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.

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 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. 

In my opinion, something that is ethically wrong with this case is the fact that much of the pollution coming from biomass factories like Enviva are disproportionately affecting Black and Brown rural comminities. These communities experience health issues from the saw dust and can be seen cleaning sawdust off their outside belongings. It is important to see how much thes communities are impacted when looking at biomass corporations.

The complaints of Duplin County residents and the Environmental Justice Community Action Network about general permitting for hog farms in Eastern NC. These permits would give way to more ground and water pollution due to the relaxed regulations on corporate farms that hold multiple different numbers of livestock. Plans for the implementationa pipline called the "Grady Road project" interrupt the family and small scale farms in the ares. A quote from the Duplin County NAACP president Robert O. Moore says:

"The corporation has refused to implement any technology to clean up the water, citing the cost of doing so was too expensive. Yet the cost of this biogas project rivals the cost that would have been to implement cleaner and safer technology to ensure the safety of those living near these operations."

Many local groups in Eastern NC counties have previously tried to receive assistance to help with their agriculture waste managment systems, yet fall short due to many government officials only focusing on corporate farms.
