  • Air Pollution Affects Tree Growth in São Paulo

    As well as causing significant harm to human health, air pollution also stunts the growth of trees, one of the very 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 was supported by FAPESP. The results have been published in the journal Science of the Total Environment.

    “We found that in years when levels of particulate matter in the atmosphere were higher, for example, the trees grew less. As a result, they started later in their lives to provide ecosystem services that play an important role in reducing urban pollution and mitigating or adapting the city to climate change,” said Giuliano Maselli Locosselli, a postdoctoral researcher at the University of São Paulo’s Bioscience Institute (IB-USP) with a scholarship from FAPESP and first author of the study.

  • Transfer of EU Powers Leads to Silent Erosion of UK Pesticide Regulation

    New analysis by the UK Trade Policy Observatory is warning that what should have been the technical formality of transferring EU powers into national law when the UK leaves the European Union, could instead open the gates for the widespread use of outlawed carcinogenic pesticides that have been shown to alter human reproductive, neurological, and immune systems.
