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;\">NO&lt;sub&gt;2&lt;/sub&gt;&lt;sup

style=\"margin-left:-7px;\"&gt;2-&lt;/sup&gt;</span><span style=\"font-family:&quot;\"><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;\">NO&lt;sub&gt;2&lt;/sub&gt;&lt;sup

standardized methods. Tomatoes from conventional agriculture had higher levels
of trace metal elements (0.163</span><span
