Unit | Environmental Exposures and Health

Measurement of Mobile Phone Radiation and Concentration

Our continuous interaction with the environment affects our health in both positive and negative ways. Researchers in the Environmental Exposures and Health unit develop and integrate novel tools and methods to investigate the health effects of a wide range of environmental exposures. These include transportation noise, ionizing and non-ionizing radiation, ambient and indoor air pollution, environmental tobacco exposure, pesticides and climate change including heat waves.

From Exposure Assessment to Effective Public Health

The unit conducts epidemiological studies in children, adolescents and adults. Current studies are dealing with health-related quality of life, behaviour, respiratory diseases, childhood tumours, cardiovascular diseases and neurodegenerative diseases. The unit also conducts health risk assessments, including meta-analyses and systematic reviews and contributes to the development of guidelines and regulatory limits in the field of environmental health.

The EPOCHAL Study

Almost 20% of the Swiss population suffer from a pollen allergy, a dramatic increase from 100 years ago when it was less than 1%. At the same time, the amount of pollen in the air has increased. There is more to pollen allergies than bothersome sneezing: The EPOCHAL study will investigate how different concentrations of pollen from trees, grasses and weeds affect the heart, lungs, brain, sleep and quality of life. We aim to understand these health effects in both pollen-allergic and non-allergic people. Read more and find out how to participate in the EPOCHAL study here.

 

 

PoCHAS: Pollen and Cardiorespiratory Health and Allergic Symptoms

The PoCHAS project aims to model the ambient exposure to airborne pollen retrospectively using spatiotemporal models. This allows us to investigate how short-term exposure to pollen is related to respiratory and cardiovascular events. We will study mortality and hospitalization. Moreover, in light of increasing allergy prevalence and changing pollen season, we aim to study how the relationship between pollen and health has developed in the last decades, and which subpopulations might be most at risk. Moreover, combined exposure to pollen, air pollution and weather conditions may have synergistic effects, which alter the allergenicity of pollen - a research area which has been hardly explored.

MOBI-AIR: Accounting for MOBility in AIR pollution exposure estimates in studies on long-term health effects

Large scale epidemiological studies investigating long-term health effects of air pollution can typically only consider the residential locations of the participants, thereby ignoring the space-time activity patterns that likely influence total exposure. People are mobile and can be exposed to considerably different levels of air pollution or air pollution mixtures when inside vs. outside, commuting, recreating, or working. Neglecting these mechanisms in exposure assessment may lead to incorrect distributions of exposure over the population which may lead to incorrect exposure health relations in epidemiological studies. The main aim of this study is to assess whether more sophisticated estimates of individual exposure, considering population mobility, decreases the bias in health studies. Further information

Evaluation of Heat Wave Related Mortality and Adaption Measures in Switzerland

Heat is a stressor for the body and it is well proven that heat causes excess mortality. The aim of this project is to obtain a better understanding how heat waves affect mortality and morbidity in Switzerland. In addition, a tool box is derived on potential adaption measures that can be taken by various stakeholders to prevent heat related health effects. The effectiveness of these adaption measures are evaluated in the course of the project. Read more

Joint South Africa & Swiss Chair in Global Environmental Health

This chair in Cape Town university addresses emerging environmental health problems in South Africa. The collaboration consists of four projects: (i) a cohort study on agricultural pesticides effects on the development and respiratory health effects among rural children; (ii) a cohort study on the effects of ambient air pollutants on childhood asthma; (iii) an ecosystem approach on the health risks associated with chemical pollution and bio contamination of water sources and soils; and (iv) a health risk assessment on the impact of climate change on ecosystems, water and chemical usages.

TraNQuIL2 - Toward Prevention of Health Effects from Acute and Chronic Noise Exposure

Epidemiological research in the last decade has revealed associations between various cardiometabolic diseases and road, railway and aircraft noise. However, still little is known about mental health effects and most effective interventions to reduce health burden from transportation noise exposure. The TraNQuIL2 study will address several important research questions in relation to acute and long-term health effects from transportation noise to enhance our understanding of effective individual and population-level prevention measures.
