Glossary of Terms:

• Concentrations: may be given in ppm = ppmv; mg/m3; mppcf = millions of particles per cubic foot of air as determined from counting an impinger sample; fibers / cm3.
• PEL, Permissable Exposure Limit: OSHA (Occupational Health & Safety Administration). Pre-1989 PELs are enforced by OSHA due to a court ruling that overturned stricter 1989 PELs. The 1989 PELs have some regulatory effect for compounds that did not have PELs prior to 1989.
• REL, Recommended Exposure Limit: NIOSH ( National Institute for Occupational Safety & Health)
• TWA, Time Weighted Average: NIOSH REL designed to be applied in workplace settings for up to 10 hour days (OSHA 8 hour days) during a 40 hour work week
• STEL,:Short Term Exposure Limit: "ST" precedes numerical value. 15 minute TWA that should not be exceeded at any time during a workday. Numerical value is always higher than REL or PEL.
• C REL, Ceiling REL: "C" precedes numerical value. Should not be exceeded at any time. 15 minute TWA is used if instantaneous measurement is not possible. Numerical value is always higher than REL or PEL. Maximum values are specified exceptions to ceiling values. Maximum values are greater than ceiling values, & short duration exceptions to ceiling values are allowed up to the maximum value. For example, Ceiling value not to exceed "a 5 minute maximum peak value in any 2 hours during an 8 hour day.
• (skin): printed after numerical limit; indicates skin absorption is a potential intrusive pathway
• (total): printed after numerical limit; the numerical REL or PEL is for Total Particulate
• (resp): printed after numerical limit; the numerical REL or PEL applies to the 'Respirable Fraction' of the airborne particulate
• carcinogen: printed before or after numerical limit. Indicates that compound is a known or suspected carcinogen.

ORC Bench Studies

• We have performed several bench studies assessing ozonation by-products of natural aquifers simulated using coeval soil borings & groundwater.
• Client specifies conditions, such as water: soil ratios, dose, and chemical constituents of interest. Various ORCs (oxidant release compounds) can be used, for example MnO4-, H2O2, S2O8-2, O3.
• Custom large volume reaction vessels allow multiple fluid withdrawals without significantly effecting experimental water: soil ratios.
• We provide a detailed report, complete with chemical reactions, experimental data, bench & analytical QC & data interpretation.
• MAI is responsible for the data from start to finish. By-products & water quality parameters can exhibit very complex behavior, largely controlled by experimental & analytical technique, & MAI's oversite for this kind of data is crucial. The relationship between ORC dose & contaminant decrease is much simpler & in this context MAI can provide chemical analyses on client provided fluids without experimental oversite.

• CTAS (COBALT THIOCYANATE ACTIVE SUBTANCES)

Preparative Clean Up

• Hydrocarbon fuels & oils, metabolites, biological or food matrix & elemental sulfur are common chromatography interferents. Without clean-up, dilution is required, & the loss of analyte sensitivity may render the data unusable.
• Various types of clean-ups are available from MAI, including GPC (Gel Permeation Chromatography), bench column chromatography, in-a-vial sorption, & chemical treatment.
• Clean-up techniques are best applied to restricted target groups because the specific chemical affinity of the target analytes is the key to the separation process. 'Basket' methods such as EPA 8270 have no useful clean-up procedure whereas restricted chemical groups such as PCBs, PNAs and dioxins have very effective clean-ups.
• GPC (EPA 3660) is applied to matrices containing biological (cell material, peptides, proteins, triglycerides, fats/oils) interferents and/or elemental sulfur & combines size exclusion & affinity chromatography. It is not sufficient by itself to clean up natural matrices but can be a useful starting point, especially for time integrated SPMD samples.
• Bench column chromatography (EPA 3600) primarily uses silica gel, alumina or florisil as sorbents in affinity chromatography & requires skilled chemists, well developed techniques & accompanying QC data for effective use.
• Chemical treatments, such as water washing to separate water soluble from water-insoluble compounds, or acid-permanganate clean-up of PCBs in oils, are generally less effective than bench column chromatography but are inexpensive & have situational applications.
• MAI can perform customer specifed clean-up procedures or develop custom clean-up procedures upon request.
