Intraurban variability of Ambient PM Arsenic and other air toxics metals case study
The Missouri Department of Natural Resources (MoDNR) and Washington University participated in a project to collect and analyze air toxics metals data. It was funded through a Community Air Toxics Grant from the U.S. Environmental Protection Agency (USEPA). The study grew out of the southside St. Louis Community Air Project (CAP) which identified six hazardous air pollutants of concern including ...

Background Concentrations of 18 Air Toxics for North America
ABSTRACT Of the 188 hazardous air pollutants, or 'air toxics,' identified by the U.S. Clean Air Act, 18 were targeted as the most important in a 10-city pilot study conducted in 2001 and 2002 as part of the National Air Toxics Trend Sites Program. This paper describes the pilot study. The U.S. Clean Air Act identifies 188 hazardous air pollutants (HAPs), or “air toxics,” associated with ...

Maritime emissions treatment system (METS)
In January 2014, the California Air Resources Board (CARB) began enforcement of the "Airborne Toxic Control Measure for Auxiliary Diesel Engines Operated on Ocean-Going Vessels At-Berth in a California Port" Regulation, commonly referred to as the At-Berth Regulation. Covering all six ports in California, the At-Berth Regulation requires a 50% reduction in emissions from auxiliary diesel engines ...

Don’t Let the Welding Fume Plume Make You Sick
What’s at Stake? Welding poses a unique combination of both safety and health risks to more than 500,000 workers in a wide variety of industries. The risk from fatal injuries alone is more than four deaths per thousand workers over a working lifetime. What’s the Danger? The fume plume is the clearly visible column of fume that rises directly from the spot of welding or cutting. ...

Criteria and Air-Toxic Emissions from In-Use Automobiles in the National Low-Emission Vehicle Program
The U.S. Environmental Protection Agency (EPA) implemented a program to identify tailpipe emissions of criteria and air-toxic contaminants from in-use, lightduty low-emission vehicles (LEVs). EPA recruited 25 LEVs in 2002 and measured emissions on a chassis dynamometer using the cold-start urban dynamometer driving schedule of the Federal Test Procedure. The emissions measured included ...
