     1        renewed interest in monomer migration.  There have been
              six world symposiums on the topic.  The latest was held in
     2        1990 in London, England.  Over the years it appears that
              physical chemists have shown considerable interest in
     3        migration".
 
     4        We skip ahead to the next paragraph. We note the last
              sentence:  "In packaged foods with the addition of heat
     5        (such as microwave temperatures) vitamin A will decompose
              and produce m-xylene, toluene, and
     6        2,6-dimethylnaphthalene.  Toluene will aggressively
              dissolve polystyrene and render  polystyrene as an
     7        unsuitable package for containing or microwaving products
              that contain vitamin A."
     8
         Q.   What products contain vitamin A for example?  Would that
     9        include for example lemon?
              A.  Lemon, I would say -- I am not a nutritionist;
    10        I cannot answer that question.
 
    11   Q.   Are there any other bits you want to refer us to?  The
              next paragraph?
    12        A.  No, I would skip to the first paragraph on the next
              page.
    13
         MR. JUSTICE BELL:  Just pause a minute.
    14
         MR. MORRIS:  I do not know if you want to quote the next two
    15        paragraphs but they seem to talk about the taste can be
              detected of styrene?
    16        A.  Yes.  I will not then.  But they essentially say you
              can actually taste styrene in a food container, in the
    17        food product that is contained in a styrofoam food
              container; this has actually been acknowledged by the
    18        plastics packaging, by at least one plastics packaging
              trade group; and I will refer to that document in more
    19        detail.  But essentially if we move to ----
 
    20   Q.   Are there any other bits you want to refer us to then in
              this document because I just noticed ----
    21
         MR. JUSTICE BELL:  Is there any one of these papers in the
    22        bibliography there which actually says styrene from
              polystyrene foam cups?
    23        A.  From food packaging?
 
    24   Q.   Does actually migrate into the drink or food?
              A.  That is what I would refer you to, page 5, the second
    25        to last paragraph:  "Though migration of styrene monomer
              into foods has been shown to occur", then it refers to 
    26        four particular studies.  I will read their titles: 
              K. Figge, "Migration of Additives from Plastic Films into 
    27        Edible Oils and Fat Stimulants; Garcia Melian -- I will
              not read their names -- "Total Migration From Plastic
    28        Yoghurt Pots" which is a Spanish document; Joseph Miltz,
              which was an earlier  -- number 19 on page 13 of the
    29        references:  "Migration of Low Molecular Weight Species
              from Packaging Materials:  Theoretical and Practical
    30        Considerations"; and number 31 "Migration of Packaging
              Components to Food:  Regulatory Considerations".
