DESCRIPTION:Speakers: Chazanne Long (AEON - NMMU)\nChemical signatures fro
 m river waters and sediments were collected in the Crocodile (West) and Ma
 rico Water Management Areas\, South Africa. Surface water samples were ana
 lysed for anion complexes using Ion Chromatography (IC) and major and trac
 e element chemistry using quadrupole Inductively Coupled Plasma-Mass Spect
 rometry (q-ICP-MS). Major and trace element chemistry was measured by XRF 
 and mineralogy by XRD on all sediment samples. The results are used to def
 ine the various chemical signatures resulting from activities within the s
 tudy area and to differentiate the ‘background’ that arises from natur
 al geological heterogeneity. The aim of this characterisation is to finger
 print the chemical signatures of various anthropogenic activities irrespec
 tive of background in order to gain an insight into the level of chemical 
 contamination by the receiving environment. Based on the results\, the con
 tamination sources within the area can be identified and ranked in terms o
 f the contribution to the total effective chemical contamination received 
 at Hartebeespoort Dam.\nKeywords: Heavy metal\, chemical fingerprint\, geo
 chemistry\, South Africa\n\nhttps://events.saip.org.za/event/40/contributi
