We report, the application of the photoacoustic technique for monitoring the photosynthesis evolution in aquatic lirium (Eichhornia Crassipes), before and after it was exposed to ultrasonic irradiations. We obtained the disappearance of the phototobaric contribution in the PA signal measured for the irradiated samples with ultrasound of 17 kHz, and therefore of a possible damage in the centers producing the photosynthesis, due to the irradiation. These results show the utility of the ultrasonic irradiation, as well as, of the photosynthesis monitoring by means of the photoacoustic technique, for the elaboration and establishment of methodologies in the control of this aquatic plant, whose propagation causes many consequences extremely unfavorable for the environment, as well as for the diverse human activities that are developed in the bodies of water in the tropical and sub-tropical regions of the world.
我们报告了光声技术在监测水生风信子（凤眼莲）暴露于超声辐照前后光合作用演变中的应用。我们发现，对于用17kHz超声辐照的样品，在测量的光声信号中光压贡献消失，因此由于辐照，光合作用产生中心可能受到了损伤。这些结果表明了超声辐照以及通过光声技术监测光合作用在制定和建立控制这种水生植物的方法中的实用性，这种水生植物的繁殖对环境以及世界热带和亚热带地区水体中开展的各种人类活动造成了许多极其不利的后果。
