Air Pollution

Reduce Carbon footprint in Rawalpindi Pakistan (Published)

In developing countries such as Pakistan, atmospheric pollution has become a disaster. This study’s objective was to observe and evaluate the air quality in the 15-million-person combined population of the twin cities of Rawalpindi and Islamabad in Pakistan. The quantities of particulate pollution, as well as CO2, were measured in five different cities. There are now far too many types and sources of pollution from numerous air pollutants. However, due to an absence of management skills for air pollution, the world is currently facing diminishing air quality. The ecosystem, public health, and quality of life are all seriously threatened by air pollution, according to facts from multiple governmental organizations and foreign organizations. Through the Pakistan Environmental Protection Program, the Pakistani government has implemented important strides toward air quality management, including the establishment of few active monitoring stations. However, there are currently no standards for environmental protection. This paper examines the standards for air pollutants from observational studies. Five main air pollutants—NO2, SO2, CO, O3, and PM2—were taken into consideration. Our findings show that under the baseline scenario, Existing air pollution in Pakistan management efforts are inadequate to achieve the nation’s air quality criteria. By 2050, the percentage of deaths caused by PM2.5 will be 24% lower nationwide because of the implementation of sustainable development policies. Innovative standard precautions can improve Pakistan’s air quality and public health, but when associated with foreign long-term new developments, they can also lower greenhouse gas emissions (implementing SDG 13’s indicator on climate action) and save about a quarter of GDP (0.32% of GDP) on costs associated with emission control by 2050. It seems to have a substantial co-benefit in terms of cost (economic), health (social), and air pollution (environmental), suggesting that Pakistani public policy should consider a co-control at a low cost of greenhouse gases and air pollution in the future.

Community Perception on Air Pollution and Public Health: A Case of Ewekoro And Remo-North Communities in Ogun State, Nigeria (Published)

Air pollution has become an issue of concern in Nigeria with its consequent effects on human health. Hence, this study is an empirical investigation on community perception on the effect of air pollution on public health in Ogun State, Nigeria. The study was conducted in Ewekoro and Remo-North local government areas in Ogun State. The focus study area was Ewekoro as a result of the activities of LAFARGE Cement factory in the community. Primary data were used for the study. A total of 200 structured questionnaires were distributed to respondents through systematic random sampling techniques to elicit information on air pollution and health. Both descriptive and inferential statistics were used for the analysis. Results from the study show that the people are fully aware of air pollution, and there is prevalence of air pollution in Ewekoro which is largely caused by the activities of LAFARGE Cement. The findings show that air pollution has a significant negative effect on public health. Also, health risk associated with air pollution has a significant negative relationship with public health.

Spatio-Temporal Analysis of Atmospheric Pollutant Concentrations at Bus Terminals along Major Traffic Corridors in Port Harcourt Urban Areas (Published)

This study empirically analyzed atmospheric pollutants concentration especially its relationship to meteorological parameters in the vicinity of bus terminals in the city of Port Harcourt. Data on both atmospheric pollutants ((PM₁, PM_2.5, PM₇, TSP, SO₂, NO₂, CO, VOC and CO) with their meteorological variables were collected with the aid of Aeroqual 300 series multi-Gas Meter and Extech weather station Gavin UID respectively; in Mile 1, Mile 3, Garrison, Rumuola and Lagos park bus terminals which were selected based on their high level of socio-economic activities and high frequency of buses alighting. Data were analysed using the Pearson’s Product Moment Correlation Coefficient, Step-Wise Multiple Regression and Analysis of Variance (ANOVA). Findings indicates that that Relative humidity (RH) had a direct relationship but low correlation with PM₁ PM₇, TSP and CO of correlation values (r) of 0.343, 0.229, 0.271 and 0.146 respectively but inversely correlated with SO₂ (r = -0.476). However, RH had a direct significant relationship with PM_2.5, SO₂, and VOC (r = 0.548, 0.629 and 0.595 respectively at p = 0.05). Temperature had a significant but inverse relationship with PM_2.5, SO₂, and VOC (r = -0.524, -0.641 and -0.6 12 at p = 0.05) and a direct significant relationship with NO₂ (r = 0.712) and CO₂ (r = 0.553.  Wind speed  showed a weak relationship with PM₁ and CO₂  (r = 0.010 and 0.205 ) but inversely and significantly correlated to PM₇, PM₁₀, TSP, CO, PM_2.5, SO₂ and VOC (r = -0.398, -0.398,  -0.436, -432, -0.575, -0.864 and  respectively) which means that as wind speed reduces the concentration of these pollutants increases at the bus terminals. Result showed that there were elevated spatial and temporal concentrations of these pollutants because of calm atmospheric condition prevailing at the bus terminal. Enforcement of stricter laws and regulations to control emissions of these obnoxious air pollutants because of their health implications for commuters is strongly recommended.

Air Pollution: A Threat to the Efficiency of Porous Pavements (Published)

Over the years the world has been detecting and monitoring the increase in surface temperature. The vast majority of scientists have named it the phenomenon of global warming resulting in climate change. The Metropolitan Region of the State of Rio de Janeiro, in recent years, accompanied the increase in air pollution by the transport sector and concluded that the sector contributes to these climatic phenomena in local and global levels. Many strategies have been developed to minimize the impacts of this and other sources of emissions to the environment. New research and technological advances must be deployed immediately to try to mitigate the adverse effects of climate on Earth and prevent natural disasters, such as happens quite often nowadays. This study draws attention to another type of pollution, extremely dependent on air pollution: impacts of the use and occupation. Nevertheless, it highlights the importance of monitoring the temperature of the earth’s crust, to confirm that surface temperatures and below increased proportionately. The porous pavements, even in small patches, are important to contribute to the balance of the ecosystem but the quality of air we breathe is both harmful to health on the ground that receives it. So educate the public about the harmful effects of air pollution unimaginable is the bottleneck for the replacement of traditional waterproof decks for porous pavements and as a consequence, facilitate the exchange liquid and gas, so necessary in the process of cleaning up and slowing global warming.
