摘要
研究采用13C同位素内标稀释定量法,高分辨气相色谱质谱法(HRGC-HRMS)对珠三角地区造纸行业排水中PC-DD/Fs特征进行了分析。结果表明,该地区造纸行业PCDD/Fs含量为:4.75~80.05 pg/L,且以OCDD占主导地位;同时该类行业PCDD/Fs的TEQ为:0.21~2.02 pg TEQ/L。最后通过对该类行业排水中PCDD/Fs的TEQ年排放量进行讨论,其结果为0.30~12.97 mg TEQ,且年平均排放量(4.42 mgTEQ)只占我国造纸行业TEQ总排放量的很小一部分。
In this study,the PCDD/Fs in drainages of paper industry in the Pearl River Delta region were analyzed by ^13C isotope internal standard method and HRGC-HRMS.The results indicated that the concentration of PCDD/Fs were 4.75-80.05 pg/L and dominated by PCDD as well in the paper industry of this region.Meanwhile,the concentration of TEQ were 0.21-2.02 pg TEQ/L in paper industry.By discussing the annual discharge value of TEQ in this kind of industry,it finally showed that the results were 0.30-12.97 μg TEQ,also the annual mean value(4.42 μgTEQ)was occupied a small fraction of total discharge value of TEQ in paper industry of China.
