【摘要】：曹妃甸和黃驊港是河北省近海工業(yè)布局和港口分布較密集的區(qū)域,對(duì)其近岸海域海水水質(zhì)進(jìn)行監(jiān)測(cè)具有重要意義。2014年9月采集研究區(qū)近岸海域表層海水,并利用GC-MS對(duì)其中16種優(yōu)先控制PAHs進(jìn)行測(cè)定。結(jié)果表明,曹妃甸和黃驊港近岸海域表層海水中∑PAHs含量分別為52.6~192.1 ng·L~(-1)和85.4~156 ng·L~(-1),平均含量分別為74.59 ng·L~(-1)和121.45 ng·L~(-1)。黃驊港近岸海域∑PAHs含量高于曹妃甸近岸海域的含量,但PAHs的種類沒有差異。對(duì)比其他研究區(qū)域水體中PAHs的含量,本區(qū)域表層海水中PAHs的含量處于中等水平,屬于輕污染。異構(gòu)體比值結(jié)合該區(qū)域現(xiàn)狀分析初步判斷,研究區(qū)表層海水中PAHs來(lái)源于石油污染和煤、生物質(zhì)等的燃燒。應(yīng)用風(fēng)險(xiǎn)商值法(RQ)對(duì)研究區(qū)域表層海水中PAHs的生態(tài)風(fēng)險(xiǎn)進(jìn)行評(píng)價(jià),結(jié)果表明該海域存在低生態(tài)風(fēng)險(xiǎn),需采取措施控制PAHs的污染。
[Abstract]:Caofeidian and Huanghua Port are the areas with dense industrial distribution and port distribution in the offshore area of Hebei Province, and it is of great significance to monitor the seawater quality in the inshore sea area of Caofeidian and Huanghua Port. GC-MS was used to determine 16 priority controlled PAHs. The results show that the 鈭，
