KANDUNGAN Pb, Cd, Hg DALAM AIR MINUM DARI DEPOT AIR MINUM ISI ULANG DI JAKARTA, TANGERANG, DAN BEKASI

<p>A study on chemical quality of drinking water from reffil depots was done in Jakarta, Tangerang, and Bekasi in 2003 to determine the contents of heavy metals such as lead (Pb), cadmium, (Cd), and Mercury (Hg). A total of 38 refill depots was selected as samples. Data were collected by water sampling collection and water analysis, and interview with operators and association personal using questionairs. Water samples were analyzed using Atomic Absorption Spectrophotometer (AAS) to examine the contents of their heavy metals based on raw water and drinking water standards. The results showed that the treatment processed were filtration and disinfection. However, the contents of heavy metals in the two types of water samples still complied with the standards stated in Health Ministerial Decree no 906 in the year 2002.</p> <p> </p> <p>Keywords: heavy metals, drinking water, drinking water refill depots
