Environmental pollution poses a significant and pressing threat to the overall well-being of aquatic ecosystems in modern society. This study showed that pollutants like dusts from AC filter, fan wings and Traffic dust PM 2.5 were exposed to Artemia salina in pristine form and in combination. The findings indicated that exposure to multi-pollutants had a detrimental effect on the hatching rates of A. salina cysts. Compared to untreated A. salina, the morphology of adult (7th day old) A. salina changed noticeably after each incubation period (24-120 h). Oxidative stress increased considerably as the exposure duration increased from 24 to 120 h compared to the control group. There was a time-dependent decline in antioxidant enzyme activity and total protein concentration. When all particles were used all together, the total protein content in A. salina decreased significantly. All particles showed a considerable decline in survival rate. Those exposed to traffic dust particles showed significantly higher levels of oxidative stress and antioxidant activity than those exposed to other particles.
环境污染对现代社会水生生态系统的整体健康构成了重大而紧迫的威胁。本研究表明，以原始形式和组合形式暴露于盐水丰年虾的污染物，如 AC 过滤器、风扇叶片和交通粉尘 PM2.5。研究结果表明，暴露于多种污染物对盐水丰年虾卵的孵化率有不利影响。与未处理的盐水丰年虾相比，暴露于多污染物后，成年（第 7 天）盐水丰年虾的形态在每次孵育期（24-120 小时）后都发生了明显变化。与对照组相比，暴露时间从 24 小时增加到 120 小时，氧化应激显著增加。抗氧化酶活性和总蛋白浓度随时间呈下降趋势。当所有颗粒一起使用时，盐水丰年虾中的总蛋白含量显著下降。所有颗粒的存活率都明显下降。暴露于交通粉尘颗粒的个体的氧化应激和抗氧化活性明显高于暴露于其他颗粒的个体。
