TL;DR: The present status of knowledge of the gas phase reactions of inorganic Ox, Hox and NOx species and of selected classes of volatile organic compounds (VOCs) and their degradation products in the troposphere is discussed in this paper.
2,722 citations
TL;DR: In this paper, the status of fat and oil derived diesel fuels with respect to fuel properties, engine performance, and emissions is reviewed, and it is concluded that the price of the feedstock fat or oil is the major factor determining biodiesel price.

Abstract: This paper outlines the history of air pollution in the UK, describes the types of pollutant now in the atmosphere, and discusses the relation between air pollution and health. The primary pollutants, which are directly discharged into the atmosphere, often from vehicle exhaust emissions, are: (1) sulphur dioxide (SO2); (2) nitrogen oxides (NOx); (3) smoke and particulates; (4) carbon monoxide (CO); (5) carbon dioxide (CO2); (6) organic compounds; and (7) metals, especially lead and calcium. The secondary pollutants, derived from primary pollutants, by chemical changes, include: (1) ground ozone, an important constituent of photochemical smog; and (2) acid aerosols. It is now proved beyond reasonable doubt that sufficiently high concentrations of atmospheric pollution have severe health effects. Various biological and medical methodologies can be used to evaluate their effects on health. Asthma and rhinitis are two important respiratory diseases, whose causes include air pollution. For the covering abstract see IRRD 869702.

TL;DR: A review of insights derived from photochemical models and field measurements can be found in this paper, where the ozone-precursor relationship can be understood in terms of a fundamental split into a NOxsenstive and VOC-sensitive (or NOx-saturated) chemical regimes.
