Abstract

Inputs of industrial and domestic effluents create a region of anoxic conditions in the water column of the upper estuary. Arsenic concentrations and speciation in the watershed shows that the ratio of As (III) to As (V) is elevated in the anoxic part of the estuary and those tributaries that are depleted in oxygen. The combination of a near-constant anthropogenic arsenic emission and seasonally fluctuating water discharge creates a variable arsenic concentration in the river end member. This variability can explain the non-linearity in the arsenic-salinity relationship in the estuary, where a pronounced arsenic maximum is seen in a region without local arsenic sources
