Research project identifies deficiencies in models used for assessing chemical safety at workplaces

A research project affiliated with the University of Helsinki's Institute for Atmospheric and Earth System Research has identified serious deficiencies in the Stoffenmanager and Advanced REACH Tool occupational exposure models used for assessing chemical safety and calls for the discontinuation of their use in statutory chemical safety assessment.

Mobility restrictions can have unexpected impacts on air quality

 E-Mail An international collaborative study led by University of Helsinki has conducted a holistic study to investigate the effects of COVID-19 restrictions on several air quality pollutants for the Po Valley region in northern Italy. The area is well known to have one of the worst air quality standards in Europe and is highly influenced by anthropogenic (human-led) activities. The study was done between research groups in Finland, Italy and Switzerland and the results were published in the journal Environmental Science: Atmospheres. Scientists have combined air quality measurements and computer simulation data over several locations in the region. The resulting studies show that reduced emissions from traffic lead to a strong reduction of nitrogen oxides, while have had limited impact on aerosol concentrations, contributing to a better understanding of how the air pollution is formed in the Po Valley.
