Monitoring Changes in Airborne Bismuth Pollution and the Feasibility of Using Robinia pseudoacacia for Pollution Reduction

Air pollution is one of the greatest threats to human health on a global scale today. Heavy metals, in particular, are harmful air pollutants even at low concentrations. Therefore, monitoring changes in the concentration of heavy metals in the air and reducing pollution are priority research topics. In this study, the feasibility of using Robinia pseudoacacia, cultivated in Düzce, where heavy metal pollution is known to be high, to monitor changes in Bi pollution in the air and reduce it was investigated. Within the scope of the study, changes in Bi concentration were evaluated based on organ, direction, and age range over the last 60 years. The study concluded that Bi pollution in the region is largely due to agricultural activities. The study determined that Robinia pseudoacacia is not a suitable species for monitoring changes in Bi pollution but can be used to reduce pollution.
