Occupational exposure to petroleum products and its effects on heavy metal metabolism in automobile mechanics

This work assessed the presence of heavy metals in water contaminated with petroleum products in Keffi Local Government Area. Two water sampling station were selected based on the stratified method of sampling of Antau River. Station A is located along Federal Government College Keffi popularly known as Antau Bridge where Agricultural and mechanical activities, with sales of petroleum product take place. Station B was located at Dadin Kowa known as Gada Manu where human activities such as bathing and washing takes place which served as control. The distance between stations is 1km. The procedural plan of this study was monthly sampling of water from both Stations. Materials such as funnel, sampling container, distilled water, conical flask, filter paper, 50ml polypropylene centrifuge tube, cooler were used. Heavy metal concentration was determined using X – ray Fluorescent Spectroscopy (XRF) at the Center for Energy Research and Training (CERT), Ahmadu Bello University Zaria. The water parameters of the four samples were determined using the Extech instrument. The result on Physico – chemical parameters revealed the values obtained from contaminated water samples to be pH (7.31), Dissolved Oxygen (1.14), Electrical Conductivity (8.22), Total Dissolved Solid (4.13), Temperature (27.45) and Salinity (0.091) while the controlled Station at point B were pH (7.43), DO (7.35), EC (3.14), TDS (1.54), Temperature (26.75), Salinity (0.o94) respectively. From the result obtained, the heavy metal contaminated samples had the following values: Mg (29.31±), Al (218.69±), Si (230.12±), S (1153.65±), Cl (54.25±), Ca (106.56±), Ti (23.66±), Cr (3.15±), Fe (15.92±), Cd (7.54±). For the control sample at point B, the following values were obtained: Mg (27.49±), Al (223.71±), Si (243.21±), S (94.84±), Cl (23.52±), Ca (28.44±), Ti (32.99±), Fe (16.63±), Cd (7.67±) respectively. The P-value was 0.8105 (p>0.05) for the water quality parameters while for the concentration of heavy metal P-value was 0.2054 (p>0.05). This implies that there was no significant difference between the concentrations of elements. However, the concentration values of heavy metals in the contaminated water at Station A and control water samples at Station B were higher than the World Health Organization values (Standard) for drinking water

Introduction: Benzene, toluene, xylene and ethylbenzene (BTEX) are the most important aromatic compounds in petroleum products. Due to high vapor pressure, BTEX compounds easily change to gas form and mixed with ambient air. Petroleum products loading workers are exposed to these compounds by the inhalation of BTEX compounds. The aim of this study was to evaluate the effects of respiratory BTEX exposure on lung function indicators . Materials and Methods: A cross sectional study was conducted on petroleum products loading workers in 2015 until 2016. there were process of inclusion and exclusion in working tasks. 32 people participated in this study consciously. Eighteen samples of air was gotten in the breathing zone of workers. Sampling was performed by indivial sampling pump 222-4 model by use of activated charcoal were taken to determine the workers' exposure to benzene, toluene, xylene and ethyl benzene. Method of sampling was 1501 NIOSH.To determine and evaluate the lung function, spirometry tests were performed according to OSHA protocols. Results: The results of analysis of samples showed that the average exposure to benzene was above the occupational exposure limit and the average exposure to ethyl benzene, toluene and xylene were below the occupational exposure limit. Lung functions indices, including FVC, FEV1, FEV1 / FVC were reduced. Conclusion: The results showed that exposure to BTEX compounds could affect lung function indices, and reduced Lung functions indices.

Heavy Metal Bioaccumulation

A wide range of inorganic and organic compounds such as combustibles, and putrescible substances, hazardous waste, explosives, petroleum products and heavy metals (HM) can cause contamination. In addition, the non-biodegradability of heavy metals further exacerbates environmental pollution with its attendant health consequences on the biotic components of the ecosystem including humans. The use of living organisms such as plants and microbes is increasingly becoming acceptable practice of sustainable environmental sanitation. However, identification of potential bioremediation agents is still challenging. This study was carried out to bridge this gap by assessing heavy metal bioaccumulation properties of Calopogoniun Muconoides and Senna obtusifolia plants at contaminated site of mechanic workshop (site 1) in comparative to a physically non-contaminated site (site 2) within Makurdi metropolis of Benue State Nigeria. The selected plants were obtained from both sites and evaluated for their bioaccumulation capacities using standard procedures. The results revealed the sample plants accumulated high levels of heavy metals particularly in the leaves and roots, suggesting the utilization of phytoextraction, phytostabilization and phytovolatilization mechanisms of remediation. The plants and HM generally presented an order of concentration and bioaccumulation as: Senna obtusifolia > Calopogonium Muconoides; Zn > Fe > Pb > Cu > Cd > Cr > Ni. These findings suggest that these novel plants, especially Senna obtusifolia are good agents of bioremediation of heavy metals. Studies involving isotopic labeling to determine the exact mechanism of remediation as well molecular techniques such as transcriptomics and proteomics to identify genes/molecules that confer phytoremediation potential on the plants would be the next focus of our research in this emerging field of environmental biochemistry.
