The palynologist will study, analyse and compare pollen grains using their own expertise but also pollen reference collections if available. All of these features make them especially ideal for use in a forensic investigation.

forensuc Pollen recovered from a suspect that happens to match that of a crime scene may simply suggest that the individual had visited that area at some point recently, not necessarily prove that they have committed a crime. Unfortunately without a body, and of course the suspect proclaiming his innocence, there was not much of a case against this man.

A person can easily inadvertently pick up pollen from a crime scene, whether it be in mud on their shoes or on their clothes from directly brushing against a plant in the area.

Forensic Palynology

This may particularly be suspected if the body carries large amounts of a particular pollen that is not found at the location in which the body was found. If a suspect was present at a particular crime scene at which pollen can be found for instance a field or gardenthey may have picked up pollen on their clothing or in their hair. Spores are asexual reproductive bodies of ferns, mosses and fungi.

That indicates that the body was moved. Forensic palynology relates to the application of the study of pollen and spores to legal matters, often used to establish links between objects, people and places based on the analysis and identification of pollen.

Pollen and spores provide clues as to the source of the items and the characteristics of the environments from which the material on them is sourced. Whilst on a trip down the Danube River, an Austrian man disappeared. Because of the dispersal mechanisms of some plants, pollen can be readily picked up and transferred.


Only a small forensiic north of Vienna was consistent with this combination of types of fordnsic. Why do it and how it works. Pollen and spore assemblages characterise different environments and scenes and can easily be picked up and transported away from scenes of interest without providing any visual clue to a suspect as to what has occurred.

Forensic palynology: why do it and how it works.

Archived from the original on 3 February Forensic Palynology Forensic palynology relates to the application of the study of pollen and spores to legal matters, often used to establish links forehsic objects, people and places based on the analysis and identification of pollen.

In addition to this, scanning electron microscopy SEM may be utilised. For instance, palgnology may be possible to link a suspect to an object, a vehicle to a crime scene, or even link two separate incident scenes.

Although this application of palynology may not necessarily be able to establish an exact location, it may be least be possible to rule out certain geographical locations and point the investigation in the right direction. Forensic palynology has been a law enforcement tool for over 50 years.

For instance, a body that is believed to have been moved may carry pollen grains that can be analysed and traced to a likely location. Paalynology evidential samples will be collected such as from objects or peoplebut in addition to this control samples will be collected.

Finally, autogamous plants are self-pollinating, so the pollen they produce does not need to travel. Review of Paleobotany and Forehsic Klaus was able to identify a number of modern pollens in the mud, including spruce, willow and alder pollen, along with a significantly older fossil forejsic.

Because pollen is so resilient, it can often stick to other objects even after that object has been washed. An example of forensic palynology”, Forensic Science International3: However it must be considered that although the presence of pollen may establish a link, the lack of pollen does not necessarily prove that there is not a link.

Furthermore, with the development of multi-disciplinary approaches to environmental analyses of crime scenes, far more detailed information is now available to law enforcement agencies, enabling them to determine with greater accuracy what may have happened during the commission of criminal activities. Part of a series on. Pollen carries the male gametes sex cells of flowering plants and plants that produce cones e. Palynology Forensic disciplines Forensic palynology.


Palynology is used by geologists to help date rocks for petroleum, mining and water exploration and to help unravel the history of plants on Earth; by geographers to investigate climatic and environmental change: The defendant was confronted with this new piece of information, at which point he finally cracked and confessed to the murder.

The study of pollen can also be used to determine the travel history of an item. A fprensic and business partner of the victim soon fell under suspicion, and was arrested and charged with murder. Retrieved from ” https: Social Psychiatry Psychology Psychotherapy Social work.

Pollen and Spores Pollen refers to a powder containing the male gametophytes of seed-producing plants, produced and dispersed in order foremsic pollinate and reproduce. Spores, on the other hand, are units of asexual reproduction. In some cases it may be necessary to ascertain where an item has originated from, especially illicit drugs, money, antiques and even food. This page was last edited on 22 Januaryat Case Study The first documented use of the analysis of pollen and spores to a forensic investigation was in Austria in Forensic Applications Palynological samples can be recovered from a wide range of sources, including people, such as on their clothes, in their hair or even in their nasal passage, vehicle tyres, air filters in cars, on objects and in mud.

Similarly, palynology may be able to determine the location of a crime scene if it is not known. Pollen grains typically have a fairly hard coat to protect them as they pass from one plant to another, making them relatively resilient to destruction.
