This study was derived from field investigations to assess bisphenol A (BPA) concentrations in the sea and river sediments of the Gulf of Gdansk. Black carbon (BC) and total organic carbon (TOC) were identified as influencing factors on the accumulation. As a result of the transportation of BC with organic matter via rivers into the Gulf of Gdansk, the highest mean concentrations (11.26ngBPA/(gdryweight (dw))), were determined in the sediments of river estuaries. Sediments in coastal stations were characterized by the lowest mean concentrations (5.73ngBPA/(gdw)). TOC content below 0.1% determined the sorption of BPA on BC particles in sediments, and statistically significant correlation between the concentration of BPA and the BC/TOC ratio was found in these cases. In addition, dependency between the concentration of BPA and the content of BC was discovered in sediments where the BC/TOC ratio was >0.33.
本研究源于实地调查，旨在评估格但斯克湾海域和河流沉积物中双酚A（BPA）的浓度。黑碳（BC）和总有机碳（TOC）被确定为影响其积累的因素。由于BC通过河流与有机物一起输送到格但斯克湾，河口沉积物中的平均浓度最高（11.26ngBPA/（g干重（dw）））。沿海站点沉积物的平均浓度最低（5.73ngBPA/（gdw））。TOC含量低于0.1%决定了沉积物中BPA在BC颗粒上的吸附，在这些情况下发现BPA浓度与BC/TOC比值之间存在统计学上的显著相关性。此外，在BC/TOC比值>0.33的沉积物中发现了BPA浓度与BC含量之间的相关性。
