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. 

The policy is that developers request environmental permits to inform the city of any environmental problems. The aim is to achieve sustainability and a safe environmental life for citizens. 

The product used to measure the level is a portable air sensor; This product is an innovative development because as it says in the article Molly Greenberg allows to obtain air quality data, this is clearly a breakthrough since years ago getting this information was not possible or the process was much more complicated.

I think it is an important step, clearly for presenting complaints, the problem will not be solved; we should all do it if we see something of this kind. In addition to the complaints, there are many steps to follow, such as organizing protests, taking care of daily consumption or becoming aware that a sustainable life is better for everyone.

The participation of the EPA in the improvement of air pollution in Newark has a great relevance because it is an organization that has the ability to invest money in technologies that allow to have a greater knowledge of the levels of air pollution. This allows you to prevent problems and have more information to fight them better.

I think that if it is possible to reconcile both developments, since both are necessary for social development we should look for policies that help to live with both. If a sustainable use of the industry is made, it can offer favorable living conditions and at the same time not harm the environment.
