INTRODUCTION
The National Soils Monitoring Program is an integral part
of the National Pesticide Monitoring Program (NPMP). The
NPMP was initiated as a result 0 f the recommendations made by
the President’s Science Advisory Committee report of 1964,
entitled “Use of Pesticides”. The committee recommended that
the appropriate Federal agencies “develop a continuing network
to monitor residue levels in air, water, soil, man, wildlife,
and fish” (1}.
The objectives of the NPMP are to determine levels and
trends of pesticides in the various components of the environ-
ment (2). This will result in the establishment of baseline
or background levels of pesticide residues which in turn can
be used as a basis for comparison of subsequently identified
pesticide residue levels in an environmental component.
The NPMP (2) lists five bases for concern to be used in
evaluating pesticide residue levels. They are:
1. Any concentration of a pesticide known to be poten-
tially harmful
2. Increasing trends
3. Exceeding standards (where they exist)
4. Recognition of adverse effects on humans
5. Erratic variability 1
1 A statistically oriented observation that is potentially
conunon to each stratum sampled.

-------
3.
The results of this study meet the first objective of the
NPMP by establishing a baseline of pesticide residues in
cropland soils at a particular point in time. Subsequent soil
sampling will enable us to meet the second objective.
The present data and all future data will be reviewed
bearing in mind the five bases of concern outlined above.
SAMPLING PROCEDURES & METHODS
In general, techniques involved in this study were the
same as those employed by Wiersma etal. (3).
In FY 1969 cropland soil was sampled in all states except
Alaska, Hawaii, Kansas, Minnesota, Montana, Oregon and Texas.
Noncropland was sampled in Arizona, Georgia, Idaho, Iowa, Maine,
Maryland, Nebraska, Virginia, Washington, West Virginia and
Wyoming. Samples collected in the year of the study included
both soil and crop. Only those crops that were mature and/or
ready for harvest at time of collection were sampled.
ANALYTICAL PROCEDURES
ORGANOCHLORINE AND ORGANOPHOSPI-IOROUS COMPOUNDS
1. Preparation of sample
A subsample of 300 g wet weight of soil was placed in
a 2-quart fruit jar with 600 ml of 3:1 hexane-isopropanol
solvent. The jars were sealed and rotated for 4 hours. After
rotation, the soil was allowed to settle and 200 ml of the
extract solution was filtered into a 500 ml separatory funnel.

-------
4.
Isopropanol was removed with two washings of distilled water.
The remaining solution was then filtered through a funnel
containing glass wool and anhydrous sodium sulfate (Na 2 SO 4 ).
Further cleanup was normally not required before analysis.
2. Gas-liquid chromatography
Analyses were performed on gas chromatographs equipped
with tritium foil electron affinity detectors for organochlorine
compounds and thermionic or flame photometric detectors for
organophosphorous compounds. A dual column system employing
polar and nonpolar columns was utilized to identify and confirm
pesticides. Instrument parameters were as follows:
(a) Column: glass 6 mm o.d. x 4 m i.d., 183 cm long,
packed with one of the following:
3% DC—200 on 100/120 mesh Gas-Chrom Q
9% QF-l on 100/120 mesh Gas-Chrom Q
(b) Carrier gas: 5% methane-argon at a flow rate of
8 mi/mm.
(c) Temperature:
Detector: 200°C
Injection Port: 250°C
Column QF-l: 166°C
Column DC-200: 170-175°C

-------
5.
When necessary, confirmation of residues was made by thin-
layer chromatography, or p—values. The lower limit of detection
is 0.01 ppm. The data are corrected for recovery. The average
recovery rate for all pesticides was 100% plus or minus 10%.
All residue data are also corrected to dry weight basis.
ATRAZINE
1. Preparation of sample
After a 4-hour Soxhiet extraction of a 50 g subsample of
soil with 25 ml of water and 300 ml of methanol, the sample
extract was transferred to a 1—liter separatory funnel and 200 ml
of water added.
The sample extract was partitioned three times with a
portion of 150 ml of freon 113 for each partitioning. The freon
113 fractions were combined and concentrated to incipient dryness.
The sample was then dissolved in hexane, adjusted to a 5 ml volume
and injected into a gas—liquid chromatograph.
2. Gas—liquid chromatography
Thermionic flame detector with rubidium sulfate coating
on a helix coil was used. Instrument parameters were as follows:
(a) Column: glass 6 nm o.d. x 4 m i.d., 183 cm long,
packed with 3% Versamid 900 on 100/1 20 mesh Gas-Chrom Q
(b) Carrier gas: helium
(c) Detector fuel gas: oxygen (200-300 mi/mm.),
hydrogen (20-30 ml/rnin.)

