reported concentration of Cd was 0.004-2.4 mg/L, by Saif et al [17]. Similar results were also reported by Tariq et al [19] andAli et al [24] for assessment of industrial and sewage effluents.According Iqbal and Edyvean,Khuhawar and Majidano , Devnani and Satsangee , andIqbal et al [20,21,22 and 23] the major sources of Cd contamination are batteries, fertilizers,electroplating, smelting, paint pigments, mining and alloy industries.Though only sugar mill industries can be traced in district Badin (Fig 1),to find out other industries contributing cadmium pollutantsis very dificult task for present study, as LBOD caries industrial effluent of three distrits which are hundreds of km away from present study of areas.…”

Monitoring of some disinfection by-products in drinking water treatment plants of El-Beheira Governorate, Egypt

“…For Plant 2, it was detected only in autumn. These ranges are higher than the ranges reported by Othman et al (2012) in Ismailia Canal in Egypt (0.07-1.49mg/L). It was not present in all treated water samples (Fig.…”
