Analysing the Heavy Metal Profile in Bottled Water and Sachet Water Samples from Various Markets in Lagos, Nigeria

Water is an essential component of the body’s metabolic activities. The World Health Organization has established criteria for drinking water. Water is a life-sustaining beverage that is required for all species to survive. A major public health priority is the provision of safe drinking water. The intake of polluted water causes the majority of ailments in impoverished countries. Using Atomic Absorption Spectrophotometry, the amounts of six heavy metals and six trace metals in sachet water samples and bottled water samples collected in Lagos markets, Nigeria, were measured (AAS). Except in the Bevap sachet water, Osan bottled water, Christo bottled water, and Cway bottled water samples, lead contents were below the maximum permitted values. Except for Pringad bottled water, Sunar bottled water, and Cway bottle water samples, as well as Nimbus satchet water, cadmium was not discovered in majority of the water samples. These levels were higher than the WHO’s maximum allowed limits. Chromium was detected in trace quantities in all of the water samples tested. All of the other heavy metals tested were below the maximum allowable values. Iron, manganese, calcium, magnesium, sodium, and potassium were also found at non-toxic quantities in the water samples. Heavy metals were found in five sachet water tests and seven bottle water samples, as well as concentrations of lead and cadmium in three satchet water samples and three bottled water samples. This could be hazardous if the population consumes it over an extended period of time.
