Mercury distribution in an invasive species (Asystasia gangetica) from Peninsular Malaysia

In this study, the Hg levels in eight parts of Asystasia gangetica (L.) T. Anderson collected from 14 sites were determined using a Mercury Atomizer MA-1S and a Mercury Detector MD-1. It was found that the ranges for all the parts were 3.21-18.2 μg/kg dry weight for flowers, 1.29-11.2 μg/kg dry weig...
