Assessment of Trace Metals in the Leaves of Adansonia digitata and Eucalyptus globulus along Dutsinma Road in Batagarawa Local Government Area of Katsina State| Chapter 1 | Current Approaches in Science and Technology Research Vol. 3

 Using atomic absorption spectrophotometry, the burdens of seven trace metals, Mn, Zn, Pb, Cr, Co,

Ni, Cu, and Fe, were studied in the leaves of two tree plant species in the region of Batagarawa Local
Government Area in Katsina State. The tree plants were Adansonia digitata (Baobab) and Eucalyptus
globulus (Gum tree). The results showed the levels of metals (µgg-1 per dry weight) in baobab leaves
to be 46.00 (Mn), 23.50 (Zn), 2.00 (Pb), 12.50 (Cr), 12.00 (Co), 2.00 (Ni), 5.00 (Cu), and 82.50 (Fe)
while in gum tree leaves the metal concentration are as follows, 43.00 (Mn), 22.50 (Zn), 3.00 (Pb),
6.50(Cr), 16.00(Co), 2.00 (Ni), 2.50 (Cu) and 57.50 (Fe). Fe, Mn, and Zn were found to be highly
concentrated in the leaves of both plant species, while Ni, Cu, Cr, Pb, and Co were found to be
  Concentration is moderate. The findings revealed that baobab leaves contained more trace metals than gum tree leaves. The findings also revealed that the levels of cobalt and lead recorded were higher than the WHO's maximum allowable limit, but the levels of Fe, Mn, Zn, and Cu were lower. A continuous environmental protection update could be used to verify the reported higher levels. This finding suggests that the leaves of both plants could be used to detect trace metal pollution.
