“…Water pollution occurs when a body of water receives excessive amounts of materials called contaminants, such that the quality of the water becomes adversely affected (Olabemiwo et al, 2011). Organic polluted water causes aquatic-toxicological effects which are deleterious to aquatic life (Carls et al, 1999).…”

Bitumen exploration was flagged off at Irele, a Nigerian field in 2003. The relationship between the seepage pollutants and receiving water bodies is the focus of this study. We hereby present the polycyclic aromatic hydrocarbons (PAHs) level in two categories of bitumen contaminated waters; source (RS) and delivery (RD) points. Results were compared with uncontaminated water (RC) as control experiment. The PAHs were extracted by Liquid-Liquid extraction using dichloromethane and analyzed by Gas chromatography with mass spectrometer detector (GC-MS). The mean concentration of PAHs was 8.39, 3.93 and 0.57 ppb for source, delivery point and control respectively. The Benzo[e]pyrene concentrations obtained were higher than 1-10 ppb in most samples, indicating anthropogenic and petrogenic sources of the pollutants. Most of the PAH concentrations obtained were within natural concentrations, However, Benzo (e) pyrene and Indenol (1, 2, 3 – cd) pyrene exceeded the expected limit. The predominance of 4-6 member ring showed that the PAHs were more of pyrolytic than mixed sources. Method validation gave the Limit of Detection (LOD) and Limit of Quantification values in the range of 0.03-0.12 and 0.10-0.61 respectively. The Pearson product moment correlation (PPMC) coefficient (r) was used to determine the interactions of the PAHs detected with parametric factors. All the physicochemical parameters studied except pH shows positive correlation. Statistical test at P <0.05 indicated that the difference in PAHs concentrations is not significant when compared with maximum acceptable PAHs concentration (MAC) for water, which is an indication that the water is safe.Bangladesh J.

Background: Asphalt is a mixture of aliphatic and aromatic hydrocarbons. It also contains different kinds of heavy metals. Hot mix asphalt emits hazardous volatile substances. Asphalt is used in many industries, causing serious adverse health effects for workers. Therefore, investigation of the health status of workers is of crucial importance. The present study aimed to assess the impact of asphalt vapor on hepatic and renal function tests parameters and the clinical parameters in road paving workers compared to healthy subjects. Methods: In a cross-sectional study, 41 road asphalt paving workers and 120 healthy non-exposed subjects were selected. The serum enzymes of aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), total bilirubin, triglyceride, urea, and creatinine levels were assessed using diagnostic kits. A medical practitioner examined all subjects for any possible medical condition. Results: Liver and kidney function test parameters were significantly higher in road asphalt paving workers compared to their healthy counterparts (P<0.05 for all parameters). About 63% of workers exposed to asphalt fumes for more than 10 years showed cardiac, pulmonary, and metabolic complications. Conclusion: Significant elevations in liver and kidney function test parameters suggest that exposure to asphalt fumes is associated with hepatic and renal dysfunction in asphalt-exposed workers.

Polymer modified bituminous thick coatings are increasingly used in the construction industry to protect underground parts of buildings from groundwater. When assessing their durability, one vital issue related to their functional properties is the influence of water absorption on the waterproofness of the applied solution as a result of the action of groundwater with different pH values. As part of the research, the water absorption of the products in question was assessed using the method of total immersion in water with pH of 4.0, 7.0 and 7.5 as well as comparatively, as a result of one-way exposure to demineralized water under successively increasing pressure up to 0.5 MPa. The moisture susceptibility of the coatings was assessed both concerning the local surface damage and the continuous waterproofing coating. It was established that the coatings show the highest water absorption when the water pH is 4.0, which simulates the groundwater aggressiveness on construction products. It was proven that moisture absorbed by the coatings is retained within this layer and is not transferred to the substrate on which the coatings are laid. It was also found that water in contact with the tested coatings changes its reaction to alkaline, which can result in contamination of groundwater in the area of waterproofing coating. A modification of the method of assessing the water absorption of polymer modified bituminous thick coatings was proposed, taking into account their use in conditions of use.
