PESTICIDE RESIDUES IN FOOD - 1982
Sponsored jointly by FAO and WHO
EVALUATIONS 1982
Data and recommendations of the joint meeting

BROMOPHOS
Explanation
Bromophos was evaluated in 1972, 1975 and 1977 (FAO/WHO 1973,
1976, 1978)1/. Although there were no specific requirements for
further work due in 1982, additional information became available on
residues in vegetables, field crops, pome fruit, stone fruit and
berries. These data are reviewed for confirming or adjusting previous
recommendations or for making new recommendations on additional
commodities.
RESIDUES IN FOOD AND THEIR EVALUATION
RESIDUES RESULTING FROM SUPERVISED TRIALS
In Crops
Data were received on the results of supervised trials on a wide
variety of crops carried out by the manufacturer in numerous field
locations throughout the Federal Republic of Germany (Celamerck 1982).
This information is summarized in Tables 1-8.
Information on residues in oats, barley, wheat, oilseed rape and
sugarbeets is summarized in Table 1. Maximum residues at 7 days
preharvest were 1.09 mg/kg for barley, 0.77 mg/kg for oats, 0.95 mg/kg
for wheat, <0.02 mg/kg (at 70 days) for oilseed rape, <0.02 mg/kg
for sugarbeet roots and 0.16 mg/kg for sugarbeet leaves. The data on
oats, barley and wheat show that residues from field treatment of
these crops would not exceed the existing recommended level for new
grain, which is based on the levels found in storage uses of bromophos
on grains. Both sugarbeet roots and leaves can be included in the
existing recommendation of 0.5 mg/kg. No change in recommendation is
indicated by the data for oilseed rape.

Extensive trials on apples, presented in Table 2, show that
residues as high as 4.47 mg/kg could be found even at 14 days
preharvest and indicate a need to increase the recommended limit from
2 mg/kg to 5 mg/kg.
The data on cherries, plums and peaches, shown in Table 3, reveal
maximum levels of 0.63 mg/kg on cherries, 2.90 mg/kg on plums and
0.52 mg/kg on peaches at preharvest intervals of 7, 14 and 7 days,
respectively. These data support an increase in recommended levels for
cherries and peaches from 0.5 to 1 mg/kg and for plums from 1 to
5 mg/kg.
Additional data on red currants and new data on raspberries are
presented in Table 4. The maximum level of 0.7 mg/kg at 7 days
preharvest for red currants supports the existing recommendation of
1 mg/kg. A maximum level of 0.12 mg/kg at 7 days preharvest for
raspberries show that the existing level of 1 mg/kg for blackberries
would not be exceeded and that a new combined recommendation can be
accommodated.
The additional data on residues on lettuce and spinach, in
Table 5, indicate that maximum levels of 1.45 mg/kg for lettuce and
1.89 mg/kg for spinach could be reached at 7 days preharvest. These
figures indicate a need to increase the recommended maximum residue
level for both commodities to 2 mg/kg.
Additional residue data on cabbage, savoy cabbage, cauliflower,
kohlrabi and onions and new data on kale are summarized in Table 6.
Maximum residues of <0.03 mg/kg on cabbage (at 41-48 days
preharvest), 0.03 mg/kg on savoy cabbage at 7 days preharvest, and
0.09 mg/kg on cauliflower at 7 days preharvest indicate that the
previously recommended levels of 0.1, 1 and 0.1 mg/kg respectively
would not be exceeded. The additional data on kohlrabi show a maximum
level of 0.02 mg/kg at 44 days preharvest, which supports the previous
recommendation limit of 0.1 mg/kg. Additional data on residues on
onions at 57 days preharvest reached a level of 0.22 mg/kg, requiring
an increase to 0.5 mg/kg from the existing recommended limit of
0.1 mg/kg. New data on kale show that a maximum residue of 0.22 mg/kg
was possible at 21 days preharvest arising from 3 applications of 2%
dust.
Additional data on residues on carrots and radishes are shown in
Table 7, where maximum values of 1.40 mg/kg for carrots and 1.39 mg/kg
for radishes are found at 42 and 21 days preharvest respectively.
These data require that the recommended level for carrots be increased
from 1 to 2 mg/kg while that for radishes (2 mg/kg) can remain
unchanged.
