Stable isotopes of carbon, nitrogen and hydrogen in the contemporary north American human food web
The use of stable carbon, nitrogen and hydrogen isotopes as dietary markers was investigated in ten healthy subjects living in metropolitan Chicago, USA. Forty foods were isotopically analyzed and compared with human plasma and hair. From isotopic analysis and average U.S. food intake data, the isotopic composition of dietary protein was estimated to be δ13CPDB = ‐18.0‰, δ13NAIR = 5.2‰, and δ2HSMOW = ‐69‰. Dietary lipid was estimated to be δ13C =…
On the Origin of Carbonaceous Particles in American Cities
During the past three years radiocarbon assay has emerged as a primary tool in the quantitative assignment of sources of urban and rural particulate pollution. Its use in several major field studies has come about because of its excellent (fossil/biogenic) discriminating power, because of advances in 14 C measurements of small samples, and because of the increased significance of carbonaceous particles in the atmosphere. The problem is especially…
