“…It can be seen that the nitrate values are generally higher than the stipulated limit by the National Standard for Drinking Water Quality, except in sample WSP-4. This is an indication of the leaching of unlined wastes from nearby waste dumpsites and auto-mechanic workshops within the auto-mechanic village into the studied river [44][45][46]. The high nitrate concentration recorded in the Otamiri River implies that consumption of the water could lead to the development of methaemoglobinaemia (blue baby syndrome) in infants [1,37,40].…”

Surface water monitoring is essential, especially when the water is normally used for industrial, agricultural, and domestic purposes. The study determined the physicochemical properties of the River Otamiri using the American Public Health Association standard methods for water analysis. In this study, river water samples were collected five times during the dry season from four sampling points (WSP-1, WSP-2, WSP-3 and WSP-4) along the watercourse of the river in Owerri West Local Government Area of Imo State. The levels of the selected physicochemical parameters were compared with the National Standard for Drinking Water Quality (NSDWQ) guidelines. The findings showed that the pH (4.99±0.11 – 6.30±0.08), dissolved oxygen (4.16±0.01 – 6.45±0.03), total hardness (17.10±1.78 – 27.80±2.54), chloride (68.30±0.58 – 91.90±0.64), and sulphate (39.55±3.32 – 51.21±2.11) were below the acceptable limit of the National Standard for Drinking Water Quality (NSDWQ). However, electrical conductivity (1116±29.75 – 1419±28.54), turbidity (18.90±2.81 – 31.70±8.13) and nitrate (45.50±3.06 – 69.90±2.11, except in water sample point-4) were above the recommended limit according to the NSDWQ guideline, while temperature levels (26.90±0.04 – 28.40±0.02) were within the acceptable limit. The study concludes that the River Otamiri is contaminated. It is therefore advisable to purify water from the river before use for domestic and industrial purposes.

“…The used oil contains substantial amounts of hydrocarbons, including the highly toxic polycyclic aromatic hydrocarbons (Wang et al, 2011). Industrial activities, particularly automotive maintenance and repair, frequently contribute to the release of engine oil effluents into the environment ( Nkwoada et al, 2018). These effluents, containing various pollutants such as heavy metals and hydrocarbons, have the potential to contaminate soil and water resources (Ayotammo et al, 2006).…”

The improper disposal of waste engine oil effluent onto gutters, open lands, and cultivated farm lands is a common practice in Nigeria, especially among mechanics. These effluents contain substances derived from hydrocarbons that can diminish soil fertility and also influence the properties of plants. This study was consequently undertaken to examine the effects of waste engine oil on the nutritional, phytochemical, and antibacterial constituents of Telfairia occidentalis (Pumpkin leaf). Various levels (0ml, 100ml, 200ml, 300ml, and 400ml) of diesel oil contamination were mixed with 2 kilograms (kg) of soil, with each treatment replicated three times. Plants were watered daily for four months, and after 16 weeks, leaf samples were collected for laboratory analysis. The nutritional composition, phytochemical properties, and antibacterial components of the leaves were examined. The results indicated a significant reduction (P<0.05) in protein (12±0.02), fats (7±0.02), ash (15±0.25), fiber (10±0.03), and carbohydrate (10±0.25) content in the 400ml waste oil treatment compared to the control (0ml) values (protein: 38±0.01, crude fat: 25±0.13, total ash: 45±0.07, crude fiber: 36±0.15, carbohydrate: 42±0.04). Phytochemical analysis demonstrated a noteworthy decrease in alkaloids, saponins, flavonoids, and phenols as waste oil levels increased in the soil, compared to the control (0ml). The antibacterial activity screening revealed that among the various concentrations (80mg/ml, and 20mg/100 ml) of extracts studied, 80g/ 100 ml showed the highest degree of inhibition on all the test organisms. However, there was a notable reduction in inhibition as the level of waste oil pollution increased in the soil, compared to the control...

The study aimed to analyze the presence and dispersion of hydrocarbons in dumpsites at mechanic workshops in Port Harcourt, Rivers State, Nigeria. Soil samples were collected from within 15-25 cm soil depth from three mechanic workshops in Port Harcourt, situated at Elekahia, Rumeme and Eleme Local Governments. The total petroleum (TPH) and Polycyclic aromatic hydrocarbons (PAHs) concentrations in the soil samples were determined using standard methods. Total TPH concentration in mechanic workshop dumpsites ranged from 9508.18 ppm to 10342.41 ppm, while in the control the concentration was 424.41 ppm. Total PAH concentration in mechanic workshop dumpsites ranged from 312.45 ppm to 1654.08 ppm, while in the control the concentration was 157.89 ppm. All the dumpsites had high levels of PAHs, which was several folds more than in the control. Results revealed that soil at mechanic workshop dumpsites was highly contaminated with hydrocarbons, exceeding the allowable limit 50 mg/kg by the Department oof Petroleum Resources (DPR). Remediation of the soil is recommended, as well as proper management of waste, where relocation of the dumpsite is not possible.
