Abstract
Concentrations of mercury, lead, copper, zinc, cadmium, iron and partially chromium, manganese, nickel and aluminium, were recorded in surface sediments at the lower reaches of 11 rivers from the Mediterranean coastal zone of Israel, during 1988-1993. Excluding the lower Kishon river, no major contamination was found at most of the stations when trace metal concentrations were normalized against iron concentrations (trace metal/ iron ratios) and compared to levels recorded in stream sediments from the southern drainage basin of the Kishon river. Minor enrichments found in part of the rivers are attributed to land-based point sources of pollution. Variations in trace metal concentrations at the estuaries are related to high influx of fine-grained sediments transported by heavy floods during rainy winters, which later are resuspended and transported seaward by bottom currents.
