“…In particular, the high observed As concentrations in seafood are within values presented in the relevant literature (Storelli et al , ; Afonso et al , ). Similarly, the low As levels in other food groups, such as vegetables, agree with literature concerning samples from not heavily polluted areas (Ciminelli et al , ; Upadhyay et al , ). In contrast, marine organisms are known to be very efficient accumulators of As, reaching levels in the 1–100 mg kg −1 range.…”

Summary On the basis of a Total Diet Study, the Br, As, Cd and Pb contents in relevant food groups consumed in Portugal were determined. The studied groups were meat products, fatty fish, lean fish, shellfish, cephalopods, fresh and dried fruit, crucifers and other vegetables. It was observed that the concentrations of As, Br, Cd and Pb in fruit, vegetables and meat products were much lower than in seafood. Fresh fruit exhibited the lowest elemental contents. The concentrations of As, Br, Cd and Pb did not show any dependence on season. With respect to proximate composition, elemental content dependence on protein or ash was weak. PCA showed relevant associations: between Br and ash contents in fatty fish; between Cd, Pb and protein contents in crucifers; and between As, fat and protein contents in the other vegetables group. Therefore, the effect of the proximate composition on the studied elemental contents warrants investigation.

“…In developing countries, As compounds are widely utilized in agriculture as herbicides, pesticides, and insecticides as sodium arsenate, calcium arsenate, cacodylic acid, and other compounds. Therefore, the use of Ascontaining chemicals in agriculture transfers this toxic metal into food of both animal and vegetable origin (Han et al 2003;Upadhyay et al 2019). Millions of people worldwide are significantly exposed to high As levels contained in meat, fish, grains, and vegetables, health supplement products (herbal-based medicines), as well as through food that has been processed using As contaminated water.…”

Arsenic intoxication: general aspects and chelating agents

et al. 2020

Arsenic (As) is widely used in the modern industry, especially in the production of pesticides, herbicides, wood preservatives, and semiconductors. The sources of As such as contaminated water, air, soil, but also food, can cause serious human diseases. The complex mechanism of As toxicity in the human body is associated with the generation of free radicals and the induction of oxidative damage in the cell. One effective strategy in reducing the toxic effects of As is the usage of chelating agents, which provide the formation of inert chelator-metal complexes with their further excretion from the body. This review discusses different aspects of the use of metal chelators, alone or in combination, in the treatment of As poisoning. Consideration is given to the therapeutic effect of thiol chelators such as meso-2,3-dimercaptosuccinic acid, sodium 2,3-dimercapto-1-propanesulfonate, 2,3-dimercaptopropanol, penicillamine, ethylenediaminetetraacetic acid, and other recent agents against As toxicity. The review also considers the possible role of flavonoids, trace elements, and herbal drugs as promising natural chelating and detoxifying agents.

The effect of precursor speciation on the growth of scorodite in an atmospheric scorodite synthesis

In this study, we propose a growth pathway of scorodite in an atmospheric scorodite synthesis. Scorodite is a non-direct product, which is derived from the transformation of its precursor. Different precursor speciation leads to different crystallinity and morphology of synthesized scorodite. At 10 and 20 g l −1 initial arsenic concentration, the precursor of scorodite is identified as ferrihydrite. At 10 g l −1 initial arsenic concentration, low arsenic concentration is unfavourable to the complex between arsenate and ferrihydrite, inhibiting the transformation of ferrihydrite into scorodite. The synthesized scorodite is 1–3 µm in size. At 20 g l −1 initial arsenic concentration, higher arsenic concentration favours the complex between arsenate and ferrihydrite. The transformation process is accessible. Large scorodite in the particle size of 5–20 µm with excellent crystallinity is obtained. However, the increasing initial arsenic concentration is not always a positive force for the growth of scorodite. When initial arsenic concentration increases to 30 g l −1 , Fe(O,OH) 6 octahedron preferentially connects to As(O,OH) 4 tetrahedron to form Fe H 2 As O 4 2 + or FeHAs O 4 + ion. Fe–As complex ions accumulate in solution. Once the supersaturation exceeds the critical value, the Fe–As complex ions deprotonate and form poorly crystalline ferric arsenate. Even poorly crystalline ferric arsenate can also transform to crystalline scorodite, its transformation process is much slower than ferrihydrite. Therefore, incomplete developed scorodite with poor crystallinity is obtained.
