Urban areas around the world, particularly in emerging nations such as China, India, and Brazil are experiencing high levels of air pollution due to increased population, economy, spending, and consumption, all of which contribute to deterioration in environmental and public health conditions in urban areas. This paper briefly discusses important sources of air pollution, air pollutants of concern, public health impacts, and proposed strategies to combat urban air pollution and promote sustainable urban living. A team of researchers under the mentorship of the main author is working on a number of air quality projects that involve air quality monitoring (sources, ambient, indoor, and occupational), emissions modeling, atmospheric dispersion modeling, air pollution control, and development of knowledge-based systems to manage air quality. This paper presents potential strategies that could help address the growing public health concerns in urban areas and promote sustainable and healthy living.
The transportation of wastewater through sewer networks can cause potential problems due to the formation of lethal gases such as ammonia, carbon dioxide, hydrogen sulphide and methane. As a result, they can cause irritating, toxic, and microbial induced corrosion. The true depth of these problems can be measured by measuring the emission of such lethal gasses in the sewer atmosphere. The amount of gases released from such sewer networks has to be controlled. In this paper, we present a simple experimental methodology used to determine the emissions of Carbon Dioxide (CO2) and Hydrogen Sulphide (H2S) using Landtec GEM-2000 plus multi-gas analyser from wastewater wet wells.
Ports are a major source of economic activity and environmental pollution. They use a variety of equipment for loading/unloading and movement of cargo, such as marine vessels, cranes, trucks and railroads. These activities can cause large amounts of pollution to the air, water and soil media. Despite the pollution generated, it also serves as a medium for tourism with its cruise liners. This paper discusses port activities and how it effects the environment. The main focus of this paper is Knowledge Sharing for Sustainability of Ports. Sustainability indicators should help in evaluating port conditions and this knowledge sharing among the proposed 10 major world ports should accelerate economic growth and use of latest technologies for pollution reduction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
