Forensic palynology is the examination and comparison of pollen, spores and other microscopic particles. It can assist in any crime where there is a requirement to establish whether or not a person or vehicle may have been in a particular location.
Palynology is often used in association with other evidence types. For example, it might be useful to carry out a comparison of soil on an exhibit with soil from a scene of crime and to also carry out a comparison of the pollen from both locations. A botanical survey of the location may also assist with the interpretation.
