This book presents the recent findings on air quality in Africa from the virtual event of the first International Conference on Air Quality in Africa (ICAQ 2022), providing a comprehensive overview on many subjects of air pollution that affect African society. It highlights research progress in the chemical and physical characterization of air pollutants, their related respiratory and non-respiratory health effects, measurements and monitoring of air pollutants using satellite remote sensing and modeling techniques, currently implemented abatement policies in different African countries, existing research and networking infrastructures, and novel tools for monitoring air quality. The advances in the development of local cost-effective air quality monitoring tools in Africa as well as the use of low-cost sensors in quantifying air quality levels are presented. This book is an enrichment for researchers, experts, and advocates of air quality, atmospheric chemistry and physics, satellite remote sensing applications, and policymakers in Africa.

Prepared by an international team of eminent atmospheric scientists, Mechanisms of Atmospheric Oxidation of the Oxygenates is an authoritative source of information on the role of oxygenates in the chemistry of the atmosphere. The oxygenates, including the many different alcohols, ethers, aldehydes, ketones, acids, esters, and nitrogen-atom containing oxygenates, are of special interest today due to their increased use as alternative fuels and fuel additives. This book describes the physical properties of oxygenates, as well as the chemical and photochemical parameters that determine their reaction pathways in the atmosphere. Quantitative descriptions of the pathways of the oxygenates from release or formation in the atmosphere to final products are provided, as is a comprehensive review and evaluation of the extensive kinetic literature on the atmospheric chemistry of the different oxygenates and their many halogen-atom substituted analogues. This book will be of interest to modelers of atmospheric chemistry, environmental scientists and engineers, and air quality planning agencies as a useful input for development of realistic modules designed to simulate the atmospheric chemistry of the oxygenates, their major oxidation products, and their influence on ozone and other trace gases within the troposhere.
