3.1 Pesticide residue test unit
The experimental space of the pesticide residue test unit should have the following conditions: (1) Instruments, equipment and environmental facilities that meet the technical requirements of residue analysis; (2) Residue analysis should be carried out in accordance with the operating procedures. 3.2 Pesticide residue test personnel
Pesticide residue test requires professional and technical personnel, with professional knowledge and experience in pesticide residue test, master the relevant regulations and skills of pesticide residue test:
3.3 Background information of residue test
The background information of the test includes: the physical and chemical properties of registered pesticide active ingredients and their dosage forms, the crops and control targets used, the appropriate period and frequency of use, the recommended safe interval, the residue analysis method and the existing residue environmental evaluation data, etc., and the common name of the pesticide (in Chinese and English) on the pesticide product label shall be recorded. Name (Chinese, English meaning), precautions and manufacturer (public), product batch number, etc. 3.4 Design principles of residue test
3.4.1 According to the method of use of the pesticide product, it is expected to obtain the maximum residue under the standard conditions. 3.4.2 Unlike the efficacy test, the existence or non-existence of the control target does not affect the implementation of the residue test plan: 4 Design of field test
4.1 Number of repetitions of field test
Determine the number of repetitions of field test according to the quality of the residue test material and the requirements of pesticide registration information. 4.2 Test site
4.2.1 Representative sites should be selected to cover the main planting areas. 4.2.2 The number of test sites depends on the application of registered pesticides, crop characteristics and farming methods. It is not necessary to set up a test site for the same ecological and climatic planting area. However, attention should be paid to the fact that the test data is representative enough and the test site should comply with the requirements of the "Registration Requirements". There should be no less than two planting areas with different ecological and climatic conditions. 4.2.3 Before the test, the soil type, crop, pesticide application industry, climate and other conditions of the test site should be carefully measured. The plots with uniform crop growth and flat terrain should be selected. Before and during the test site planning, the company's pesticides should not be neglected to avoid interference with the analysis and testing of the test pesticides. 4.3 Test Crops
Determine the test crops in accordance with the "Requirements for Pesticide Registration Information". - Use: Pesticides for multiple crops. ...: Select from crops! 1. Carry out residue test on the main varieties of 2 or more major crops: When the dosage and method of use are similar, the residue data on the major crops in the group can be considered to be used for other crops at the same time. 4.4 Experimental plot
Grain crops shall not be less than 30m, leafy vegetables shall not be less than 15㎡, and trees shall not be less than 2 carbon. More than 3 complex plots shall be set up in each plot, and protected rows or fields shall be set up between the plots: The experimental plots can be arranged from low to high according to the dosage of the pesticide. Avoid cross contamination: Pay attention to the water flow and wind when irrigating. Do not irrigate during watering: The test must have a control plot, and set up an effective isolation zone with the treatment area to avoid drift, volatilization and leaching pollution: When doing fumigation, fog and smoke tests in protected areas (warm slaughter, shed, warehouse), different dosage treatments shall be selected separately: 4.5 Application methods and equipment
VY/T 788—2004
The pesticide application method and equipment for the residue test should adopt the standard pesticide application method and equipment. Before application, the pesticide application equipment should be thoroughly cleaned. The application time should be averaged every ten minutes and the amount of liquid should be strictly controlled
4.6 Use of other pesticides
When other pesticides must be applied to ensure the normal growth of the test crops, the amount of pesticides should be selected and the treatment and control plots should be treated uniformly. The pesticides used, time, dosage, etc. should be recorded in detail. 5 Final residue test
5.1 Application dosage
Set more than two application dosages. Under the premise that no complete failure occurs, the highest recommended dosage of the registration H shall be used as the low dosage of the residue test, and 1.5 to 2 times of the low dosage shall be used as the high dosage of the residue test. The unit of application amount is consistent with the unit of dosage on the pesticide label. For example, the application amount for agroforestry, small vegetables and other crops is expressed as "effective ingredient", and the application amount for fruit trees, tea and other crops is expressed as "effective ingredient". 5.2 Application frequency and time || tt || The maximum number of control times deduced at the time of registration and the number of times increased by 1 are the number of applications for residue test: for treatment agents such as seed treatment agents (seed dressing agents), herbicides or plant growth regulators, the number of applications for residue test may not be increased: - generally 5.3 Harvest interval
According to the actual situation of pest control for root crops, weeds, and clothing products, the appropriate harvest period and the estimated harvest interval for the test products to be picked during the spraying period are as follows: cucumber, tea, etc. The test harvest interval should be shorter, such as 2-3-5-1 or 7-1 days for other crops, such as watermelon, citrus, oranges, etc.The interval can be appropriately extended, usually 7d14(..12h). Each residue test is set with more than two harvest intervals, and the second year is a test: 6. Dynamic degradation test
6.1 Expression of degradation dynamics and half-life
The degradation of pesticides is expressed as the time required for the half-time of degradation of pesticide residues, that is, half-life. It can be expressed by graphical method: Plot the degradation curve with the residues of pesticide active ingredients or metabolites and degradation products as the ordinate and time as the abscissa. 3: 2 (linear regression) The half-life is calculated. The residual amount of pesticides in crops and the environment after application generally changes with time in a law of decreasing logarithm. It is calculated using the reaction dynamic equation formula: Gt-Gne K?
