Determination of sixteen woody species’ ability to sequester Sr, Mo, and Sn pollutants

This study aimed to determine the most suitable woody species that can be used to reduce the pollution of Sr, Mo, and Sn, which are heavy metals that are harmful to the ecosystem and human and environmental health. Within the study’s scope, samples were taken from the wood parts of 16 woody species growing under similar conditions in Düzce province, which is among the five cities with the most polluted air in Europe. The wood part is the largest organ of higher plants in terms of mass; it traps heavy metals within itself for many years and can remove heavy metals to a great extent. Therefore, plants with a high potential for heavy metal accumulation in the wood part are among the most suitable plants for phytoremediation studies. The study determined Sr, Mo, and Sn concentrations in the wood parts of 16 tree species via inductively coupled plasma optical emission spectroscopy and compared them using statistical methods. Results indicate that Robinia pseudoacacia and Cedrus atlantica species were suitable for reducing pollution by Mo and Sn, while Platanus orientalis and Populus alba species were suitable for reducing Sr pollution.
