. The soil of amenity areas is important in the urban landscape. Some is natural, some is man‐made. Both contribute greatly to the environment of our cities through the grass, shrubs and trees which they support. Results of research from agriculture and urban gardens have been extrapolated in this review to consider the significance of toxic metals in amenity soil. The metals of most concern for plant growth are zinc, copper and nickel as they are phytotoxic, but additionally lead, cadmium, arsenic, and mercury are of concern due to their effects on human health. The currently acceptable threshold values for metals in the soil of public open spaces, playing fields and parks are presented, and consideration is given to the toxic metal content of an assortment of materials likely to be used in constructing amenity soil.
