Acid mine drainage (AMD) is a sulfuric discharge containing metals and particulates that can spread to nearby water sources, imposing toxicity and physical stress to living things. AMD is formed due to the oxidation of iron pyrite and other sulfidic minerals exposed to water and oxygen due to mining operations. Under these conditions, the minerals release Fe, SO₄^2- and H^+[2]. Optical Coherence Tomography is a non-contact and non-invasive optical imaging technique that acquires tomographic images of samples. It was demonstrated that the biological activities of plant samples can be evaluated by bOCT in our previousstudy where we proposed to use biological signal obtained in OCT for the plant under O₃ stress using biospeckle OCT (bOCT)^[1]. In this study, the influence of the AMD on seed germination was monitored,using bOCT under different AMD concentrations.
