Hazardous-waste-management factories are an important economic
activity in rapidly developing countries like Thailand,
where, for example, 616.5 tons of hazardous waste have been
the source of environmental problems [2]. Although hazardous
waste is a major source of mercury exposure, the release of this
metal from consumer products and devices - electrical switches,
fluorescent lights, and batteries - can also contribute to public
exposure [3,4]. This type of pollution is transmitted via these
media, and will impact, directly or indirectly, upon humans
and the natural environment: the biota, air, soil, and water [5].
