Pang, M. (author), Jin, J. (author), Segers, A.J. (author), Huiya, J. (author), Fang, L. (author), Lin, H.X. (author), Liao, H. (author)Super dust storms re-occurred over East Asia in 2021 spring and casted great health damages and property losses. It is essential to achieve an accurate dust forecast to reduce the damage for early warning. The forecasting system fundamentally relies on a numerical model which can forecast the full evolution of dust storms. However, large...article 2023

(author)Background Pesticides can be transported from the site of application to homes via different routes and lead to exposure of residents, raising concerns regarding health effects. We built a deterministic model framework (OBOmod) to assess exposure of residents living near fields where pesticides are applied. Methods OBOmod connects five...article 2022

(author)When calibrating simulations of dust clouds, both the intensity and the position are important. Intensity er rors arise mainly from uncertain emission and sedimenta tion strengths, while position errors are attributed either to imperfect emission timing or to uncertainties in the trans port. Though many studies have been conducted on the cal...article 2021

Jin, J. (author), Lin, H.X. (author), Heemink, A. (author), Segers, A. (author)In previous studies, a number of model-based dust forecasts and early warning systems have been developed for the prevention of environmental impacts due to dusts. However, the accuracy of the model is limited by imperfect identification of dust emissions, in particular by the friction velocity threshold parameterization in the emission process....article 2018

den Uil, H. (author), Wittkampf, S.A. (author)ECN has developed a simple and inexpensive method to prevent clogging of dust in capillary columns of mass spectrometers or gas chromatographs. In some processes there are dust particles present in the process gas. The method developed by ECN is a smart solution that helps to prevent that dust particles end up in the analyzer.other 2016
