FORESTS 17/03/21 The Effects of Forest Litter and Waterlogging on the Ecotoxicity of Soils Strongly Enriched in Arsenic in a Historical Mining Site. This study examined the effects of waterlogging and forest litter introduced to soil on chemical properties of soil pore water and ecotoxicity of soils highly enriched in As.
These effects were examined in a 21-day incubation experiment. Tested soil samples were collected from Złoty Stok, a historical centre of arsenic and gold mining: from a forested part of the Orchid Dump (19,600 mg/kg As) and from a less contaminated site situated in a neighboring forest (2020 mg/kg As). An unpolluted soil was used as control. The concentrations of As, Fe and Mn in soil pore water were measured together with a redox potential Eh. A battery of ecotoxicological tests, including a bioassay with luminescence bacteria Vibrio fischeri (Microtox) and several tests on crustaceans (Rapidtox, Thamnotox and Ostracodtox tests), was used to assess soil ecotoxicity. MethodsX Volume 8, 2021, Determination of four arsenic species in environmental water samples by liquid chromatography- inductively coupled plasma - tandem mass spectrometry.
Motivation and background methods Arsenic species have been measured using a variety of techniques that have been reviewed extensively , , ,  with many recent methods focusing on chromatographic separation of As species and detection/quantitation of As by inductively coupled plasma-mass spectrometry (ICP-MS) [1,3,5].
When measuring As(III), As(V), DMA, and MMA, anion exchange separation is sufficient for retention and separation because all four species are anionic. Methods that use anion exchange columns, including the Hamilton PRP-X100 column, are widespread , , , and when paired with a nitrate/phosphate mobile phase are promising for achieving good separation of As(III) and DMA, which can be particularly challenging.

Health 2019, 16, 3436. Communicating Arsenic’s Risks. Arsenic is a naturally occurring toxic metalloid that has many human health implications.
Its strong prevalence in the bedrock and thus much of the well water in New England puts many private well owners at risk. It is also found in food products, particularly those that contain rice. Despite the documented health risks, arsenic is not high on the list of concerns for residents of the region.

STANFORD_EDU 05/06/18 Stanford researchers find groundwater pumping can increase arsenic levels in irrigation and drinking water. For decades, intensive groundwater pumping has caused ground beneath California’s San Joaquin Valley to sink, damaging infrastructure.
Now research published in the journal Nature Communications suggests that as pumping makes the ground sink, it also unleashes an invisible threat to human health and food production: It allows arsenic to move into groundwater aquifers that supply drinking water for 1 million people and irrigation for crops in some of the nation’s richest farmland.
Groundwater is the main source of drinking water for 1 million people in California’s San Joaquin Valley, part of the arid Central Valley that supports a $17 billion agricultural industry.

International Journal of Sustainable Built Environment Volume 6, Issue 2, December 2017, An analysis of the cost-effectiveness of arsenic mitigation technologies: Implications for public policy. Natural groundwater arsenic contamination is reported in more than 100 countries worldwide, affecting an estimated 202.3 million people’s lives (IWA., 2016, Singh, 2017, Singh and Stern, 2017).
Arsenic is a naturally occurring metalloid and a group A human carcinogen, widely distributed in Earth's crust (USEPA, 1999, Ravenscroft et al., 2009). Among the arsenic-contaminated countries, half have only recently identified the problem (Ravenscroft et al., 2009, Bundschuh et al., 2010, IWA., 2016). These countries adhere to various standards of arsenic in drinking water, ranging from 5 µg/L in the United States to 50 µg/L in most developing countries (Ahmed, 2003, Ravenscroft et al., 2009, Singh and Stern, 2017). Environments 2018, 5(7), 83 Pronounced Antagonism of Zinc and Arsenate on Toxicity to Barley Root Elongation in Soil. The averaged net root elongation (NRE) responses of all of the treatments are shown in Table S4.
The barley NRE in the control treatments of the soils S1 (9.6 ± 1 cm) and S3 (9.1 ± 2 cm) were significantly lower (p < 0.05) than that of S2 (11 ± 1 cm). The lowest single Zn total concentration above which the root elongation was reduced, compared to the control (p < 0.05, Dunnett test), was 1300 mg Zn kg−1 for soil S3, and 2100 mg Zn kg−1 for soils S2 and S1; soil S1 had the highest eCEC.
For the total As single doses, significant NRE inhibition started from 55 mg As kg−1 in S2, the lowest Fe containing soil, and from 604 mg As kg−1 in S1, the soil with highest FeOx concentration.

