The Effects Of Heavy Metal Contamination In Soil On Dna Degradation After Decomposition, Samantha Hofland
The Effects Of Heavy Metal Contamination In Soil On Dna Degradation After Decomposition, Samantha Hofland
Graduate Student Theses, Dissertations, & Professional Papers
The application of DNA is an ever-expanding field of research with many implications in the field of forensic investigation. Research into DNA obtained from soil is ongoing and suggests a new avenue in forensic investigation. This research seeks to understand the effects of heavy metal on the preservation of DNA within soil after decomposition of remains. Using pigs as a proxy for human remains, the effects of heavy metal contamination on the microbial environment and endogenous pig DNA was observed. This gave broad insight into the effect of surface burial and Western Montana; summer climate has on DNA degradation.

Dna Analysis On Ceramic Cooking Vessels, Britney J. Radford

Ceramic vessels are a durable material found in abundance throughout the archaeological record. Organic residue analysis has been used to study ceramic vessels utilizing lipid analysis and protein analysis. Lipids and proteins analysis provide limited information at the genus level, leaving out valuable information that species-specific results can tell us such as unique genetic and environmental information. Lipids and proteins analysis provide limited information at the genus and taxonomic levels leading to issues of misclassification of species. If only certain animals or plants of a genus are being used, then unique genetic and environmental information found only at the species …

DNA is a valuable resource as a unique identifier of physical characteristics at both the population and individual levels. Due to a variety of factors that contribute to genetic decay, forensic and bioarchaeological investigators have limited outlets in which to extract viable DNA after most of a body’s organic materials have fully decomposed. This preliminary research focused on extracting DNA from the soil surrounding buried Sus scrofa domesticus cadavers to confirm the presence of viable and analyzable DNA. After a decomposition period of five months in Montana, soils were collected at incremental distances above the remains and sequenced to identify …
