    Journal of Ecocriticism 6(1) Spring 2014 Tall-fins and tale-ends in Taiwan: cetacean exploitation, oil refineries, and Moby-Dick1 Iris Ralph (Tamkang University)1 Abstract This article addresses the nineteenth-century novel MoBy-Dick (1851) as a “cetacean text” and as a text that can be taught to question the animal/human Binary that both separates and draws attention to Bonds Between humans and cetaceans. Herman Melville’s novel, Belonging to the period of American literature that F. O. Matthiessen first famously distinguished as the “American Renaissance” in a study so-titled puBlished in 1941, is Being reevaluated today By ecocritics as well as posthumanism and animal studies scholars as a writing that is a cultural record of the North American whaling industry in the eighteenth and nineteenth centuries and raises questions aBout understandings of and assumptions about cetacean slaughter. I tie these concerns to an industry today that threatens cetaceans: the fossil fuel industry, the industry that largely replaced the whaling industry after the twentieth century. I focus mostly on environmental efforts in Taiwan to raise awareness aBout the fossil fuel industry in Taiwan, namely its petrochemical plants or so called naphtha cracker plants and the deleterious impact these plants have on coastal wetland areas that are home to many species of cetaceans including the endangered species of humpBack whale or pink dolphin. Moby-Dick ties to ecocriticism in the eastern regions of the gloBe not the least by reason of the final scenes of the

  • The Decomposition Kinetics of Peracetic Acid and Hydrogen Peroxide in Municipal Wastewaters
    Disinfection Forum No 10, October 2015 The Decomposition Kinetics of Peracetic Acid and Hydrogen Peroxide in Municipal Wastewaters INTRODUCTION Efficient control of microbial populations in municipal wastewater using peracetic acid (PAA) requires an understanding of the PAA decomposition kinetics. This knowledge is critical to ensure the proper dosing of PAA needed to achieve an adequate concentration within the contact time of the disinfection chamber. In addition, the impact of PAA on the environment, post-discharge into the receiving water body, also is dependent upon the longevity of the PAA in the environment, before decomposing to acetic acid, oxygen and water. As a result, the decomposition kinetics of PAA may have a significant impact on aquatic and environmental toxicity. PAA is not manufactured as a pure compound. The solution exists as an equilibrium mixture of PAA, hydrogen peroxide, acetic acid, and water: ↔ + + Acetic Acid Hydrogen Peroxide Peracetic Acid Water PeroxyChem’s VigorOx® WWT II Wastewater Disinfection Technology contains 15% peracetic acid by weight and 23% hydrogen peroxide as delivered. Although hydrogen peroxide is present in the formulation, peracetic acid is considered to be the active component for disinfection1 in wastewater. There have been several published studies investigating the decomposition kinetics of PAA in different water matrices, including municipal wastewater2-7. Yuan7 states that PAA may be consumed in the following three competitive reactions: 1. Spontaneous decomposition 2 CH3CO3H à 2 CH3CO2H + O2 Eq (1) 2. Hydrolysis CH3CO3H + H2O à CH3CO2H + H2O2 Eq (2) 3. Transition metal catalyzed decomposition + CH3CO3H + M à CH3CO2H + O2 + other products Eq (3) At neutral pH’s, both peracetic acid and hydrogen peroxide can be rapidly consumed by these reactions7 (hydrogen peroxide will decompose to water and oxygen via 2H2O2 à 2H2O + O2).
