Dioxin emission and industrial solid waste in Kano metropolis, Nigeria

Abstract

This study assesses Dioxin and solid waste in Kano Metropolis, Nigeria. The main sources of Dioxin considered included products and residues, from production and waste combustion from tanneries, grain mills, upholstery, plastics, textiles, petroleum and metals industries. The study covered the four industrial zones of Sharada (zone 1), Bompai (zone 2), Challawa (zone 3) and Hadejia (zone 4) with about 225 major manufacturing industries in Kano State. Samples were collected in stages using stratified, purposive and random sampling methods. Questionnaire and checklist were used for data collection. Environmental compartments considered included air, water, land, products and residues for the year 2014. Descriptive statistics were used to analyze data on identification of relevant industries, and estimation of Dioxin emission potentials. The results obtained showed that tannery, milling, textile, metal, upholstery, petroleum and plastic industries were the maint sources of Dioxin emission within the study area, having extremely high potential releases of 92.1290380335gTEQ/A from 165 industries in Kano metropolis for year 2014. Tanneries potentially contributed 93.51% of the total emissions of Dioxin. The study found out that emission of Dioxin and related compounds reflects the poor pollution control and waste management practices been carried out by the industries.
