Water quality is a topic of concern in many areas around China, especially in the south-eastern parts where population is extremely dense. High concentrations of specific metals can be harmful to the general public, so it is important to observe whether these metal concentrations are within safe limits. Here, heavy metal concentrations in both direct-drinking water and running water were tested by ICP-MS in both Bao’an and Nanshan districts in Shenzhen. The manganese, copper, arsenic, selenium and cadmium concentrations were below the recommended regulatory values, but iron, zinc and lead concentrations were higher than the recommended regulatory values in certain samples in both districts. This is a potential health hazard that should be investigated further.
