Mycological And Physicochemical Profiling Of Textile, Paper And Pulp Wastewaters From Lagos Industrial Zone

ABSTRACT

The increase in human population, activities and fast industrialization have results into severe pollution of water bodies and consequently on different aquatic lives. This study was undertaken to compare the physicochemical data of textile and paper and paper industrial effluents discharge with the Federal Environment Protection Agency (FEPA) as well as International (world Health Organization) discharge standards. Water samples were collected and analyzed for mycological and physicochemical properties using standard procedures and the quality compared using FEPA and WHO standards, respectively. The obtained data were also analyzed using two – way ANOVA and Dunnet comparison tool with significance threshold at 0.05. The results revealed that the both textile and paper and pulp wastewater samples were ambient in temperature, textile wastewater was alkaline while paper and pulp wastewater was acidic in pH. All the physical, chemical and fungal parameters ranging from colour to total fungal count except sulphate exceeded WHO (2004) and FEPA (1999) standard limits.  Also, all the heavy metals except zinc, nickel, manganese and cobalt were high in compositions of the textile and paper and pulp wastewaters and exceeded the FEPA (1999) standard limits. The analysis of variance on the samples of the industrial effluents showed that there are significant differences (P < 0.5) in the physiochemical characteristics as compared with the WHO (2004) and FEPA (1999) standard limits. The findings of this present study demonstrated the unacceptable statuses of these wastewaters, hence single or a combined treatment regimen is therefore recommended.
