“…In this study, the mean concentration of iron in drinking tap water were significantly higher when compared with bottled water samples This came in accordance with the previous studies done by Taylor et al (2005) and Niu et al (2006) and in agree with that explained by Lasheen et al (2008), who reported that iron and lead release from different types of water pipes used in Egypt namely polyvinyl chloride (PVC), polypropylene (PP) and galvanised iron (GI) depend on stagnation time, pipe age, pipes material and water quality parameters such as pH, alkalinity and chloride to sulphate mass ratio and in general, GI pipes showed to be the most effected by water quality parameters tested and the highest iron release and PVC pipes are the most lead releasing pipes while PP pipes are the least releasing.…”

PurposeThis study seeks to find out if chronic exposure via drinking water to high doses of a mixture of metals found as contaminants in tap and bottled water sources can alter the systemic physiology of residents.Design/methodology/approachA case control study was designed, 18 subjects drinking mainly tap water as main group (group I) and 15 subjects drinking exclusively bottled water as control group (group II) for a minimum of two years. Cadmium, lead, chromium and iron concentrations in drinking tap and bottled water samples were measured. The effect potential of the same metals were evaluated by assessing liver and kidney functions and haemoglobin levels for the studied subjects.FindingsIron concentration was found to be significantly higher in drinking tap water samples compared to bottled. Chromium, lead and iron were significantly higher in blood samples of group I subjects compared to the control group. Blood creatinine levels were positively correlated with that of chromium and cadmium of group I; and chromium levels of group II. Urea levels was positively correlated with lead levels of group I. Haemoglobin was positively correlated with iron blood levels of group I and negatively with lead levels of group II. No appreciable changes were found in the blood clinical markers of the liver functions of either group.Originality/valueThis study gives a concise idea about the higher level of some heavy metals in tap water compared to bottled and how heavy metal contaminants in drinking water may affect kidney function and haemoglobin level of consumers.

“…Living conditions: Pb water pipes and paint are still found in older houses, often in deprived communities [27,28], although it is paint, rather than water pipes, which is the more common source of exposure in children in high-income countries nowadays [29][30][31][32][33]. Nevertheless, residual contamination in the wider urban environment might still be an issue [34,35], particularly to the poorer member of a society, including migrant groups, who are over represented in the less developed and more deprived parts of the urban landscape [36,37].…”

High quality and accurate environmental investigations and analysis are essential to any assessment of contamination and to the decision-making process thereafter. Remediation decisions may be focused by health outcomes, whether already present or a predicted risk. The variability inherent in environmental media and analysis can be quantified statistically; uncertainty in models can be reduced by additional research; deep uncertainty exists when environmental or biomedical processes are not understood, or agreed upon, or remain uncharacterized. Deep uncertainty is common where health and environment interact. Determinants of health operate from the individual's genes to the international level; often several levels act synergistically. We show this in detail for lead (Pb). Pathways, exposure, dose and response also vary, modifying certainty. Multi-disciplinary approaches, built on high-quality environmental investigations, enable the management of complex and uncertain situations. High quality, accurate environmental investigations into pollution issues remain the cornerstone of understanding attributable health outcomes and developing appropriate responses and remediation. However, they are not sufficient on their own, needing careful integration with the wider contexts and stakeholder agendas, without which any response to the environmental assessment may very well founder. Such approaches may benefit more people than any other strategy.

“…Також доведено, що концентрації свинцю та заліза збільшується зі збільшенням співвідношення концентрацій хлоридів і сульфатів у воді для всіх типів труб. Найбільше заліза вилуговувалося із труби з оцинкованого заліза, свинцю -із ПВХ труби порівняно з поліпропіленовою [13].…”
