Marine and terrestrial contributions to atmospheric deposition fluxes of methylated arsenic species

Nature Communications
Arsenic, a toxic element from both anthropogenic and natural sources, reaches surface environments through atmospheric cycling and dry and wet deposition. Biomethylation volatilizes arsenic into the atmosphere and deposition cycles it back to the surface,

Arsenic phase distribution in Zimapán mine tailings, Mexico [PDF]

Geofísica Internacional, 2003
Arsenic contamination of groundwater has been linked to natural and anthropogenic sources in Zimapán, Mexico. Leaching of mine tailings was identified as one of the man-made causes of environmental arsenic pollution.

Tissue-specific trace element accumulation, mercury and arsenic speciation in Atlantic walrus (

Ecotoxicology and Environmental Safety
Walruses ( Odobenus rosmarus ) are long-lived Arctic marine mammals and play an important ecological and cultural role in northern communities. We quantified and compared concentrations of 34 elements in blubber, liver, and muscle tissues from 97 ...

Steady-state groundwater arsenic concentrations in reducing aquifers

, 2018
Arsenic is a common soil and groundwater contaminant in much of the world. Groundwater arsenic is commonly derived from the reductive dissolution of arsenic-bearing iron oxides.

Arsenic speciation in seafood from the North Adriatic sea

, 2008
Since the toxicity of arsenic varies with the chemical form, speciation is mandatory to assess the safety of seafood. An IC-ICP/MS method for the determination of arsenobetaine, arsenocholine, dimethylarsiniac acid, arsenic lll and arsenic V in seafood
