Field-portable detection of fentanyl and its analogs: A review

The need to detect fentanyl and its analogs in the field is an important capability to help prevent unintentional exposure or overdose on these substances, which may result in death. Many portable methods historically used in the field by first responders and other field users to detect and identify other chemical substances, such as hazardous materials, have been applied to the detection and identification of these synthetic opioids. This paper describes field portable spectroscopic methods used for the detection and identification of fentanyl and its analogs. The methods described are automated colorimetric tests including lateral flow assays; vibrational spectroscopy (mid-infrared and Raman); gas chromatography–mass spectrometry; ion mobility spectrometry, and high-pressure mass spectrometry. In each case the background and key details of these technologies are outlined, followed by a discussion of the application of the technology in the field. Attention is paid to the analysis of complex mixtures and limits of detection, including the required spectral databases and algorithms used to interrogate these types of samples. There is also an emphasis on providing actionable information to the (likely) non-scientist operators of these instruments in the field.     

Forensic isoscapes based on intra-individual temporal variation of δ18O and 206Pb/207Pb in human teeth

Isotopic signatures used in the georeferencing of human remains are largely fixed by spatially distinct geologic and environmental processes. However, location-dependent temporal changes in these isotope ratios should also be considered when determining an individual’s provenance and/or trajectory. Distributions of the relevant isotopes can be impacted by predictable external factors such as climate change, delocalisation of food and water sources and changes in sources and uses of metals. Using Multi-Collector Inductively-Coupled Plasma Mass Spectrometer (MC-ICP-MS) analyses of ²⁰⁶Pb/²⁰⁷Pb in tooth enamel and dentin from a population of 21 ± 1-year-old individuals born circa 1984 and isotope ratio mass spectrometry (IRMS) of δ¹⁸O in their enamel, we examined the expected influence of some of these factors. The resulting adjustments to the geographic distribution of isotope ratios (isoscapes) found in tooth enamel and dentin may contain additional useful information for forensic identification, but the shifts in values can also impact the uncertainty and usefulness of identifications if they are not taken into account.

KEY POINTS

• Isoscapes of ²⁰⁶Pb/²⁰⁷Pb and δ¹⁸O used for geolocation are not static.
• Within a few years, the enamel and dentin of a person may exhibit measurable differences in ²⁰⁶Pb/²⁰⁷Pb even without changing locations.
• Changes in climatic patterns tied to rising temperatures are more significant than the direct effect of increasing temperature on δ¹⁸O fixed in tooth bioapatite.
• Third molar (M3) enamel mineralisation includes material incorporated from before formal amelogenesis takes place.

Oversight and accountability for serious incidents in Canada: Who polices the police?

This study examines the agencies responsible for investigating when a member of the public is seriously injured, is killed or experiences other serious and potentially criminal actions at the hands of police officers in Canada. The article takes a comprehensive approach by examining all police oversight agencies that are responsible for responding to and investigating allegations of police criminality—eight organizations, across nine jurisdictions. The study integrates insights from public administration and police accountability literature and examines the structures and administration of the agencies. The study provides a critical assessment of the state of police oversight for serious incidents in Canada, it identifies agency outputs (including case substantiation), levels of independence, efforts at transparency, and considers the challenges in attempting to hold police accountable in Canada.