-------
6.
(d) Temperature:
Detector: 240°C
Injection Port: 240°C
Column: 240°C
Confirmation was made using a DC-200 column at 180°C and a
Coulson detector (reductive mode) at the following temperature
settings:
Pyrolysis tube: 850 0 C
Transfer line: 220°C
Block: 220°C
2,4-D
Analyses were made following the procedure developed by
Woodham (4). The analytical method involved a diethyl ether
extraction of acidified soil, an alkali wash to remove
interfering substances, and an esterification procedure
using 10% boron trichioride in 2-chioroethanol reagent. The
2-chioroethyl ester of 2,4-D was then analyzed by gas chroma-
tography..
ARSEN IC
Arsenic was determined by atomic absorption spectropho-
tometry. The soil sample was first extracted with 9.6N
hydrochloric acid (HCL) and reduced to trivalent arsenic with
stannous chloride. The trivalent arsenic was partitioned
from HCL solution to benzene, then further partitioned into
water for the absorption measurement. A Perkin-Elmer Model

-------
7.
303 instrument was used, absorbance being measured with an
0
arsenic lamp at 1972 A with argon as an aspirant to an air-
hydrogen flame. Recovery value for arsenic averaged 50%.
RESULTS
The data in this report are for soils only, and are
presented in the tables for all states sampled in the study;
The data are further divided between cropland and noncropland.
Caution should be exercised when interpreting the arithmetic
means presented in the tables. Pesticide residue data are not
normally distributed and the arithmetic means for pesticide
residues tend to be greater than the corresponding median.
Therefore, they cannot be considered an indication of the central
tendency of the data. Information accompanying the arithmetic
means in this report such as the percent of occurrence, range
and number of observations can aid in evaluating the arithmetic
mean.
RESIDUES-ALL STATES
Soil residues are summarized in a variety of ways. They
include arithmetic means, the percent of times a detectable
residue was found and the range of detected residues. The
residue summaries for cropland for all 43 states are presented
in Table 1. The means given are arithmetic. The lower limit
of sensitivity, as stated earlier, is 0.01 ppm, and this was used

-------
8.
to calculate the percent of times a detectable residue was found.
DDTR is a compilation of all the members of the DDT group.
Elemental arsenic residues were found most frequently, with
a percent of occurrence of 99.3 and a mean level of 6.4 ppm.
It is probable that the majority of this arsenic was from natural
sources, although cultural sources cannot be ruled out at this
time.
The most widely distributed pesticide was dieldrin, with
27.8% of the samples having detectable residues. It was followed
clOsely by the total DDT residues (DDTR). Aldrin was found in
10.9% of the samples and chiordane in 8.7% of the samples.
The highest mean residue was DDTR, with 0.31 ppm found in
cropland soils. With the exception of individual members of the
DOT group, the other pesticides had average residues ranging from
below the limits of sensitivity to 0.07 ppm.
The figures for atrazine, 2,4-0 and the organophosphates
(Table 1) are not truly comparable with those generated for the
chlorinated hydrocarbons or arsenic, because analyses for atrazine
and 2,4-D were made only when the use records indicated they had
been applied. Analyses for organophosphates were made on only 66
of the 1729 samples.
With this in mind, note that ethyl parathion was detected
10.6% of the time, with a mean residue of 0.06 ppm. Malathion
and diazinon were each detected 3.0% of the time with mean residue
levels from below the limits of sensitivity to 0.01 ppm.

