Next step for EPA's new air quality regs: monitoring
Article Abstract:
Even as the Environmental Protection Agency (EPA) finalized a plan to regulate fine particulates (PM-2.5), most states are not prepared to comply with the Clean Air Act which calls for the monitoring of PM-2.5. Most states do not have PM-2.5 monitors and only about 200 of the monitors exist nationwide. The EPA has said that around 1500 monitoring stations are still needed to adequately assess the public health risk that PM-2.5 poses. The agency is asking for an appropriation of $100 mil to help states purchase the monitoring equipments which may cost between $6000 and $20,000 each.

Determination of platinum at trace levels in environmental and biological materials
Article Abstract:
A summary of a recent research on the determination of platinum and other precious metals in dust, vegetation, soil, water, and biological materials is presented. The study utilized a number of instrumental methods in determining the traces of platinum in the various categories of environmental samples. Inductively coupled plasma-mass spectography (ICP-MS) is the ideal instrumental technique for simultaneous determination of several elements besides platinum. AS and nuclear methods, meanwhile, prove most sensitive in determining platinum alone.

Platinum and rhodium concentrations in airborne particulate matter in Germany from 1988 to 1998
Article Abstract:
Experiments in Frankfurt, Germany using twenty samples of air and airborne dust show a 46 and 27 fold increase in PT and Rh concentrations between 1988 and 1998, largely due to the use of the automobile catalytic converter. The article includes supporting graphs, charts and statistical data.
