The Atmosphere and Human Health 1

Assess the impact of human activities on indoor and outdoor air quality and the need for regulations and mitigating technologies to minimize risks to human health.

## Indicators

**a. Pose questions regarding how human activities and technologies have influenced air quality.**

https://www.canada.ca/en/environment-climate-change/services/environmental-indicators/air-pollution-drivers-impacts.html This website has all differnts ways of how humans impact the air quality. Drviers impact the air quality and can create smog and acid rain from the polutions that goes in the air from driving. D.S

https://www.who.int/phe/air\_quality\_q&a.pdf - Article made by World Health Organization. Answers frequently asked questions about air pollution.

https://www.nationalgeographic.org/topics/resource-library-human-impacts-environment/?q=&page=1&per\_page=25 A webpage with videos and articles about environmental issues and how they we can help-EB.

**b. Investigate the role of stratospheric ozone layer depletion as a contributor towards human health issues such as cancers and cataracts.**

https://ec.europa.eu/clima/policies/ozone\_en#:~:text=Ozone%20layer%20depletion%20causes%20increased,cataracts%20and%20immune%20deficiency%20disorders.&text=UV%20rays%20also%20affect%20plant%20growth%2C%20reducing%20agricultural%20productivity. This website provides information on how ozone layer depletion causes increased UV radiation levels at the Earth's surface, which is damaging to human health. Negative effects include increases in certain types of skin cancers, eye cataracts and immune deficiency disorders. UV radiation also affects ecosystems, which damages food chains and biochemical cycles. UV rays also affect plant growth, which reduces agricultural productivity. -KTMP

**c. Describe the sources of indoor and outdoor air pollutants such as particulate matter, sulphur dioxide, nitrogen dioxide, volatile organic chemicals (VOCs), carbon monoxide, lead, tropospheric ozone, sulphuric acid, radon, mould and allergens and their potential effects on human health.**

https://www.cdc.gov/nceh/publications/books/housing/cha05.htm This article talks about the different air pollutants carbon monoxide, ozone, volatile organic chemicals, radon, and lead. However it also talk about biologic pollutants, mold, tobacco smoke, pesticides, asbestos, and arsenic, Each pollutant described has how to control hazards, owner's responsibilities, with things like lead or pesticides, local ordinances, as well as what it is, what causes it, and the potential health hazards associated with the pollutant. This article relates to this indicator because it talks about most of the pollutants describes in the indicator as well as other pollutants. It offers plenty of information for each pollutant as well. -TC https://www.iqair.com/newsroom/indoor-air-pollutants-dangers This article is similar to the previously mentioned, however it talks about other indoor and outdoor pollutants that weren't mentioned in the previous link. Both articles are similar in how the pollutants are described. They have similar approaches with what they describe under each pollutant in terms of potential dangers and health hazards, descriptions, causes, and a "fun" fact about each pollutant. Why I chose this link is similar to the previous link, other than this link covers the rest of the pollutants specified in the indicator. -TC

https://learn.kaiterra.com/en/air-academy/5-major-outdoor-air-pollutants This website describes how outdoor airpolution afect us, it explains what are 5 most comon outside air polutants and mantions how this polutants are being created and where they mostly prevail. This article explains how outdor air polutions affect our health after a short and long term exposure. It describes how to protect your self from air polutants as well. - AZ https://www.lung.org/clean-air/at-home/indoor-air-pollutants This websight describes how indoor air polutions affects our health. It gives a list of all posible air polutants, you can click on them and learn more. In adition you can learn how to keep polution out of your home, how to know if your air is unhealthy, and how ventilation works. It provides all information you might posibly need. - AZ

**d. Analyze the role of various government regulations (e.g., Air Quality Health Index (AQHI) and the National Ambient Air Quality Objectives (NAAQOs)), and legislation (e.g., Canadian Environmental Protection Act, 1999 and The Clean Air Act in Saskatchewan) in minimizing risks to human health.** https://www.enr.gov.nt.ca/en/environmental-protection-act

this website describes what the environmental protection act does and how it works. This website also describes the key components such as: include provisions that address waste management, include provisions for the management of contaminated sites, etc. ZB

**e. Investigate the sources and production of industrial and photochemical smog and measure that can be taken to mitigate their effects to human health.**

https://ed.ted.com/lessons/the-science-of-smog-kim-preshoff - The link above leads to a video created by Kim Preshoff. It explains what smog is made of, why smog affects some cities and not others as well as other details about the science behind smog. The main focus is on the smogs that affected Los Angeles, London, Glascow, and Edinburgh. After watching the video, there are headings on the side which lead to quizzes about the video. The "Dig Deeper" section also provides additional resources about pollution, including which cities produce the most amount of pollution, as well as websites listing methods being designed by countries across the world to help cities that are fighting smog. The website also includes a discussion post which people can debate questions. -ALA

https://www.nationalgeographic.org/video/air-pollution-101/ - This link is from National Geographic. This informative video explains the different types of pollutions such as smogs, toxic pollutants and greenhouse gases and the subcategories of smog, photochemical and sulfurous. The main focus explains where they come from, what they are made of, their effects on the environment, humans and the consequences of using them. It includes solutions as well, such as decreasing the use of fossil fuels. Explains why these solutions will help the environment and us. - RL

https://www.nationalgeographic.org/encyclopedia/smog/- this link describes the definition of smog and what it does in our atmosphere, like Today, most of the smog we see is photochemical smog. it also talks about the pollution and how it can be prevented. -WDP

**f. Design and carry out a process to collect and analyze data, using appropriate technologies, to assess indoor or outdoor air quality.**

https://teachingapscience.com/air-pollution-lab-airborne-particulates-for-distance-learning/ - This is an air pollution lab created for students who are stuck at home with online learning. It is a quick and easy lab that is more efficient during distance learning. A materials list is included as well as examples of how previous students have done the steps.
