Background: Vegetables are some of the edible plants mostly affected by environmental pollution and is of prime concern because it forms an integral part of many diets as a major source of essential minerals and vitamins. Insufficient consumption of vegetables has been listed as one of the risks factors contributing to the development of many degenerative diseases. Recently, researchers have developed interest in the pharmacological role of vegetables in fighting harmful biological processes of inflammation and overcoming nutritional problem. The present study was carried out to assess the physicochemical characteristics of vegetables obtained from markets, located in Ogoniland and Ozubulu, where cultivation and marketing of vegetables is a major occupation of the people. Materials and Methods: Seven (7) commonly consumed vegetables were used for the study. They were randomly obtained from the local markets within the study area, cleaned and their physicochemical parameters investigated using standard methods as contained in AOAC, (2006). Results: There was significant (t= 3.40, p= 0.03) decrease in pH and significant (t=8.09, p=0.00) decrease in ascorbic acid (vitamin C) content of the vegetables consumed in Ogoniland (7.45 ± 0.55 and 144.39 ± 21.66 mg/100g respectively) compared to those consumed in Ozubulu (8.20 ± 0.55 and 207.24 ± 27.65 mg/100g respectively). There was significant (t= 2.45, p= 0.02) decrease in Mg levels and significant decrease (t= 2.39, p= 0.03) in Ca levels of the vegetables from Ogoniland (3782.00 ± 455.10 and 3509.29 ± 618.93 mg/kg respectively) when compared to Ozubulu (4982.38 ± 767.14 and 4326.86 ± 907.08 mg/kg respectively). The result also showed significant (t=1.24, p= 0.03 and t=3.78, p=0.01) increase in sulphates (6924.88 ±1393.08mg/kg) and chlorides (2030.70± 234.85mg/kg) levels and significant decrease (t=1.70, p=0.11 and t= 4.35, p= 0.00) in nitrates (118.40±7.18mg/kg) and phosphates (97.33 ±3.02mg/kg) levels of vegetables from Ogoniland when compared to Ozubulu (5253.13 ±505.42mg/kg, 1768.90 ±208.33mg/kg) and ( 141.82 ±8.67mg/kg, 108.24 ±2.55mg/kg) respectively. The Pearson correlation indicated that pH, vitamin C and chloride showed strong significant negative correlation (r=-0.76, p=0.04, r= -0.98, p= 0.00 and r= -0.96, p= 0.00 respectively) while sulphates and nitrates showed moderate significant negative correlation (r= -0.56, p= 0.04 and r= -0.50, p=0.02 respectively). Conclusion: Vegetable samples collected from Ogoniland were more acidic and had lower micronutrient values compared to those from Ozubulu. This may be attributed to the environmental pollution of the area from crude oil activities. Soil and atmospheric pollution could contribute to nutrient deficiency in vegetables that may pose significant health risks to consumers.