(—time (d into) pesticide line residue, unit gram, kilogram (k): one original deposition amount after application, unit gram kilogram (tr): K—dissipation coefficient;
T—time after application, unit day or hour (chengh) 6.2 Dissipation dynamic test type
single crop should be done on the edible part of the crop (plant or fruit), the dynamic "action" in the soil also needs to do the pesticide in the daily water meter dissipation station test: in order to avoid too much cattle length dilution as a knife, do sticky plants or fruits! Choose sticky plants when expressing Or when the fruit is about one square meter in size, start applying the pesticide: 6.3 Dosage for dynamic dissolution test
Use the high dose of the final residue test as the chain drug card for the dynamic dissolution test. When the residue is very low (low 10 times the minimum detection concentration), increase the application of pesticide according to the minimum detection concentration of the analytical method: When spraying plants cannot ensure uniform coverage of the soil and affects soil rolling sampling, spray the pesticide in a special area or another special area of equal size: herbicides and other soil treatment pesticides are carried out according to the application requirements. NY/T 788—2004
6.4 Sampling interval and frequency
The test was conducted by applying pesticides multiple times and taking samples multiple times in the same plot. Samples were taken at 0:00, 1d, 3d, 7d, 14d, 21d, 30d and 45d, respectively, within 2h of the basic temperature of the pesticide solution (i.e. the original sedimentation). For pesticides that degrade quickly, the sampling interval in the early stage should be calculated in hours. The sampling frequency should be no less than 6 times. The minimum residual amount in the last sample should be such that the degradation rate is more than 90%. 6.5 Dynamic degradation test of soil treatment agents and seed dressing agents For soil application of granular agents, seed dressing agents (coating agents), pre-emergence soil treatment agents, etc., samples can be taken at different intervals starting from the time of seedlings to study their degradation trend (the half-life can be ignored). period, or calculate the half-life based on the peak release event as the original deposition scene): 7. Collection, transportation and storage of samples for residue tests 7.1 Sampling methods
7.1.1 Random method: Determine the plants to be collected in the plot by pulling random numbers 7.1.2 Diagonal method: Collect samples at fixed points in the plot in an X-ray shape, 7.1.3 Method: A special case of the diagonal method, or sample at fixed points in the middle and four corners of the plot: 7.1.2 Selectively sample at the selected sampling points, and avoid sampling diseased, too small or immature samples: When collecting fruit tree samples, samples should be collected from all parts of the plant: top, bottom, inside, outside, sunny and shady sides), and more samples should be collected from parts with dense fruits. 7.1.5 Avoid sampling at the edge of the field or the side of the pond (leave a 0.5m edge). Collect all edible parts as required, and pay attention to as much as possible 7.1.6 First collect samples from the control area, and then collect samples from other plots in the order of small to large doses. Collect a representative sample from each plot. 7.2 Sampling volume and sampling location. 7.2.1 Determine the sampling location and sampling volume according to the crop classification, sampling location and recommended sampling volume. 7.2.2 Take 15cm2 soil samples from ten soil products as 1cm2/15cm2 layers. Set 5-10 sampling points in each plot. The sampling volume is not less than 1kg. For the soil decomposition dynamic test, take 1000ml of soil samples from multiple points. After mixing, take 1000ml-2000ml. 7.3 Sample disposal. 7.3.1 Avoid residual agricultural products on the surface of the sample during the collection, loading and preparation of the sample. 7.3.2 Avoid damage and deterioration of samples during sample collection and transportation to avoid affecting the residual amount. 7.3.3 Soil and other debris adhering to the sample can be brushed off with a soft brush or wiped off with a cloth, but avoid cross contamination. 7.4 Sample reduction
7.4.1 Reduce the sample into laboratory samples and 7.4.2 For smaller samples, such as wheat grains and small fruits, use the quartering method to further divide the sample into the actual experimental samples. 7.4.3 The sample cannot be blown, pass through a 1mm aperture sieve, and finally take about 250g-500g of sample and save it for testing. The test can be 1 yuan, +, and the upper residual amount can be corrected with dryness. For samples that cannot pass the soil sieve, remove plant branches and gravel and save them for testing. 7.4.4 For samples of medium-sized individuals, such as tangerine peel, the sample reduction may lead to loss of representativeness. Sufficient test samples can be collected from the fully mixed samples. 7.4.5 For samples of larger individuals, such as cabbage, watermelon and other vegetable and fruit samples, sufficiently representative samples should be collected. 7.5 Sample packaging and storage 7.5.1 Each sample collected should be labeled. The label should be rotatable and should be placed inside and outside the sample packaging. After the samples arrive at the laboratory, each sample should be assigned a number and accompanied by the sample analysis at each stage. The product information (sample name, sampling time, location and precautions, etc.) should be delivered to the laboratory within 24 hours. After the sample is received, the personnel shall check and record the sample information, check and record the sample status and whether it is consistent with the product information and the sample records are complete and accurate. If necessary, they shall be supplemented by checking with the test organizer.
