Food Additives & Contaminants: Part B, 2013
Rice milk and its by-products were tested for total arsenic concentration. Total arsenic concentration was determined using graphite-furnace atomic absorption spectrometry. The arsenic concentrations ranged from 2.7 ± 0.3 to 17.9 ± 0.5 µg L(-1). Rice milk and its by-products are not clearly defined as food, water or milk substitute.

Association between total ingested arsenic and toenail arsenic concentrations
Journal of Environmental Science and Health, Part A, 2007The association between arsenic exposure from drinking water and toenail arsenic concentrations appears to be non-linear at low exposure levels. To investigate whether this observation is a result exposure misclassification, a dietary exposure assessment was conducted in a cohort of 47 women concurrently enrolled in a prospective longitudinal ...

Determination of total arsenic, inorganic and organic arsenic species in wine
Food Additives and Contaminants, 2002Forty-five wine samples from the south of Spain of different alcoholic strength were analysed for total arsenic and its inorganic [As(III), As(V)] and organic (monomethylarsonic acid [MMAA], dimethylarsinic acid [DMAA]) species. The As levels of the wine samples ranged from 2.1 to 14.6 microg l(-1).

Total and Inorganic Arsenic in Iranian Rice
Journal of Food Science, 2015Abstract It is well known that arsenic (As) exposure, particularly to inorganic species (i‐As), has adverse effects on humans. Nowadays, the European Union (EU) has still not regulated the maximum residue limit of As in commercial samples of rice and rice‐based products, although it is actively working on the topic.

Total and inorganic arsenic in Antarctic macroalgae
Chemosphere, 2007The Antarctic region offers unparalleled possibilities of investigating the natural distribution of metals and metalloids, such as arsenic. Total and inorganic As were analysed in nine species of Antarctic macroalgae collected during the 2002 summer season in the Potter Cove area at Jubany-Dallmann Station (South Shetland Islands, Argentinian Base ...

Dietary contribution to total urinary arsenic in Mexican women
Food Additives & Contaminants: Part A, 2022Exposure to inorganic arsenic (iAs) damages health in many ways. The main routes of human exposure are consumption of contaminated water and diet, but evidence regarding the dietary contribution of iAs is limited. The objective of this work was to determine the foods and beverages that contribute to urinary total arsenic levels (TAs).

The determination of arsenic(III) and total arsenic by atomic-absorption spectroscopy
The Analyst, 1976In the atomic-absorption determination of arsenic by the hydride evolution method with sodium borohydride, maintenance of the pH between 4 and 5 permits the selective determination of arsenic(III) in mixtures of arsenic(III) with arsenic(V). Total arsenic can be determined separately by evolution from 5 M hydrochloric acid.

Heavy Metal, Total Arsenic, and Inorganic Arsenic Contents of Algae Food Products
Journal of Agricultural and Food Chemistry, 2002The total arsenic, inorganic arsenic, lead, cadmium, and mercury contents of 18 algae food products currently on sale in Spain were determined. The suitability of the analytical methodologies for this type of matrix was confirmed by evaluating their analytical characteristics. The concentration ranges found for each contaminant, expressed in milligrams

The dietary intake of total arsenic (tAs), inorganic arsenic (iAs) and total mercury (tHg) in lunch and breakfast servings provided by the Chilean School Meal Program (SMP) was estimated, using the duplicate-portion variant of the total diet study. Lunch and breakfast samples were collected from 65 schools throughout the country in 2006.

Electrochemical methods for the determination of total arsenic and arsenic compounds
Applied Organometallic Chemistry, 1992AbstractThe determination of total arsenic and of arsenic compounds in biological and inorganic samples is a task frequently encountered by analysts. Several elecrochemical methods have been developed for the determination of total arsenic (generally after mineralization of the sample), arsenite, arsenate, methylarsonic acid and dimethylarsinic acid ...
