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 author is Sonja D. Schmid who is a professor of Science and Technology in Society at Virginia Tech. Her area of expertise is the social aspect of science and technology, esp. during the Cold War, as well as science and technology policy, science and democracy, qualitative studies of risk, energy policy, and nuclear emergency response. As a professor and researcher she has does relevant studies on Fukushima and nuclear disasters relevant to the DSTS network. One such article titled "The unbearable ambiguity of knowing: making sense of Fukushima" is cited below:

This policy directly affects first responders and technical professionals as they will be the ones interacting with patients and following the protocols outlined in this plan. First responders are required to recognize and report suspected ebola incidents, use appropriate PPE, and transport to appropriate facilities if feasible.

Vulnerability and resilience in this artifact are defined by the high concentration of child poverty in Essex County. They are measured using the Census from 2000 and 2015 which show how there is a trend in the percentage of children who expereince poverty within the county. Majority of the children living in poverty are currently living in heavilyu concentrated poverty neighborhoods like Newark, Irvington, and the Oranges. Although the affluent town of Milburn is nearby, it is unclear how these children continue to live below the poverty line in Newark even though the towns are only 6 miles apart.

This is supported by analyzing the current emergency response system for nuclear disasters. Schmid notes that disaster prevention was the focus of the nuclear industry and disasters were rare up until recent and emergency response was hardly focused on. She also notes that as the nuclear sectors grows in size the frequency of disasters will likely increase and there has been a noticeable shift in focus towards emergency response.
