For ethylene produced from naphtha and ethane, the energy expended during the extraction and ocean-based transportation of fossil fuel sources (crude oil and natural gas) contributes significantly to adverse environmental impacts such as GHG emissions, acidification, and eco-toxicity (air and water).

In the second level EHS assessment, the parent amine heavily influences most mass dependent hazard categories such as the fire/explosion, acute toxicity and air mediated effects category.
Hence, we concluded that the occurrence of dramatic MS alterations in 3p chromosome multiple critical regions could be a crucial underlying mechanism, which proceeded the lung toxicity in air pollution PM-exposed target L132 cells.
Enhanced susceptibility to the toxicity of air pollutants may include individuals with metabolic syndrome (MetS).
A549 cells are a model of respiratory epithelial cells with some type II-like cell characteristics that have been extensively used to assess the toxicity of air pollutants.
Whereas DT-diaphorase is associated with increased toxicity in air, it appears to reduce the cytotoxicity of EO9 in hypoxic conditions.
With the exception of CO which is known to cross the placental barrier and bind efficiently with fetal hemoglobin, the mechanism of toxicity of air pollution on the fetus is poorly understood [ 25, 26].
Previous in vitro studies have utilized these chambers to expose individual cell cultures to examine the toxicity of air pollution mixtures and have shown that exposure to photochemically altered particle-free urban mixtures causes significant inflammatory responses (Sexton et al. 2004) and greater genetic alterations (Rager et al. 2011) compared with exposure to primary urban mixtures.
