Distribution of heavy metals in Tamshui mangrove forest ecosystem

Journal Article:

Abstract

Tamsui estuary area is one of the few places in Taiwan where mangrove is still growing. Heavy metals, carried by the water of the Tamsui river, are accumulated in the estuary soil. Most heavy metals in soil, however, are immobile under reducing conditions and are fixed in the large amount of organic matter present. Heavy metals are distributed at different concentrations in various tissues of Kandelia candel as well as grasses of Phragmites communis, Imperata cylindrica, and Cyperus malaccensis growing in the swamp area. The concentration of heavy metals was significantly higher root than in stems and leaves. The absorption of heavy metals by the plants was less in soil that was frequently submerged. Kandelia candel seems to have no special tolerance to copper and zinc. The soil environment which favors reduced availability of heavy metals may help Kandelia candel adapt to growth in the polluted estuary.
