Sourcing Brazilian marijuana by applying IRMS analysis to seized samples.
The stable carbon and nitrogen isotopic ratios were measured in marijuana samples (Cannabis sativa L.) seized by the law enforcement officers in the three Brazilian production sites: Pernambuco and Bahia (the country's Northeast known as Marijuana Polygon), Pará (North or Amazon region) and Mato Grosso do Sul (Midwest). These regions are regarded as different with respect to climate and water a...

متن کاملCarbon and nitrogen stable isotopes as indicative of geographical origin of marijuana samples seized in the city of São Paulo (Brazil).
The drug trafficking is one of the most serious problems related to the Public Safety in Brazil, especially in the most populous areas of the country, as is the case of the city of São Paulo. In this work, it was developed a methodology that can help tracking the traffic routes of marijuana samples seized in the city of São Paulo, based on stable carbon and nitrogen isotopes, which are related ...
متن کاملStable isotope ratios as a tool in microbial forensics--Part 2. Isotopic variation among different growth media as a tool for sourcing origins of bacterial cells or spores.
Since the anthrax attacks of 2001 the need for methods to trace the origins of microbial agents has become urgent. The stable isotope ratios of bacteria record information from both the nutrients and the water used to make their culture media and could potentially be used to provide information about their growth environment. We present a survey of carbon (C), nitrogen (N), and hydrogen (H) sta...