Introduction Arsenic contamination of drinking water is a serious threat to the health of hundreds of millions of people worldwide (Carlin et al., 2016, Flanagan et al., 2015a, Smith et al., 2016, Zheng and Ayotte, 2015). In the United States (U.S.), for example, forty-three million people use private wells and the United States Geological Survey estimates that ~3 million people in the U.S. drink private well water that contains arsenic levels above the World Health Organization (WHO) standard and U.S. FRONT. MICROBIOL. 14/08/18 Environmental Concentrations of Copper, Alone or in Mixture With Arsenic, Can Impact River Sediment Microbial Community Structure and Functions. Introduction Sediments are an essential component of aquatic ecosystems, as they provide a habitat for many species and thus host a non-negligible biological diversity (Battin et al., 2001).
Within sediments, benthic heterotrophic microbial communities support various ecosystem functions, from organic matter recycling (Schwarz et al., 2007) to pollutant degradation and transformation (Bedard, 2008) and biomass production (Haglund et al., 2003). They are essential for the proper functioning of biogeochemical cycles as well as for ecosystem stability and resilience (Martiny et al., 2013). Sediments are also natural receptors for hydrophobic and persistent pollutants (such as trace metals, polycyclic aromatic hydrocarbons or polychlorinated biphenyls) that can accumulate over time (Bombardier, 2007).
Trace metals, which include metals and metalloids, are ubiquitous and persistent in the environment. Materials and Methods Experimental Design.

PARLEMENT EUROPEEN - Réponse à question E-000644-18 Concentrated zinc and arsenic discharges. An investigation by the University of Huelva published in the Marine Pollution Bulletin, identifies the phosphogypsum ponds in the vicinity of that city as being responsible for the leakage of large concentrations of zinc and arsenic.
The study claims that this situation threatens the Huelva coastline and calls for urgent remedial measures in the ponds which are responsible for large quantities of harmful substances entering the ría. It also indicates that the planned remedial actions are not sufficient to prevent leachate from the phosphogypsum reaching the estuary and claims that the planned decommissioning of the ponds by Fertiberia does not include a final washing process to remove the contaminants. According to the study, the phosphogypsum ponds constitute a source of significant amounts of arsenic and cadmium, among other substances harmful to health. Pollution from mining-related industries is the main source of pollution in the Huelva estuary. BMC PUBLIC HEALTH 27/10/17 A comparison of arsenic exposure in young children and home water arsenic in two rural West Texas communities. This study followed on a formal Health Impact Assessment showing elevated As levels in source well-water supplies of a rural village in the U.S.
Southwest , and aimed to determine whether children in the well-water supplied village (“Community 1”) had elevated blood As levels as compared to children living in a geographically nearby and demographically similar town using a municipal water supply (“Community 2”). The study used ICP-MS for all blood and water sample analysis, a reliable and valid method for accurate detection of low level heavy metals. ICP-MS analysis of blood for determining child As exposure has some advantages over the detection of As in urine.
Urine concentration measures excreted levels of As, and to some extent, these are influenced by child hydration which can fluctuate substantially in dry climates such as the high desert southwest ; blood as compared to urine levels indicate tissue burden .

The material supports laboratories in implementing Commission Recommendation 2015/1381 on the monitoring of arsenic in food. Arsenic is a metalloid which is released in the environment from natural and anthropogenic sources. The toxicity of the element strongly depends on its form: inorganic arsenic is highly toxic (as attested by its popularity in classic crime stories) and the tragic and still ongoing pollution of wells and subsequently food in Bangladesh has received ample coverage in the media. Organoarsenic compounds, however, are less toxic. One of them, arsenobetaine (AB) is the major form of arsenic in marine fish and most other seafood.

Rice and rice products are a significant source of inorganic arsenic in Denmark and the intake is so high that the National Food Institute, Technical University of Denmark, assesses that the intake should be lowered.
Consumers can reduce their risk by eating a varied diet. FOOD_DTU_DK 12/04/16 New method to determine the content of inorganic arsenic in foodstuffs. A new European standard method to determine the content of inorganic arsenic in foodstuffs has been developed at the National Food Institute, Technical University of Denmark. Inorganic arsenic is carcinogenic according to the World Health Organization, WHO. Being able to accurately measure the substance in different foods is necessary to ensure that the content is below the maximum levels recently set by the European Commission to protect consumers. Inorganic arsenic is a substance which occurs naturally in soil, water and certain foods. Rice and rice-based products are the main sources in the Danish diet.

Abstract: Millions of people are exposed to arsenic in drinking water, which at high concentrations is known to cause lung cancer in humans. At lower concentrations, the risks are unknown. We enrolled 196 lung cancer cases and 359 controls matched on age and gender from western Nevada and Kings County, California in 2002–2005. After adjusting for age, sex, education, smoking and occupational exposures, odds ratios for arsenic concentrations ≥85 µg/L (median = 110 µg/L, mean = 173 µg/L, maximum = 1,460 µg/L) more than 40 years before enrollment were 1.39 (95% CI = 0.55–3.53) in all subjects and 1.61 (95% CI = 0.59–4.38) in smokers. Although odds ratios were greater than 1.0, these increases may have been due to chance given the small number of subjects exposed more than 40 years before enrollment.
