The joint Pakistan-China study, published this month in Chemosphere, is based on spectroscopy (an approach used by Chemists to detect very small amounts of an element) of water, sediment and fish samples collected from sites along the Chenab, Indus and Kabul rivers and analysed at the Institute of Tibetan Plateau Research (ITPR), Beijing.
