The occurrence and variability of domoic acid (DA) levels in wild Mytilus galloprovincialis samples, compared with the Pseudo-nitzschia spp. abundance and particulate DA (pDA) concentrations in relation to the environmental changes in the Golden Horn Estuary, Turkey from October 2018 to September 2019. Biotoxin analysis were performed by high-performance liquid chromatography with diode-array detection (HPLC–DAD). DA concentrations in particulate matter (pDA) and mussel samples were found between 0.090–0.685 µg L⁻¹ and 0.905–2.413 µg g⁻¹, respectively. Accumulation of DA in wild mussel samples could be the result of the increasing tendency of P.nitzschia spp. abundances between April and May. Maximum DA levels were detected in particulate matter when the salinity was measured as the lowest in May. Thus, it can be said that the DA production was driven by the significant salinity decrease in the GHE. This is the first attempt regarding the presence of DA in M. galloprovincialis samples collected from Turkish coasts.

与假单胞菌属菌种相比，野生没食性Mytilus galloprovincialis样品中穹mo酸（DA）水平的发生和变异。从2018年10月至2019年9月，土耳其金霍恩河口的丰度和颗粒DA（pDA）浓度与环境变化相关。生物毒素分析是通过高效液相色谱和二极管阵列检测（HPLC-DAD）进行的。颗粒物（pDA）和贻贝样品中的DA浓度分别在0.090–0.685 µg L ^-1和0.905–2.413 µg g ^-1之间。野生贻贝样品中DA的积累可能是P.nitzschia趋势增加的结果spp。四月至五月之间的丰度。当五月份的盐度测得最低时，在颗粒物质中检测到最大的DA水平。因此，可以说，DA的产生是由于GHE盐度的显着下降所致。这是有关从土耳其海岸采集的鸡传染性支原体样品中存在DA的首次尝试。
