摘要: Abstract The long-term uptake and release of zinc, cadmium, lead mercury by the seaweed Ascophyllum nodosum were studied in situ transferring whole plants from localities with low, to high, levels heavy metals water vice versa. Zinc cadmium taken up very slowly winter relatively quickly summer while showed comparatively little seasonal variation. results for less clear, but indicated a moderate marked It is suggested that zinc require an input metabolic energy accumulation may be governed ionic-exchange process similar known strontium. practical use A. as bioindicator metal pollution discussed.
