Assessment of trace metal elements in selected Plants around the vicinity of Ebedei Gas Flaring Station located at Ebedei Village, Ukwani Local Government Area, Delta State, Nigeria

This study evaluated the trace metal elements in selected plants around the Ebedei Gas Flaring Station, Ukwani Local Government Area, Delta State, Nigeria. The plants analyzed include Azadirachta indica, Cymbopogon citratus, Moringa oleifera, Carica papaya) and Alstonia boonei. The analysis revealed that Alstonia boonei had the highest concentration of Copper at 6.87 mg/kg, while the lowest concentration of Lead (0.06 mg/kg) was found in Carica papaya. The trace metal levels in the plants ranged from 0.06 mg/kg for Lead to 6.87 mg/kg for Copper, with Azadirachta indica showing moderate levels across all measured metals. These concentrations were within the permissible limits set by WHO for vegetables, indicating no immediate threat to consumers. However, the study highlights the potential for bioaccumulation over time, which could elevate these levels and pose health risks. The study thus recommends conducting regular monitoring of trace metal levels in plants around gas flaring sites to prevent potential health hazards. In addition, soil remediation strategies should be implemented to reduce metal uptake by plants and public awareness campaigns should be carried out to educate the local population on the risks of consuming plants from contaminated areas.
