Sandi - La Leche League International has a number of good articles about bf and contaminants. There is an article by Betty Crase on pesticides and breast milk at: http://www.lalecheleague.org/llleaderweb/LV/LVMayJun94p37.txt You can also find an article entitled "Breastfeeding Remains Best Choice in a Polluted World" at http://www.lalecheleague.org/Release/ReleasePollution.html And finally there is a Greenpeace press release and the LLLI response at: http://www.lalecheleague.org/Release/Earth97.html http://www.lalecheleague.org/Release/EarthDay.html I think these will help you. Do you all know that the LLLI web site has a lot of bf information? Check it out at: http://www.lalecheleague.org/ Cynthia D. Payne LLL of Berkshire County Mass
