Water, is generally known to sustain life. This implicitly means that every living thing needs water to survive, as it plays a very important role in the maintenance of metabolic processes.
Water is known to be a universal solvent and as such contains so many dissolved elements. Among these elements are heavy metals, the presence of which have deleterious effect on living things including humans.
Metals have been recognized as toxins for centuries. For instance, arsenic poisoning was a favored way to dethrone royalty in the Renaissance era. In the 1950’s a tragic case of mercury poisoning was reported in the Minamata Bay of Japan where large quantities of industrial mercury was dumped into the bay. In 1971, mercury contamination of seed grains claimed the lives of some 6000 people in Iraq. In Northern part of Nigeria, a case of lead poisoning was recently reported.
AIMS AND OBJECTIVE:
Because of the poisonous effects of these heavy metals namely, lead, Arsenic, mercury, Aluminum, cadmium, cobalt, chromium, nickel etc as well as organophosphates, nitrates’ and nitrites’ it is pertinent to assess the levels of some of these analytes in various water sources in Enugu, a geographical zone laden with coal.
It is against this background that the investigators have embarked on this study to ascertain the safety or otherwise of water consumed in Enugu.
MATERIALS AND METHOD
Water for analysis will be collected from pond wells, surface water, borehole, streams as well as sachet water (“pure water”) and the quantitation of the toxic metals will be by Atomic Absorption Spectometry (AAS).
