HEMICALS

Water has physical hemical properties that are very different from those of other solvents [1] and its role in enhancing the reactivity and selectivity of some organic reactions is still a debated question. Recent experimental studies [3e, 9] and computer simulations [10] seem to indicate, at least with respect to the rate enhancement of aqueous Diels Alder reactions, that the main effects are due to the enforced hydrophobic interactions and hydrogen bond interactions. 

A classification of the causes of hypoxia is presented in Table II. Only anoxic anoxia (due to decreased ambient oxygen or to respiratory disease) has arterial P02 values decreased (with accompanying decreased venous P02 values). However, hemic, ischemic, and histoxic hypoxia may be present (termed non-ventilatory hypoxia) with normal arterial P02 values. Thus the best evaluation of hypoxia is an analysis of both arterial and venous... 

Eye irritation has been a common complaint of people exposed to phohx hemical air poUution. Attempts to investigate this experimentally have encountered problems, because of the subjective nature of the human response and the multiphasic photochemical reactions involved. Human studies conducted until 1970 on eye irritation were cataloged and discussed in Air Quality Criteria for Hydrocarbons.
