  • Should critical levels of plant ozone exposure be lower?

    ‘Critical levels’ of ozone exposure for plants, above which significant adverse effects may occur, are currently calculated by examining ozone’s impacts on only a small number of species. However, researchers have now compared this measure with a new approach which examines all species in a group, and defines the critical levels as the concentration at which 5% of species are ...

  • Estimating exposure to excessive noise in cities

    The 2002 Environmental Noise Directive seeks to provide a uniform basis for measuring and addressing noise pollution, one of the most important urban environmental issues for the EU. New research has assessed city-dwellers' exposure to noise and proposes traffic management strategies to reduce harmful levels. Clear evidence is growing for wide-ranging negative health effects of noise pollution, ...

  • 01dB: How to estimate your noise exposure and your vibration exposure...

    The risk assessment caused by noise and vibration allows the identification of exposed workers and a good knowledge of sound and vibration situations to define an adapted action plan. Many workers are exposed daily to occupational noise and vibration. Extended exposure of individuals to intense noise levels generates hearing loss and important deafness troubles. Regarding vibration levels, it can ...

  • Noise exposure estimation methods compared

    It is difficult to compare estimates of noise exposure across EU Member States because the methods used to produce the data vary between countries. A new study has investigated five methods of estimating noise exposure and identified some of the reasons for variation in the data they produce. In order to comply with the European Noise Directive (END)1, EU Member States have produced ...

  • Update of radiation exposure guidance for the UK

    Scientists at the Health Protection Agency have published their advice to UK bodies following new international guidance on ionising radiation. The International Commission on Radiological Protection (ICRP) published updated recommendations on protection against ionising radiation in 2007. The Health Protection Agency (HPA) has now published its advice on applying those recommendations. Broadly ...

  • Low-Level Arsenic Exposure Before Birth Associated with Early Puberty and Obesity in Female Mice

    The Female mice exposed in utero, or in the womb, to low levels of arsenic through drinking water displayed signs of early puberty and became obese as adults, according to scientists from the National Institutes of Health. The finding is significant because the exposure level of 10 parts per billion used in the study is the current U.S. Environmental Protection Agency standard, or maximum ...

  • Impact of mercury exposure from chlor-alkali plants

    An EU project, EMECAP1, has investigated levels of mercury exposure to populations living near chlor-alkali plants and the impact on human health. It found that the overall health risk was low, but was higher for some workers at the plants and for those who consumed contaminated fish or had mercury dental fillings. Mercury is a natural element but human activities, such as mining and ...

  • Type 2 diabetes may be linked to pesticide exposure

    Cambridge University scientists are advocating more research into the possible links between environmental pollution and type 2 diabetes, the most common form of the disease. At least 171 million people worldwide suffer from diabetes, according to estimates by the World Health Organization. In today's edition of the British medical journal 'Lancet,' Drs. Oliver Jones and Julian Griffin highlight ...
