AirQ+ is intended as a tool to ascertain the magnitude of the burden and impacts of air population on health in a given locality. [7] It performs this function by featuring data analysis, graphing tools, tables and quantitative information for prominent pollutants such as particulate matter (PM), nitrogen dioxide (NO 2), and tropospheric ozone (O 3).
Air pollution emission factors are usually expressed as the weight of the pollutant divided by a unit weight, volume, distance, or duration of the activity emitting the pollutant (e.g., kilograms of particulate matter emitted per megagram of coal burned). The factors help to estimate emissions from various sources of air pollution.
The study found that people living in the most polluted city (Steubenville) were 26 percent more likely to die than those in the least polluted city (Portage), [7] [11] suggesting an association between particulate pollution and higher death rates in urban areas: "Although the effects of other, unmeasured risk factors cannot be excluded with ...
A questionnaire is a research instrument that consists of a set of questions (or other types of prompts) for the purpose of gathering information from respondents through survey or statistical study. A research questionnaire is typically a mix of close-ended questions and open-ended questions.
It is a health protection tool used to make decisions to reduce short-term exposure to air pollution by adjusting activity levels during increased levels of air pollution. The Air Quality Health Index also provides advice on how to improve air quality by proposing a behavioral change to reduce the environmental footprint.
Air pollution measurement is the process of collecting and measuring the components of air pollution, notably gases and particulates. The earliest devices used to measure pollution include rain gauges (in studies of acid rain ), Ringelmann charts for measuring smoke , and simple soot and dust collectors known as deposit gauges . [ 1 ]
Different methods can be useful for checking a questionnaire and making sure it is accurately capturing the intended information. Initial advice may include: consulting subject-matter experts; using questionnaire construction guidelines to inform drafts, such as the Tailored Design Method, [1] or those produced by National Statistical ...
The Centre for Research on Energy and Clean Air (CREA) is a nonprofit think tank researching energy and air pollution. [1] CREA was founded in Helsinki in 2019 with the goal of tracking the impacts of air pollution by providing data-backed research products.
