“…Two perennial floating plants, A. filiculoides and L. minor , were studied regarding their ability to accumulate Cu within 7 days. A. filiculoides belongs to the Salviniaceace family ( Dohaei et al., 2020 ) while L. minor on the other side belongs to Lemnaceae family ( Ifayefunmi et al., 2021 ). Both plants have the ability to grow fast ( Sathish et al., 2022 ) with high growth rate of 0.5 day −1 and doubling biomass time of 2 days ( Chakrabarti et al., 2018 ; Dohaei et al., 2020 ).…”

“…The current method for duckweed frond quantification mainly revolves around manual counting [ 23 , 24 ], the implementation of ImageJ [ 25 ], and paid software [ 26 , 27 ]. ImageJ helps with the quantification process as it is possible to measure the area covered by duckweed and the number of duckweeds.…”

In recent years, there have been efforts to utilize surface water as a power source, material, and food. However, these efforts are impeded due to the vast amounts of contaminants and emerging contaminants introduced by anthropogenic activities. Herbicides such as Glyphosate and Glufosinate are commonly known to contaminate surface water through agricultural industries. In contrast, some emerging contaminants, such as rare earth elements, have started to enter the surface water from the production and waste of electronic products. Duckweeds are angiosperms from the Lemnaceae family and have been used for toxicity tests in aquatic environments, mainly those from the genus Lemna, and have been approved by OECD. In this study, we used duckweed from the genus Wolffia, which is smaller and considered a good indicator of metal pollutants in the aquatic environment. The growth rate of duckweed is the most common endpoint in observing pollutant toxicity. In order to observe and mark the fronds automatically, we used StarDist, a machine learning-based tool. StarDist is available as a plugin in ImageJ, simplifying and assisting the counting process. Python also helps arrange, manage, and calculate the inhibition percentage after duckweeds are exposed to contaminants. The toxicity test results showed Dysprosium to be the most toxic, with an IC50 value of 14.6 ppm, and Samarium as the least toxic, with an IC50 value of 279.4 ppm. In summary, we can provide a workflow for automatic frond counting using StarDist integrated with ImageJ and Python to simplify the detection, counting, data management, and calculation process.
