title: [Determination of B(a)p contents of pine tar and its extractives].
abstract: In this paper, the B(a)P contents of pine tar and its extractives A, B were determined by PC-Scanning method. After combining extraction by caffeine and formic acid with PC-Scanning method, the B(a)P contents were obtained. The results showed the B(a)P contents of pine tar and its extractives A, B were 6171.3 ppb, 2285.2 ppb, 129.6 ppb, among them, the B(a)P content of B was the lowest.
