Exposure to traffic-related air pollution at school, where children spend much of their waking hours, has been associated with poorer performance in tests of brain health and development.

This study (the first of its kind in Australia) aimed to assess associations between greenery, road traffic density surrounding primary schools, and academic achievement of primary schoolchildren in Melbourne. There is preliminary evidence that greenery/greenspace around schools may be positively associated with children's cognitive development and academic outcomes, whereas traffic-related air pollution may have a detrimental effect. Preliminary evidence indicated that greenery around primary schools was positively associated with Reading, Numeracy and Grammar & Punctuation scores.
