Stable isotope ratios of marijuana. I. Carbon and nitrogen stable isotopes describe growth conditions.
There remains significant uncertainty in illicit marijuana cultivation. We analyzed the delta(13)C and delta(15)N of 508 domestic samples from known U.S.A. counties, 31 seized from a single location, 5 samples grown in Mexico and Colombia, and 10 northwest border seizures. For a subset, inflorescences and leaves were analyzed separately. These data revealed a strong correspondence, with inflore...
متن کاملLinking mercury, carbon, and nitrogen stable isotopes in Tibetan biota: Implications for using mercury stable isotopes as source tracers
Tibetan Plateau is located at a mountain region isolated from direct anthropogenic sources. Mercury concentrations and stable isotopes of carbon, nitrogen, and mercury were analyzed in sediment and biota for Nam Co and Yamdrok Lake. Biotic mercury concentrations and high food web magnification factors suggested that Tibetan Plateau is no longer a pristine site. The primary source of methylmercu...
متن کاملClimatic and Environmental Reconstruction Based on Stable Isotopes of Parishan Lake (Iran)
The isotopic documents of lake deposition are suitable potential means for studyingthe intercontinental, environmental and climatic conditions. In order to study theenvironmental and climatic conditions of Parishan area in Fars province in Holocene, a Corewas taken with the length of 2m from the Parishan lake sediment. From this core, kernel timeseries was provided from documents of carbon and ...

متن کاملStarvation effects on nitrogen and carbon stable isotopes of animals: an insight from meta-analysis of fasting experiments
Nitrogen and carbon stable isotopic compositions (δ15N and δ13C) of consumers have been used for physiological and food web studies. Previous studies have shown δ15N and δ13C values are affected by several biological and environmental factors during starvation, but the generality of the effect of starvation on δ15N and δ13C values has not yet been tested. Here, we performed a meta-analysis to e...
