Bioavailable Environmental Pollutant Patterns in Sediments from Passive Equilibrium Sampling

Passive sampling methods for contaminated sediments: Risk assessment and management

This paper details how activity-based passive sampling methods (PSMs), which provide information on bioavailability in terms of freely dissolved contaminant concentrations (Cfree ), can be used to better inform risk management decision making at multiple points in the process of assessing and managing contaminated sediment sites. PSMs can increase certainty in site investigation and management,...

Advancing passive sampling of contaminants in environmental science.

Improvements in pollutant monitoring: optimizing silicone for co-deployment with polyethylene passive sampling devices.

Sequestering semi-polar compounds can be difficult with low-density polyethylene (LDPE), but those pollutants may be more efficiently absorbed using silicone. In this work, optimized methods for cleaning, infusing reference standards, and polymer extraction are reported along with field comparisons of several silicone materials for polycyclic aromatic hydrocarbons (PAHs) and pesticides. In a fi...

Equilibrium thermodynamics from basin-sampling.

We present a "basin-sampling" approach for calculation of the potential energy density of states for classical statistical models. It combines a Wang-Landau-type uniform sampling of local minima and a novel approach for approximating the relative contributions from local minima in terms of the volumes of basins of attraction. We have employed basin-sampling to study phase changes in atomic clus...

Noise an Environmental Pollutant

The harmful effect of the noise on human health has been known for many decades and it's first harmful effect on the hearing came to be known in the year 1831. According to the nature of the work, this di- sease was called Boiler Maker's deafness.  Noise due to the industrial machineries is one of the main cause of Environmental Poliution, and among the different industreis, Textile industry i...
