The temporal and spatial variations of 16 Polycyclic Aromatic Hydrocarbons (PAHs) were examined at multiple sites around Lake Balaton from February 2023 to January 2024. The results indicated that the concentrations of PAHs in sediment were high during the winter months, 448.35 to 619.77 ng/g dry weight, and low during the summer months, 257.21 to 465.49 ng/g dry weight. The concentration of high molecular weight PAHs (HMWPAHs), consisting of 5-6 rings, was greater than that of low molecular weight PAHs (LMWPAHs), which had 2-3 rings. The total incremental lifetime cancer risk (ILCR) for both dermal and ingestion pathways was high for both adults and children during the four seasons, with the highest records as the following: winter > spring > summer > autumn. The ecological effects of the 16 PAHs were negligible except for acenaphthylene (Acy) and fluorene (Fl), which displayed slightly higher concentrations during the autumn and spring, respectively.
研究人员在 2023 年 2 月至 2024 年 1 月期间，在巴拉顿湖周边的多个地点检测了 16 种多环芳烃（PAHs）的时空变化。结果表明，冬季（448.35 至 619.77ng/g 干重）沉积物中 PAHs 的浓度较高，夏季（257.21 至 465.49ng/g 干重）浓度较低。高分子量 PAHs（HMWPAHs，由 5-6 个环组成）的浓度高于低分子量 PAHs（LMWPAHs，由 2-3 个环组成）。对于成人和儿童，四个季节经皮肤和摄入途径的总增量终生癌症风险（ILCR）均较高，记录最高的为：冬季＞春季＞夏季＞秋季。除苊烯（Acy）和芴（Fl）外，16 种 PAHs 的生态效应可忽略不计，这两种物质在秋季和春季的浓度分别略高。
