Preliminary studies for removal of lead from surrogate and real soils using a water soluble chelator: adsorption and batch extraction
Article Abstract:
A polymer designed at the Los Alamos National Laboratory, called Metaset-Z, was studied for its feasibility as an alternative to EDTA as chelating polymer in the removal of lead (Pb) from contaminated soil. Metaset-Z is characterized to be soluble over a wide pH range, have a high affinity for lead, and have the capability of releasing bound lead under controllable conditions. The study sought to better understand and quantify the behavior of Metaset-Z in both surrogate and contaminated soils, with a particular view towards determining the amount of adsorption and desorption of polymer under differing solution conditions such as the presence of other ions and ionic strength. In general, the study determined that Metaset-Z can be utilized as a batch extractant for Pb-contaminated soil.

Passive monitoring method for 3-ethenylpyridine: a marker for environmental tobacco smoke
Article Abstract:
The passive measurement of concentrations of 3-ethenylpyridine as a method to assess environmental tobacco smoke in the air, is discussed. This new method is said to also be complementary for monitoring of tobacco smoke on a large-scale basis.
