DETERMINATION OF TRACE ELEMENTS IN ATMOSTPHERE OF DALAT CITY THROUGH BARBULA MOSS USING THE TOTAL REFLECTION X-RAY FLUORESCENCE
Main Article Content
Abstract
An assessment of environmental pollution is a concern for all countries in the world, especially developing countries, including Vietnam. Air pollution are mainly from three sources: the production process of factories and enterprises; pollution from chemicals in agricultural production; and pollution from vehicles. This research used Barbula moss, which is considered as a bio-monitor. Barbula moss is a short plant without true root, so it absorbs nutrients through leaves and stems. Barbula moss can absorb metals in the air. Barbula moss is very large and grows naturally in Dalat city. Moss sampling in this study was collected from areas with vehicles and agricultural production. Using the total reflectance X-ray fluorescence (TXRF) method, 21 trace elements were found in moss samples with a very low concentration of some heavy metals.
