This means that a reduction in fine particulate matter levels should provide health benefits in terms of lower hospital admissions for the elderly.
U.S. PIRG has again attempted to scare the public regarding particulate matter pollution.
My Turn is the distilled bathwater of Mrs. Reagan's life. It is for the most part sweetish, with a tart edge of rebuke, but disappointingly free of dirt or particulate matter of any kind.

This durable, patented low-cost filter design bridges the gap between low-efficiency diesel-oxidation catalysts and expensive, heavily catalyzed particulate filters. The wire-mesh filter system is designed to work synergistically with a fuel-borne catalyst (FBC) for reliable performance. This combined FBCCWMF technology is especially suited to solving the challenging problem of delivering a reliable pollution control solution which can be easily retrofitted for the older, higher-emission diesel engines expected to be in service for years to come. CDT will be offering licensing opportunities and technology transfer programs for the CWMF technology to establish manufacturing and distribution partnerships that meet worldwide retrofit and original equipment manufacturer needs.
Based on the best available science that we have studied to date, EPA has a proposal for public comment that aims to protect public health and improve air quality while recognizing that the science of particulate matter continues to evolve and contains uncertainties on many levels.
