Using passive air samplers to assess local sources versus long range atmospheric transport of POPs

Using passive air samplers to assess local sources versus long range atmospheric transport of POPs.

Passive air samplers (PAS) are cost-efficient tools suitable for spatial mapping of atmospheric concentrations of persistent organic pollutants (POPs). The objective of this study was to use PAS to (i) determine atmospheric concentrations of selected POPs in Norwegian coastal zones with consumption advisories on seafood (N = 22), and (ii) evaluate a simple nested monitoring approach to assess t...

Measurement of Air Pollution in Kuwait City Using Passive Samplers

Measurements of gaseous SO2, NO, NO2, H2S, O3, NH3 and VOCs, in Kuwait city using IVL passive sampler technology, were obtained on monthly basis during the period from March 2011 to February 2012 at 10 locations. The results of this study reveal that those compounds had low concentrations compared to Kuwait Environment Public Authority standards for residential areas. It is found that nitrogen ...

Global Aquatic Passive Sampling (AQUA-GAPS): using passive samplers to monitor POPs in the waters of the world.

The Stockholm Convention (SC) on persistent organic pollutants (POPs) has highlighted the global risk(s) posed by organic contaminants that are persistent, bioaccumulate, are prone to long-range transport, and have the potential to cause adverse effects in humans and wildlife (1). As a result of the SC, monitoring programs are underway to record concentrations of POPs across the globe over time...

A Model Using Local Weather Data to Determine the Effective Sampling Volume for PCB Congeners Collected on Passive Air Samplers

We have developed and evaluated a mathematical model to determine the effective sampling volumes (Veff) of PCBs and similar compounds captured using polyurethane foam passive air samplers (PUF-PAS). We account for the variability in wind speed, air temperature, and equilibrium partitioning over the course of the deployment of the samplers. The model, provided as an annotated Matlab script, pred...
