Toxicological Characterization of Nigerian Bituminous Coal Fly Ash and Priority Assessment of the Potential Applications Based on the Concept of Industrial Ecology | Chapter 03 | Recent Advances in Biological Research Vol. 1
The impact of coal fly ash (CFA)
exposure to the ecosystem and human health has not gone unnoticed. Is quiet
very obvious that CFA disposal will continue unabated and will continue to
constitute a menace to the ecosystem as the demands for energy soured-up. This
is expected as the utilization and exploration of dormant coal deposits will
take a comeback into the energy master-plan of most developing economies. As a
fallout of these demands, the health risk associated with CFA, particularly as
regards the Nigerian bituminous CFA were reported in this study. Albino rats
were separately administered coal fly ash sample burned at a temperatures of
500°C and 900°C. The assumption is to get more insight whether coal burning
temperature participated in defining the underlying susceptibility of CFA
toxicity. The in vivo study shows the CFA at both ashing temperature exerted
similar effect on both the biochemical indices and the histological section of
the rats, suggesting the effects to be independent of the temperature at which
samples were burned. Even though, the CFA were observed to trigger toxic
induced effects, the chapter picture the CFA generated from coal combustion
processes as an integral components of a productive cycles than a menace. A
resources for other applications and a sink that may act to absorb or detoxify
waste. This chapter attempt to establish an ecological symbiosis between the
CFA generated as a waste to environmental sustainability by closing material
cycle in concert with the ecosystem based on the concept of industrial ecology.
The expectations are that the impact of the chapter will influences changing
post-processing materials from coal combustion processes from waste to
resources. The Nigerian bituminous CFA sample collected at two different ashing
temperatures of 500°C and 900°C produced similar biochemical and histological
effects. The analyses showed that the effects were not dose and ashing
temperatures dependent. Attributed, more probably to the combustion efficiency
rather than coal type and fly ash sampling temperature. And more probably to
the ability of both the organic and inorganic constituents of the CFA to
initiate and induce the formation of free radicals, particularly activated
reactive oxygen species, by Fenton-like reaction. To ameliorate the
environmental-related concerns of CFA on the ecosystem, the concept of
industrial ecology were discussed in line with natural concept of ecology.
Placing emphasis on CFA utilization in soil amendment and reclamations, in
agriculture, as adsorbents materials, in catalysis, in ceramics and in
concretes. The assumption is that changing post-processing materials from waste
to resources will reduce economic cost and environmental impact of effluent
like CFA.
