Jan 1, 2023 · Biological (marine bacteria, phytoplankton, algae, and other marine organisms) factors perform a significant contribution to arsenic speciation and the biogeochemical cycle of arsenic in the marine environment.

May 6, 2019 · Amongst the huge variety of life on Earth, there are some mighty resilient microorganisms out there. Now, scientists have tracked down an ocean microbe that survives by breathing arsenic – the chemical element we humans regard as a notorious poison.

Arsenic in the environment pose major threats to human health, and especially the inorganic form can result in adverse health effects. This review analyse papers from 2004 to 2017 on As in fresh fish and molluscs caught in the Mediterranean sea …

Dec 20, 2021 · Due to environmental toxicity and the existence of multiple chemical species of arsenic (As), the distribution and behaviour of this element have received more attention in estuarine, coastal and shelf areas. In the coastal waters, riverine discharge mainly dominates the concentrations of As.

Mar 1, 2019 · The USGS investigates the presence and effect of arsenic in drinking water supplies, monitors the worldwide distribution of arsenic in groundwater, and assesses the impact of arsenic on local stream sediment chemistry.

Groundwater arsenic contamination is widespread in Texas. Approximately 6% of wells exceed the MCL of 10 ug/L. Contamination is focused in the southern High Plains (32% of wells exceed than the MCL) and the southwestern Gulf Coast (29% of …

The amounts of arsenic found in some animal tissues as a result of normal exposure are presented in Appendix B. Arsenic in abnormal amounts may be ingested by eating plants or drinking water contaminated with arsenic, breathing arsenic-containing dusts, or ingesting arsenic as a medicine or poison.

Feb 1, 2023 · Arsenic is a ubiquitous contaminant in coastal aquifers, which is extremely sensitive to ambient geochemistry conditions. This study showed that both seawater intrusion and MAR could intensively alter the native geochemistry of aquifer, resulting in the mobilization and repartition of As.

Bivalves, such as oysters and mussels, are exposed to environmental pollutants, like microplastics (MPs) and arsenic (As). This study investigated co-existence and interaction of MPs and As (total As and As species) in two bivalve species from the Chinese coastline.

The effects of nutrient distribution and structure on the behavior and speciation of dissolved inorganic arsenic (DIAs) in coastal waters were analyzed based on the data of 48 surface water samples collected in the southwestern coast of Laizhou Bay and its adjacent rivers (SWLZB).
