| Abstract | ||
| Six house-hold Abyssinian pumps distributed in different villages of Mansoura (Mans-I, Mans-II and Mans-III) and Talkha (Talk-I, Talk-II and Talk-III) cities, Egypt, were selected for regular seasonal water quality assessment during 2017. Water samples were collected within the mid-periods of four seasons namely, winter, spring, summer and autumn. The selected metals include Sodium (Na, an alkali metal), Barium (Ba, an alkaline earth metal), lead (Pb), Aluminium (Al) (two post transition metals), Manganese (Mn), Cadmium (Cd), Chromium (Cr), copper (Cu), iron (Fe), zinc (Zn), molybdenum (Mo) (seven transitional metals), antimony (Sb), arsenic (As) (two metalloids) and Se (non-metalloid) Metal analysis was carried out by Inductively Coupled Plasma-Mass Spectrometry (ICPMS). The selected elements maintained both health hazardous and aesthetic water quality effects, and all have been assigned drinking water guidelines by World Health Organization (WHO) [1]. The results indicated that, concentration levels of all elements displayed remarkable local and seasonal variations. Based on the WHO drinking water guidelines of heavy metals, all water samples collected only from Mans-I pump were health safe with acceptable guidelines of drinking water. However, water samples collected from the other five pumps showed remarkably high levels mostly exceeding the guidelines of acceptable drinking water quality. Concisely, all water samples collected from Mans-I pump were health safe with acceptable drinking water guidelines while samples collected from other pumps can impose great human health risks if used for drinking. | ||
