Hyperaccumulation of elements in plants has been previously defined as an element-
specific behaviour resulting in concentrations in foliar dry mass that are at least two orders of …

Dietary intake/status of the trace mineral Se may affect the risk of developing hypertensive
conditions of pregnancy, ie pre-eclampsia and pregnancy-induced hypertension (PE/PIH). In …

Brazil nuts are the fruit of the enormous tropical tree Bertholletia excelsa that are produced
in and exported from the territory of the Amazon. As a natural rich source of selenium (Se) …

The concentrations of selenium, barium, and radium were determined in Brazil nuts grown in
four regions: Brazil, Bolivia, Peru, and an unknown locality assigned to northern South …

Selenium (Se) intake is generally from food, whose Se content depends on soil Se and plant
accumulation. For humans, adequate Se intake is essential for several selenoenzymes. In …

This work presents an investigation of the activity concentration (AC) of naturally occurring
radionuclides in 26 samples of seasoning and nuts utilized for Brazilian population. The …

Although natural radionuclides are always present in foods, information about the levels is
scarce. The diet-related exposure to radiation is, however, dependent on the radionuclide …

Summary Calcium, strontium, barium, Ra 228 and Ra 226 were measured in tissues of the
Brazil nut tree from different areas; ammonium acetate extracts of the underlying soil were …

This paper presents the results of a literature search to identify information on concentrations
of 'background'radioactivity in foodstuffs and other commonly available environmental …

Brazil nuts are well known for their extraordinarily high selenium content. For this reason,
they are frequently recommended as a kind of natural selenium 'supplement', particularly for …
