This book presents advanced methods to analyse and clean pollutants, such as nanotechnology to treat water, techniques to remediate building materials, and bioindicators. It is very important that the understanding of these methods are brought to the attention of scientists, as cities and ecosystems are still polluted by toxic compounds despite efforts to clean the planet.
