How Many Words Does It Take to Make a Book? Editors and agents often quote a word count to writers in order to establish basic parameters. âCasting offâ pages also once was a common practice in which the word count was used to determine how much paper a book would require.

Lead-based paint in the United States. Lead-based paint was widely used in the United States, because of its durability. The United States banned the manufacture of lead-based house paint in 1978 due to health concerns. Lead has long been considered to be a harmful environmental pollutant. Cited cases of lead poisoning date back to the early 20th century.
Different lead compounds are added to the paint as a pigment, creating a specific color depending on whichever compound is used. For example, lead (II) carbonate, known as white lead, makes the paint a white or cream color and the use of lead tetroxide makes a bright red paint. The heavy metal additive also decreases the amount of time that the paint takes to dry, makes the paint more durable, and causes the paint to be more moisture resistant.
