Book Description
(Cont.) KPEWs for eleven PAHs and PCBs were found to correlate closely with octanol-water equilibrium partitioning constants (Kows; log KPEW = 1.1 log Kow-0.45, R2 = 0.85). Temperature and salinity dependence of KPEW for the chemical of interest can be predicted with that chemical's excess enthalpy of solution and Setschenow constant, respectively. DpEs for several HOCs were measured in the laboratory so that the time for equilibrium uptake in the field could be predicted. PEDs allowed for quick, in situ, time-averaged measurements of phenanthrene and pyrene at pM concentrations and PCB #52 at fM concentrations in Boston Harbor seawater. Observations of disequilibrium between sorbed HOCs (e.g., PAHs & PCBs) and the surrounding environmental waters indicate that the times for desorption are important for understanding the fate of HOCs. Settling and resuspended particles can play a significant role in the cycling of HOCs. For PAHs, like pyrene, these chemicals' strong affinity for black carbon in the environment makes the rate of desorption less certain. The desorption rate for pyrene from native Hudson River sediment was measured in the laboratory and a diffusion rate constant (effective diffusivity/particle radius2) ranging from 1. OE-7 to 5.6E-7 s-1 was measured. The results were in good agreement with a physically- and chemically-based model for estimating effective diffusivity and the rate of desorption.

Book Description
This work details water sampling and preservation methods by enumerating the different ways to measure physical, chemical, organoleptical, and radiological characteristics. It provides step-by-step descriptions of separation, residue determination, and cleanup techniques for a variety of fresh- and salt-waters. It also discusses information regarding the analysis and detection of bacteria and algae.
