   Global dimming

   Increased pollution causes more particulates and thereby creates clouds consisting of a greater number of smaller droplets (that is, the same amount of water is spread over more droplets).
2. close

   Pollution

   Air pollution, the release of chemicals and particulates into the atmosphere. ... Water pollution causes approximately 14,000 deaths per day, mostly due to contamination of drinking water by untreated sewage in developing countries.
3. close

   Light pollution

   Like other forms of pollution, such as air, water and noise pollution, light pollution causes damage to the environment.
4. close

   Air pollution

   Volcanic activity, which produce sulfur, chlorine, and ash particulates. ... Direct causes of air pollution related deaths include aggravated asthma, bronchitis, emphysema, lung and heart diseases, and respiratory allergies.
5. close

   Particulate

   Some particulates occur naturally, originating from volcanoes, dust storms, forest and grassland fires, living vegetation, and sea spray. ... Air pollution
6. close

   Environment of China

   Water pollution is a source of health problems across the country, and air pollution causes up to 1,750,000 premature deaths each year.

   Ship tracks

   Climate change feedbacks and causes Particulates
8. close

   Air pollution dispersion terminology

   If the pollutants in the plume are subject to depletion by contact with the ground (particulates, for example), the concentration increase just downstream of the building or structure will decrease the concentrations further downstream. ... Air pollution

   Air Pollution Index

   The WHO also introduced new measurement guidelines for very small particulates which are more dangerous to pulmonary function. ... ↑ "Air Pollution Index".
10. close

    Black carbon

    Public health benefits of particulate matter reductions have been recognized for years. The WHO estimates that air pollution causes nearly two million premature deaths per year.
