Is rice milk poisonous?
Children should not drink rice milk because it can contain harmful levels of arsenic, scientists have warned. The poison is found naturally in low levels in rice and other plants. Levels can be boosted by the way rice is grown in flooded paddies and by the presence of traces of old pesticides.
Is there arsenic in cheese?

Is arsenic a metalloid?
Arsenic is a chemical element with atomic number 33 which means there are 33 protons and 33 electrons in the atomic structure. The chemical symbol for Arsenic is As. Arsenic occurs in many minerals, usually in combination with sulfur and metals, but also as a pure elemental crystal. Arsenic is a metalloid.
What are BMDS and bmdls and why are they important?
Typically, a BMR near the low end of the observable range is selected as the basis for obtaining BMDs and BMDLs to serve as potential PODs for deriving quantitative estimates below the range of observation and to use for comparisons of effective doses corresponding to a common response level across chemicals, studies, or endpoints.
What is BMDL in benchmark model?
Benchmark dose modelling (BMDL) From those models considered compatible with the data (i.e. that pass the goodness-of-fit test) the lowest BMDL is typically used as the RP/POD. At least 2 test groups and a control, together with a dose-response relationship, are needed in order to use this approach.
