Kenney purpose: our goal was to identify the cellular and molecular effects of 2-ethylpyridine (2-ep, a component of cigarette smoke) on human retinal pigment epithelial cells (arpe-19) in vitro. Materials and methods: arpe-19 cells were exposed to varying concentrations of 2-ep. Cell viability (cv) was measured by a trypan blue dye exclusion assay. Caspase-3/7 and caspase-9 activities were measured by fluorochrome assays.

4.1. Products and Mechanisms

Glvs undergo reactions with oxidants such as hydroxyl (oh) radicals, nitrate (no3) radicals, ozone (o3), and cl atoms in the atmospheric air. Atkinson and arey [ 167 , 168 ] reviewed the literature on mechanisms and kinetics of gas-phase atmospheric reactions of voc and bvoc but included no data on glv except hexanal and hexenols. Section 4 discusses detailed mechanisms and products of glv reactions with oh, no3, o3, and cl. This review did not aim to cover the theoretical modeling of atmospheric reactions. Interested readers may see an excellent review by vereecken et al. [ 169 ].

As demand increases for an affordable energy source that is tied to an environmental obligation to reduce greenhouse gas emissions and water usage, there is a growing consideration in shale production utilizing processes such as 1) enhancing hydrocarbon recovery via carbon dioxide (co2) flooding, 2) using co2 as a fracturing agent to minimize water use, and 3) storing co2 in depleted shale formations to mitigate emissions to the atmosphere. Understanding the geochemical reactions and alterations that occur as shale is exposed to fluids and co2 is necessary to develop and optimize each of these processes for field applications. While the majority of shale formations are stimulated using traditional fracturing fluid, some may be fractured using co2 or other non-traditional means.

The thermal decomposition results of the four sugar–pam samples are given in figure 3 and the peak temperature of four sugar–pam in the dtg curve are given in table 1. As shown in figure 3 a, two obvious peaks located at 208. 9 °c and 288. 1 °c can be observed with corresponding weight loss of 10. 37% and 33. 59%, respectively. Compared with the original glucose’s dtg, the number of peaks in pure glucose and glu–pam samples are the same, but there is a difference in peak positions. The pure glucose has two peaks located at 215 °c and 275 °c [ 27 ].
