. The results showed high concentration of chromium and low concentration of copper. The high chromium content is probably as a result of the large scale tanning going on at Challawa Industrial Area in Kano State, resulting in high deposit from wet blue shavings, leather trimmings and buffing cakes. These incinerated wastes could be collected, acidified and re-used for tanning, to give good hydrothermal stability to the resultant leather, thereby reducing the health hazard associated with chrome to the environment.&picture=http://www.aascit.org/aascit/decorators/img/journal/805.jpg)

Tanning Industry has contributed immensely in contaminating the environment with heavy metals due to the large quantity of chemicals employed in the tannery. These metals are introduced into the body through industrial stack gas, soil and ground water and have cumulative effects. This paper, determined concentration of some heavy metals in the tannery wastes with the view to generate empirical data showing various levels of heavy metals in the waste and also to create awareness of their effects on the environment and how to reduce them. In this paper, Incinerated tannery wastes collected from different dump sites in Challawa were analyzed for their chromium and copper heavy metal contents using Atomic Absorption Spectroscopy (AAS). The results showed high concentration of chromium and low concentration of copper. The high chromium content is probably as a result of the large scale tanning going on at Challawa Industrial Area in Kano State, resulting in high deposit from wet blue shavings, leather trimmings and buffing cakes. These incinerated wastes could be collected, acidified and re-used for tanning, to give good hydrothermal stability to the resultant leather, thereby reducing the health hazard associated with chrome to the environment.
