Abstract
Industrial growth is being attributed with adverse environmental effects and has
necessitated stricter environmental management policies. Formulating such
policies is limited by the difficulty in understanding the trends of monitoring
data. This study is aimed at the application of fuzzy comprehensive assessment
(FCA) to integrate environmental contaminants in Agbara industrial estate,
Nigeria, to measure the extent of impact of industrial activities on the host
community. Samples of water, plants (Pteridium aquilinum, Sacciolepis africana,
and Panicum maximum), soil, and sediments were collected within the estate.
Water samples were analyzed for quality parameters using standard methods.
Metals (Co, Cr, Cd, Cu, and Mn) were investigated in all the samples using an
atomic absorption spectrophotometer. The data were modeled with FCA. The
results showed Cr as the major contaminant (34–252 mgL1
). High phosphate
contributed to large plant growth in the area. FCA results showed that water
samples were in the pristine classification; sediment samples were extremely
impacted. The vegetation growth and the sediment precipitation were responsible
for the cleaning-up of the pollutants discharged downstream. The FCA of the
plants indicated high metal bioaccumulation and not only showed the plants’
phyto-remediation potential but also that the metals may pose threats to human
health through the food web. The activities in the estate are contributing
contaminants to the environment with potential negative effects.
