Hence, the average age of the air pollution related fatalities is much higher than for victims of fatal road accidents (30-40 years of age). Theoretical as well as empirical evidence indicates a decreasing WTP with increasing age, with reduced remaining life expectancy and with reduced quality of life. For the present study, the relationship adopted is provided by the latest research of Jones-Lee. 21 Weighting the age structure of the fatalities due to respiratory and cardiovascular disease and lung cancer in all three countries by the age factor, an average adaptation factor of 61% is obtained for the present willingness-to-pay for a prevented fatality value. Based on the preceding. | Jones Bartlett Learning LLC.

INTRODUCTION HISTORY Air pollution has two histories an early unrecorded one and a more recent recorded one. By examining these histories one can gain a broad perspective on air pollution including its trends and the relationship between the evolution of human technology and air pollution exposures. History also allows US to understand the way our current ideas about air pollution and its hazards might have developed and how our regulations and controls came about. Early History and Natural Events About 4 billion years ago in the Hadean era the surface of the newly-formed Earth went through a violent period characterized by intense bombardment from meteorites frequent volcanic eruptions boiling seas and extreme ultraviolet radiation exposure. These conditions would certainly have precluded the complex and .
