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.

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.
. .

as stated in the article two things have been done to help prevent sewage in overflow systems.one is that, "Nearly 65 overflows already have been permanently closed off, according to the Dept. of Environmental Protection." also, many other communities spent millions of dollars to install grates and shields on the overflow pipes. this would help prevent most trash from entering the system. 

Hazards/risks are distributed among different groups through geography. for example, areas near the Eastern shoreline like places in New Jersey are in a group because their zone damage is much more than those further away from the Eastern shorline like places in Nevada.

Newark helped to set up the JFK Center as a shelter with the help of the American Red Cross. further more, "Booker also urged residents to check on their neighbors, particularly the elderly, to be sure they have adequate supplies and protection during the hurricane"

many recommendations are also being made by the city of Newark to advize their citizens

In this article, It talks mainly about New Jerseys CSO communities and how the CSO's are and have been making steps towards reducing overflow and even though the current solutions being used right now is a way to help reduce the overflow, these systems are also major sources of water pollution. however, CSO's plan to help reduce overflow and help prevent extensive damage from hurricanes will, be beneficial to the public even though it may take a few years for it to be completed and be of use to the public. 

Flood has been and is still a major concern in New jersey because the state is close to or on the 

caost.Whenever an heavy rain falls today , there are flood notifications on everyones phones.

These flood situations lead to traffic,lateness,rise in water levels and all others leading to 

vulnerability in our environment.

The EPA has a large impact to help minimize the hazard. one of the few things that they are doing is provinding the "critical science to develop and implement outdoor air regulations under the Clean Air Act and puts new tools and information in the hands of air quality managers and regulators to protect the air we breathe." also, the EPa designated areas that meet and dont meet the the standards for the PM standards and ozone standards.
