It also covers all the main phytotoxic pollutants with due consideration given to impacts at all levels of plant organisation from molecular to ecological. The book emphasises the effects of air pollutants in altering plant response to common stresses, both abiotic and biotic - fields in which considerable progress has been made since publication of the first edition. It includes coverage of how research leads to pollution control policy development. It is essential reading for students in Environmental Science, Biological Science and Agriculture, as well as environmental consultants and professionals involved in air quality research and the application of air quality guidelines and advice.
