Sediment and water samples collected from 32 locations in Ulsan Bay and adjacent inland areas were analyzed for polycyclic aromatic hydrocabons (PAHs), nonylphenol (NP), octylphenol (OP), bisphenol A (BPA), organochlorine (OC) pesticides (HCB, HCHs, CHLs, and DDTs), and polychlorinated biphenyls (PCBs) to characterize their spatial distribution and contamination status. PAHs were detected in nearly all sediment and water extracts from Ulsan Bay and its inland locations. The sedimentary PAH concentrations ranged from 17 to 3,100 ng/g on a dry weight basis (DW), which were predominated by two- and three-ring aromatic hydrocarbons in river and/or stream, and four- to six-ring compounds in Ulsan Bay sediment. Concentrations of PAHs in pore water samples were generally two or three orders magnitude less than those of corresponding sediment samples. Maximum concentrations of NP, OP, and BPA in sediments were 1,040, 120, and 54 ng/g DW, respectively. Concentrations of OP and BPA were, on average, 5- to 13-fold less than those of NP. PCB concentrations in sediment ranged from 1.4 to 77 ng/g DW, which were predominated by lower chlorinated congeners such as di- through pentachlorinated biphenyls. Among different OC pesticides analyzed, concentrations of DDTs were the greatest, ranging from 0.02 to 41.9 ng/g DW. NP concentrations were greater at inner locations proximal to municipal wastewater discharges into rivers and/or streams, whereas the concentrations of PCBs and PAHs were great near the sites of high industrial activities. Sediment-pore water partitioning coefficients correlated with those of reported Koc or Kow values for selected PAHs in Ulsan Bay, but these varied by an order of magnitude for stream and/or river sediments.
从蔚山湾及其邻近内陆地区的32个地点采集了沉积物和水样，分析其中的多环芳烃（PAHs）、壬基酚（NP）、辛基酚（OP）、双酚A（BPA）、有机氯（OC）农药（六氯苯、六氯环己烷、氯丹和滴滴涕）以及多氯联苯（PCBs），以表征它们的空间分布和污染状况。几乎在蔚山湾及其内陆地区的所有沉积物和水提取物中都检测到了PAHs。沉积物中PAHs的浓度以干重计为17至3100 ng/g，河流和/或溪流中的PAHs以二环和三环芳烃为主，而蔚山湾沉积物中则以四环至六环化合物为主。孔隙水样中PAHs的浓度通常比相应沉积物样品低两到三个数量级。沉积物中NP、OP和BPA的最大浓度分别为1040、120和54 ng/g干重。OP和BPA的浓度平均比NP低5至13倍。沉积物中PCBs的浓度为1.4至77 ng/g干重，以二至五氯联苯等低氯代同系物为主。在所分析的不同OC农药中，滴滴涕的浓度最高，为0.02至41.9 ng/g干重。靠近城市废水排入河流和/或溪流的内陆地区NP浓度较高，而PCBs和PAHs的浓度在高工业活动地点附近较高。沉积物-孔隙水分配系数与蔚山湾选定PAHs报道的Koc或Kow值相关，但河流和/或溪流沉积物的这些系数相差一个数量级。
