To understand the distribution characteristics of nonylphenolics and sterols, samples such as in creek water, sea surface water, waste water treatment plant (WWTP) effluent water, sediment and mussel were collected and analyzed. The principal analytes are nonylphenol (NP), nonylphenol monoethoxylate (NP1EO), nonylphenol diethoxylate (NP2EO), coprostanol (5beta) and cholestanol (5alpha). All these target pollutants showed 100% detection frequency in all of the samples analyzed. Total concentration of nonylphenolic compounds ranged from 334 to 3628ngl(-1) (average: 1331ngl(-1)) in creek water, from 15 to 36400ngl(-1) (average: 1013ngl(-1)) in sea surface water, from 131 to 2811ngg(-1) dry weight (average: 581ngg(-1) dry weight) in sediment and from 50.5 to 289ngg(-1) dry weight (average: 139ngg(-1) dry weight) in mussel. For water samples, levels of nonylphenolics determined in summer season were higher than those in spring season. Among them, nonylphenol and NP1EO was dominant in creek water and seawater, respectively. The highest concentration was recorded in sediment near a WWTP effluent outlet. And high levels of nonylphenolics and sterols were found in about 3km area surrounding WWTP effluent outlet. Coefficient of linear regression (R(2)) for NP in mussel and in sediment was 0.90. Similarly good correlation (R(2)=0.98) was obtained between concentration in water and in mussel indicating that a steady state has been reached in this bay. The calculated bio concentration factor (BCF=2990) for NP in Masan Bay agrees well with reported values in the literature.
为了解壬基酚类化合物和甾醇的分布特征，采集并分析了溪水、海水表层水、污水处理厂（WWTP）出水、沉积物和贻贝等样品。主要分析物为壬基酚（NP）、壬基酚单乙氧基化物（NP1EO）、壬基酚二乙氧基化物（NP2EO）、粪甾醇（5β）和胆甾醇（5α）。在所有分析的样品中，所有这些目标污染物的检出频率均为100%。溪水中壬基酚类化合物的总浓度范围为334至3628ngl(-1)（平均：1331ngl(-1)），海水表层水中为15至36400ngl(-1)（平均：1013ngl(-1)），沉积物中为131至2811ngg(-1)干重（平均：581ngg(-1)干重），贻贝中为50.5至289ngg(-1)干重（平均：139ngg(-1)干重）。对于水样，夏季测定的壬基酚类化合物含量高于春季。其中，壬基酚和NP1EO分别在溪水和海水中占主导地位。污水处理厂出水排放口附近沉积物中的浓度最高。在污水处理厂出水排放口周围约3公里区域内发现了高含量的壬基酚类化合物和甾醇。贻贝和沉积物中NP的线性回归系数（R(2)）为0.90。同样，水中和贻贝中的浓度之间也获得了良好的相关性（R(2)=0.98），表明该海湾已达到稳定状态。马山湾中NP的计算生物富集因子（BCF=2990）与文献报道值吻合良好。
