摘要

双酚 A（BPA）是一种内分泌干扰物，广泛存在于海洋环境中，可在海洋生物体内蓄积，即使浓度很低，也会对人类健康构成严重威胁。本研究提出了一种检测食用贻贝中双酚 A 的新方法，与现有方法相比，该方法具有多项优势。它成本更低、速度更快、不受生物材料数量的影响，甚至可用于分析非常小的样本：双酚 A 的检测是通过一种量身定制的方法进行的，该方法能够在不同的浓度和时间点发现活体贻贝中添加或生物累积的污染物。在环境条件下，不可食用的贻贝（未去皮）的生物蓄积量可达 0.6 μg g-1（d.w.）。我们的方法被应用于体内实验，结果发现在贻贝组织中检测到的双酚 A 浓度取决于给药量。这种方法可为今后的研究提供基线，并改进环境监管和风险评估规程。

Evaluation of potential bioaccumulation of Bisphenol A in the mussel Mytilus galloprovincialis

Bisphenol A (BPA) is an endocrine disruptor, widespread into the marine environment, which can be accumulated in marine organisms, representing a serious threat to human health, even if it is present at low concentrations.

This study presents a new methodology for detecting BPA in the edible mussel Mytilus galloprovincialis which, compared to the existing ones, has several advantages. It is cheaper, faster, independent of the amount of organism material considered, and can be used even for the analysis of very small samples: LOD of 0.13 μg g⁻¹ was obtained extracting 50 mg of tissue.

The detection of BPA was obtained by means of a tailored method able to spot the contaminant spiked or bioaccumulated by living mussels at different concentrations and time points. Under environmental conditions inedible mussels (not depurated) bioaccumulated up to 0.6 μg g⁻¹ (d.w.).

Our methodology was applied to in vivo experiments whereas the concentration of BPA detected in mussels’ tissues was found to depend on the quantity administered. This methodology may provide the baseline for future research and improve environmental regulation and risk assessment protocols.
