2. Reaktionen von Phenanthren mit Stickstoffdioxid in ultraviolettem Licht / Reactions of Phenanthrenes with Nitrogendioxid in UV Light

Author

Barlas, H., Parlar, H., Kotzias, D., and Körte, F.

Abstract

The compounds 2-7 were isolated from solutions of phenanthrene (1) and nitrogendi-oxide in carbon tetrachloride after irradiation with UV light having long wavelengths (λ > 290 nm). With the help of spectroscopical methods the proposed structures are derived. Radical mechanisms are proposed for these reactions.

Abstract

Samples of 12 edible fish species from the Marmara Sea were analyzed for organochlorines (PCBs, DDTs, HCB, HCHs, toxaphene, etc.). The results showed that the total concentrations ranged from 329.41 ng/g fat to 1453.87 ng/g fat. DDT group components made up almost half or more of organochlorine contamination. Levels in red mullet were compared with those from neighbor seas. The sum of DDTs as well as HCHs concentrations were markedly lower than in the Black Sea but higher in the Aegean Sea and Mediterranean. Thus, inflow from the Black Sea might be considered as a contamination source for DDT and HCH contamination. On the other hand, total PCB concentration (sum of congeners 28, 52, 101, 118, 138, 153 and 180) detected in this study was comparable or lower than those from the Aegean Sea and Mediterranean. Toxaphene was a minor contaminant. Measured values were below maximum residue levels for human consumption.
