Isotopic characterization of chlorinated solvents—laboratory and field results
TLDR
In this article, a purge-and-trap unit was used to extract chlorinated solvents for isotope analyses, and the results showed that the purification unit produces both accurate and reproducible results for dissolved chlorinated solvent δ 13 C and δ 37 Cl analyses.About:

Lead (Pb) isotopic fingerprinting and its applications in lead pollution studies in China: A review
Hefa Cheng,Yuanan Hu +1 more
TL;DR: The history and current status of lead pollution in China is summarized, the power of Pb isotopic fingerprinting is illustrated with examples of its recent applications in investigating the effectiveness of leaded gasoline phase-out on atmospheric lead pollution, and the sources of PB found in various environmental media.

Production and characterization of synthetic wood chars for use as surrogates for natural sorbents
TL;DR: In this paper, the authors presented a scientific approach to the production of synthetic wood char that has properties of a natural wood char produced by forest fire, and the natural char examined for this purpose was that of a pitch pine obtained from the New Jersey Pine Barrens.

A review of immiscible fluids in the subsurface: properties, models, characterization and remediation
James W. Mercer,Robert M. Cohen +1 more
TL;DR: In the past few years, as hazardous waste sites have been studied more often and in more detail, immiscible fluids have been encountered in the subsurface with greater frequency as discussed by the authors.

Dense chlorinated solvents in porous and fractured media : model experiments
F. Schwille,James F. Pankow +1 more
TL;DR: The results of 20 years of research by the world's leader to help develop a genuine understanding of the behavior of the all-pervasive dense chlorinated solvents in the vadose and unsaturated zones are presented in this paper.

Dissolution of dense chlorinated solvents into groundwater. 2. Source functions for pools of solvent
TL;DR: In this paper, the dissolution rate depends on the molecular diffusion coefficient, the vertical dispersivity α v, the groundwater velocity v, the solubility, and the pool length, and a value for α v for dissolution of trichloroethylene in a sand-filled physical model was found to be ∼ 0.00023 m
