DNA adducts derived from complex mixtures of polycyclic aromatic compounds emitted from tobacco smoke are compared to industrial pollution sources (e.g., coke ovens and aluminum smelters), smoky coal burning, and urban air pollution. Exposures to coke oven emissions and smoky coal, both potent rodent skin tumor initiators and lung carcinogens in humans, result in high levels of DNA adducts comp...

10 The development of hypersonic vehicles (up to Mach 10) leads to an important 11 heating of the whole structure. The fuel is thus used as a coolant. It presents an endothermic 12 decomposition with possible coke formation. Its additional permeation through the porous 13 structure involves internal convection. This implies very complex phenomena (heat and mass 14 transfers with chemistry). In ...

Green petroleum coke is primarily inorganic carbon with some entrained volatile hydrocarbon material. As part of the petroleum industry response to the high production volume challenge program, the potential for reproductive effects was assessed in a subchronic toxicity/reproductive toxicity screening test in rats (OECD 421). The repeated-dose portion of the study provided evidence for dust acc...

OBJECTIVE Increased consumption of sugar-sweetened beverages has contributed to rising obesity levels. Under Canadian law, calories for pre-packaged foods and beverages are presented by serving size; however, serving sizes differ across products and even for the same product in different containers. This study examined consumer understanding of calorie amounts for government nutrition labels an...

AIM Using scanning electron and light microscopy, this study qualitatively evaluated the erosive potential of carbonated cola beverages as well as sports and high-energy drinks on enamel surface substrate. METHODS AND MATERIALS Beverages used in this study included: Coca Cola Classic, Diet Coke, Gatorade sports drink, Red Bull high-energy drink, and tap water (control). Extracted human perman...

OBJECTIVES In 2011 recommendations for the prescription of lung cancer in coke oven workers were made in the UK. In the 1970s, a powered helmet respirator, the Airstream helmet, was introduced to the UK coking industry with the aim of reducing exposure to polycyclic aromatic hydrocarbons (PAH) aerosols and consequent lung cancer risks for workers on the coke oven tops. This review set out to id...

Background: Coke oven workers are regularly exposed to coke oven emissions (COE) and may be at risk of developing lung diseases. There is limited evidence for the link between exposure to COE and chronic obstructive pulmonary diseases (COPD). The aim of this study was to explore the dose-response relationship between COE exposure and COPD and to assess the interaction with cigarette smoking. Me...

So carried away was I in my last book review by a cadre of his book on its that I and his beat in the Aegean with his materials Handbook, a concise and desktop reference also although not so captivating as the earlier book, no doubt because it lends itself is readily to a sitting duck missions, that he has handled issues for an error but completion. Balls of it consists of separate chapters on ...

Electric arc furnace (EAF) dust, together with a mill scale and coke were smelted in a laboratory electric arc furnace. These metallurgical wastes consist of a many different phases and elements, making the reaction process complex. Thermo-chemical analysis of the reactions in metal, slag, and gas phases was done, and used for modeling of the mixture composition and energy consumption required ...
