      Dear all,

      A lot of discussion and research is currently taking place regarding the presence of arsenic in rice. While studying the input-output analysis of arsenic in urine samples of individuals after consuming rice, it was observed that certain cases there was a sudden surge in arsenic output. On closer scrutiny, it was found that this surge in arsenic values happened after eggs were eaten.

      A systematic study was undertaken. A procedure was standardized for the determination of arsenic in eggs. The results were very interesting and unexpected. Details of the laboratory experiments, methodology, and results will be communicated in a publication.

      Summary of the findings are:

      1. Arsenic is present in substantial quantities in eggs
      2. All the arsenic is present in the yolk of the egg.
      3. The white of the egg is practically free from arsenic
      4. While the quantity of in samples of eggs from different farms
      varies, an average value of 1750 ppb of arsenic is recorded.
      5. Inorganic arsenic is completely absent
      6. Arsenic is present as the methyl derivative.
      7. Elimination of egg arsenic through urine appears to be faster than
      the arsenic taken through rice.
      8. Since the organic arsenic is converted to ionic arsenic As(III)
      and eliminated via urine there is no worry for individuals with a
      healthy liver.
