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 will develop a digital presentation of Philadelphia quotidian anthropence and on the theme of climate change adaptation. I will be using this analytic, "Profiling a Climate Policy", which I've created to assess urban adaptation plans. I'll provide more details by next Wednesday April 3rd.

Air polluion involves the introduction of harmful substance into the air.These harmful substances

involves various harmful gases let out by machines, aircrafts and so on.

These pllutions could lead to serious health injuries which could lead to poverty if

too much money is spent in the hospital as treatment could be expensive.

Q1. The report was basically about the how flood has been affecting newark over the past years and the adequate control measures/techniques (laws Movements,permits)

that have been put in place to ensure the prevention of flood in Newark.Agencies that prevent flood have also proven efective and functional over time as in indicated

in the text "Historically, New Jersey has taken a strong role in the development of a rigorous floodplain management program at the State level while supporting those

same efforts at the Federal level with the Federal Emergency Management Agency (FEMA) "(Floodplain Mapping Unit paragraph 1).This report would make resident feel

at ease knowing the problem of flooding is uder control.

Reacting to this report, Although Its is very reassuring knowing all these Agencies,funding,laws, and concerns are in place, I believe extra effort should be put in not only

in Newark but also in other flood affected areas in New Jersey and The United States as a whole because water levels are rising (major concern in coastal areas)and new methods should be put in place to

avoid major casualties.
