Physical and Chemical Condition, Metal Material, and Possible Environmental Risk of Hydrated Peri-Urban Farms in Ilorin, North-Central, Nigeria

Abstract :
Standard analytical techniques were used to examine the physicochemical features of soils and irrigation water as well as a few specific heavy metals in thirteen peri-urban garden soils in Ilorin, Kwara State. The analyses were conducted to look into the soils and irrigation water of the gardens' potential ecological risks. The findings demonstrated that, with the exception of turbidity (88.67 mg/l), which was greater than the advised standard limit, all of the examined physicochemical parameters for agricultural soils and water were within the WHO standard limits. The majority of the water samples utilized for irrigation in both seasons were contaminated with cadmium and lead, and the soils indicated a potential for substantial cadmium deposition. This suggested there may be a health risk from eating crops that have been irrigated using water from these sources When the study's data were analyzed, it was discovered that there were substantial variations in the parameters between sites and seasons (p 0.05). There were also generally low to moderate potential ecological concerns associated with metals in soils across sites. From site to site and from one season to the next, the physicochemical characteristics and heavy metal concentrations of the soils and irrigation water used in the gardens exhibited noticeable fluctuations and non-uniform distribution.
