Cockatiel I live in Pennsylvania My name is Bonnie	Threats of Toxicity in Newspaper Ink There are three ways ink can have contact with the human body. There is dermal absorption (through the skin), inhalation of ink particles into the respiratory tract (breathing), or ingestion through the mouth and into the digestive system (eating). There is little threat of dermal absorption of ink or its ingredients once the ink is dry because the ink has achieved its stable state. The ingredients that were potentially absorbable become dry and are no longer able to be absorbed. Lead, which can be absorbed through the skin, was banned as an ingredient in ink by the EPA in 1985 and is, therefore, no longer a threat. Stall trials concluded that the ink rub-off from printed newsprint was not a concern for animals. Inhalation is a concern only when the ink is in liquid form either in transportation or at the place of production. Particle droplets and evaporation of active ingredients are a concern because they can be inhaled if proper prevention techniques are not practiced during the printing of the newspapers. Again, however, once the ink is applied to the paper and dried, it is stable and there is little danger of inhaling ink particulates. There is a threat of inhalation of dust from finely shredded paper. In this case, the concern is over fibrous inhalation rather than the toxicity. To avoid fibrous inhalation, stall trial results suggest using shreds at least 1 inch x 1 1/2 inch or larger. Ingestion of inks used on newsprint has not been an issue because the ingredients used in the inks are not considered toxic in either the liquid or dry state. The only animal that showed an indication of grazing on the newspaper bedding was the horse and the grazing was in limited amounts. No other animals indicated any interest in the newsprint as a food source. These trials and ink references are for the black inks used in newsprint. The trials do not include the waxed or glossy inserts or supplements that accompany newspapers, nor does it include colored inks used on those publications.
