Arsenic (As) and Antimony (Sb) are toxic heavy metals that often associated in contaminated environment. High As concentration is reported in Chelpo, Khorasan province, northeast Iran. This study examined the possibility of As and Sb in rhizofiltration by common reed, Phragmites australis .

Arsenic and health

What is arsenic? Arsenic is a substance that is found naturally in rock, often near gold deposits. It has been used to kill insects that attack animals, timber, vegetables and fruit. In some situations, arsenic harms people's health. How does arsenic enter and leave

In situ metal stabilisation by amendments has been demonstrated as an appealing low-cost remediation strategy for contaminated soil. This study investigated the short-term leaching behaviour and long-term stability of As and Cu in soil amended with coal fly ash and/or green waste compost. Locally abundant inorganic (limestone and bentonite) and carbonaceous (lignite) resources were also

In contrast to nitric oxide, which has well established and important roles in the regulation of blood flow and thrombosis, neurotransmission, the normal functioning of the genitourinary system, and the inflammation response and host defense, its oxidized metabolites nitrite and nitrate have, until recently, been considered to be relatively inactive. However, this view has been radically

Arsenic (As) analyzed by implementing ISO 11969:1996 methodology which employs absorption spectrometry (hydride technique) [24]. For TOC estimation HACH 10129 protocol was adopted. Heavy molecular chain hydrocarbons derived from fuel oils, analyzed by APHA 5520 Β/APHA 5520 F [25] and US-EPA, 1664 (2010) methodology [26].

Removal of carcinogenic and toxic arsenic from wastewater is essential for the safety of water that may be used for irrigation or drinking. In this study, three different of indigenous arsenic resistant bacterial strains were isolated from gold mine environment, Bacillus thuringiensis strain WS3, Pseudomonas stutzeri strain WS9, and Micrococcus yunnanensis strain WS11.

Urinary arsenic species are important short-term biomarkers that have been used in epidemiological studies. However, the stability of soluble arsenic species and the amount of arsenic lost during sample pretreatment remain unclear. The objective of this study is to evaluate the stability of soluble arsenic species in urine and aqueous standards, as well as to assess the amount of insoluble and

Abstract The objectives of this study were (1) to compare the bioavailability of arsenic (As) to plants in an As-spiked agricultural soil and a naturally contaminated mine tailings, (2) to compare the theoretical ability of various chemical amendments to solubilise As in naturally contaminated mine tailings, and (3) to examine the ability of Brassica juncea (Indian mustard) plants to remove

Arsenic release was determined by residual composition and predominant arsenic species, but was also highly impacted by pH, counter-ion, and the presence of competing ligands. More favorable arsenic retention was generally achieved with iron-based residuals, with arsenate compared to arsenite, and at pH values approaching neutrality.

2014/4/24The maximum removal efficiency of both arsenic species was obtained at pH = 5 0.1 and starched nanoparticles was effective in slightly acidic and natural pH values. The adsorption kinetics fitted well with pseudo-second-order model and the adsorption data obeyed the Langmuir equation with a maximum adsorption capacity of 14 mg/g for arsenic (V), and 12.2 mg/g for arsenic (III).