Table 8 summarizes additional residue data on cucumbers, bush
beans and peas and new data on tomatoes. At 7 days preharvest, the
maximum level found were 0.11 mg/kg on cucumbers, 0.04 mg/kg on beans
and <0.01 on peas (without pods). For peas (whole hulls) the maximum
at 8 days was 0.12 mg/kg. From an examination of all of the tabular
data on cucumbers, beans and peas it appears unlikely that the
existing recommendation of 0.1 mg/kg would be exceeded for these
commodities. The residue data on tomatoes show that a maximum level of
0.43 mg/kg was reached on one trial at 4 days preharvest, therefore a
new recommendation for tomatoes of 0.05 mg/kg can be proposed.
From Tables 1 and 8, residue data on oat, barley and pea straws
are available, which reach maximum levels of 0.08 mg/kg on oat straw,
0.06 mg/kg on barley straw and 0.44 mg/kg on pea straw, supporting a
new recommendation for a maximum residue level of 0.5 mg/kg for straw
(barley, oat, pea).
NATIONAL MAXIMUM RESIDUE LIMITS
Information on the current national tolerances in effect in the
Federal Republic of Germany was available (Celamerck 1982) and is
presented in Table 9.
Table 9. Maximum Residue Limits for Bromophos in the Federal
Republic of Germany
MRL (mg/kg) Commodities
2.0 Leafy and other stem vegetables (except
brassicas), pome fruit, plums, root vegetables,
citrus fruits.
1.0 Berries, cereals (except maize), brassica,
other stone fruit.
0.5 Other vegetables
0.2 Maize, oilseed rape, turnip rape
0.1 Other edible crops.
APPRAISAL
A substantial amount of new information was made available to the
Meeting on residues resulting from supervised trials in the Federal
Republic of Germany on field crops, apples, stone fruit, berries and
vegetables. Evaluation of these data resulted in the need to increase
the recommended limits for apples, plums, carrots, lettuce, spinach,
cherries, peaches and onions; supported existing limits for sugarbeet
roots, wheat, rape seed and rape seed oil, red currants, cabbage,
savoy cabbage, cauliflower, kohlrabi, radish, cucumbers, beans and
peas; and resulted in the addition of new recommendations for barley
and oats (included in the cereal grains group), raspberries, kale,
sugarbeet leaves, tomatoes and straw (barley, oat, pea).
Since the previous recommended limit for raw grain (now changed
to cereal grains) was based on the higher residue levels that accrue
from storage uses of bromophos, the contribution from field
applications to barley, oats and pea straw, combined with the new
recommendations for sugar-beat roots and leaves and the existing
limits for wheat bran and apples, reveals an increasing use pattern
affecting animal feed, forage and fodder. The rather scanty data on
which existing meat (of sheep) and milk limits are based should be
supported or supplemented with new information on meat (except sheep)
and milk residues likely to arise from feed sources. There is also an
indication from national tolerances reported to the Meeting that
bromophos is used on citrus in some locations, although no data are
available from which to make recommendations.
The Meeting agreed with the need to increase the recommendation
for milk from 0.02 to 0.05 mg/kg (at or about the limit of
determination) in order to reflect analytical limitations more
accurately.
RECOMMENDATIONS
The following recommended maximum residue limits are in addition
to or replace those previously recommended. The preharvest intervals
on which these recommendations are based are discussed in the
addendum. The limits refer to bromophos only.
Commodity Limit (mg/kg)
Cereal grains 10
Apples 5 (increased from 2)
Plums 5 (increased from 1)
Carrots, spinach 2 (increased from 1)
Lettuce 2 (increased from 0.5)
Cherries, peaches 1 (increased from 0.5)
Raspberries 1
Onions 0.5 (increased from 0.1)
Sugarbeet leaves 0.5
Kale 0.5
Tomatoes 0.5
Straw (barley, oats, pea) 0.5
Milk 0.05*
* at or about the limit of determination
FURTHER WORK OR INFORMATION
Desirable
1. Supervised trial data on residues in meat and milk arising from
the use of treated feed, forages and fodder.
2. Information from supervised trials on residues in citrus arising
from approved uses.
