Air Toxics/Ozone Precursor Analyses by Thermal Desorption-GC or GC/MS
The following air-quality testing applications are demonstrated:
Analysis of air toxics by U.S. EPA Method TO-17 - PerkinElmer, in accordance with established methodologies, developed an Air Toxics Analyzer, which integrates thermal desorption with GC/MS into a single, unified system solution, allowing characterization of airborne toxics specified in U.S. EPA Method TO-17.
Analysis of ozone precursors by U.S. EPA Clean Air Act – PerkinElmer, in conjunction with the U.S. EPA, developed an analyzer and methodology for collecting and automatically measuring C2-C11 without the use of liquid cryogen, allowing unattended operation with automatic system calibration and full data processing. |

An Overview of Speciated Inorganic Analysis in Water
The measurement of metals in environmental, clinical, and industrial matrices is well established and can provide information on quality, nutrition and other important parameters. But does the total metal content of each element give us enough information to make decisions on metabolism, bioavailability, and mobility in the environment or human body? Speciated analysis, describing the metal content in terms of valence state or organic compound, can provide additional information that can be used to more completely understand the action of metals in our world. |

Blood Lead Analysis by GFAA or ICP-MS
Human exposure to lead through the workplace or home environment can lead to accumulation of toxic levels in blood, leading to high blood pressure, fertility problems, and nerve and joint pain. More insidious, exposure of children to subclinical lead levels can lead to behavioral and learning problems. |

Environmental Part 1 - Water-Quality Testing by Headspace Trap-GC/MS
Details and suggestions on how to use headspace trap sample-handling technology to comply with U.S. EPA Method 8260B are given. In addition to method compliance, this technology provides significant advantages over previous sample-introduction systems. Advantages such as increased sample throughput by overlapped thermostatting, no cross-contamination of samples from using the same purge vessel and better recovery of compounds with poor purging efficiencies such as alcohols and ketones, are discussed. Both drinking and waste-water detection are shown. |

Environmental Part 2 - Volatile Organic Analysis by Headspace Trap-GC/MS
Part 2 of this two-part webcast is designed to discuss results that comply with current U.S. EPA methodologies (8260B) using the headspace-trap system. An update of the progress on the U.S. EPA headspace-trap method development is also provided. In addition to method compliance, this technology provides significant advantages over previous sample-introduction systems. Advantages such as: increased sample throughput by overlapped thermostatting, no cross-contamination of samples from using the same purge vessel and better recovery of compounds with poor purging efficiencies, such as alcohols and ketones, are discussed. |

Environmental Monitoring in China and Southeast Asia
The nations of the Pacific Rim have become increasingly concerned about environmental issues due to a number of factors. Some of these include: the fear that climate change may result in ocean levels rising and, with their large areas of low lying coastal regions, may cause major dislocations; the increasing awareness that pollutants migrating through the atmosphere from neighboring countries are adversely impacting their ecosystems; the increased threat to the health of their populations that pollution of air and water is having; the economic and health impact that water pollution is having on the food that they grow and catch; and the tremendous impact pollution is having on the health and well being of the population of some of these countries. |

Methods Development and Validation in United States Environmental Regulatory Programs
Test Methods for Evaluating Solid Waste, also known as SW-846, is the compendium of analytical and test methods approved by EPA's Office of Solid Waste (OSW) for use in determining regulatory compliance under the Resource Conservation and Recovery Act RCRA). SW-846 functions primarily as a guidance document setting forth acceptable, although not required, methods to be implemented by the user, as appropriate, in responding to RCRA-related sampling and analysis requirements. |

"This Thing Called Water"
Listen to this compelling speech by Bill Bertera, executive director of the Water Environment Federation (WEF). Speaking in New Orleans still rebuilding from the ravages of Hurricane Katrina, Mr. Bertera talks about how important water is to us every day. Our need to have access to fresh, clean, untainted sources of water. How water or the lack of it affects every human being and organism on the planet. Learn about how much water there is on Earth and how much water we actually use. A truly enlightening talk that will open your eyes to the global need to manage this incredible resource called water. |
