Mh. Martin et al., CONCENTRATIONS OF CADMIUM, COPPER, LEAD, NICKEL AND ZINC IN THE ALGA FUCUS-SERRATUS IN THE SEVERN ESTUARY FROM 1971 TO 1995, Chemosphere, 34(2), 1997, pp. 325-334
Changes in the Cd, Cu, Ni, Pb and Zn concentrations in the mature thal
lus of the seaweed Fucus serratus collected from a lower-shore site in
the heavily polluted Severn Estuary, (U.K), were recorded from 1971 t
o 1995. Over the period of observation Cd showed a dramatic reduction
in concentrations whilst Pb showed low concentrations throughout the m
onitoring period due, it is suggested, to low of solubility/bioavailab
ility of Pb in this environment with its high pH and high suspended-se
diment load. Seasonal changes of Cd, Cu and Zn concentrations were obs
erved in this alga. Concentrations of metals in the mature thallus, ex
pressed as two-monthly means, showed highest values in March/April and
lowest values in September/October. (C) 1997 Elsevier Science Ltd.
