Usage of Robinia pseudoacacia and Cedrus atlantica in Monitoring and Reduction of Change of Niobium Pollution in Air

In this study, it was aimed to monitor the change in niobium (Nb) pollution, one of the heavy metals that can be harmful and toxic for human and environmental health, and to determine the usability of Robinia pseudoacacia and Cedrus atlantica species, which were determined to be biomonitors, in reducing Nb pollution.Within the scope of the study, samples were taken from the main stem of Robinia pseudoacacia and Cedrus atlantica, which grow under similar growing conditions in Düzce province, which is among the 5 most polluted cities in Europe according to the 2021 World Air Pollution report, and Nb concentrations were determined. As a result of the study, it was determined that Cedrus atlantica is suitable for monitoring the change in Nb concentration and Robinia pseudoacacia is suitable for reducing Nb pollution.
