Fate of polychlorinated biphenyls, metals, and other elements in papers fed to lactating cows

When lactating cows were fed 30% of either newspaper, Brown or gray cardboard, or computer paper as a cellulose substitute in their ration for up to 38 days, PCB's, present perhaps as ink dye carriers in the paper, were excreted in milk up to levels of 76 ppb and stored in tissues such as renal...

Description
Summary:When lactating cows were fed 30% of either newspaper, Brown or gray cardboard, or computer paper as a cellulose substitute in their ration for up to 38 days, PCB's, present perhaps as ink dye carriers in the paper, were excreted in milk up to levels of 76 ppb and stored in tissues such as renal fat up to levels of 1540 ppb. Differential metabolism and storage of certain PCB's were indicated. Milk production declined 20-33% during the paper feeding experiment, but this could have been due to the end of the lactation period.
