[Mixing behavior of arsenic in the Daliaohe Estuary].

Mixing behavior of arsenic in the Daliaohe Estuary was studied. Twenty samples were collected from the Daliaohe Estuary during April, July and November, 2010 and arsenic was determined by HG-AFS. The concentrations of arsenic varied from 2.

[Effect of the first water-sediment regulation on the variations of dissolved inorganic nutrients' concentrations and fluxes in the lower main channel of the Yellow River].

The variations and fluxes of dissolved inorganic nutrients were studied, based on continuously monitored data in the lower main channel of Yellow River (Lijin) during the period of water-sediment regulation in July 2002. Concentrations rang from 169.3 to 273.

[Distributions of arsenic and selenium in the Yangtze estuary and its adjacent areas].

One cruise of "Haijian 47" was carried out in September 2004, to understand the behaviors of selenium and arsenic in the Yangtze Estuary and its adjacent areas. Selenium and arsenic species are determined by HG-AAS. Concentrations rang from 13.

Hydrochemical processes controlling arsenic and selenium in the Changjiang River (Yangtze River) system.

The hydrochemistry of arsenic and selenium in the Changjiang (Yangtze River) was studied, based on continuously monitored data at Nantong station (i.e. 180 km inland from river mouth), the main Changjiang channel and 10 major tributaries.
