The Physiological Effects of Air Vitiated by Respiration is a seminal work on the impact of air quality on human physiology. Smith and Haldane conducted pioneering experiments on the effects of carbon dioxide levels on human respiration, circulation, and other bodily functions. Their work laid the foundation for the modern study of indoor air quality and the importance of ventilation in maintaining healthy living and working environments. This book is a must-read for anyone interested in the history of public health and environmental science.
