Chapter 8: Haber's Law and its Application to Combustion Products¹

Haber's Law has long played an important role in toxicological thinking for calculation of acute toxicity and, in its original (Ct=k) or modified (Cⁿt=k) forms, underlies much work in the standard setting field, including the development of emergency planning guidelines and workplace exposure limits for some of the individual gases released in combustion products. This chapter describes the history of the development of Haber's Law and its derivatives. The extent to which these can be applied effectively to combustion products is examined. Several cases have been described for which the development of more sophisticated calculation models has been necessary for key combustion gases.
