Air pollution affects tree growth in Sao Paulo

As well as causing significant harm to human health, air pollution also stunts the growth of trees, one of the elements that can attenuate this typically urban environmental problem.  Researchers at the University of São Paulo (USP) in Brazil have shown that atmospheric pollutants restrict tree growth and the ecosystem services provided by trees, such as filtering pollution by absorbing airborne metals in their bark, assimilating CO2, reducing the heat island effect by attenuating solar radiation, mitigating stormwater runoff, and controlling humidity.  The study results have been published in the journal Science of the Total Environment.  Read more...
