摘要

Tomato is a market gardening product that plays an important nutritional and economic role in Burkina Faso. However, the bad use of pesticides for its production could have negative impacts </span><span style="font-family:Verdana;">consumers’</span><span style="font-family:Verdana;"> health. The objective of the present study was to assess the concentration of trace metal elements (Pb, Cd </span><span style="font-family:Verdana;">and</span><span style="font-family:Verdana;"> As), 15N isotopes (</span></span><span style="font-family:Verdana;">NO₂<sup style="margin-left:-7px;">-</sup></span><span style="font-family:Verdana;">,</span><span style="font-family:Verdana;"> NO₃<sup style="margin-left:-7px;">-</sup></span><span style="font-family:Verdana;">,</span><span style="font-family:Verdana;"> NH₄<sup style="margin-left:-7px;">+</sup></span><span style="font-family:Verdana;">) and phosphorus (</span><span style="font-family:Verdana;">PO₄<sup style="margin-left:-7px;">2-</sup></span><span style="font-family:""><span style="font-family:Verdana;">) in tomatoes according to cultivation practices. Thus, three tomato varieties (Mon</span><span><span style="font-family:Verdana;">gal F1, F1 Cobra 26 </span><span style="font-family:Verdana;">and</span><span style="font-family:Verdana;"> Roma F1) were grown using organic and conventional production methods on 2 sites at Nongr Massom, (commune of Kadiogo province). The trace metal el</span></span><span style="font-family:Verdana;">ements were analyzed using atomic absorption spectrophotometry, the isotopes 15N (</span></span><span style="font-family:Verdana;">NO₂<sup style="margin-left:-7px;">-</sup></span><span style="font-family:Verdana;">,</span><span style="font-family:Verdana;"> NO₃<sup style="margin-left:-7px;">-</sup></span><span style="font-family:Verdana;">,</span><span style="font-family:Verdana;"> NH₄<sup style="margin-left:-7px;">+</sup></span><span style="font-family:Verdana;">) and pho
