Arsenic is a toxic metalloid that is widely distributed in the environment due to its persistence
and accumulative properties. The occurrence, distribution, and biological effects of arsenic …

The fate of arsenic—a redox sensitive metalloid—in surface sediments is closely linked to
early diagenetic processes. The review presents the main redox mechanisms and final …

The concentrations of heavy metals (As, Cd, Cr, Cu, Hg, Ni, Pb and Zn) and major metals (Al,
Fe and Ti) in 42 surface sediment (0–2 cm) samples from Erhai Lake, a large eutrophic …

Arsenic (As) contamination is a major global environmental concern with widespread effects
on health of living organisms including humans. In this review, the occurrence (sources and …

Arsenic (As) is extremely toxic to living organisms at high concentration. In aquatic systems,
As exists in different chemical forms. The two major inorganic As (iAs) species are As V …

The seasonal variation in lake water arsenic (As) and antimony (Sb) concentrations was
assessed in four small (< 1.5 km 2) subarctic lakes impacted by As and Sb emissions from …

Arsenobetaine is one of the major organoarsenic compounds found in aquatic organisms,
including seafood and fish meant for human consumption. It has been widely studied over …

An efficient adsorbents for arsenate removal was developed by modification of calcined
eggshell with goethite (calcined eggshell/goethite; sorbent 1), α-MnO 2 (calcined eggshell/α …

Arsenic (As) is quite an abundant metalloid, with ancient origin and ubiquitous distribution,
which represents a severe environmental risk and a global problem for public health …

This review is focused on the biogeochemistry of arsenic in freshwaters and, especially, on
the key role that benthic microalgae and prokaryotic communities from biofilms play together …
