While this book from the Industrial Hygiene Research Laboratory of the National Institute of Health is concerned chiefly with industrial poisoning and says practically nothing about children, it should not be overlooked by any one who wishes to make a thorough study of carbon monoxide poisoning.
The chemistry is thoroughly covered. The sources of carbon monoxide poisoning given are mostly those in industry. Those that might concern children are the various gas-fired heaters, furnaces and coal stoves. Automobile exhausts, gas leaks and charcoal heaters also contribute to the fatalities. Although the toxic properties of illuminating gas are mainly due to its content of carbon monoxide, it is more acutely toxic than this content would indicate.
Studies have been made of the concentration of carbon monoxide in city streets. Even in crowded traffic and even with continued exposure the concentrations are below the dangerous levels. Studies made on 156 traffic officers
