Total As and As Speciation in Italian Rice as Related to Producing Areas and Paddy Soils Properties
Rice
and rice-based foodstuffs are important pathways for inorganic
As dietary intake. This work shows a detailed picture of As content
and speciation in Italian rice, which contributes to more than one-half
of the European production, and addresses the role of soil chemistry
and agronomic management on As concentration in rice grain, in view
of ameliorative strategies. The mean total As content in Italian white
rice was 155 ± 65 μg kg<sup>–1</sup> with significant
differences among producing areas, while the mean inorganic As was
102 ± 26 μg kg<sup>–1</sup>, largely below the E.U.
limit of 200 μg kg<sup>–1</sup> for white rice, although
part of the production would not be suitable for baby food production,
which requires less than 100 μg kg<sup>–1</sup> of inorganic
As. The differences in As content and speciation in rice among the
studied areas resulted from the complex interactions of soil, plant,
and anthropic factors. Among others, Si nutrition seemed to play a
key role in regulating As transfer from soil to plant
MyDas Architecture.
<p>The requesters can interact with MyDas through the servlet, which communicates the commands to the Controller. The Controller knows which Data Sources have been implemented by querying the Configuration Manager. Data Sources should implement at least one of the provided Interfaces. MyDas internally implements the DAS model.</p
