Ozone , a gas, is a major part of air pollution in cities. (medlineplus.gov)
The estimates are from the Indian Institute of Tropical Meteorology's (IITM) decision support system (DSS), which provides a forecast for Delhi's air quality and identifies the components of the pollution, which at present includes a spike in all major sources. (hindustantimes.com)
Air pollution is a major environmen- tal risk to health in both developed and developing countries. (who.int)
Although institutional capacities are limited in this from those in other parts of the world, in part due to the regard, there are still numerous WHO resources available arid nature and high prevalence of natural dust, as well to help countries understand their air pollution problems as the widespread practice of biomass and solid waste and identify priority actions and interventions to protect burning. (who.int)
This is largely a result from healthy ambient air quality, countries must address the increased morbidity and mortality attributed to stroke, major sources of air pollution in different contexts and heart disease, chronic obstructive pulmonary disease, resource settings. (who.int)

Others hypothesize the source of Venus' dust ring is a group of never-before-detected co-orbital asteroids. (scitechdaily.com)
15 °C) would benefit from improved understanding of the organic species associated with IN-activity, the extent to which the organic contribution to IN-activity varies across source regions, and whether the ns approach is appropriate or whether an alternative approach is required for skillful representation of dust INPs in this sensitive temperature regime. (calisphere.org)
The most important dust origins are Source 1, 2 and 3, each having a dust production of over 200 Mt per year. (kma.go.kr)
Dust production from Source 4 is relatively weak. (kma.go.kr)
In the United States, the major source of lead exposure among children is lead-based paint and lead-contaminated dust found in buildings built before 1978. (cdc.gov)

The plume of dust that swept over the South Pacific Ocean from Australia on October 13, 2009, was delicate, almost ghostly, compared to the large, dense plume of dust that darkened much of the east Australian coast on September 23. (nasa.gov)

Wash children's hands, bottles, pacifiers and toys often, and regularly clean floors, window sills, and other surfaces to reduce potential exposure to lead dust. (nachi.org)

This may cause concentrations and relative abundance of the contaminants found to differ notably from those in dust from terrestrial indoor micro-environments. (theiet.org)
