Chemical footprinting approaches quantify and evaluate the potential human and ecotoxicological impact of a product due to its constituting chemicals. Quantifying the chemical footprint of consumer products released mostly in wastewater after their use, requires a thorough understanding of the emission, fate, and effects of their constituting chemicals and the parameters influencing the variability and uncertainty of each step. The main aim of this thesis was to improve the reliability of key factors that determine the chemical footprint of consumer products. For this sake, a new method was developed to estimate chemical load emissions from consumer survey data. Further, mixed-effects models were applied to improve predictions of chemical emissions from activated sludge wastewater treatment plants as well as from plastic packaging into food. Finally, a method to improve the reliability of chemical effect assessment was developed by combining two types of in silico methods.
By September we will present an overview of SENSE dissertations on this page, with links to the full texts of the dissertations.
