Detection and Analysis of Microplastics in Forensic Evidence
Investigating Their Potential Impact on Crime Scene Investigations
The project thesis titled “Detection and Analysis of Microplastics in Forensic Evidence” aims to investigate the presence of microplastics in forensic samples and understand their potential impact on crime scene investigations. Microplastics are small plastic particles (<5mm) that have become a pervasive environmental pollutant, present in various ecosystems including oceans, soil, and air.
Research Objectives:
- To develop a method for the detection and analysis of microplastics in forensic samples.
- To identify sources of microplastic contamination in crime scenes.
- To assess the potential implications of microplastics on the integrity of forensic evidence.
- To explore the use of microplastics as trace evidence in criminal investigations.
Methodology:
The research will involve collecting various types of forensic samples from different crime scenes and analyzing them for the presence of microplastics. Different techniques such as Fourier-transform infrared spectroscopy (FTIR) and Raman spectroscopy will be used for the detection and characterization of microplastics. The study will also include field experiments to simulate crime scene scenarios and assess the transfer of microplastics.
Significance of the Study:
Understanding the presence and potential impact of microplastics in forensic evidence is crucial for ensuring the reliability and accuracy of crime scene investigations. The identification of sources of microplastic contamination can help forensic investigators distinguish between environmental contaminants and true evidence. Moreover, the use of microplastics as trace evidence can provide additional insights into criminal cases.
Expected Outcomes:
- Development of a reliable method for the detection and analysis of microplastics in forensic samples.
- Evidence of the presence of microplastics in various types of forensic samples.
- Insights into the potential impact of microplastics on the interpretation of forensic evidence.
- Potential applications of microplastics as trace evidence in forensic investigations.
In conclusion, the research on the detection and analysis of microplastics in forensic evidence holds significant implications for the field of forensic science. By shedding light on this emerging contaminant, the study aims to improve the accuracy and reliability of crime scene investigations and contribute to the advancement of forensic techniques.
