“…The possible exposure to benzene in coke oven workers has been reported in previous studies. Dehghani and co-workers determined the levels of benzene, toluene, xylene, and ethylbenzene in the breathing zone air of workers through individual sampling in the coke-making unit of a steel plant and found that benzene levels were higher than the local exposure limits [20]. In another study, toluene and benzene were among the highest VOCs present in the workplace air of the coke-making process; however, the authors evidenced that the concentrations of workplace air pollutants were lower than their local hazardous air pollutant standards for workplace air [25].…”

“…Moreover, coke oven workers might also be exposed to VOCs emitted during destructive distillation. Indeed, a certain number of studies assessed the exposure to VOCs in coke oven workers quantifying their levels in workplace and breathing zone air, with overall levels ranging from 22.6 µg/m 3 to 2.17 mg/m 3 [20][21][22][23][24][25][26][27][28]. Only a few studies performed biomonitoring of VOC metabolites in coke oven workers.…”

Coke production was classified as carcinogenic to humans by the International Agency for Research on Cancer. Besides polycyclic aromatic hydrocarbons, coke oven workers may be exposed to benzene and other volatile organic compounds (VOCs). The aim of this study was to assess the exposure to several VOCs in 49 coke oven workers and 49 individuals living in the same area by determining urinary mercapturic acids. Active tobacco smoking was an exclusion criterion for both groups. Mercapturic acids were investigated by a validated isotopic dilution LC-MS/MS method. Linear models were built to correct for different confounding variables. Urinary levels of N-acetyl-S-phenyl-L-cysteine (SPMA) (metabolite of benzene), N-acetyl-S-(2-hydroxy-1/2-phenylethyl)-L-cysteine (PHEMA) (metabolite of styrene), N-acetyl-S-(2-cyanoethyl)-L-cysteine (CEMA) (metabolite of acrylonitrile), N-acetyl-S-[1-(hydroxymethyl)-2-propen-1-yl)-L-cysteine and N-acetyl-S-(2-hydroxy-3-buten-1-yl)-L-cysteine (MHBMA) (metabolites of 1,3-butadiene) were 2–10 fold higher in workers than in controls (p < 0.05). For SPMA, in particular, median levels were 0.02 and 0.31 µg/g creatinine in workers and controls, respectively. Among workers, coke makers were more exposed to PHEMA and SPMA than foremen and engine operators. The comparison with biological limit values shows that the exposure of workers was within 20% of the limit values for all biomarkers, moreover three subjects exceeded the restrictive occupational limit value recently proposed by the European Chemicals Agency (ECHA) for SPMA.

“…[36], supported this by stating that damages caused to houses by external forces include damages to doors, windows, roofs and other parts of building due to strong winds and erosion that threatens building foundation which are mostly triggered by illicit digging of boreholes and water wells in residential areas. [37] also stated that poor waste disposal near houses and homes makes occupants prone to diseases and rodents attacks. Similarly, the results presented in Table 3 reveals the possible ways of mitigating the threats posed by the environmental factors on buildings.…”

The effects of environmental factors on buildings have become a major issue in recent times as it causes worry and discomfort for building occupants. Some of the threats of environmental factors to buildings include: dust, smoke, acidic rain, flood, loss of life and properties, building failure and collapse. As a result of this, the cost of building construction and maintenance is increasing at an alarming rate and that is why this research aims to identify the ways of reducing the threats of environmental factors to buildings especially in Nsukka Urban area of Enugu State, Nigeria. The research aims at analyzing the threat of environmental factors to buildings, and proffer remedial measures to these effects.. The instrument used for the data collection was structured questionnaire and the target population consisted of groups of professionals who were architects, builders, quantity surveyors, engineers and some residents in Nsukka. Analysis of the data was done using the mean item scores. The study revealed that interface with the ecosystem, increase in various types of pollution and deforestation are major environmental threats to buildings. The study identified ways of reducing the threat of environmental factors to buildings some of which includes the use of energy-efficient and eco-friendly equipment for building construction, planting trees and shrubs as wind breakers near the houses and homes to reduce the speed of wind. The study recommends the need to adopt and implement sustainable construction practices as a way of reducing the environmental threats to buildings. This can be achieved if all the stakeholders are involved, especially the government, which plays a cardinal role in the formulation of regulations and policies that support sustainable construction practices. Keywords: Buildings, Environmental Factors, Threats of Environmental Factors and Nsukka Urban

Acrylonitrile is a potential carcinogen for humans, and exposure to this substance can cause adverse effects for workers. This study aimed to carcinogenic and health risk assessment of acrylonitrile vapor exposure in exposed personnel of a petrochemical complex. This crosssectional study was performed in 2019 in a petrochemical complex. In this study, to sample and determine acrylonitrile’s respiratory exposure, the method provided by the National Institute of Occupational Safety and Health (NIOSH 1601) was used, and a total of 45 inhaled air samples were sampled from men workers, aged 39.43 ± 9.37 years. All subjects’ mean exposure to acrylonitrile vapors was 71.1 ± 122.8 μg/m 3 . Also, the mean exposure index among all subjects was 0.02 ± 0.034. The non-carcinogenic risk assessment results showed that the mean Hazard quotient index was 4.04 ± 6.93. The mean lifetime cancer risk index was also 2.1 × 10 -3 ± 3.5 × 10 -3 and was in the definite risk range. Considering that both carcinogenicity and health indicators of exposure to acrylonitrile in the studied petrochemical complex are more than the recommended limits, the necessary engineering and management measures to control and manage the risk to an acceptable level are essential to improving the worker’s health.
