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...
متن کاملGlobal 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...
متن کاملField calibration of low density polyethylene passive samplers for gaseous POPs.
A field calibration study of low density polyethylene (LDPE) for measuring atmospheric concentrations of persistent organic pollutants (POPs) was performed in East Providence (RI), USA. LDPE samplers were collected after 3, 7, 10, 14, 17 and 21 days of exposure along with samples from a co-deployed high volume sampler. Uptake kinetics of POPs by LDPEs were confirmed both by using an uptake stud...
متن کاملAn inexpensive video data capture system
Digital mapping techniques are used increasingly in hydrology. One of the constraints on the application of those techniques is the digitizing process, which can be costly and time consuming. This paper describes the background and development of a low cost, easy-to-use system for digitizing maps, based on the use of a video camera as a scanner, and goes on to discuss the application of this sy...
متن کاملRecommendations for Genetic Variation Data Capture in Developing Countries to Ensure a Comprehensive Worldwide Data Collection
Developing countries have significantly contributed to the elucidation of the genetic basis of both common and rare disorders, providing an invaluable resource of cases due to large family sizes, consanguinity, and potential founder effects. Moreover, the recognized depth of genomic variation in indigenous African populations, reflecting the ancient origins of humanity on the African continent,...
