FORENSIC PALYNOLOGY PDF

Pollen can reveal where a person or object has been, because regions of the world, countries, and even different parts of a garden will have a distinctive pollen assemblage. The clothes may contain pollen that was released after death the time of death can be determined by forensic entomology. If it is found to be from a place other than where the body was found, this indicates that the body was moved after death. Palynology[ edit ] Palynology is the study of pollen, spores, and other microscopic plant bodies such as dinoflagellates marine algal cysts.

His jacket has the tell-tale orange stains of lily pollen. You have found the culprit. While you may not be a professional, you just utilized forensic palynology to solve your case. Forensic palynology refers to the use of pollen and spore identification and analysis to investigate civil or criminal cases. Pollen and spores are the tiny, powder-like reproductive units of plants. Pollen is utilized in sexual reproduction. Both are produced in large quantities, are relatively resistant to destruction and have unique appearances that allow different species to be identified with a microscope.

Several difference species of pollen viewed with scanning electron microscope. Collecting evidence from a crime scene. The following examples are all true cases that were solved with the help of forensic palynology.

The Missing Body in Vienna, Austria, The earliest documented case of police using pollen to solve a crime occurred in Austria in A man disappeared during a trip down the Danube River. Even though his body could not be found, he was presumed murdered. A sample of the mud was sent to palynologist Wilhelm Klaus of the University of Vienna for analysis. Klaus discovered that the mud contained spruce, willow and alder pollen as well as a million-year-old hickory pollen grain from an exposed Miocene-aged deposit.

There was only one small area along the Danube River that contained this exact combination of pollen. Investigators told the suspect that not only did they know that he killed the man, they knew exactly where he did it.

The defendant was so shocked that he confessed to the crime and led authorities to grave which, incidentally, was within the region identified by Professor Kraus.

A memorial for the victims of the Srebrencia Massacre. The Bosnian authorities attempted to cover up the genocide. They exhumed the mass graves and re-buried the victims in smaller graves, claiming that they were casualties of separate, smaller battles. Professor Tony Brown of the University of Exeter was part of a team of forensic analysts whose job was to link the many secondary burial sites to a few primary ones. Soil samples were taken from the skeletons, the graves and from around the burial sites.

Pollen and spores from the soil were isolated, cleaned and analyzed. The examination provided evidence that the bodies had been moved. For example, one of the primary burial sites was a wheat field. Remains found in secondary sites were linked to the original mass grave through the presence of distinctive grains of wheat pollen.

According to the report by Murray George Pop of Germany might be the first scientist who examined soil evidence and led the solution of the murder case in Microscopically, soil is heterogenous mixture consist of organic matter, rock fragments, mineral grains, clay, oxides etc. Therefore unique particles can be of important to characterize soil evidence.
