The NASA STI Program Office ... in Profile

Since its founding, NASA has been dedicated to

the advancement of aeronautics and space

science. The NASA Scientific and Technical

Information (STI) Program Office plays a key

part in helping NASA maintain this important

role.

The NASA STI Program Office is operated by

Langley Research Center, the lead center for

NASA's scientific and technical information. The

NASA STI Program Office provides access to

the NASA STI Database, the largest collection of

aeronautical and space science STI in the world.

The Program Office is also NASA's institutional

mechanism for disseminating the results of its

research and development activities. These

results are published by NASA in the NASA STI

Report Series, which includes the following

report types:

• TECHNICAL PUBLICATION. Reports of

completed research or a major significant

phase of research that present the results of

NASA programs and include extensive data or

theoretical analysis. Includes compilations of

significant scientific and technical data and

information deemed to be of continuing

reference value. NASA's counterpart of

peer-reviewed formal professional papers but

has less stringent limitations on manuscript

length and extent of graphic presentations.

• TECHNICAL MEMORANDUM. Scientific

and technical findings that are preliminary or

of specialized interest, e.g., quick release

reports, working papers, and bibliographies

that contain minimal annotation. Does not

contain extensive analysis.

• CONTRACTOR REPORT. Scientific and

technical findings by NASA-sponsored

contractors and grantees.

CONFERENCE PUBLICATION. Collected

papers from scientific and technical

conferences, symposia, seminars, or other

meetings sponsored or cosponsored by NASA.

SPECIAL PUBLICATION. Scientific, technical, or historical information from NASA

programs, projects, and mission, often concerned with subjects having substantial public

interest.

TECHNICAL TRANSLATION.

English-language translations of foreign scientific and technical material pertinent to NASA's

mission.

Specialized services that complement the STI

Program Office's diverse offerings include creating custom thesauri, building customized databases, organizing and publishing research results...

even providing videos.

BOREAS TGB-7 Ambient Air Herbicide and Organochlorine

Concentration Data

Don Waite

Summary

The BOREAS TGB-7 team measured the concentration and flux of several agricultural pesticides in

air, rainwater, and dry deposition samples in order to determine the associated yearly deposition rates.

This data set contains information on the ambient air concentration of seven herbicides

[2,4-dichlorophenoxyacidic_acid (2,4-D), bromoxynil, dicamb, 2-methyl-4-chlorophenoxyacetic acid

(MCPA), triallate, trifluralin, and diclop-methyl] known to appear in the atmosphere of the Canadian

prairies. Also, the concentration of three herbicides (atrazine, alachlor, and metolachlor), two groups

of insecticides (lindane and breakdown products and dichloro-diphenyl-trichloroethane (DDT) and

breakdown products), and several polychlorinated biphenyls commonly used in the central United

States was measured. All of these chemicals are reported, in the literature, to be transported in the

atmosphere. Many have been reported to occur in boreal and arctic food chains. The sampling was

carried out from 16-Jun to 13-Aug-1993 and 04-May to 20-Ju1-1994 at the BOREAS site in the Prince

Albert National Park (Waskesiu). The data are stored in tabular ASCII files.

3. Theory of Measurements

Each sample consisted of approximately 2100 m3 of air aspirated by a high-volume sampler (Model

PS- 1, General Metal Works, Village of Cleves, OH). The sampling unit consisted of a

102-mm-diameter borosilicate filter in front of a composite polyurethane foam (PUF)/XAD-2 resin

plug (Cessna et al., 1997). The sampler operated continuously for 7 days for each sample.

5. Data Acquisition Methods

The herbicide analyses were carried out at the Agriculture and Agri-Food Canada Research Station at

Regina, Saskatchewan, whereas insecticide and organochlorine analysis was carried out by the

Environment Canada laboratory in Edmonton, Alberta. All residues were quantified and confirmed

using a Hewlett-Packard gas chromatograph equipped with a mass selective detector (GC-MSD).

Extraction of PUF/XAD-2 Sampling Units:

On alternate weeks, the PUF/XAD-2 sampling units were extracted for herbicide or for insecticide

and organochlorine content. For herbicide analysis, the sampling unit was Soxhlet extracted for 8 h

with acetone (Grover et al., 1994). The acetone extract was concentrated to N0.5 mL using a rotary

evaporator (water bath 30 °C) and then methylated with ethereal diazomethane. The methylated extract

was subjected to Florisil column cleanup prior to analysis by GC-MSD. For insecticide and

organochlorine analysis, the PUF sampling unit was Soxhlet extracted for 12 h with dichloromethane.

The extract was concentrated using a rotary evaporator and then subjected to Florisil column cleanup

prior to analysis by GC-MSD.

Residue Analysis and Confirmation:

The Hewlett-Packard GC-MSD system and operating conditions used for herbicide residue

analysis have been described previously (Cessna et al., 1997). A similar GC-MSD system was used

for insecticide and organochlorine analysis; however, the column employed was a 30 m x 0.25 mm

I.D. Rtx-5 column (0.25-pro film thickness). For operation of the GC, helium was used as the carrier

gas and the temperature program was initially held at 80 °C for 1 minute and then ramped to 200 °C at

15 °C/rain; then it was held at 200 °C for 5 minutes, increased at 8 °C/rain to 300 °C, and held for 10

minutes. A split/splitless injector was used in the splitless mode. Injection port and transfer line

temperatures were 270 °C and 280 °C, respectively.

Depending on the compound, from two to four ions were monitored on the MSD. The presence of

each compound was considered to be confirmed if all ions monitored were present, a peak appeared at

the retention time (+ 0.02 rain) obtained for a standard solution of the pesticide in the reconstructed

chromatiograms of all ions, and the peak area ratio was within 30% of the ratio obtained using a

standard solution of the pesticide.

13. ABSTRACT (Maximum 200 words)

The BOREAS TGB-7 team measured the concentration and flux of several agricultural pesticides in

air, rainwater, and dry deposition samples in order to determine the associated yearly deposition rates.

This data set contains information on the ambient air concentration of seven herbicides [2,4-

dichlorophenoxyacidic_acid (2,4-D), bromoxynil, dicamb, 2-methyl-4-chlorophenoxyacetic acid

(MCPA), triallate, trifluralin, and diclop-methyl] known to appear in the atmosphere of the Canadian

prairies. Also, the concentration of three herbicides (atrazine, alachlor, and metolachlor), two groups

of insecticides (lindane and breakdown products and dichloro-diphenyl-trichloroethane (DDT) and

breakdown products), and several polychlorinated biphenyls commonly used in the central United

States was measured. All of these chemicals are reported, in the literature, to be transported in the

atmosphere. Many have been reported to occur in boreal and arctic food chains. The sampling was

carried out from 16-Jun to 13-Aug-1993 and 04-May to 20-Ju1-1994 at the BOREAS site in the Prince

Albert National Park (Waskesiu). The data are stored in tabular ASCII files.
