1. Methods to measure mass transfer kinetics, partition ratios and atmospheric fluxes of organic chemicals in forest systems
Sammanfattning : 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
Sammanfattning : 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. LÄS MER
Sammanfattning : 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. LÄS MER
Sammanfattning : Both chemical-specific (e.g. physical-chemical properties) and environmental (e.g. LÄS MER
5. Occurrence and fate of emerging and legacy flame retardants : from indoor environments to remote areas
Sammanfattning : Persistent organic pollutants (POPs) are toxic chemicals that can be found in various matrices in all corners of the planet, including remote areas such as the Arctic. Several POPs are known and monitored but given the abundance of new chemicals in commerce about which little is known, chemicals that may be new POPs are constantly being screened for. LÄS MER
