dc.description.abstract | The increased usage of used car tires in the crafts Industry has led to an increase in number of cut
tire pieces exposed to the environment. Burning of tire pieces for fuel is one of the common
practices carried out to eliminate the tire pieces from the environment in Uganda. The practice
not only releases smoke to the environment, but also leaves ash from burnt tire pieces exposed to
environment. The study therefore seeks to assess the release of Lead and Zinc from the unused
cut tire pieces and ash from burnt tire pieces when left open to water and soil. A survey was
carried out to establish the percentage of usage of the tire in the crafts industry and what goes to
waste. Through digestion of tire pieces and Ash and testing the digested mixture with the atomic
absorption spectrometer, the composition of tire pieces and ash was determined. The effect of
surface area on release of Lead and Zinc into water from tire pieces and ash was done through
keeping the tire pieces of small size 8x10-5
mm, medium 4mm and tire Ash in water and testing
the water after21 days. Results from small size cut tire pieces showed that tires had 0.146mg/L
and 1.493mg/L of Lead and Zinc and medium had 0mg/L and 0.902mg/L of lead and Zinc. In the
same way Ash was found to contain 5.072mg/L and 160.551mg/L of Lead and Zinc respectively.
This indicated that the smaller the surface area, the more the release of these elements into water
and the larger the surface area the lesser the elements released into water. | en_US |
