As such, an attempt was made to predict and validate contamination in nine separate sub-catchments of the Lourens River, South Africa, through use of a geographic information system (GIS)-based runoff model, which incorporates geographical catchment variables and physicochemical characteristics of applied pesticides. We compared the results of the prediction with measured contamination in water and suspended sediment samples collected during runoff conditions in tributaries discharging these sub-catchments. The most common insecticides applied and detected in the catchment over a 3-year sampling period were azinphos-methyl (AZP), chlorpyrifos (CPF) and endosulfan (END). AZP was predominantly found in water samples, while CPF and END were detected at higher levels in the suspended particle samples. We found positive (p &lt; 0.002) correlations between the predicted average loss and the concentrations of the three insecticides both in water and suspended sediments (r between 0.87 and 0.94). Two sites in the sub-catchment were identified as posing the greatest risk to the Lourens River mainstream. It is assumed that lack of buffer strips, presence of erosion rills and high slopes are the main variables responsible for the high contamination at these sites. We conclude that this approach to predict runoff-related surface water contamination may serve as a powerful tool for risk assessment and management in South African orchard areas.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-54986","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"\"SCHULZ R,TECH UNIV CAROLO WILHELMINA BRAUNSCHWEIG,INST ZOOL;FASANENSTR 3;D-38092 BRAUNSCHWEIG, GERMANY.r.schulz@tu-bs.de\"","annee":"2002","mois":"12","numero":"36:20","page":"4975-4984","auteurs":[{"ID":54981,"post_author":"0","post_date":"2018-12-04 06:53:23","post_date_gmt":"2018-12-04 05:53:23","post_content":"","post_title":"Dabrowski","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"dabrowski","to_ping":"","pinged":"","post_modified":"2018-12-04 06:53:23","post_modified_gmt":"2018-12-04 05:53:23","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/dabrowski\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":54982,"post_author":"0","post_date":"2018-12-04 06:53:24","post_date_gmt":"2018-12-04 05:53:24","post_content":"","post_title":"Day","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"day-2","to_ping":"","pinged":"","post_modified":"2018-12-04 06:53:24","post_modified_gmt":"2018-12-04 05:53:24","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/day-2\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":54983,"post_author":"0","post_date":"2018-12-04 06:53:24","post_date_gmt":"2018-12-04 05:53:24","post_content":"","post_title":"Peall","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"peall","to_ping":"","pinged":"","post_modified":"2018-12-04 06:53:24","post_modified_gmt":"2018-12-04 05:53:24","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/peall\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":54984,"post_author":"0","post_date":"2018-12-04 06:53:25","post_date_gmt":"2018-12-04 05:53:25","post_content":"","post_title":"Reinecke","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"reinecke","to_ping":"","pinged":"","post_modified":"2018-12-04 06:53:25","post_modified_gmt":"2018-12-04 05:53:25","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/reinecke\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":31167,"post_author":"0","post_date":"2018-12-03 23:41:30","post_date_gmt":"2018-12-03 22:41:30","post_content":"","post_title":"Mark R Schulz","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"mark-r-schulz","to_ping":"","pinged":"","post_modified":"2018-12-03 23:41:30","post_modified_gmt":"2018-12-03 22:41:30","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/mark-r-schulz\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":54985,"post_author":"0","post_date":"2018-12-04 06:53:26","post_date_gmt":"2018-12-04 05:53:26","post_content":"","post_title":"Van Niekerk","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"van-niekerk-2","to_ping":"","pinged":"","post_modified":"2018-12-04 06:53:26","post_modified_gmt":"2018-12-04 05:53:26","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/van-niekerk-2\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":15820,"post_author":"0","post_date":"2018-12-03 19:31:19","post_date_gmt":"2018-12-03 18:31:19","post_content":"","post_title":"WATER RESEARCH","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"water-research","to_ping":"","pinged":"","post_modified":"2018-12-03 19:31:19","post_modified_gmt":"2018-12-03 18:31:19","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/water-research\/","menu_order":0,"post_type":"source","post_mime_type":"","comment_count":"0","filter":"raw"}]},"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v23.6 (Yoast SEO v23.6) -
