The use of L-ascorbic acid in speciation of arsenic compounds in drinking water [PDF]

open access: yesActa Periodica Technologica, 2009
Arsenic speciation, besides total arsenic content determination, is very important in analysis of water, foodstuffs, and environmental samples, because of varying degrees of toxicity of different species.

Absorption and speciation of arsenic by microalgae under arsenic-copper Co-exposure

open access: yesEcotoxicology and Environmental Safety, 2021
Combined pollutions of arsenic (As) and copper (Cu) are common in water bodies near mines, non-ferrous metal smelting and power plants. This study investigated the effect of Cu(II) on the absorption and speciation of As(V) by microalgae.
