A comparative analysis of lead (Pb) and cadmium heavy metals contents in bottled and refilled drinking water in Sukarame District, Bandar Lampung.

The primary need of humans is access to safe drinking water. These requirements expand the availability of water supply facilities, refilled drinking water, and bottled drinking water. Heavy metals are transition elements with large atomic masses. This study aims to assess the heavy metals lead (Pb) and cadmium (Cd) in bottled and refilled drinking water using Ministry of Health Regulation No. 492/Menkes/Per/IV/2010. An atomic absorption spectrophotometer was used to test samples of five local bottled drinking water brands and twelve refilled drinking water Sukarame sub-district. The tests found that certain heavy metals exceeded the government's maximum level. The AMDK5, with a Pb content of-0.007 mg/L and a Cd concentration of 0.001 mg/L, was one of five bottled water samples with acceptable quality. The Pb and Cd content in the other four samples, on the other hand, surpassed the maximum standard. Pb and Cd levels in refilled drinking water were measured, and the results were mixed. Pb values in five of the twelve refilled drinking water samples exceeded the maximum standard of 0.01 mg/L. Furthermore, the Cd content in twelve samples of refilled drinking water exceeded 0.003 mg/L, which violated the requirement. [ABSTRACT FROM AUTHOR]
