Environmentalists in the Philippine capital and several other international non-governmental organizations have urged the proper disposal of toxic waste after they detected high levels of mercury smoke in the harbor area of Tondo district.
An investigation conducted on 19 April at the Pier 18 Garbage Transfer Station showed 117.2 micrograms per cubic meter (µg/m3) in 14 used mercury-containing compact fluorescent lamps in two separate disposal areas in Manila's district, which is one of the most densely populated areas in the world. One lamp registered mercury vapor at 502.4 µg/m3, the PDI reported.
