To investigate whether leaves of plane trees (Platanus orientalis) are damaged by traffic pollution, trees from a megacity (Mashhad, Iran) and a rural area were investigated. Soil and air from the urban centre showed enrichment of several toxic elements, but only lead was enriched in leaves. Leaf size and stomata density were lower at the urban site. At the urban site leaf surfaces were heavily...

After considering the particular problems of atmospheric pollution in megacities, i.e. agglomerations larger than 5 mio. inhabitants, with urbanization of World's population going on steadily, possibilities of active biomonitoring by means of green plants are discussed. Based on specific definitions of active and passive bioindication the chances of monitoring heavy metals in Sao Paulo megacity...

Urban development that is geared to the needs of global capital displaces or excludes poorer segments of the population and leads to the social and spatial segmentation of the megacity into citadels and ghettos. This paper considers the future of major metropolitan areas in Africa (large or megacities) and discusses policies and planning strategies appropriate for facing the challenges of their...

Lagos State has grown from 300,000 and 500,000 in 1950 and 1991 to an unprecedented population of 15.7 million (Mabogunje, 2002). Already, it is projected to have a population of 25 million by 2015 which will make Lagos the third largest megacity after Tokyo and Bombay and a population of 29 million by 2020, w ith an annual grow th rate of 8 %( UNCHS, 1996; George, 2010; LWC, 2011). This scenar...
