The Air Quality Health Index (AQHI) is a scale designed in Canada to help understand the impact of air quality on health. 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.
According to the Childcare Resource and Research Unit (CRRU) 249-page annual report, "Early Childhood Education and Care in Canada 2019", which was partially funded by the federal government's Employment and Social Development Canada's (ESDC) Social Development Partnerships program, past attempts at advancing child care programs have been made in 1984, 1987, 1993, 2003, and 2005.
An individual score (Individual Air Quality Index, IAQI) is calculated using breakpoint concentrations below, and using same piecewise linear function to calculate intermediate values as the US AQI scale. and The final AQI value can be calculated either per hour or per 24 hours and is the max of these six scores.
Thus an AQI of 100 does not mean twice the pollution of AQI at 50, nor does it mean twice as harmful. While an AQI of 50 from day 1 to 182 and AQI of 100 from day 183 to 365 does provide an annual average of 75, it does not mean the pollution is acceptable even if the benchmark of 100 is deemed safe. This is because the benchmark is a 24-hour ...
The Canadian Child Care Federation (CCCF) is Canada's largest national service-based early learning and child care organization. Registered as a charitable status non-profit with Canada Revenue Agency since 1987, CCCF is a federation of 20 provincial/territorial organizations from across the country, representing 9,000 members – practitioners, academics, parents and policy makers.
Asthmatic airway versus normal lungs' airway. The Government of Canada estimates that 14,600 premature deaths per year in Canada can be linked to air pollution from fine particulate matter, nitrogen dioxide and ozone, from the report Health Impacts of Air Pollution in Canada – Estimates of Morbidity Outcomes and Premature Mortalities - 2019.

Since indoor air pollutants can adversely affect human health, it is important to have real-time indoor air quality assessment/monitoring system that can help not only in the improvement of indoor air quality but also help in detection of leaks, spills in a work environment and boost energy efficiency of buildings by providing real-time ...
