Arsenic is ubiquitous in the environment and has been classified as a human carcinogen (group I)
The study focuses on inorganic As exposure in rice-based products on sale in Adelaide supermarkets. Almost all rice-based products have been found to contain a good percentage of inorganic As, therefore the health risk posed by consuming rice-based products cannot be ignored for young children. It is crucial to minimize the inorganic As exposure from rice-based diets for young children. To reduce the risk of As, we recommend that young children eat no more than 1 serving of rice-based products per day on average and their diets should include cereals that contain significantly lower levels of As. When manufacturing rice-based products, rice varieties with much less inorganic As should be used to abate exposure to inorganic As.
Abstract: The feasibility of using two important and common clay minerals, kaolinite and montmorillonite, as adsorbents for removal of toxic heavy metals has been reviewed. A good number of works have been reported where the modifications of these natural clays were done to carry the adsorption of metals from aqueous solutions. The modification was predominantly done by pillaring with various polyoxy cations of Zr4+, Al3+, Si4+, Ti4+, Fe3+, Cr3+or Ga3+, etc. Preparation of pillared clays with quaternary ammonium cations, namely, tetramethylammonium-, tetramethylphosphonium- and trimethyl-phenylammonium-, N'-didodecyl-N, N'-tetramethylethanediammonium, etc, are also common. Moreover, the acid treatment of clays often boosted their adsorption capacities. The adsorption of toxic metals, viz., As, Cd, Cr, Co, Cu, Fe, Pb, Mn, Ni, Zn, etc., have been studied predominantly. Montmorillonite and its modified forms have much higher metal adsorption capacity compared to that of kaolinite as well as modified-kaolinite.
