Assessing the PM2.5 impact of biomass combustion in megacity Dhaka, Bangladesh - PubMed (nih.gov)

This article is about crop burning in Dhaka, Bangladesh and attempts to figure out if there is more or less harmful PM2.5 particulate air pollution caused by either fossil fuels or biomass, and during which season is one or the other higher in the air pollution it produces. During monsoon season, fossil fuels lead in the most PM2.5 releases at 44.3%. When it is not monsoon season and is the winter season, the percentages are way higher for PM2.5 air particulate releases at 41.4% for the remainder of the year. Across the globe, there are now people stepping up to uncover the true and real environmental and health impacts this harmful particulate byproduct causes in different parts of the world and with differring weather conditions than what we see in North Carolina. 

Emissions from Biomass Burning in South/Southeast Asia; correcting the miscalculation about the PM2.5 emissions from burning.

This study is set in South/Southeast Asia and uncovering that, when trying to count the percentages of PM2.5 put off during biomass, the true amount of emissions were being gravely undercalculated. Specifically rice straw burning becuase the amount burned varied so much because of different harvest and burning practices that it just wasn't taken into consideration. What this study does is go bottom up using these strategies: "subnational spatial database of rice-harvested area, region-specific fuel-loading factors, region, and burning-practice-specific emission and combustion factors, including literature-derived estimates of straw and stubble burned"(Lasko et al. 2021, 1). 

The Clean Air Act and the EPA laws and regulations against harmful PM2.5 air pollutant matter

The most common air pollutants are called criteria pollutants and are regulated by the Clean Air Act and the EPA. These pollutants are: particles, ozone, nitrogen oxides, sulfer dioxide, carbon monoxide, and lead. The EPA have sections under the CAA that help regulate factories and air pollution in the environment. For example section 108 requires the EPA to identify the pollutants that are criteria pollutants, listed above, and determine if where they are coming from and if they "endander public health or welfare". Under section 109 the EPA had to set standards across the board for air pulltion in regard to human health and to the environemtn sperately (Christopher D. Ahlers 2016, 51-52).  There are many more sections that go into detail about what the CAA can do and what the EPA members are required to do as well.

I used my already existing knowledge of the UN's structure and purpose to further synthesize the role and ability of the UN Special Envoy to Haiti. I also followed up on what sort and amount of aid US AID has been giving to Haiti. From their website, I discovered that they have donated $4.2 billion to date and have assisted in improving legal protections for vulnerable populations. Finally, I followed up on the fact that at press-time, the UN had not admitted responsibility for the cholera outbreak. I found a New York Time article dated 17 AUG 16 that says they had and are making significant new actions toward improving the situation.

MSF is focused on providing aid where aid is needed, thus the name "Doctors without Borders." They don't care what the policital or socioeconomic status is in a region, they'll provide aid no matter what. They're also able to provide their own funding rather than relying upon that of local governments.

I looked into each of the disasters mentioned in the article to find out more about them. I had not heard of the theater fire or boiler explosion before, and found those very interesting.

CEHC offers Undergraduate majors and minors and a Graduate certificate. The major requires 39 credits, or 13 courses, to complete. Students must select a concentration from Emergency Preparedness, Homeland Security, and Cybersecurity. There are 9 core courses and the remaining 4 are in the concentration. The minor requires a student to take 6 classes in the college. The graduate course of study is divided into tracks in which students take courses.
