Heavy metal determinations on sediments - particle size dependence II. - Liverpool Bay river inputs

Previous work has shown that the distribution of heavy metals on river and estuarine sediments is not confined to the fine fraction where surface adsorption from solution takes place. Metals present in the coarser sediments can sometimes greatly exceed in quantity those present on the clay minerals. Because of the continuing work on the disposal of sludge and dredging spoil in Liverpool Bay, the metal concentrations in the sediments of rivers flowing into the bay were determined in order to compare these metal sources which are in addition to those of sludge and spoil.
