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 Rainwater Herbicide and Organochlorine Concentration

Data

Don Waite

Summary

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

and rainwater samples in order to determine the associated yearly deposition rates. This data set

contains information on the rainwater 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

Rain samples are collected by the dry deposition sampler (dust collector), which consists of a 1-m x

0.5-m, stainless steel (316-grade) tray, with 5-cm-high sides. When rainfall is detected on the

conductivity-type rain detector, the dust collector pump shuts down and two valves operate to divert

rainwater into an exterior, stainless steel container. When the rainfall stops, the rain detector dries with

the help of a built-in heater. The pump restarts and dry deposition sampling is resumed. Rain time is

recorded on an integrated timer. Rain volume is measured separately with a standard rain gauge. The

rainwater is solvent extracted, following published procedures, and the extracts analyzed for target

chemicals. Rain samples were collected as 7-day composite samples.

4. Equipment

4.1 Sensor/Instrument Description

4.1.1 Collection Environment

The data were collected under all environmental conditions.

4.1.2 Source/Platform

Ground.

4.1.3 Source/Platform Mission Objectives

None given.

4.1.4 Key Variables

The key variable is herbicide concentration in composite rainwater samples.

4.1.5 Principles of Operation

Rain was sampled by the dust collector, a sampler designed to collect dry and wet atmospheric

deposits of trace organics. The collecting surface is a 0.5- x 1.0-m2 stainless tray. During dry

conditions, acidified water was constantly circulated across this surface, collecting dry deposits.

Rainfall triggers a sensor, stopping the water flow. Rain falling on the clean collecting tray is diverted

into a stainless steel container that is emptied, manually, at the end of the sampling period (7 days). At

the end of the rainfall, the sampler reverts to dry deposition sampling. Rain duration is recorded by a

timer in the sampler and rain volume by a standard rain gauge.

4.1.6 Sensor/Instrument Measurement Geometry

Dust Collector: A newly designed sampler employing an XAD-2 resin column to extract dry

deposits from a continuously flowing sheet of water and collecting separate rain samples.

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).

Rain samples (500 mL each) were acidified to pH 2 with dilute H2SO4 solution, extracted with

dichloromethane and the extract methylated with diazomethane and subjected to Florisil column prior to

GC-MSD analysis for extracted herbicides (Cessna et al., 1985). A second 500-mL aliquot was

extracted with dichloromethane, subjected to Florisil column, and analyzed for insecticides and

organochlorines by GC-MSD (Cessna et al., 1985).

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

chromatograms 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 and rainwater samples in order to determine the associated yearly deposition rates. This data set

contains information on the rainwater 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.
