Comprehensive review on risk assessment methodologies for HAZMAT transportation between 1995-2015

Issue related to safety, health and environmental has become major priority to be concerned of in the transportation of hazardous materials (HAZMAT) worldwide. Due to the high risk that entailed in the operation of HAZMAT transportation, many accidents in this industry have been reported which include chemicals spillage, fire and explosion. In order to quantify the degree of hazards and risks of these accidents, various assessment methods have been introduced either by the academia, the industry as well as the authority. The methods present various approaches for the assessment, ranging from a simple to highly complicated ones depending on the purpose of the assessment and the available resources and constraints. To date there is yet any study conducted to review those available methods. This paper intends to present a comprehensive review of the existing methods for hazards and risks assessment of HAZMAT transportation between years 1995-2015 which considers road, marine, railway, air and pipeline system. Based on careful screening of the abundance of methods available, 151 of them were selected – that is those specifically meant for hazards and risks assessment of HAZMAT transportation only. The methods are reviewed in terms of the types of assessment; either qualitative, quantitative or hybrid techniques, as well as their specific application in different mode of transportation. Also, statistical analysis was performed to determine the trend of past publications regarding on the type of journal, year of publication and also financial support received in the context of hazard and risk assessment of HAZMAT transportation

Energy End-Use Technologies for the 21st Century. A Report of the World Energy Council

This report makes clear the opportunities and places technology development firmly centre stage in meeting and overcoming the challenges confronting the energy industry and policy makers. Energy End-Use Technologies for the 21st Century makes it crystal clear that technologies deployed in 20 to 50 years will be the result of policy and funding decisions taken now and that we cannot afford to duck these decisions if we are to meet the World Energy Council’s goals of energy availability, accessibility and acceptability

Evaluating the Microbial Quality and Use of Antimicrobials in Raw Pet Foods

Raw meat-based diets (RMBDs) are emerging pet foods that pose food safety risks because of the potential presence of pathogens that could cause illness to humans. In this research, the microbial quality of select RMBD products sold by pet food companies online and the use of chemical antimicrobials to reduce the microbial load in chicken liver, a common RMBD ingredient, were evaluated. Ground meat blends and livers from four animal species (beef, pork, chicken, turkey) were purchased from four online companies that delivers directly to consumers through parcel businesses. Products were procured at three different times during one year and were assessed for their microbial quality, specifically aerobic plate count (APC), lactic acid bacteria (LAB), yeast and molds (Y&M), Enterobacteriaceae (EB), Salmonella spp., Escherichia coli, and Listeria spp. Overall, the microbial quality of the products were poor with some having high levels of indicator microorganisms that exceed acceptable levels of hygienic food criteria, e.g., APC (3.1 %; 2 out of 65) and EB (21.5 %; 14 out of 65). Presumptive Salmonella, generic E. coli and Listeria colonies were also detected in 33.8, 96.9, and 98.5 % of the samples, respectively. All four B2C companies missed at least one required information on their product labels, as well as safe food handling and storage instructions. The effect of immersing and agitating chicken livers in peracetic acid (PAA, 450 ppm), cultured dextrose fermentate (CDF, 1.5 % w/v) and buffered vinegar (BV, 1 % w/v) on the reduction of Salmonella spp. and aerobic bacteria and meat color was investigated. All treatments [including distilled water (control)] resulted in significant reductions in Salmonella counts (p \u3c 0.05). PAA resulted in the highest numerical Salmonella reduction from Day 0 (0.65 ± 0.12 log) to Day 14 (1.31 ± 0.12 log), although there were no significant differences in log reductions compared to control, signaling that immersion and agitation alone can reduce Salmonella. BV was the most promising in inhibiting the growth of aerobic bacteria – BV inhibited growth to Day 7, while PAA and CDF inhibited growth until Day 3 only. Advisors: Mary-Grace Danao & Byron Chave

Vulnérabilité du territoire: caractérisation et implémentation en gestion de crise

International audienceCe chapitre a pour objectif de présenter les éléments recueillis et analysés pour évaluer la vulnérabilité du territoire s'étendant de Nice à Savona face au risque d'accident de TMD et des conséquences associées. Une définition de la vulnérabilité territoriale est proposée à partir d'une analyse de modèles et d'indice de vulnérabilité. Le premier point s'attache ainsi à définir le concept de vulnérabilité. Le deuxième point aborde les différents seuils de vulnérabilité biophysique caractéristiques des enjeux humains et des structures recueillis auprès d'organismes et centres de recherche nationaux et internationaux réalisant des études toxicologiques et de résistance des matériaux. Le troisième point décrit le territoire d'étude, les flux de marchandises dangereuses qui le traversent sur ses axes routiers et présente les éléments considérés comme vulnérables face aux conséquences d'accidents de TMD à proximités des voies d'accès. Enfin, la dernière partie propose une définition de la vulnérabilité territoriale face au risque de TMD sur laquelle s'appuie le modèle général de réduction de la vulnérabilité proposé et qui sous-tend les travaux de recherche et développement présentés dans les chapitres successifs

Environmental Emissions

Today, the issue of environmental emissions is more important than ever before. Air pollution with particulates, soot, carbon, aerosols, heavy metals, and so on is causing adverse effects on human health as well as the environment. This book presents new research and findings related to environmental emissions, pollution, and future sustainability. Written by experts in the field, chapters cover such topics as health effects, emission monitoring and mitigation, and emission composition and measurement
