Passive Air Sampling of PCDD/Fs, PCBs, PAEs, DEHA, and PAHs from Informal Electronic Waste Recycling and Allied Sectors in Indian Megacities Open
Xenobiotic chemical emissions from the informal electronic waste recycling (EW) sector are emerging problem for developing countries, with scale and impacts that are yet to be evaluated. We report an intensive polyurethane foam disk passiv…

Impacts of New Particle Formation on Short-term Meteorology and Air Quality as Determined by the NPF-explicit WRF-Chem in the Midwestern United States Open
New particle formation (NPF) from nucleation and subsequent nuclei growth, which is frequently observed in the troposphere, is critical to aerosol-cloud interactions yet difficult to simulate. In this work, regional simulations with the fu…

National Athletic Trainers' Association Position Statement: Facilitating Work-Life Balance in Athletic Training Practice Settings Open
Objective: To illustrate the concept of work-life balance and those factors that influence it and to provide recommendations to facilitate work-life balance in athletic training practice settings. To present the athletic trainer with infor…

Parse, simulation, and prediction of NOx emission across the Midwestern United States Open
Accurately constraining N emissions in space and time has been a challenge for atmospheric scientists. It has been suggested that 15N isotopes may be a way of tracking N emission sources across various spatial and temporal scales. However,…

A New MODIS C6 Dark Target and Deep Blue Merged Aerosol Product on a 3 km Spatial Grid Open
In Moderate Resolution Imaging Spectroradiometer (MODIS) Collection (C6) aerosol products, the Dark Target (DT) and Deep Blue (DB) algorithms provide aerosol optical depth (AOD) observations at 3 km (DT3K) and 10 km (DT10K), and at 10 km r…

Calibration and evaluation of PUF-PAS sampling rates across the Global Atmospheric Passive Sampling (GAPS) network Open
Here we present and evaluate a method to determine PUF-PAS sampling rates (RS), and the effective sampling volume (Veff), for gas-phase chemical compounds deployed anywhere in the world.

Simulated mussel mortality thresholds as a function of mussel biomass and nutrient loading Open
A freshwater “mussel mortality threshold” was explored as a function of porewater ammonium (NH 4 + ) concentration, mussel biomass, and total nitrogen (N) utilizing a numerical model calibrated with data from mesocosms with and without mus…
