Mercury and its derivatives are hazardous environmental pollutants and could affect the aquatic ecosystems and human health by biomagnification. Lake sediments can provide important historical information regarding changes in pollution levels and thus trace anthropogenic or natural influences. This research investigates the 100-year history of mercury (Hg) deposition in sediments from Chao Lake, a shallow eutrophic lake in China. The results indicate that the Hg deposition history can be separated into three stages (pre-1960s, 1960s–1980s, and post-1980s) over the last 100 years. Before the 1960s, Hg concentrations in the sediment cores varied little and had no spatial difference. Since the …
Evaluating The Impact Of Fine Particulate Matter Pollution Standards On Mortality Rates In The Southeastern United States, Lauren Wice
MPA/MPP/MPFM Capstone Projects
The Environmental Protection Agency (EPA) continuously monitors six criteria pollutants that are known to have impacts on public health and welfare. One of these pollutants, fine particulate matter, or PM2.5 (which includes particles that are smaller than 2.5 micrometers in diameter), is easily inhalable and can enter the lining of the lungs and the bloodstream, posing a great risk to human health. Standards for allowable concentrations of PM2.5 were amended in 1997, 2006, and again in 2012, becoming increasingly stringent each time. According to the EPA, health organizations, and other research studies, these particles can specifically contribute to …
Does The Emission Trading System Reduce Greenhouse Gas Emissions & Coal Consumption And Lead To An Increase In Renewable Energy? – Evidence From Oecd Member Countries, Pilmu Ryu
MPA/MPP/MPFM Capstone Projects
The Emission Trading System (ETS) on greenhouse gas (GHG) is a climate change policy well-known as a market-based mitigation mechanism. However, policymakers have faced strong opposition of many stakeholders and failed to persuade them in the process to introduce the ETS. Objective evidence on ETS impact not only provides information to policymakers but also may help alleviate controversy between stakeholders and policymakers. Also, empirical results on ETS will be able to contribute to the theoretical economic study of cap-and-trade. In this context, this research aims at empirical analyses of ETS impact with regard to GHG emissions, coal consumption, and renewable …
