Air quality research is a topic of increasing importance as the negative impacts of air pollution on human health and the environment continue to be recognized. There are a variety of research topics within the field of air quality that are worthy of exploration. Some potential air quality research topics include:
The impacts of air pollution on human health: Air pollution has been linked to a wide range of negative health outcomes, including respiratory and cardiovascular disease, cancer, and premature death. Researchers can study the specific health impacts of different pollutants, as well as the ways in which air pollution may disproportionately affect certain populations, such as children, elderly individuals, and those with preexisting health conditions.
The sources of air pollution: Identifying the sources of air pollution is a critical step in developing strategies for reducing it. Researchers can study the various sources of air pollution, including industrial facilities, transportation, and natural sources such as wildfires, to understand their relative contributions to air pollution and the ways in which they can be mitigated.
The development of cleaner technologies: Researchers can work on developing technologies and practices that can reduce air pollution. This can include the development of cleaner fuels, more efficient industrial processes, and advanced transportation technologies, such as electric vehicles.
The effectiveness of policies and regulations: Researchers can study the impact of policies and regulations aimed at reducing air pollution, including the effectiveness of different approaches, such as emissions standards, economic incentives, and education and outreach efforts.
The impacts of air pollution on the environment: Air pollution can have significant impacts on the environment, including damage to forests, crops, and bodies of water. Researchers can study these impacts and the ways in which they can be mitigated.
Overall, the field of air quality research offers a wealth of opportunities for studying the impacts of air pollution and developing strategies for reducing it. Through this research, we can better understand the causes and consequences of air pollution and take steps to protect human health and the environment.
Air Quality
Assessment Pre-Lesson Assessment Vocabulary List: Have students look over the Post-Introduction Assessment Post-Lecture Quiz: Immediately after the slide presentation lecture, administer the five-question Pre-Unit STEM Survey: After students complete this lesson and its first associated activity, administer the six-question STEM Survey 2. In addition to human and environmental health, many pollutants that we worry about are greenhouse gases and contribute to climate change. Alignment agreement: Thanks for your feedback! Educational Standards Each TeachEngineering lesson or activity is correlated to one or more K-12 science, technology, engineering or math STEM educational standards. Particulates can be captured on a filter, which can then be weighed or analyzed. Students are also introduced to the technology used in the subsequent activities—a low-cost air quality monitor that was developed and is used by mechanical and environmental engineers at the University of Colorado Boulder.
Within the field of air quality, researchers specialized in many other specific topics. Our atmosphere is a complex system that interacts with the hydrosphere, geosphere and the biosphere. Summary This lesson conveys core information about why air quality is important and how engineers tackle complex environmental problems—providing a foundation for the subsequent five activities. By applying the knowledge about combustion chemistry that they gain during the pre-activity reading or lecture presentation, alternatively , students predict how the emission. Composed of 1 carbon atom and 1 oxygen atom. Doing so will make the problem more salient, helping groups see and organize around common causes, directing effort to the right places and allowing courts and regulators to function.
Scientists are generating evidence that is striking, but unevenly distributed and disconnected from the narratives that move politics and sustain pressure for action at the local level. They are also introduced to some engineering concepts such as how air quality measurements are made and how control technologies work. The three lesson parts including the associated activities focus on the prerequisites for understanding air pollution. For example, technologies like catalytic converters in cars make it possible for us to continue using fossil fuels, manufacturing, and building, while minimizing the harmful emissions. It is a secondary pollutant formed by NOx and VOCs in the presence of sunlight.
The temperature varies throughout the layers of the atmosphere. Empirical evidence is required to differentiate between cause and correlation and make claims about specific causes and effects. Atmospheric chemistry is also complex, and what we emit may disperse, may react and become something entirely different, or may stick around for a long time, depending on the particular compound and environmental conditions. Thanks for your feedback! Primary emissions are direct emissions. Complex atmospheric dynamics determine how air moves within and between these layers. The curriculum has three main components: 1. High-temperature combustion also produces nitrogen monoxide NO.
Alignment agreement: Thanks for your feedback! VOCs also include products of incomplete combustion when a carbon-fuel is not completely burned, resulting in only CO2. Alignment agreement: Thanks for your feedback! Consider visibility issues in National Parks and odors near industrial areas of cities; in addition to potential health dangers, these air quality issues can make daily life unpleasant. Advances in sensor technology have made low-cost equipment possible. Thanks for your feedback! Alignment agreement: Thanks for your feedback! Listen to any student comments. First, share an explanation of what happens when you burn fuel. A compound that is a product of incomplete combustion and is dangerous to human health. .
For example, pollution in China can make its way over North America and add to existing pollutants there. It is important for researchers to understand the atmosphere in order to better predict the fate and transport of airborne contaminants see Figure 2. The sum of the amount of NO and NO2 is the amount of NOx present; in other words NOx is a term that includes both NO and NO2. VOCs are also gas-phase compounds. Alignment agreement: Thanks for your feedback! A strong, action-oriented evidence base with specific focus on source awareness is critical to combatting air pollution, as is building coalitions of public, private and civil society organizations. In Figure 1, the yellow line shows the changing temperature at different elevations in the various layers.
This pollutant is a major greenhouse gas and thus a concern for climate change. Generated by the respiration of animals and the combustion burning of fuels that contain carbon. For example, students can design research projects that utilize existing air quality data instead of collecting their own, which is highly feasible since a great amount of data from around the planet is publically available. . This curriculum was developed as part of the Next Generation Sensors andScientists NextGenSS grant U. So what might we find in vehicle exhaust fumes? We tend to think first of asthma and respiratory problems, but some particles are so small that they can enter the blood stream through the lungs and cause inflammation leading to issues beyond our breathing.
