Water quality and risk assessment of copper content in drinking water stored in copper container

Abstract

In most developing countries, drinking water is still a serious challenge. Many water purification methods exist, but they are costly and out of reach for many people. Copper is an ancient metal that has been used from several thousands of years. Because of its antibacterial properties, ancient cultures held this metal in high regard. Copper vessels are still in use today for storing drinking water due to its ability to purify water. Therefore, the objective of this study was to evaluate the copper concentration in drinking water after storing in copper containers/bottle over different time periods with respect to copper safety levels. For this study, water is stored in a copper container up to 168 h and the water samples are collected at different intervals. The concentration of copper is analyzed in water samples using ICPMS, and it ranges from 0.009 to 0.823 mg/L, which indicates as time increases simultaneously copper content also raises in the stored water. The higher copper content was detected at sample@168 h which was also well within the permissible limits of World Health Organization and United States Environmental Protection Agency.

Investigation of several heavy metals in Al-Saddah agricultural drainage in Hilla city /Iraq

“…Irrigation water that contains heavy metals can raise alert from a health point of view since those heavy metals cannot degrade and they can accumulate in soil and plant and, and become in direct contact with humans and cause a variety of health problems [23]. Copper (Cu), it's a vital element that is required in a small amount for the human well fair as it is needed for immunity and bones, cholesterol metabolism [24]. Cu can enter the environment from different sources such as mines, industrial waste, landfills, fertilizers, as well as domestic waste [25] The results are shown in Fig.…”

Electroanalytical Determination of Copper(II) Ions Using a Polymer Membrane Sensor

“…Trace metals are toxic for many organisms above a threshold concentration (for instance, the maximum containment level of copper is 1.3 mg/L according to EPA and WHO), and thus the presence of these metal ions in the environment and the food must be precisely and periodically monitored, making its determination in various media an essential analytical task [1][2][3][4]. Copper is one of the essential trace elements, and it has a high importance in industry, environmental and biological systems since it plays central roles in many biochemical processes.…”

Copper (II)-Catalyzed Oxidation of Ascorbic Acid: Ionic Strength Effect and Analytical Use in Aqueous Solution

“…Copper is a dangerous pollutant of water bodies [4,5] and drinking water, which could be contaminated from copper containers [6]. This shows the importance of copper (II) control in aqueous medium.…”