-------
9.
One-hundred--eighty—eight chemical analyses were made for 2,4 —D
and the other chioropherioxy herbicides. 2,4—0 was the only one
detected, and it was found in 1.6% of the samples with a mean
pesticide level less than 0.01 ppm. Atrazine was detected in
14.1% of the samples with a mean residue level of 0.01 ppm.
This herbicide had the highest mean residue of the herbicides
detected. Trifluralin was detected in 3.5% of the samples with
a mean residue level of less than 0.01 ppm.
The residues found in noncropland soils for the 11 previously
listed states are presented in Table 2. The mean arsenic residue
was 5.0 ppm occurring in 98.5% of the samples. DDTR was detected
in 16.1% of the noncropland soils. ODTR residues ranged from
0.01 to 0.62 ppm with a mean residue level of 0.01 ppm. With the
exception of members of the DOT group, dieldrin was the most
widely distributed pesticide, occurring in 4.0% of the samples witri
residues ranging between 0.01 to 0.09 ppm and a mean residue level
less than the detectable limits of the chemical assay.
It is possible to estimate the total amount of certain pesticides
present in cropland soil. This has been done for dieldrin, aidrin
and DDTR, three of the most commonly occurring pesticide residues. A
weighted mean was calculated using the individual state averages.
The data were transformed using a log (X+.Ol) transformation and the
geometric mean and 95% confidence intervals were calculated.

-------
10.
Since soil cores were 3 inches deep, and an acre of soil
with this depth weighs approximately one million pounds, residue
figures in parts per million can be directly converted to pounds
per acre. Total acres in crops were obtained from “Agricultural
Statistics 1970” (5). Figures for acreage used to estimate the
amounts of pesticides shown in Table 3 were for the 48 coterminous
states and included all cropland used for crops or cropland idle
or in cover crops; but did not include cropland used only for
pasture since this category was not included under croplarid in
the original sampling design. The total estimated acreage was
approximately 387 million acres.
The use records collected in this study do not lend themselves
readily to a statistical estimate of the total tons of DDT applied;
therefore, the use records from the Economic Research Service (ERS) (6)
are used for comparison purposes. ERS estimated that farmers used
approximately 14,950 tons of DOT in 1966. In our study, 10,565 tons
of DDTR were detected in soil. This is approximately 71% of the total
used in 1966. The amount of DOT actually used in 1968 was probably
less than that used in 1966, since there has been a general decline
in its use. ERS also estimated that 7,742 tons of aldrin/dieldrin
were used by farmers in 1966. In 1968, 4,180 tons of dieldrin and
3,889 tons of aldrin were detected as residues in cropland soil. The
combined aldrin/dieldrin residues were 8,069 tons or 104% of the
total amount applied in 1966.

-------
11.
Clearly considerable amounts of DDTR, aidrin and dieldrin
are present in the upper 3 inches of cropland soil. The fate
and impact of these residues cannot be evaluated at this time.
RESIDUES—INDIVIDUAL STATES
The pesticide residue summaries for cropland by individual
states are given in Table 4 and similar results for noncropland
in Table 5. It would be impractical to att pt to comment on
the results for each state. Therefore, in order to facilitate
summarizing the data, Figures 1, 2 and 3 are presented. These
are for three of the most commonly occurring residues, arsenic,
DDTR and dieldrin. Means for each pesticide in each state were
calculated, and distribution of these averages are indicated on
the corresponding figures.
The class intervals for the keys accompanying each figure
were obtained in the following manner. The range of residu for
the nation was obtained and the highest value was converted to a
logarithm. This value was then divided by the number of desired
classes. The resulting intervals were added to obtain the class
boundaries which in turn were converted to the untransformed
dimensions. Essentially, this took advantage of the fact that
most residue data are logarithmically distributed.

