TLDR
The most sensitive and selective methods combine reduction, separation, and emission type detectors are applied and the intensity of arsenic atomic emission lines is observed.Abstract:
Because of its biological activity, arsenic is involved in an active global geochemical cycle. Arsenic has been found to be transferred to the atmosphere, at least in part, by evolution of trimethy...read more

Accumulation of heavy metals by vegetables grown in mine wastes.
TL;DR: In this paper, the metal concen- trations were found to be heterogeneous in mine wastes and in soils mixed with mine wastes, and four plant species, namely iceberg lettuce, Cherry Belle radishes, Roma bush beans, and Better Boy tomatoes, were investigated.

Graphite furnace atomic absorption spectrophotometers as automated element-specific detectors for high-pressure liquid chromatography
Frederick E. Brinckman,K L Jewett,Warren P. Iverson,Kurt J. Irgolic,K.C. Ehrhardt,R.A. Stockton +5 more
TL;DR: In this article, two automated high-pressure liquid chromatography (HPLC) systems with element-specific detectors, capable of detecting, identifying and quantitating trace element compounds were developed independently in our laboratories.
Journal ArticleDOI
Epidemiology and toxicology of arsenic poisoning in domestic animals.
TL;DR: Arsenic poisoning is one of the more important causes of heavy metal poisoning in domestic animals and two species--dogs and cattle--are intoxicated more frequently than other animals; yet sporadic instances of poisoning have been observed in cats, horses, and pigs.
Journal ArticleDOI
Analytical approaches for arsenic determination in air: A critical review.
TL;DR: This review describes the different steps involved in the determination of arsenic in air, considering the particulate matter and the gaseous phase, and focuses on sampling, sample preparation and instrumental analytical techniques for both total arsenic determination and speciation analysis.

Metal Cycles and Biological Methylation
P. J. Craig,P. J. Craig +1 more
TL;DR: The equilibrium between the various forms, species and locations of each heavy metal is a dynamic not a static one, and the importance of heavy metals in the biosphere has to be considered in the context of a cycle between these forms and locations as mentioned in this paper.

Methylated Forms of Arsenic in the Environment
TL;DR: Environmental samples were analyzed for arsenate and arsenite ions and the methylarsenic acids in nanogram amounts and Dimethylarsinic acid and methylarsonic acid were found in natural waters, bird eggshells, seashells, and human urine.
Journal ArticleDOI
Gas-sampling technique for arsenic determination by atomic absorption spectrophotometry
TL;DR: The above “flameless” technique cannot be used to determine arsenic because of the high temperature required to maintain arsenic in its vapor state.
