“…Nowadays, health care infections and the associated high mortality rate is very high in many hospitals [1]. Nosocomial infections are one of the most important infections, that occur in patients hospitalized due to non-infectious diseases and are considered as one of the main causes of mortality in hospitals, which subsequently increase the cost of health cares for the health system [[2], [3], [4], [5], [6]]. Recently, nosocomial infections are considered as the most important causes of mortality and morbidity among patients admitted in to Intensive Care Unit (ICU) while the majority of patients admitted in to these wards are immunocompromised.…”

Food contamination by heavy metals can lead to the accumulation of these elements in the body of consumers and the contraction of diseases. Accordingly, heavy metal concentration in common carp fishes consumed in Shiraz, Iran was determined in the present study. The mean concentrations of Pb, Cd, Zn, and Cu were 0.23, 0.07, 0.47, and 0.59 mg/kg (dry weight), respectively. The average concentration of heavy metals in the muscle of common carps consumed in Shiraz was less than the permissible standard of the WHO and FAO. The estimated weekly intake (EWI) of the studied metals was below the provisional tolerable weekly intake (PTWI). The maximum and minimum relative risk (RR) equaled 48.93 and 0.55% of the total risk for Cd and Zn, respectively.

“…Over the past years, various studies have used nitrate for groundwater contamination assessment. Qasemi et al (2018a) identified in arid and semi-arid areas in villages of Azadshahr, northeastern Iran about 7% of the villages exceeds the EPA standard concentration for nitrate. In Prince Edward Island, Canada, 6% of domestic wells showed nitrate concentration higher than the WHO guideline (Savard, 2016); in Jinghui canal irrigation area of the loess region, northwest China, 50% of the groundwater samples crossed the drinking water standard for nitrate (Zhang et al, 2018).…”

“…Based on the International Agency for Research on Cancer regulations (IARC, 2010), nitrate and nitrite are treated as "probably carcinogenic to humans". As a result, drinking water contaminated by the nitrate is a severe environmental health hazard that requires special attention by the decision-makers to reduce contamination (Qasemi et al, 2018a).…”

Sources and health risk assessments of nitrate in groundwater, West of Tahta area, Sohag, Egypt

Due to natural and anthropogenic human activities in arid and semi-arid regions, groundwater will continuously suffer from severe contaminations such as increases in nitrate levels. Groundwater contamination poses serious threats to the environment and human health. In the current study, 23 groundwater samples were collected from the desert zone around the wastewater treatment plant west of Tahta area, Sohag, Egypt. The samples were chemically and bacteriologically analyzed to quantify the sources and potential risk of nitrate in groundwater to the health of adults, children and infants. The nitrate showed wide spatial variability in the studied area, with values going from 0.38 up to 59 mg/L. Based on the bacteriological, principal component, NO 3 and NO 3-/Clanalyses, nitrate in the southwestern parts around the wastewater treatment plant developed from the sewage contamination while the northeastern and southern parts are mainly due to contamination from the agricultural activities and organic wastes. The non-carcinogenic hazard quotients (HQ) values of 78% of infants, 70% children and 4% of adults were higher than the safety level (i.e., HQs>1), suggesting severe health effects on human health. Proper management of wastewater disposal activities and application of fertilizers are required to reduce groundwater contamination in Egypt and globally.
