This research aimed to assess the potential of emerging contaminants as environmental quality indicators for short-term monitoring programs, in contrast with traditional contaminants. Thirteen sediment samples from from Piratininga, a coastal lagoon subjected to anthropogenic impact, were analyzed for the following compounds: napropamide, diclofenac, naproxen, triclosan, ibuprofen, 17β-estradiol, bisphenol A, nadolol, ethofibrate and carbamazepine. The developed method, which included solid phase extraction, derivatization, and analysis by gas chromatography–mass spectrometry, demonstrated robustness and suitability with quantification limits between 0.32 and 1.49 ng g−1. The concentrations of etofibrate, nadolol, napropamide and diclofenac were below the quantification limits for all the analyzed samples. The highest concentration was reported for bisphenol A (4.76 ± 0.44 ng g−1), followed by 17β-estradiol (2.88 ± 0.65 ng g−1), ibuprofen (2.70 ± 1.67 ng g−1) and triclosan (1.5 ± 0.43 ng g−1). The detected concentrations, spatial distribution, and local climatic conditions with distinct dry and wet seasons indicate the feasibility of biannual environmental quality monitoring. By evaluating the concentrations and statistical treatment, the use of contaminants of emerging concern as short-term indicators proved promising, leading to an optimized monitoring program from nine to three compounds (bisphenol A, ibuprofen and triclosan) and a sampling grid reduced from 13 to 4 points.

新兴污染物作为富营养化沿海泻湖短期环境变化的指标


与传统污染物相比，本研究旨在评估新兴污染物作为短期监测计划的环境质量指标的潜力。分析了来自遭受人为影响的沿海泻湖 Piratininga 的 13 个沉积物样品中的以下化合物：萘罗普胺、双氯芬酸、萘普生、三氯生、布洛芬、17β-雌二醇、双酚 A、纳多洛尔、乙氧贝特和卡马西平。开发的方法包括固相萃取、衍生化和气相色谱-质谱分析，在定量限为 0.32 至 1.49 ng g-1 时表现出稳定性和适用性。依托贝特、纳多洛尔、萘丙胺和双氯芬酸的浓度均低于所有分析样品的定量限。据报道，双酚 A （4.76 ± 0.44 ng g-1） 的浓度最高，其次是 17β-雌二醇 （2.88 ± 0.65 ng g-1）、布洛芬 （2.70 ± 1.67 ng g-1） 和三氯生 （1.5 ± 0.43 ng g-1）。检测到的浓度、空间分布和具有不同旱湿季节的当地气候条件表明一年两次环境质量监测的可行性。通过评估浓度和统计处理，使用新出现的污染物作为短期指标证明是有希望的，从而从九种化合物（双酚 A、布洛芬和三氯生）优化了监测程序，并将采样网格从 13 点减少到 4 点。
