Antimony pollution in China.
TL;DR: The local environments around Sb mining and smelting areas were seriously contaminated and plants growing in these contaminated soils accumulated high levels of Sb and exceeded the tolerable concentration, thus threatening the health of local inhabitants.

TL;DR: The mineral and trace element content of medicinal herbs and their infusions showed a wide variability, however, distribution of the elements in the infusions is not high and it is nil especially for Cd, Co, Cr and Pb.
Journal ArticleDOI
Arsenic, cadmium and lead in medicinal herbs and their fractionation.
TL;DR: It was established that the major part of arsenic and lead in herbal infusions existed in biomacromolecular fraction.

Simultaneous speciation of inorganic arsenic and antimony in water samples by hydride generation-double channel atomic fluorescence spectrometry with on-line solid-phase extraction using single-walled carbon nanotubes micro-column
Hong Wu,Xuecui Wang,Bing Liu,Yueling Liu,Shanshan Li,Jusheng Lu,Jiuying Tian,Wenfeng Zhao,Zonghui Yang +8 more
TL;DR: In this paper, a new method was developed for the simultaneous speciation of inorganic arsenic and antimony in water by on-line solid-phase extraction coupled with hydride generation-double channel atomic fluorescence spectrometry (HG-DC-AFS).
Journal ArticleDOI
Comparative study of atomic fluorescence spectroscopy and inductively coupled plasma mass spectrometry for mercury and arsenic multispeciation
TL;DR: Multispeciation based on ICP-MS exhibits better sensitivity than the coupling based on tandem atomic fluorescence, but this second device is a very robust system and exhibits obvious advantages related to the low cost of acquisition and maintenance, as well as easy handling, which makes it a suitable system for routine laboratories.

Comparison of biota sample pretreatments for arsenic speciation with coupled HPLC-HG-ICP-MS
TL;DR: Soxhlet extraction has been compared to sonication and microwave assisted extraction of arsenite, arsenate, dimethylarsenic, and arsenobetaine from biota samples (oyster, cockle,======mussel and fresh water alga) and certified reference materials TORT-1 and======CRM 627, using methanol and methenol-water mixtures as discussed by the authors.

Antimony speciation at ultra trace levels using hydride generation atomic fluorescence spectrometry and 8-hydroxyquinoline as an efficient masking agent
TL;DR: In this paper, 8-hydroxyquinoline was used to mask undesired fluorescence emission from Sb(V) during the determination of Sb (III) and make Sb speciation more accurate.
