| Abstract | Currently, the airborne heavy metal pollution is the worldwide problem. Some kinds of plants are capable to trap heavy metal in the environment. Spanish moss (Tillandsia usneoides L.) is chosen to this research not only to be the passive sampler for heavy metal in the air but also measurement of the quantitative ratio of the Mercury's adsorption to absorption. T. usneoides L. is capable to be used as the environmental biomonitor. It will be divided into 4 sets placed at the four corners of the Gas Separation Plant, Songkhla for 6 months (May to October, 2014). Every month, sample sites will be analyzed by the Inductively Coupled Plasma Optical Emission Spectrometer (ICP-OES), cold vapor Atomic Absorption Spectrometry (AAS) and Scanning Electron Microscopy (SEM) techniques. The results showed that there was 4.30 ? 0.05 mg of Pb per kg of plant whereas the other heavy metals i.e. Cd, and Hg were not found. |
