1. Methods to measure mass transfer kinetics, partition ratios and atmospheric fluxes of organic chemicals in forest systems
Abstract : Vegetation plays an important role in the partitioning, transport and fate of hydrophobic organic contaminants (HOCs) in the environment. This thesis aimed at addressing two key knowledge gaps in our understanding of how plants exchange HOCs with the atmosphere: (1) To improve our understanding of the uptake of HOCs into, and transfer through, leaves of different plant species which can significantly influence the transport and fate of HOCs in the environment; and (2) To evaluate an experimental approach to measure fluxes of HOCs in the field.

2. How to estimate environmental persistence : Understanding persistence of organic micropollutants in rivers from a multidisciplinary perspective
Abstract : Organic micropollutants such as food additives, pharmaceuticals and personal care products are found in rivers worldwide. Persistence is a key criteria in chemical risk assessment as micropollutants that are persistent pose an exposure hazard to humans and the environment. READ MORE

3. Chemical Pollutants Released to the Marine Environment by Degradation of Plastic Debris
Abstract : Since the beginning of the mass production in the 1940s, plastic has been manufactured in quickly increasing amounts. Plastic debris accumulates in the environment and lately much attention has been drawn to the pollution in the world’s oceans. READ MORE

4. Forecasting chemical exposure in a changing world
Abstract : Exposure to anthropogenic chemicals in natural and built environments is a threat to humans and other species. Now and through the 21st Century, the world will experience a large number of global changes, including anthropogenic climate change, shifts in demographics, agricultural expansion, socioeconomic development, and an increasing number and volume of chemicals on the market.
