Passive in situ samplers for dissolved and sediment-associated organic contaminants

State Key Laboratory of Organic Geochemistry, Guangzhou Institute of Geochemistry, Chinese Academy of Sciences, Guangzhou 510640, ChinaCoastal waterways draining highly urbanized landscapes serve as conduits of potentially toxic pollutants such as polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs) and chlorinated pesticides (e.g. DDTs and chlordanes) to the receiving estuarine/marine environment. Decades long discharge has resulted in contaminant accumulation in nearshore environments such as bays, harbors, marinas and rivermouths, impacting sediment and water quality. Because these compounds have very low aqueous solubility and current measurement technology is not cost-effective, however, little or no data for aqueous concentrations in situ exist, making the determination of loadings (e.g. Total Maximum Daily Loads or TMDLs) difficult at best. Recently developed passive samplers based on solid phase microextraction (SPME) technology and sorption to polyethylene (polyethylene devices or PEDs), however, have made it possible to quantify ultra-trace levels of pollutants in situ at a fraction of the cost and with a much quicker turnaround time than traditional techniques. Disadvantages associated with these passive sampling alternatives, however, are the extended time to reach equilibrium in situ as well as the degree of pre-deployment calibration required to determine equilibrium partitioning parameters. Over the past several years, SCCWRP and CAS have collaborated in cataloguing SPME parameters for a large number of organic analytes, including most organic contaminants that are currently being considered for regulation. A new collaboration between SCCWRP and LMU will calibrate PEDs for selected TMDL regulated organics, and in a subsequent phase, compare the performance of SPME and PED samplers under controlled lab and field conditions.Location: Kaprielian Hall (KAP) - rielian Hall, Room 156

From Electrons To Finite Elements: A Concurrent Multiscale Approach For Metalsby
Gang LuDepartment of Physics, California State University, Northridge, CA 91330-8268In this talk, I will discuss how multiscale modeling can be applied to study (1) Hydrogen
enhanced local plasticity in Al, which is crucial to understanding of H embrittlement of
metals. The atomic and electronic mechanism for enhanced dislocation mobility is
explored; (2) Ductile fracture in Al under mode I loading. The atomistic mechanisms of
dislocation nucleation from the crack tip, and crack propagation are investigated. The
electronic states at the crack tip during the fracture process are examined in detail.
Multiscale modeling of material properties has emerged as one of the grand challenges in
materials science and engineering. Multiscale modeling is necessary because the
macroscopic properties of materials are largely determined by the microscopic processes,
taken place particularly at lattice defects. A typical example is the mechanical response of
metals to external loads, which is characterized as ductile or brittle at the macroscopic
scale, depending on the ability of the material to absorb the load by plastic deformations.
This response can be drastically altered by the presence of impurities and their influence
on bonding between the atoms in crucial regions like the crack tip and dislocation core.
The delocalized nature of electronic states in a metal makes the description of such
effects particularly challenging. We have recently developed a multiscale modeling
approach that concurrently couples quantum mechanical calculations for electrons, to
empirical atomistic simulations for classical atoms, and to continuum mechanical
modeling for finite elements, in a unified description [1]. In specific, the electronic
structure calculations are performed with the plane-wave pseudopotential method based
on the density-functional theory (DFT), the classical atomistic simulations with the
embedded-atom method (EAM), and the continuum modeling with the Cauchy-Born rule
in the local Quasicontinuum (QC) formulation [2]. The multiscale method is
implemented in the context of the QC framework with the additional capability to include
DFT calculations for a selection of non-local QC atoms. A novel coupling scheme has
been developed to combine the DFT and EAM calculations [3] in a seamless fashion to
deal with non-local QC atoms.
