This study analyzes the effects of acetaminophen (APAP) as a contaminant on physiological characteristics of lettuce plants ( L.). Experiments were provided in an experimental greenhouse with semi-controlled conditions. The effect of different amounts of contaminant was evaluated by using regression analysis. Plants were grown in five concentrations of APAP: 0 µM, 5 µM, 50 µM, 500 µM, and 5 mM for 14 days in two variants, acute and chronic. The obtained results show that the monitored parameters were demonstrably influenced by the experimental variant. Plants are more sensitive to chronic contamination compared to acute. Significant ( < 0.05) deviation in photosynthesis and fluorescence was observed compared to the control in different variants. The highest doses of APAP reduced the intensity of photosynthesis by a maximum of more than 31% compared to the control. A reduction of 18% was observed for the fluorescence parameters. Pronounced correlation was described between chlorophyll fluorescence parameters and yield mainly under APAP conditions. The amount of chlorophyll was influenced by exposure to APAP.
本研究分析了对乙酰氨基酚（APAP）作为污染物对生菜植株（L.）生理特性的影响。实验在半控制条件的实验温室中进行。通过回归分析评估不同量污染物的影响。植株在五种浓度的APAP（0 µM、5 µM、50 µM、500 µM和5 mM）下生长14天，分为急性和慢性两种变体。所得结果表明，监测参数明显受实验变体的影响。与急性污染相比，植株对慢性污染更敏感。在不同变体中，与对照相比，光合作用和荧光出现显著（<0.05）偏差。与对照相比，最高剂量的APAP使光合作用强度最大降低超过31%。荧光参数降低了18%。主要在APAP条件下，叶绿素荧光参数与产量之间存在显著相关性。叶绿素含量受APAP暴露的影响。
