説明
Leachates from solid waste disposal sites and road deposits were focused on as sources of heavy metals in water environment. A comparative study of the concentrations of heavy metals was carried out for samples collected in the Philippines and in Japan. Heavy metals were not removed in the oxidation ponds designed for leachate treatment in the Philippines. The chemical compositions of the leachates from a site in the Philippines and that from a site with a low content of incineration residuals in Japan were similar in terms of general water quality parameters. Relatively high concentrations of lead and antimony and very high concentrations of tin were observed in the leachate from the site in the Philippines. The comparison of the concentrations of heavy metals in road deposits showed that the concentrations of heavy metals in unit dry weight of road deposits were in the same range regardless of the countries where the samples were collected. It was suggested that lead might be a suitable indicator of the pollution of sediments in water environment caused by urban deposits. A model calculation showed that the contribution of disposal site leachates to that of the overall heavy metal loads discharged to the water environment in Tokyo was 1/200 of the contribution of road deposits, while the same calculation showed 1/10 for the Philippine case.
