Multiscale Modeling of Atmospheric Pollution Formation and Feedbacks: Air and Energy Research at the United States EPA

In order to support both robust enforcement of clean air regulations and effective management of air quality in the United States, the U.S. Environmental Protection Agency charges scientists in its Office of Research and Development with maintaining a comprehensive atmospheric research program, building tools for air quality analysis, and anticipating future problematic air pollution issues. This seminar will cover a …

Insights into molecular steps of secondary aerosol formation in the polar atmospheres

Major fraction of arctic and polar cloud condensation nuclei (CCN), upon which cloud droplets form, are of secondary origin, i.e., they are formed from gas phase via homogeneous nucleation and subsequent cluster growth by condensation of low volatile vapours. The low volatile vapours required in the process are formed in gas phase oxidation of both biogenic volatile compounds and anthropogenic …

Secondary Electrospray Ionization Mass Spectrometry for Medical Diagnosis of Respiratory Diseases

Exhaled breath contains relevant information on a person’s health status. Our vision is to use real-time and completely non-invasivechemical analysis of exhaled breath for applications such as medical diagnosis, monitoring progress and treatment of diseases, drug compliance, pharmacokinetics, and others. The methodology we use to analyze breath in real time is based on secondary electrospray ionization coupled to high-resolution mass spectrometry (SESI-HRMS). It …

“Particle formation” vs. “particle growth”: Robust metric for determining the onset of condensational growth of nanoparticles

I’ll discuss how to robustly model and interpret observations of formation of atmospheric nanoparticles from condensable vapors and their growth in the nanometer size range. Correct representation of these processes is critical for resolving particle formation mechanisms, and for quantifying atmospheric particle loadings and effects.

How to End the Current Misrepresentation of Science in International Chemicals Management

The purpose of the seminar and the following meeting is to twofold: First, to report on observations and lessons learned regarding the science representation (or rather misrepresentation) at recent international chemicals management meetings, including the 4th session of the international conference of chemicals management (ICCM4) in 2015, the 12th and 13th meetings of the POP Review Committee of the Stockholm …

Lessons Learned from Two Decades of research on Uncovering Emerging Contaminants and their Impacts by Mass Spectrometry

In the last twenty years, thousands of research papers covering different aspects of emerging contaminants have been published, ranging from environmental occurrence to treatment and ecological effects. Emerging contaminants are environmental pollutants that have been investigated only in the last 20 years, and include man-made and naturally occurring chemicals such as pharmaceuticals, personal care products, illicit drugs, engineered nanomaterials, and antibiotic resistance …