7.5.2 The samples shall be packed in containers that do not contain analytical interfering substances and are not easily damaged. They shall be stored in a freezer or refrigerator as soon as possible. 7.5.3 Fresh samples arriving at the laboratory shall be stored at 1-5°C (maximum 3-5°C) and tested as soon as possible. If they need to be stored for a long time or are frozen samples, the samples must be stored at -20°C and tested after thawing. Some pesticides may degrade during storage and need to be verified by adding yield tests under the same conditions. For products that are tested separately for peel and pulp, they should be separated and packaged separately before freezing. Generally, samples shall not be frozen after pulping unless it is proven that this will not cause loss of pesticide residues. However, the samples can be extracted and the solvent removed before being stored at -20°C. Water samples shall be stored above freezing point to prevent freezing and cracking. When taking frozen samples for testing, the water samples shall not be separated from the samples and the pulp shall be reversed when necessary. The tested samples shall be stored for at least 1 year for re-testing.
8 Field test records
See Appendix 13. Field test record table for pesticide residue test 9 Residue analysis
9.1 Detection method
9.1.1 Selection of detection method
All established detection methods must be validated to prove that the selected method meets the analysis requirements and is feasible. The performance test of the method should be measured by the sensitivity, accuracy and precision of the method. Usually, sensitivity is expressed by the lowest detection concentration of the method; accuracy is expressed by the method addition recovery rate; precision is expressed by the relative standard deviation. 9.1.2 The minimum detection concentration (LO0) must be lower than or equal to the recommended MRI value. 9.1.3 Recovery rate
In principle, the addition concentration should be close to the pesticide content of the sample to be tested. However, the pesticide residue in the sample to be tested is unknown. Therefore, the maximum residue limit (MRI) of the sample and the minimum detection concentration of the method are generally used as the required concentrations, that is, at least 2 addition concentrations must be selected for the addition recovery test: If there is no recommended MRI, the minimum detection concentration and a concentration 10 times the minimum detection concentration are used as the addition recovery rate: The required recovery rates for different addition concentrations are shown in Table 1.

9.1.5 Preparation of standard curve
.-Generally, the external standard method is used for quantification. The standard curve is prepared with the absolute amount of the test pesticide (1g) as the horizontal axis and the response value (such as peak height or peak area) as the vertical axis. The linear response range is determined, and the regression equation and correlation coefficient are calculated. The number of test points for drawing the standard curve shall be no less than 5. 9.2 Confirmation of pesticide detection (confirmatinn test) 9.2.1 Conditions of confirmation test
In the case of qualitative uncertainty in the test results, a confirmation experiment is still required before reporting the test results to avoid making wrong conclusions: Usually, the test pesticide is confirmed by changing the extraction, purification, separation and detection techniques according to the physicochemical properties of the pesticide and the characteristics of the medium. Usually one of the following methods can be selected for confirmation: 9.2.2 Chromatographic column change
That is, use another chromatographic column with different polarity and test conditions for detection. At this time, the relative retention index of the analyte often changes significantly and confirmation can be achieved.
9.2.3 Detector changes
Change the detector, especially the selective detection test 9.2.4 Gas-mass spectrometry or liquid-mass spectrometry technology
First, the retention time, peak shape and response value of the pesticide to be tested in the total ion current chromatogram (T) should be consistent with the standard. Since the H ionization method cannot provide enough molecular structure information, the electron beam method (EI) is generally used: the composition should be referenced to the mass spectrum of the standard substance under the same conditions or the mass spectrum established under similar conditions. When the full scan mode (Scan) is not flexible enough, you need to select the separation mode (SIM). At least 2 special ions with a mass unit of more than 200 or 3 special ions with a mass unit of more than 100 should be selected. The ion ratio of each ion should be consistent with the standard spectrum at a rate of 70% to 130%. In qualitative testing, special attention should be paid to the isotope ion, which can provide reliable qualitative information. Before comparing the spectra, the instrument and sample should be carefully selected to ensure that the sample is consistent with the standard spectrum. 9.2.5 Change of detection method
In certain cases, changing the detection system is also a good choice, such as changing gas chromatography to high-performance liquid chromatography or changing thin-layer chromatography to spectroscopy.
9.3 Calculation and presentation of results
The results are calculated and data statistics are performed based on the detection method adopted. The most commonly used calculation methods for chromatography are external standard method and internal standard method: The residue should be the sum of the pesticide itself and its toxic metabolites and degradation products, which can be expressed as: When the measured value is lower than the lowest measured concentration, "<set lower detection concentration value" should be written. The actual test results should be recorded truthfully, and the repeated test values and average values of each sample should be listed separately, and the recovery rate cannot be corrected.
The results are expressed in two significant figures (such as 0.11.1.1, 11 and 1.1×10, etc.). When the residual concentration is lower than 0.01 mg/kg, the relative standard deviation is even greater. At this time, the results can be expressed in 10 significant figures: For statistical purposes, one significant figure can be added respectively. The recovery rate can be expressed in integer percentages: For soil products, it is calculated based on fresh weight for weeds, and for plant samples. 10 Writing of test report
