It is time we settled down to a sensible, practical approach to solving the industrial air pollution problem. That is the goal of this paper: to take the sensationalism out and replace it with a sensible evaluation of the situation. The major points covered are 1 a brief review of historical facts, 2 an analysis of present conditions around the world, 3 what is industry’s responsibility, 4 a comparison of legislative procedures and their enforcement effectiveness, 5 the impact of air pollution control costs on worldwide markets, 6 suggestions for solutions.

The World

Economic development in a national and international context must be based on a sustainability strategy established on the systemic interaction between the economic, sociocultural, and ecological environments. Today, the world is confronted by many challenges related to climate change and natural-resource flows, including waste streams resulting from economic activity. The need for national and European environmental standards and the work of an environment monitoring authority to reduce air pollution are highlighted by economic and industrial activities. Thus, our research focused on determining if emissions of sulfur dioxide (SO2), nitrogen (NO2), and particulate matter 10 (PM10) are influenced by planned and unplanned inspections made by competent authorities from Romania. We built a regression model that estimates the influence of economic measures imposed by the authorities on reducing industrial air pollution. Preliminary results showed that the number of inspections negatively influences air pollution, indicating that national and local authorities in Romania are striving to maintain air quality and are conducting more inspections when air pollution is high.

The purpose of this study was to investigate the effects of human gait on air distribution in contagious isolation tent wards. The proposed contagious isolate tent wards were designed as the operating room for serious paroxysmal infectious patients. The three dimensions model of contagious isolation tent ward was reconstructed. Then, the computed fluid dynamical (CFD) methods were used to simulate and analyze the air distribution of contagious isolation tent ward. The dynamical meshes technology was employed to simulate the human gait. An experiment was implemented to measure air velocity of the proposed isolate tent ward. The results showed that the human gait motion affects air pressure, air velocity and contaminant distribution, while the impact on air temperature could be ignored. It was concluded that the impact of human gait or movements should be taken into account in air pollution control of contagious isolation tent wards.

The Impact

PM2.5 pollution-related diseases lead to additional medical expenses and the loss of working hours, thus affecting the macro-economy. To evaluate the health-related economic impacts of PM2.5, the Integrated Assessment Model of Climate, Economic, and Environment (ICEEH), combined with the Computable General Equilibrium (CGE) model, the Greenhouse Gas and Air Pollution Interactions and Synergies (GAINS) model, and a health impact assessment module was constructed. The impact of different air pollution control strategies was analyzed in Guangdong Province by establishing a Without Control (WOC) scenario, an Air Control (AIC) scenario, and a Blue Sky (BLK) scenario. The results show that in the WOC scenario for 2035, the death rate for Guangdong Province is 71,690 persons/year and the loss of working hours is 0.67 h/person/year. In the AIC and BLK scenarios compared with WOC for 2035, the loss of working hours is reduced by 29.8% and 34.3%, and premature deaths are reduced by 33.0% and 37.5%, respectively; GDP would increase by 0.05% and 0.11%, respectively, through strict pollution control policies. Furthermore, improved labor force quality induced by better air conditions would promote the added value in labor-intensive industries, such as agriculture (0.233%), other manufacturing (0.172%), textiles (0.181%), food (0.176%), railways transport (0.137%), and services (0.129%). The added value in the waste (−0.073%), nature gas (−0.076%), and crude oil sectors (−0.072%) would decrease because of the increased investment installment in PM2.5 treatment equipment.

Responsibility System

Whether the environmental target responsibility system, a typical mandatory environmental regulation, can realize the coordinated development of environmental protection and economic growth has attracted widespread attention. With the difference-in-differences (DID) method, this paper utilizes a policy, “China’s Key Cities for Air Pollution Control to Meet the Standards within the Time Limit (APCMS),” as a quasi-natural experiment to empirically examine the target responsibility system of air pollution control’s effect on both firms’ pollutant emissions and their total factor productivity (TFP). The corresponding mechanisms are also investigated. The results show: 1) The policy not only significantly decreases firms’ pollutant emissions, but also improves their TFP. The results are robust to the exclusion of the impact of other policies in the same period, propensity score matching DID (PSM-DID) test, the adoption of alternative dependent variables, and altering sample interval; 2) The dynamic analysis shows that the policy effect on reducing pollutant emissions has increased over years after a lag of 2 years; 3) The policy reduces pollutant emissions mainly through stimulating the internal innovation rather than end-pipe treatment or production cuts. 4) Capital-intensive and private firms and firms in regions with a high degree of marketization or strong environmental law enforcement are found more responsive to the environmental target responsibility system.

Abstract Air pollution control has become the area of interest due to the ever increasing air pollution problem from the automobiles. Several researchers have conducted several experiments to control the air pollution concentration from automobiles by using several techniques but this area has a wide scope for improvement. This research paper is based on an experiment conducted on a Four Stroke Spark Ignition engine test rig using an Innovative catalytic converter which was coated with nano-particles to estimate its effectiveness in air pollution control. The results of the experiment conducted clearly indicate that the Innovative design of catalytic converter is effective in air pollution control from automobiles.
