SCHALK - WSCHA As you know, there has been work by rarious selentlsts In regard to finding polychlorinated biphenyl in etarine life. There will certainly be none work on this, both in the U,S. and in Europe! One of the problems is that PCS can be detected in parts per billion. Although there are no known harmful effects at these low levels, there are probably some uses that could be questioned and would be hard to defend. One auch use would be in paints for the interior of water towers, where the water is primarily for human consumption. Howard Bergen was under the impression we were asked about this specific use several years ago and did approve it. Do we know of any customers formulating paints specifically for water towers? Hi'T .Mil p-uvlJ- /vw J.UE.
