“…Arsenik dünyanın farklı bölgelerinde toprakta ve suda geniş bir aralıkta bulunmaktadır [21]. Türkiye'nin de içerisinde yer aldığı dünyanın birçok ülkesinde (ABD, Arjantin, Bangladeş, Şili, Hindistan, Meksika, Çin, Moğolistan, Myanmar, Nepal, Yeni Zelanda, Tayland, Vietnam ve Tayvan gibi) çoğu içme ve kullanma suyu kaynağında, arsenik derişimi ulusal ve uluslararası içme suyu standartlarının üzerindedir [8], [17], [22], [23].…”

GirişArsenik (As) ile kirlenmiş yeraltı suları içme ve kullanma suyu olarak kullanılmasının yanında, sulama suyu olarak da kullanılmaktadır. As içeren su ile sulanan bitkiler, doğrudan insanlar tarafından tüketilmekte veya bu bitkilerin otcul hayvanlar tarafından tüketilmesi ile besin zinciri yoluyla insanlara ulaşmaktadır. Özellikle As ile kirlenmiş toprak ve yeraltı suyunun bulunduğu bölgelerde yaşayan insanlar arseniği bünyelerine beslenme yoluyla (su, bitki ve hayvansal gıda) almaktadır. En yüksek güvenli As alım seviyesi (içme suyundan ve besinlerden) orta yaştaki bir erkek için 220 mg/gün olarak tanımlanmıştır [1].İçme suyunda, As derişiminin kısıtlanması ile As giderimine yönelik araştırma sayısında artış olmasına rağmen ülkemizde, içme ve kullanma suyu kaynaklarında, As kirliliği araştırmaları oldukça sınırlı sayıdadır. Atropojenik (yapay) yollarla sular, As kirlenmesine maruz kalırken, jeotermal kaynaklı suların kullanımı ile de su kaynaklarında As kirlenmesi belirlenmiştir. Doğal ve yapay yollarla As kirlenmesine maruz kalan toprak ve sulama sularının tarımsal amaçlı kullanımı ve etkileri hakkında ülkemizde çalışma bulunmamaktadır.Hayvan beslenmesinde temel gıda maddeleri olan hayvan yemi ve suyun kalitesi hakkında araştırmalar oldukça sınırlıdır. Hayvansal ürünlerde (et, sakatat ve süt) biriken kirleticiler (özellikle ağır metaller) besin zinciri yoluyla insanlara

“…The problem is a natural source of arsenic. Increased concentration of arsenic in water, as a result of water-rock interaction, is present in many countries, among others in Chile (Bugueno et al 2014), China (He and Charlet 2013), Hungary (Rowland et al 2011), America (Sorg et al 2014), and Japan (Kondo et al 1999). In natural waters, arsenic is usually present as inorganic As(III) and As(V).…”

Composite material Zr-doped TiO2, suitable for the removal of arsenic from water, was synthetized with fast and simple microwave-hydrothermal method. Obtained material, Zr-TiO2, had uniform size and composition with zirconium ions incorporated into crystal structure of titanium dioxide. Synthetized composite material had large specific surface area and well-developed micropore and mesopore structure that was responsible for fast adsorption of As(III) and As(V) from water. The influence of pH on the adsorption capacity of arsenic was studied. The kinetics and isotherm experiments were also performed. The treatment of natural water sample containing high concentration of arsenic with composite material Zr-TiO2 was efficient. The concentration of arsenic was reduced to the value recommended by WHO.

“…Arsenic exists primarily in 2 inorganic species: As(V), predominating in oxygenated waters, and As(III), prevailing in reducing conditions [3]. The As(III) form is more toxic and mobile than As(V) and can be readily oxidized to As(V) on exposure to air [4].…”

The rapid redox transformation of arsenic (As) species in waters presents a great environmental challenge in the accurate determination of its concentration and toxicity. The motivation of the present study was therefore to develop a method for rapid on-site separation of As(V) and As(III) in various aqueous matrices. The authors synthesized a thiol-modified sand (T-sand) that selectively removed As(III) but did not adsorb As(V). The novel application of this T-sand in a disposable cartridge was able to successfully separate As(V) (37-970 µg L(-1) ) and As(III) (not detected to 488 µg L(-1) ) in 23 groundwater samples collected in areas with naturally occurring As. The As speciation results determined with T-sand separation in the field were consistent with those obtained using high-performance liquid chromatography-atomic fluorescence spectrometry. Furthermore, the T-sand cartridge was applicable in a wide variety of matrices, including groundwater, leachants of the toxicity-characteristic leaching procedure, and extracts from the California waste extraction test; sequential extraction test; and in vitro gastrointestinal extraction. This easy-to-use separation method is especially suitable for routine field monitoring of As speciation.
