India pollution monitors overwhelmed by toxic smog
Phys.org ·
The Brief
- India's air pollution monitors were overwhelmed this week by smog.
- Pollutant concentrations exceeded the monitors' upper measurement limit.
- Regulators said the concentrations were equivalent to 66 times the World Health Organization's recommended daily maximum.
Why it matters
When monitors cannot read levels above their upper limit, regulators lose accurate data on the most dangerous pollution episodes, and the reported exposure is far above WHO's daily guideline.
Who’s affected
- people exposed to air pollution in India
- air quality regulators
- public health researchers
India's air pollution monitors were overwhelmed this week by toxic smog so severe that concentrations exceeded their upper measurement limit, equivalent to 66 times the World Health Organization's recommended daily maximum, regulators said.
