  • Childhood obesity linked to traffic pollution

    Traffic pollution contributes to childhood obesity, a recent study concludes. In the US investigation of over 4 500 children, the researchers estimated that air pollution increased the body mass index (BMI) of 10-year olds in the most polluted areas of study by 0.4 units, compared to those in the least polluted areas. It is thought that pollution may have slowed the children’s metabolism. ...

  • Traffic pollution hotspots to be revealed ‘live’ in London

    A pioneering network of sensors could make the traffic build-ups that cause pollution hotspots a thing of the past. The ‘Pioneers 09’ showcase event on March 4th will be the first time that real-time data from the network has gone on public display. ‘Pioneers 09’ is being held at the Olympia Conference Centre in London and organised by the Engineering and Physical Sciences Research Council ...

  • Air traffic management to balance CO2 emissions and noise pollution

    Speed constraints for aircraft are put in place, at some airports, to minimise noise pollution in local areas, however, such practices can be very fuel-inefficient. New research has now shown that relaxing departure speed limits could substantially reduce CO2 emissions, while maintaining acceptable noise levels. The aviation industry is a major contributor to emissions of greenhouse ...

  • Traffic pollution associated with risk of developing type 2 diabetes

    Long-term exposure to traffic-related air particle pollution is linked with type 2 diabetes, a new study in Germany has found. Furthermore, the study found that people living close to busy roads were at greater risk of developing the disease than those living further away. Air pollution has been linked to a number of health problems, including heart, circulatory and lung diseases. It has also ...

  • Air pollution from road traffic can raise blood pressure

    High blood pressure is linked to long-term exposure to traffic-related air pollution, new research suggests. After accounting for lifestyle factors, socioeconomic status and pre-existing health conditions, the researchers found that a rise in traffic emissions of nitrogen dioxide corresponded to a rise in blood pressure of exposed individuals. Long-term exposure to air pollution has previously ...

  • Living close to heavy traffic strongly linked to heart disease deaths

    A strong link between long-term exposure to vehicle pollution and deaths from heart disease and lung cancer has been found in a study of over a million individuals. The researchers say their results are relevant to European policymaking relating to air quality. Fine particulate matter (PM2.5) and nitrogen dioxide (NO2) are both air pollutants emitted by vehicles and are found in higher ...

  • Urban greening reduces noise pollution

    Green roofs have the potential to significantly reduce road traffic noise in the urban environment, according to a new study. The results suggest that greening of roofs and walls with materials suitable for growing plants softens the urban environment keeping sound levels low, whereas hard, manmade structures tend to amplify traffic noise. The Environmental Noise Directive (2002/49/EC)1 ...

  • The cost of air pollution impacts on health

    Researchers have developed a new model to assess the health-related external costs arising from air pollution from ten major emission sectors. Applying the model at national and Europe-wide levels, they suggested that the major contributors to costs were industrial power production, agriculture, road traffic and domestic combustion. In recent years, policy action to reduce emissions has targeted ...

  • Reducing noise pollution - success stories

    A project in Ireland has won the European Soundscape Award 2014 for its work on acoustic planning and urban sound design. The prize, presented by the European Environment Agency (EEA) on Thursday evening in Bern, recognises initiatives that can help reduce noise and create healthy soundscapes. Noise pollution can increase stress levels or disturb sleep, affecting human health. Prolonged exposure ...

  • IMMISmt – monitoring system for air pollution and noise in cities

    IMMISmt is a real time monitoring system for air quality and noise. Based on online traffic data, measurements of air quality stations and weather data, IMMISmt calculates traffic induced emissions, background and total pollutant concentrations as well as noise levels within the streets as, e. g., hourly mean values. To do so, IMMISmt combines various models which are validated and widely used in ...

  • Mapping noise pollution simply and cost-effectively

    To manage noise, it must first be assessed. Several commercial noise prediction tools exist, but they are often complex and expensive. A new Irish study evaluates a simpler tool and demonstrates that it produces very similar results to standard commercial software. The European Directive on Environmental Noise1 requires Member States to draw up strategic noise maps and action plans. A noise map ...

  • High levels of air pollution to spread across UK

    As high levels of air pollution are reported across the UK, NPL's role is to make sure that the measurements of pollutant concentrations are as reliable as possible, so that the right warnings can be given and the most appropriate actions taken. The National Physical Laboratory (NPL) manages much of the infrastructure in place to monitor air pollution around the UK, which helps to provide public ...

  • Inauguration of Bangladesh Air Pollution Management Project

    6 Aug 2010 Bangladesh is suffering from some of the world's worst urban air quality problems. Particularly in the non-monsoon period the concentrations of particulate matter regularly exceed proposed standards. The larger cities such as Dhaka and Chittagong have major traffic issues which represent a source of the air quality problems, while industrial sources such as steel mills, cement ...

  • Green infrastructure in street canyons could reduce air pollution

    Planting vegetation in city streets could significantly reduce air pollution in urban street canyons, according to new research. Traffic pollutants are deposited on vegetation at a higher rate than on hard, built surfaces and could reduce the concentration of nitrogen dioxide (NO2) and PM10 in the air by as much as 40% and 60%, respectively, under certain conditions. Outdoor air pollution ...
