“…Socioeconomic data of the 31 PCCs was retrieved from the Chinese cities year book (the data collected in the administrative area of the city, which includes the urban, surrounding suburban and rural areas) (http://www.stats.gov.cn) and official municipal websites. According to previous studies, urban size, residents' activities, industrial activities and urban greening are the four socioeconomic factors which impacted the variation of AV [9][10][11][12][13][25][26][27][28][29][30][31][32][33][34][35][36][37]. For our study, we used the four variations previously mentioned and selected indicators for each socioeconomic variable by following two criteria.…”

Millions of pulmonary diseases, respiratory diseases, and premature deaths are caused by poor ambient air quality in developing countries, especially in China. A proven indicator of ambient air quality, atmospheric visibility (AV), has displayed continuous decline in China’s urban areas. A better understanding of the characteristics and the factors affecting AV can help the public and policy makers manage their life and work. In this study, long-term AV trends (from 1957–2016, excluding 1965–1972) and spatial characteristics of 31 provincial capital cities (PCCs) of China (excluding Taipei, Hong Kong, and Macau) were investigated. Seasonal and annual mean values of AV, percentage of ‘good’ (≥20 km) and ‘bad’ AV (<10 km), cumulative percentiles and the correlation between AV, socioeconomic factors, air pollutants and meteorological factors were analyzed in this study. Results showed that annual mean AV of the 31 PCCs in China were 14.30 km, with a declining rate of −1.07 km/decade. The AV of the 31 PCCs declined dramatically between 1973–1986, then plateaued between 1987–2006, and rebounded slightly after 2007. Correlation analysis showed that impact factors (e.g., urban size, industrial activities, residents’ activities, urban greening, air quality, and meteorological factors) contributed to the variation of AV. We also reveal that residents’ activities are the primary direct socioeconomic factors on AV. This study hopes to help the public fully understand the characteristics of AV and make recommendations about improving the air environment in China’s urban areas.

“…In the border region, industries are accountable for 17% of sulfur dioxide, 5% of nitrogen oxides, 3% of hydrocarbons, and a large quantity of particulate matter (specifically PM 10 ) (Blackman et al 2004). These pollutants, among others, are linked to severe health effects, such as asthma, obstructive pulmonary diseases, decreased lung function, exacerbation of Type 2 diabetes, and cancer (Quintana et al 2018). In other border cities, like Ciudad Juárez in Mexico, these health damages are up to 50 times higher than in areas in the U.S. without maquiladoras nearby, and are 10 times higher than the U.S. sister city of El Paso, Texas.…”

“…70,000 northbound vehicles and 20,000 pedestrians cross on average each day (U.S. General Services Administration, n.d.). In 2013, this added up to 11.3 million cars and 7.6 million pedestrians crossing (Quintana et al 2018). Trucks transporting input materials and exports from maquiladoras and other commercial vehicles cross at the Otay Mesa POE, located about 10 miles away from the San Ysidro POE.…”

“…This is only aggravated if these people are daily commuters and are exposed to nearby idling vehicles on an extremely frequent basis. Exposure inside vehicles can be up to 50% of a person's daily exposure to PM (Quintana et al 2018). Quintana et al (2018) conducted a study that measured this in-vehicle exposure while crossing the San Ysidro POE in comparison to levels in Tijuana and San Diego, specifically studying the levels of black carbon (BC), carbon monoxide (CO), and ultrafine particulate matter (UFPs, PM<100 nm).…”

Environmental Health and Policy at the Tijuana-San Diego Border

Immigration at the U.S.-Mexico border, walls and security, and drug trafficking, are among the most deliberated policy issues in the U.S.'s political climate. As a result, policies and international cooperation concerning environmental health impacts at the border are often overlooked, particularly in the Tijuana-San Diego border region. These impacts include contamination and overuse of water by maquiladoras, air pollution from concentrated border transit and power plants, and the heightening threat of global warming. However, as climate change worsens and immigration problems grow, this wide range of environmental hazards demand ambitious policy considerations, especially in the Tijuana-San Diego border region. In this project, I analyze environmental health and environmental justice at the Tijuana-San Diego border. I specifically focus on air and water quality and their subsequent health impacts for populations in this region. These populations include permanent residents on both sides of the border, commuters, and groups of migrants forced to stay in temporary camps awaiting asylum processes. I provide an analysis of air and water pollution and the extent to which they cause health problems, as well as how these uniquely affect an increased concentration of migrants during the Trump era. My thesis offers insight on areas for policy improvement and cross-border solutions that encourage and maintain an environmentally just region for all populations.

The system design includes a large data analysis model design and system software for automatic monitoring of vehicle pollutant discharge. In that method, a quantitative statistical analysis method is adopt to carry out cloud computing fusion processing of automatic monitoring of pollutant discharge of a motor vehicle, and the invention relates to an information fusion and recombination model for automatically monitoring large data of pollutant discharge of a motor vehicle, the method of automatic monitoring of vehicle pollutant discharge based on the fusion algorithm is improved by the effective feature of the automatic monitoring of the pollutant discharge of the motor vehicle. In the development of B/S and embedded PCI bus, the software development and design of the automatic monitoring system for pollutant discharge of motor vehicle are carried out, and the hardware structure and software development of the automatic monitoring system for pollutant discharge of motor vehicle are carried out. The results of the test show that the automatic monitoring system for motor vehicle pollutant discharge is good in stability and strong in the sampling and statistical analysis of the physical information.
