Using trees as urban heat island reduction tool in Enugu city Nigeria based on their air pollution tolerance index

摘要: The Study examined the air pollution tolerance indices (APTI) of five plant species around Enugu urban area. Four physiological and biological parameters including leaf relative water content (RWC), ascorbic acid (AA) content, total chlorophyll (TCh), extract pH were used to develop an APTI. vegetation monitoring in terms its APTI acts as a ‘Bioindicator’ can be incorporated into assessment studies for selecting trees heat island (UHI) mitigation strategy. result showed order Anacarduim occidentale (22.20), Pinus spp (22.35), Catalpa burgei (22.57), Mangifera indica (23.37), Psiduim guajava (24.15). A comparative analysis was also done between shedding ability these their that best tree provides both shed high appeared order: guajava, Magifera indica, burgei, occidentale. results such are therefore handy future planning, well provide tolerant landscape mitigation.
