Plastic mattress covers help keep dander out of beds, and room air cleaners equipped with high efficiency particulate air (HEPA) filters can remove dander from the air.
The study was actually conducted in and reported on air pollution in Boston, but it pointed out that air quality levels even below current standards set by the Environmental Protection Agency still pose risks to people who breathe particulate air pollution.
These measurements were then correlated with data on fine particulate air pollution.
High Efficiency Particulate Air (HEPA) filters, which usually last a year.
"We're talking about one invisible way of dying early -- by cancer, in Chernobyl -- versus another way: fine particulate air pollution, " said Frank N. von Hippel, a nuclear physicist and Princeton University professor.
Prof Kevin McConway, a statistician at the Open University said, based on the findings, if Newcastle were to halve its current particulate air pollution level it would lead to two or three fewer low weight babies out of the total 3, 500 or so born in the city each year.
The approximate stand-still of global temperature during 1940-1975 is generally attributed to an approximate balance of aerosol cooling and greenhouse gas warming during a period of rapid growth of fossil fuel use with little control on particulate air pollution, but quantitative interpretation has been impossible because of the absence of adequate aerosol measurements.

The recirculated air usually passes through high-efficiency particulate (HEPA) filters before delivery into the cabin.
This will allow truckers to reduce emissions significantly (diesel emissions include nitrous oxides, particulate matter, and other air toxics and they are a major source of pollution in some areas).
The new study looked at how much metal this so-called particulate matter is contained in the air of underground train systems.
Breathing particulate-laden (aka smoggy) air may be hardening your arteries faster than normal, according to research published today in PLOS Medicine.
Consider, for example, a spate of new studies that have found a rather convincing correlation between the presence of small particulate matter (PM2.5, the fine particles blown into the air by road traffic, coal-fired power plants, industrial manufacturing, and residential wood fuel combustion) and both obesity and diabetes.

To provide air monitoring capabilities to third world citizens, CSIRO has developed a tool that measures fine particulate levels.
Raun and Ensor conclude that federal air quality standards are adequate where ozone levels are concerned (at 75 parts per billion), but that lives would be saved if particulate matter standards were tightened below the current level of 35 micrograms per cubic meter of air.
