Nature of Distribution of Mercury in the Sediments of the River Yamina (Tributary of the Ganges), India

Short-length sediment cores, surface sediments, and suspended particulate matter (SPM) from the River Yamuna, the kargest tributary to the River Ganges, India, were analyzed for total mercury. SPM displayed higher levels of total Hg relative to surface sediments. Finer fractions preferentially showe...

Summary:Short-length sediment cores, surface sediments, and suspended particulate matter (SPM) from the River Yamuna, the kargest tributary to the River Ganges, India, were analyzed for total mercury. SPM displayed higher levels of total Hg relative to surface sediments. Finer fractions preferentially showed higher Hg levels while total Hg was equitably distributed among all size fractions in the lower reaches of the river. Vertical distribution of Hg in sediment cores shows systematic peaks, indicating that Hg addition to the riverine system is in direct proportion to the increase in anthropogenic activities in the midstream region.
