Forensic palynology is the study of pollen and powdered minerals, their identification, and where and when they occur, to ascertain that a body or other object was in a certain place at a certain time. Pollen can tell a lot about where a person or object has been, because regions of the world, or even more particular locations such a certain set of bushes, will have a distinctive collection of pollen species. Pollen evidence can also reveal the season in which a particular object picked up the pollen. Pollen has been used to trace activity at mass graves in Bosnia, catch a burglar who brushed against a ''Hypericum'' bush during a crime, and has even been proposed as an additive for bullets to enable tracking them.〔''Newscripts'', Chemical & Engineering News, 86, 33, 18 August 2008, p. 88〕 For instance, a dead body may be found in a wood, and the clothes may contain pollen that was released after death (the time of death can be determined by forensic entomology), but in a place other than where it was found. That indicates that the body was moved. ==Palynology== Palynology is the study of pollen, spores and other microscopic plant bodies such as dinoflagellates (marine algal cysts). Pollen carries the male gametes (sex cells) of flowering plants and plants that produce cones (e.g. pine trees). Spores are asexual reproductive bodies of ferns, mosses and fungi. 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: by botanists for plant taxonomy and phylogeny; by immunologist to investigate allergenic pollen; by archaeologists to study the customs, rituals and agricultural practices of ancient peoples; by zoologists and environmental scientists to understand foraging habits of insects, birds and mammals and to investigate past native vegetation and habitats in order to preserve the present and protect endangered species. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Forensic palynology」の詳細全文を読む スポンサード リンク
