Environmental
Engineering Analytical Chemistry Laboratory
The Environmental Engineering
Analytical Chemistry Laboratory (EEACL), under the direction of Edward
Ruth, is located in the
Department of Civil & Environmental Engineering and has been
established to provide for identification and quantification of
organic and inorganic compounds at trace levels in environmental,
biochemical and geochemical samples from atmospheric, aquatic and
solid media. Groups at UCLA requiring and utilizing these
services include Civil & Environmental Engineering, Chemical
Engineering, Institute of Geophysics & Planetary Physics,
Environmental Sciences & Engineering, Environmental and
Occupational Health Sciences and Laboratory of Biomedical &
Environmental Sciences. Outside groups include California
Institute of Technology, Oregon State University, University of
Southern California, Brookhaven National Laboratory and Western
Consortium for Public Health.
The facility is equipped with a
Finnigan 4000 gas chromatograph-mass spectrometer (GC-MS) and
Incos Data System, a Varian 3500 dual ECD gas chromatograph
(GC-ECD), a Varian 3700 FID gas chromatograph, other assorted
chromatographic equipment and Perkin Elmer atomic absorption
spectrometers.
A summary of EEACL analytical
capability is outlined below.

CURRENT EEACL
PROJECTS
The EEACL is currently providing
analysis for the following major projects:
 HMX/RDX Explosives Remeditation Project, Dr.
Michael Stenstrom, P.I.
Providing analysis at ppb levels of intermediate organic
compounds in water samples taken from basis hydrolysis and
bacteriological degradaion experiments of HMX and RDX during the
regeneration of activated carbon columns used to trap these
explosives.
California Institute of Technology, Environmental
Quality Laboratory, Dr. Glen Cass, P.I.
Analysis by GC-MS of PAHs and hetero-substituted PAHs in urban
aerosol extracts. Both neutral and polar fractions are being
analyzed.
Santa Monica Bay Restoration Project, American
Oceans Campaign, Dr. Michael Stenstrom and Dr. Mel Suffet, P.I.'s
A study to assess the potential biological impacts of
contaminants in urban storm drains to marine life from dry
weather stormwater toxicity analysis. Providing identificaiton
and quantitation of volatile, semi-volatile, semi-volatile and
halogenated organic EPA target analytes at ppb and ppt levels.
Also characterization and identification of non-target analytes
when possible.
Institute of Geophysics and Planetary Physics, Dr.
M. I. Venkatesan, P.I.
Chlorinated hydrocarbons including DDTs and their metabolites and
PHAs are being analyzed in sediment cores from the Santa Monica
and San Pedro basins and from the Santa Monica and San Pedro
basins and from the San Francisco Bay. The data obtained should
help reconstruct historic trends of contaminants in the region.
Chlorinated hydrocarbons are measured at ppt and PAHs at ppb
levels using GC-ECD and GC-MS, respectively.
Institute of Geophysics and Planetary Physics,
Dr. M. I. Venkatesan, P.I.
Fecal sterols are determined from feces of different land mammals
and in sewage effluents discharged into the Santa Monica Bay.
This study is intended to assess the utility of the fecal sterols
as sanitary survey tools. Fecal sterols will be quantitated by GC
and at ppb levels and their identification confired by GC-MS.
