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.

The presented artifact talks about the pollution management in the Passaic River. The water body has been contaminated from previous manufacaturing companies that would dump toxic material into the river. According to the Environmental Protection Agency, "two cleanups of the river have been completed." However, the plan on a third cleanup was created in March of 2016. The state is looking into getting residents back to the river through park creation, education and cultural events which I find great, but a concern of mine is what if the water isn't safe enough? These things have to be taken into consideration because human lives are at stake.

I uploaded this artifact because I believe that reparing Newark’s infrastructure is very important, especially since a lot of it’s economy relies on it. Without the repairs, it would lead to bigger problems such as increasing the cost of maintenance for its residents and the companies that use it daily. This decision made me realize that although Newark is struggling in bringing its economy back, its politicians know that maintaining it’s road is the foundation towards recovering from the recession.

This article presents how Newark is taking precautionary measures to help people affected by incoming Hurricane Sandy.  The city of Newark opened JFK Center as a shelter with the help of the Amercian Red Cross. The city also advised business and home owners how to prepare for the storm to avoid minimal damage to their properties. This display of precaution demonstrates how Newark is resilient to incoming storms during hurricane seasons.

This article brings Newark’s water contamination problem up, specifically the amount of lead found in recent studies. Newark’s water was found to have three times the amount of acceptable lead in its tap water, but no specific locations were give as to what places are being affected by this contamination. Newarks Water Department will be required to take actions such as testing public school water supplies, changing lead pipe lines, and maintaining more accurate maintainence schedules and records. By holding people accountable, Newark is changing its vulnerability towards water contamination
