Artificial turf, a surface of synthetic fibres made to look like natural grass, is increasingly being used in places like sports fields, child care facilities and streetscapes. It is also used in play areas, residential/commercial landscaping, roadway medians, bases of street trees, rooftop decks, and patios, balconies around swimming pools, pet areas and airports. Toronto Public Health completed a health impact assessment to better understand the potential implications of this increase in use.