-------
12.
Distribution of arsenic residues across the United States is
presented in Figure 1. The highest residue levels were found in
the New England states 1 , Arkansas, Kentucky, New York, North Dakota,
Ohio and Pennsylvania. These states and groups of states had mean
residues of arsenic greater than 8.4 ppm. The remaining residues
were distributed primarily in the 2.0 to 8.4 ppm range, with
Wyoming and Florida having less than 2.0 ppm. Those states left
blank were not sampled.
The distribution of DDT residues (DDTR) is shown in Figure 2.
Once again, the key indicates the range of residues for each of
the class intervals. A similar map for dieldrin residues is presented
in Figure 3.
A comparison of the mean residues, the percent of times detected
and the range for the 12 states with the highest arsenic residues
are shown in Table 6.
The five states with the highest DDTR residues are presented
in Table 7. Although Michigan has a mean residue of 2.09 ppm and
a range of 0.01 to 78.36 ppm, only 23.5% of the samples had
detectable residues, indicating that the residues were not widely
distributed. Mississippi had a mean residue of 2.06 ppm with 89.7%
of its sites having detectable rc sidues. Also, the range was narrower,
1 Includes Connecticut, Maine, Massachusetts, New Hampshire, Rhode
Island and Vermont.

-------
13.
running between 0.03 to 13.14 ppm. This indicates a much wider
distribution of pesticide residues in Mississippi than in Michigan.
The seven states with the highest dieldrin residues are shown
in Table 8. The highest mean residue, 0.11 ppm, was found in
Illinois, with 61.3% of the sites having detectable residues. In
general, the other six states tended to have mean residues approxi-
mating one another and ranging between 0.06 to 0.08 ppm.
PESTICIDE USE RECORDS
When soil samples were collected, an attempt was made to
determine what pesticides had been used on the sites for the year
of sampling. The sunii ary tables for the use records show the
percert of times a pesticide was used, the average application
rate expressed in pounds per acre of the active ingredients, and
the average amount. This last figure was determined by dividing
the total amount of active ingredient of a pesticide used by the
total number of sites surveyed.
Table 9 shows 130 different pesticides reported to have been
used in the year of sampling. Those most comonly used were
atrazine, captan, 2,4-D, malathion and methylmercury dicyandiamide.
DDT was used on 3.44% of the sites, aidrin on 4.16% of the sites
and dfeldrin on 1.19% of the sites.
On noricroplarid sites 2,4-0, malathion and mirex were reported
to have been used (Table 10). However, these should not be considered

-------
14.
the only pesticides used on noncropland sites. In general, records
kept for treatment of noncropland sites are less accurate than
those kept for cropland. The breakdown of pesticide usage by
individual states for cropland and noncropland, respectively, are
shown in Tables 11 and 12.
Because of the number of states and pesticides presented in
Tables 11 and 12, it is difficult to make all possible oomparisons
between the use patterns indicated and the detected residues shown
in Tables 4 and 5. Therefore, we have restricted our comparison
to those states having the highest residues as shown in Figures 1,
2 and 3.
Table 13 compares those states having the highest arsenic
residues with the average amount applied per site and the percent
of sites which reported using an arsenic compound. There does not
seen to be a relationship between the amount of arsenic applied
and the amount detected in the soil. Arkansas, Kentucky, North
Dakota and Ohio reportedly used no arsenic compounds, whereas New
England, New York and Pennsylvania reported using sodium arsenite
and lead arsenate. The application rates were below the detected
levels, and the percent of times used was below the percent of
times residues were detected. It also must be considered that the
application rates were for the active ingredients of sodium arsenite

-------
15.
and lead arsenate, and not for elemental arsenic alone. A fair
assumption uld be that most arsenic residues detected in
cropland soils probably resulted from natural levels of arsenic.
A similar comparison for the five states with the highest
DDTR residues is found in Table 14. In this case, there is not
the confusing factor of natural levels of DDTR as there is with
arsenic. We can assume that DDTR detected in the soil resulted
from the activities of man, either in the year of sampling or in
previous years. Mote that 0 f the five states listed, California,
Michigan, Mississippi and South Carolina have application rates
less than the mean amount detected in the soil. It is also
interesting to compare the percent of sites which reported using
technical 001 in the year of sampling. The percent of times
residues were detected was approximately three or more times
greater than the percent of times farmers reported using DOT.
Table 15 shows the seven states with the highest dieldrin
residues. In most cases, the average amount of aldrin/dieldrin
applied approximated the mean residue of dieldrin detected in
the soil, but the percent of times which dieldrin or aldrin were
reported used was always considerably less than the percent of
times detected. This wider distribution of dieldrin residues,
when compared to use records for the year of sampling, probably
indicates residues from previous years.

