Some standard content:
National Standard of the People's Republic of China Maximum allowable concentration of air pollutants in atmosphere for protection of crops Maximumallowableconcentrationotpollutants in atmosphere for protection of cropsUDC614.79 GB913788 According to In accordance with the relevant provisions of the "Environmental Protection Law of the People's Republic of China (Trial) and the Atmospheric Pollution Prevention and Control Law of the People's Republic of China", in order to maintain a virtuous cycle of the agricultural ecosystem, protect the normal growth of crops and the high quality and high yield of agricultural and livestock products, standards are specially formulated to protect the products protected by this standard. The main targets are crops with important economic value, cane vegetables, fruit trees, mulberry tea and harvested grass. This standard is a supplement to GB3095-82 Atmospheric Environmental Quality Standard. 1 According to the tolerance of various crops, vegetables, fruit trees, soft tea and pasture to two chemicals and oxidants, crops are divided into three different types: tender, medium sensitive and resistant, and the concentration limits are set respectively. The classification of crop number sensitivity is based on the comprehensive consideration of various atmospheric pollutants on crop productivity, economic traits and leaf damage. The degree limits of various air pollutants are listed in Table 1. The National Environmental Protection Agency approved the implementation on 1988-04-30 and 1988-10-01 Pollutants Rat |tt||Vegetables Chemical Crop synergy degree sensitive crops moderately susceptible crops resistant crops||tt| Sensitive cropswww.bzxz.net Moderately sensitive crops Resistant crops GB9137-88 Table 1 Micro-limit values ??of air pollutants for protected crops Growing season average||tt ||Liquidity! 0.05 0.08 0.12 1.0 2.0 4.5 Self-average roll 0.15 0.25 0. 30 5.0 10.0 15.0 any time 0.50||tt| | 0.70 | , potato apple, pear, grape pig, clover, grass, ryegrass water frost, corn oats, high fruit, cotton, tobacco tomato , Hanako, Chaolibu Peach, apricot, plum, citrus, cherry Broad beans, rape, Xiangri Fang Cale, taro 0. ao| | tt | Moss paste, ryegrass, duckweed Barley, rice, corn, sorghum and soybean Chinese cabbage, mustard, cauliflower Sweetener Three-flower grass||tt ||Xiang Gan Tomb, Cotton, Tea Fennel, Fandan, Eggplant, Chili Chao, Potato Note: 1) The "average growing season density" is the daily average purchase density value in any growing season and must not exceed limit value. The 22-day average concentration is the limit that the average pus concentration on any day cannot exceed, and the 3 "once every ten days" is the concentration limit that cannot be exceeded in any sampling measurement. 4) Trioxide concentration unit is m/m . 5) Fluoride loading unit is ug/dmd) 2 The concentration limits of air pollutants for various crops with different sensitivity are guaranteed under long-term and short-term exposure. The air quality requirements for the normal growth of various crops without causing acute or chronic damage are 3 concentration limits for chloride-sensitive crops, in addition to protecting the normal growth of crops, vegetables, fruit trees, mulberry leaves and pasture without causing acute or chronic damage. , and also ensures that the average monthly oxygen content of Chengye and Muzhang within one year does not exceed the concentration adjustment values ??of 30 mg/kg and 40 mg/kg, respectively, to protect animals affected by hormonal and sexual diseases from harm to the 4 standard. Implementation and management: This standard is supervised and implemented by environmental protection departments at all levels together with clothing industry environmental protection departments at all levels. 5 Monitoring methods 5.1 Working procedures for analysis methods such as point layout, sampling, analysis, and data processing in atmospheric monitoring. , temporarily in accordance with the relevant provisions of the Environmental Monitoring Analysis Method 3 (1983) promulgated by the Environmental Protection Bureau of the Ministry of Urban and Rural Development and Environmental Protection. The monitoring methods of various pollutants in the 5.2 standard are shown in Table 2.
