Spatial Variation in Integrated Geochemistry and Microbial Community Structure of Waste Dump Sites in Lagos, Nigeria

Research Details

Deducing the microbial community structure in waste dumpsites exposed to different kinds of pollutants is essential for identifying the groups that may be adversely affected by pollution and those that may serve as degraders of persistent organic pollutants in the polluted soil samples. Soil samples from three different waste dump sites Cele, Solous, Computer village which have a history of long-term exposure to all manners of pollutants were characterized for a range of physicochemical properties, and microbial community structure was deduced using Illumina sequencing of the 16S rRNA gene. Pyrene and dibenzofurans DF , a model congener of dioxins was detected only in Cele and also had the highest level of total polycyclic aromatic hydrocarbons PAHs and other persistent organic compounds contamination, while heavy metal concentration not of serious environmental public health concern was highest in Computer village which was the least polluted site. The physio-chemical properties indicated some variances between the three different waste dumpsites. Microbial diversity in Cele and Solous soils was reduced compared to Computer village site. In Computer village Gammaproteobacteria were minor constituents while the major phylum were Actinobacteria, Acidobacteria, Chloroflexi and Planctomycetes which were minor in Cele and Solous. Proteobacteria and Firmicutes were the dominant phyla in Cele while Bacteriodetes and Proteobacteria were the dominant phyla in Solous.The diversity of the soil bacteria was distinctively separated along the principal coordinate axes in the three different waste dumpsites. These results have clearly indicated the importance of combining both genomic profiling and physico-chemical properties of soil for monitoring soil bacterial ecosystem, which could serve as a guide for further studies on tropical soil remediation and proffer new indicators pertaining to bacterial diversity pattern between the varied types of waste dumpsites exposed to different pollutants.