-------
16.
PESTICIDE FREQUENCY DISTRIBUTION
The statistics discussed so far about residue data, namely
the mean, the range and the percent of times that the residues
were detected, do not describe their distribution. One way to
describe this distribution is through the use of probit analysis.
The residue levels were ranked from lowest to highest, accumulated,
and the percentages computed. The residues were transformed to
logarithms, the percentages to probits, and the relationship between
the logarithms of the residues and the probits of the accumulated
percentages was calculated by regression analysis. The computer
program used was that of Daum (8). The theory and techniques as
applied in the cited reference were modified slightly.
The distribution for the individual pesticides in soil for
each state, and the residue levels along with the upper and lower
95% fiducial limits are presented in Table 16. An example will
show how the tables are read. In the state of Alabama, the 50
percentile point for arsenic was 4.09 ppm. Thus, 50% of the sites
had residues less than 4.09 ppm. A similar interpretation is
applicable to any of the percentile levels found in Table 16.
The upper and the lower fiducial limits of the residues establish
the 95% confidence interval about the residue value for that
percentile. It should be noted that the mean for a particular
state, is not the same as the 50 percentile point from the

-------
17.
frequency distribution. For example, the mean level of arsenic
for Alabama was 6.1 ppm, while the frequency distribution gives
4.09 p ii for the 50 percentile point. In other words, approximately
70% of the sites had residues less than the arithmetic mean. This
is an example of the fact that residue data are not normally distributed
and the mean and median are not identical.
Not all pesticides are shown for all states. A cut—off point
of six or more pairs of observations was used to eliminate situations
where there were too few observations to calculate a reliable
distribution.
CROPPING REGIONS ANALYSIS
The data were grouped by counties into various cropping regions,
and these are shown in Tables l7 and 18. The basis for the boundaries
of the various cropping areas was from a major land use map of the
United States compiled by F. J. Marschner, of the U.S. Department
of Agriculture, Bureau of Agricultural Economics, 1950. No effort
was made to make a land use division within counties. This
resulted in a good definition of the larger land use areas such as
the corn belt and cotton—growing areas. The land in the United
States was grouped into several major land use areas--corn, cotton,
fruit, general farming, hay, small grain, and vegetables. In some
cases, two areas overlapped. Irrigated land was determined from
information obtained at the time of sample collection in this
study.

-------
18.
It is of interest to make a few individual comparisons
between the cropping regions and the national means. For
example, note that in the corn region, aidrin occurs 23.5%
of the time (Table 18) with a mean residue level of 0.05 ppm
(Table 17). However, nationally, aidrin only occurs 10.9% of
the time with a mean level of 0.02 ppm (Table 1), an indication
of the heavier use of aidrin in the corn region. But, in the
corn region, the mean residue level of DDT is 0.14 ppm which is
well below the national mean of 0.31 ppm. Atrazine in the corn
region has a mean residue level of 0.02 ppm with 14.5% of sites
having detectable residues. This approximates closely the figure
presented in Table 1 for atrazine in all the states.
The vegetable and fruit cropping region has the highest
level of DDTR, over two times higher than the next highest cropping
region and over six times higher than the national mean for DDTR.
This might result from a high use of DOT in various orchard
operations. The next highest residue is found in the cotton and
vegetable region, with approximately equal amounts detected
between them. The rest of the amounts of DOT in the cotton and
general farming, general farming, hay and general farming, and
irrigated land are within close proximity to one another. The
two areas with the least amount of DDT in the soil are the corn
and small grains cropping regions.

-------
19.
The corn, vegetable, and vegetable and fruit cropping regions
have the heaviest residues of dieldrin. Residues of dieldrin in
the other cropping regions are either equal to or below the mean
residues detected for all states (Table 1).
The highest toxaphene residues were found in the cotton cropping
region. The cotton and general farming, and general farming cropping
regions have residue levels of about half those detected in the
cotton cropping region.
