  2. 21. Assessing environmental exposures. Air pollution in Scania, southern Sweden

    Author : Ralf Rittner; Avdelningen för arbets- och miljömedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; air pollution; dispersion modelling; health impact assessment; emission database; Particulate matter PM ; epidemiology;

    Abstract : Background: The environment where we humans live provides the fundamental requirements we need to survive – food to eat, water to drink, and air to breathe. The quality of these elements has a major impact on human health, as they can contain substances that are detrimental to health. These we call environmental pollutants. READ MORE

  4. 22. An evaluation of sources contributing to urban runoff pollution

    Author : Alexandra Müller; Maria Viklander; Helene Österlund; Jiri Marsalek; Shirley E. Clark; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stormwater quality; Pollution sources; Building surface materials; Traffic activities; Source identification methods; VA-teknik; Urban Water Engineering; Centrumbildning - Centrum för dagvattenhantering DRIZZLE ; Centre - Centre for Stormwater Management DRIZZLE ;

    Abstract : Urban runoff is a significant pathway for the transport of diverse substances from the urban environment to receiving water bodies. Many of these substances are pollutants of environmental concern with potentially harmful effects on aquatic life. READ MORE

  5. 23. Air Pollution from Ships - Emission Measurements and Impact Assessments

    Author : Hulda Winnes; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fuel; air pollution; ships; impact assessment; emission measurement; ship emissions; emission inventory; manoeuvring ships; abatement;

    Abstract : Environmental impact and air pollution from ships have received increasing attention the last decades. Due to combustion characteristics of typical marine engines and a wide spread use of unrefined fuel, the global fleet emits significant amounts of SO2, NOX and particles to air. READ MORE

  6. 24. Mathematical Modelling in Catalytic Automotive Pollution Control

    Author : Lennart Andersson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; automotive pollution control; matematical modelling; monolith; selective catalytic reduction; mass transfer;

    Abstract : Design and control of honeycomb monolith reactors for catalytic automotive pollution control by mathematical modelling of the reactor has been studied. One aspect of the design has been that the use of metallic monolithic catalysts for automotive emission control raises certain optimization possibilities. READ MORE

  7. 25. Heavy Metal Exposure in Early Life - Health and Labour Market Perspectives

    Author : Yana Pryymachenko; Centrum för ekonomisk demografi; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Metal pollution; accumulated exposure; lead pollution; GPA; education; earnings; infant mortality; cognitive skills;

    Abstract : This thesis consists of three empirical studies on the effects of exposure to heavy metal pollution in early childhood on a broad set of individual outcomes. The first study analyses how accumulated exposure to metal pollution during childhood affects long-run outcomes. READ MORE
