Methylation levels in tumor-suppressor genes and repetitive sequences have previously been used to study the relationship between environmental air pollution and epigenetic changes related to cancer. In this study, we measured the methylation profiles of the promoter regions CDKN2A, MLH1 and APC and the repetitive sequence LINE-1 in 59 workers exposed to the construction environment and in 49 unexposed workers. We also evaluated the micronuclei frequency and levels of trace elements in the blood of all workers. We evaluated of levels of particulate matter and polycyclic aromatic hydrocarbons (PAHs) at the construction site to characterize the environmental exposure. Our findings demonstrated that exposed workers exhibited significantly higher average levels of promoter methylation of CDKN2A, APC, and MLH1 genes and increased hypomethylation of the LINE-1 in comparison to unexposed workers (all p < 0.05). A higher frequency of micronuclei was observed in the exposed group (2 ± 2) compared to the unexposed group (1 ± 1) with p < 0.001. High levels of particulate matter (51–841 μg/m3) and some PAHs were found in samples from the construction environment. In summary, we provide evidence of increased DNA damage and altered DNA methylation of exposed workers, suggesting that genomic approaches to biomonitoring may be an effective way of estimating future cancer risk for construction workers.

Process Energy

The energy flow process in iron & steel factory is composed of the production, conversion, using of all sorts of energy and waste gas removing. In accordance with the energy flow process, make use of the law of energy conservation and conversion, the energy flow diagram from the energy-consumption analysis, and it is constructed. The energy flow analysis model of iron & steel is designed based on the energy flow diagram. To adopt comparison method, the influence of each process energy-consumption on the energy consumption of iron and steel enterprise also discussed.

Mental Transformations

There are lots of studies conducted in Karabuk province, one of the most important iron-steel manufacturing center in Turkey, and the developing iron-steel sector in this province. However, the privatization of the national iron-steel factory, KARDEMIR, the establishment of Karabuk University and the like, have been causing rapid mental transformations which activate the transformations in iron-steel sector. Especially, the training programs for workers which have been practiced in Karabuk University and The Institute of Iron and Steel founded in Karabuk University indicate that this ongoing transforming process would continue rapidly and favorably. As a result, renewing the studies about the iron-steel sector in Karabuk periodically is a must. In this article, the socio-economic conditions of workers employed in iron-steel sector, their work satisfactions, their visions about iron-steel sector and the like varieties are examined empirically.
