Analysis of Air Quality in China
&
SARS - CoV - 2 cases
Since long now, air pollution has become a major source of concern and an inevitable issue for every living being in the world’s ecosystem. This type of environmental risk has contributed to 7 million proven and recorded premature deaths yearly. Air pollution is caused by various practices and emissions such as industrial, coal, automobile, and recycling methods. These practices burn fuel, waste and other material which convert into hazardous toxic particles that later merge in the atmosphere.
​
Our responsibility as the inhabitants of this planet, is to take responsibility during times of calamity and to take beneficial steps to mitigate pollution and improve air quality to protect the environment in addition to everyone’s health. Therefore, WHO guidelines recommend the annual mean exposure of the particle to 10 μg/m3.

Statistical Analysis conducted on SAS to observe the Air Quality Trends in the major cities in China; namely Beijing, Shanghai, Shenyang & Guangzhou respectively. Graphical, Tabular and Pictographic representation of the AQI Categories of three Unhealthy groups to better understand the causes, effects and solutions to bad air quality prevailing in China.
This chapter contains various analysis for yearly, monthly & six-hourly bad air prediction using tables, violin & box plots.
Transpose-merging datasets technique on SAS to conduct the Inferential Analysis on AQI and observe the correlation between the Air Quality Trend changes during the SARS CoV - 2 pandemic. A series of differential and dependency tests have been conducted to analyse the relation between Covid 19 cases, deaths and whether other restrictions contributed to cleaner air.
This chapter contains SAS derived Pearson & Spearman correlation, T-tests & Chi-Square tests.
Our tests, analysis and research lead to the derivation of specific conclusions regarding the unanswered questions we faced. Relevant feedback, conclusion and recommendations about the study was presented after analyzing the situation with practical and out of the box solutions. Additional conclusion regarding bad air quality is explained also if Covid 19 had any impact on AQI.
This chapter contains corroborations
Critical Thinking, Logical Explanations & Reasoning with thorough research.
Introduction
China is prominent as the world’s most populated nation with a total of 1,397,897,720 people. The cities used for the analysis are Beijing, Guangzhou, Shanghai, and Shenyang with populations of 11,716,620; 11,071,424; 22,315,474 and 6,255,921 respectively. Due to its population density, China Mainland is also known to be very polluted with high levels of coal production and consumption.
​
This analysis and study are related to the PM2.5 particulate matter (ambient airborne particles) which is responsible for extreme chronic health hazards due to its miniscule size. According to the (WHO) World Health Organization guidelines, the size, and dimensions of this pollutant i.e., 2.5 microns; aids in easy penetration of the particle containing multiple harmful elements and chemical components into the human respiratory system. This particle enters through the nasal cavity and quickly advance into the rest of the blood stream of the body and has the potential to cause adverse acute and chronic long term and short-term disease in humans.

The analysis and study that is conducted on this particular dataset will only consider the AQI Category and AQI values corresponding to “Unhealthy”, “Unhealthy for Sensitive Groups” and “Very Unhealthy” for this study.The tabulated data collected for this report spreads throughout a tenure of seven years starting 2015 until 2021 respectively and the sample comes from four cities of China namely, Beijing, Shanghai, Shenyang, and Guangzhou.
​
According to the World Air Quality report, China Mainland has the greatest number of monitoring stations in addition to the most reach in terms of monitoring network. The total number of monitors managed by the Central Government is around 1,500 and over 5,000 quality check monitors are managed cooperatively by the central, provincial, municipal, and county level government bodies.
