“…The pollution impact of the regulated contaminants -As, Cd, Se, Pb, Ni, Cr, Cu, and Zn -in the chosen organic fertilizers was modeled using FCA. This approach is suitable for extracting transparent, systemic, reliable, and logical information from vague or uncertain data; and it involves the adoption of fuzzy reasoning techniques to create a membership function matrix that is subsequently subjected to a weighted average assessment [25,38].…”

“…Unarguably, and to the best of the authors' knowledge, it is obvious that the majority of the researches on the reporting and comparing pollutants' concentrations with known standards. This approach promotes vagueness and inconsistency in data quality and as such prevents the establishment of the combined environmental impact of the contaminants, suitable for impact rating and comparative assessment, as well as the evaluation of the individual contribution of these pollutants [25]. There is therefore the need to adopt novel and advanced methodologies to ascertain these impacts and solves the aforementioned deficiencies of the conventional method; this can be achieved using suitable approaches such as fuzzy comprehensive assessment (FCA).…”

In the quest towards achieving the Zero hunger agenda of the sustainable development goals by 2030, the utilization of organic fertilizers, for soil amendment purposes, has been posited as a feasible alternative for overcoming the negative impacts of inorganic fertilizers. Despite its manifold benefits, the use of untreated and improperly treated organic materials in agricultural production is however capable of introducing toxic metals in the soil-plant systems causing health and agro-environmental impacts. In this study, available organic fertilizers use by Nigerian farmers were selected and analyzed for nutrient values and most importantly, heavy metal contamination. The degree of contamination in each sample was modeled using fuzzy comprehensive assessment. The manure samples possessed optimum nutritional values; the nitrogen, phosphate, and potash contents ranged from 0.91 – 7.44, 0.06 – 1.61, 0.14 – 0.58% respectively. The fuzzy algorithm results categorized all the organic fertilizers as pristine, with a membership degree ranging from 35 to 99%. However, an excessive level of toxic contamination, with a membership function between 3 to 33% was observed. The major contaminants were identified as Zn, Cr, and Cd with an individual contribution of 16, 29, and 33% respectively. Adequate remediation techniques and good management practices that reduce the concentration of heavy metals in the organic fertilizers especially that of Zn, Cr, and Cd, should therefore be promoted among the producers and users of these soil improvers in Nigeria.

This study presents the effects of environmental pollution on the quality of domestic roof-harvested rainwater (DRHRW) using fuzzy comprehensive assessment (FCA). Seven metals (Cu, Cd, Pb, Zn, Fe, Ca, and Mg) and six water-quality parameters (Acidity, PO4 (3-), SO4 (2-), NO3 (-) , Cl(-), and pH) were investigated in DRHRW sampled from 12 sampling points each from Ibadan (residential) and Lagos (industrial) environments, Nigeria. The results of these parameters were formulated into membership function fuzzy matrices based on four contamination classifications of high, marginal, low, and poor qualities using regulatory limits as criteria. The products membership function matrices and weight matrices generated indices that classified the degree of anthropogenic activity impact on the sites. Results of FCA classified the DRHRW from residential environment as between high and marginal quality, whereas DRHRW from industrial environment is classified between marginal and low quality. Lead and Cd were major contaminants of concern found in these harvested water.

We present a modelling concept for evaluating the impacts of anthropogenic activities suspected to be from gas flaring on the quality of the atmosphere using domestic roof-harvested rainwater (DRHRW) as indicator. We analysed seven metals (Cu, Cd, Pb, Zn, Fe, Ca, and Mg) and six water quality parameters (acidity, PO, SO, NO Cl, and pH). These were used as input parameters in 12 sampling points from gas-flaring environments (Port Harcourt, Nigeria) using Ibadan as reference. We formulated the results of these input parameters into membership function fuzzy matrices based on four degrees of impact: extremely high, high, medium, and low, using regulatory limits as criteria. We generated indices that classified the degree of anthropogenic activity impact on the sites from the product membership function matrices and weight matrices, with investigated (gas-flaring) environment as between medium and high impact compared to those from reference (residential) environment that was classified as between low and medium impact. Major contaminants of concern found in the harvested rainwater were Pb and Cd. There is also the urgent need to stop gas-flaring activities in Port Harcourt area in particular and Niger Delta region of Nigeria in general, so as to minimise the untold health hazard that people living in the area are currently faced with. The fuzzy methodology presented has also indicated that the water cannot safely support potable uses and should not be consumed without purification due to the impact of anthropogenic activities in the area but may be useful for other domestic purposes.
