Bangladesh was the most polluted country, while New Delhi, India, is the world’s most polluted capital. The countries with the worst air pollution were India, Pakistan and Bangladesh, all exceeding WHO guidelines by 10 times.
Denmark. With a total EPI score of 82.5, Denmark is 2020’s cleanest and most environmentally friendly country. Denmark stands out for its high scores in several categories, including Wastewater Treatment (100), Waste Management (99.8), and Species Protection Index (100).
- ground-level ozone
- particle pollution (also known as particulate matter, including PM2.5 and PM10)
- carbon monoxide
- sulfur dioxide
- nitrogen dioxide
The United States Environmental Protection Agency measures five major pollutants, all of which are regulated via the Clean Air Act. Of these, particle pollution is the most commonly monitored. The World Health Organization evaluated the concentration of PM2.5 particles to determine the most polluted place on Earth. PM2.5 (fine particulate matter 2.5) refers to tiny particles or droplets in the air that are 2.5 microns (µg) or less in diameter.
aerosol sprays. cleansers and disinfectants. moth repellents and air fresheners. stored fuels and automotive products.
In most guidelines, a concentration of less than 0.5 mg/m3 is deemed acceptable, along with a stipulation that any specific compound being tracked should not exceed 250 ug/m3.
When you smell a “musty-moldy” odor, it’s generally the VOC you are noticing. VOC are often considered irritants to mucus membranes, however, are also capable of both short-term and long-term adverse health effects. Symptoms of mold exposure may include headache, sore throat, runny nose, coughing, sneezing, watery eyes and fatigue. In those with asthma, asthma attacks can occur. In those with impaired immune systems, serious infection can occur.
The Sensedge is the first in the industry to use removable sensor modules to replace the traditional, costly calibration processes for long-term accuracy with minimal maintenance. Kaiterra is the company that manufacture this product.
Integrate with Building Automation System using BACnet
With support for BACnet/IP, real-time air quality data can be seamlessly integrated into existing Building Automation Systems (BAS), such as Johnson Controls METASYS, Honeywell WEBs-N4 and WEBs-AX, Schneider Electric EcoStruxure, and Siemens Desigo.
The Sensedge supports simultaneous connections to the cloud for data reporting, and BACnet for local building automation.
A very good product that i will suggest.
