Description

The method for monitoring particulate matter quality in urban green space area plant leaf blade retention dew
Technical field
The present invention relates to particle monitoring technical fields, and in particular to one kind can be monitored effectively and with calculating urban green space area Table plant leaf blade is to the method for dew trapped particles amount of substance.
Background technology
Dew condensation is the meteorologic phenomena generally occurred, using aerosol tiny in air as condensation in forming process Core plays an important role to air purification, and the condensation of dew is the natural process of near surface particulate matter sedimentation removal.Urban ecology system Tong Zhong greenery patchess area is the important place of dew condensation, and annual dew amount is equivalent to the rank of heavy rain up to 60mm.In dew Particle concentration is significantly higher than other wet deposition forms such as rainwater, and the particle concentration dissolved in dew is 271.36mg/L, is sunk It is considerable that particle object amount drops.But dew condenses at night, is evaporated after sunrise, part be settled down to the particulate matter of blade with Wind turns again near surface, such as part PM2.5Earth's surface is returned to, the air pollution of near surface can be increased, seriously affects mankind's activity model The air quality enclosed threatens health.Therefore urban green space area vegetation cuts particulate matter in dew after accurate measurement sunrise Allowance is extremely important.
It is more mature in terms of monitoring and calculating plant and cut dust quantity both at home and abroad at present, but related monitoring calculation plant is to dew The technique study of particulate matter interception after middle condensation re-evaporation is more rare.
At present, what the retention method of particulate matter was applied in urban plant is blade minusing, and this method has following defect：
1st, prior art is to calculate plant leaf blade trapped particles object dry deposition amount, i.e., is dropped with particulate matter self gravitation Drop down onto the part of blade.Part of the night as the nuclei of condensation with condensation vapor to blade can not be weighed.There is presently no method prisons Survey or calculate the part that dew condensation particulate matter is retained by blade.
2nd, the minusing of existing method sampling calculates blade by the weight change of the blade of a period of time and cuts dirt Amount.The method used is " thoroughly elution wiping to be carried out to blade surface using the cotton ball soaked in alcohol that distilled water moistened, removes blade After the stagnant dust of institute ", but it is halfway to only rely on wiping, such as some fine particles on the villus of blade or in fold, It can not ensure thorough wiped clean.Therefore the result of calculation of existing method is inaccurate.
3rd, existing method can only calculate total particulate matter quality (TSP), and particulate matter can be divided into inhalable particles according to grain size Object (PM10) and lung particulate matter (PM2.5) and overall suspended pellet (TSP) etc., but cannot weigh and haze weather and human body are good for The very important monitoring index PM of health2.5And PM10Etc. indexs.
Therefore it provides one kind can system comprehensively to urban green space area plant leaf blade in dew condensation-evaporation periods The method of different diameter airborne particle interception is imperative.
The content of the invention
To solve the above problems, the present invention provides particulate matters in a kind of monitoring urban green space area plant leaf blade retention dew The method of quality.
To achieve the above object, the technical solution taken of the present invention is：
A kind of method for monitoring particulate matter quality in urban green space area plant leaf blade retention dew, which is characterized in that including Following steps：
Step 1：Complete stool blade total amount counts：
Using standard branch top and bottom process, to carrying out branch grade layering for examination plant, divide to the standard sprig of easy counter-blade Until, random sampling statistics is carried out to each layer branch quantity, is chosen respectively from the direction of east, south, west, north 4 on final stage branch The standard sprig of 30cm long counts blade quantity, calculates complete stool blade total amount N (piece)；
Step 2：It can be filled in the random multipoint acquisition in upper, middle and lower portion of the direction of the tree crown periphery four corners of the world 4 and middle part branch Tap receives n pieces of the plant leaf blade of dust, and blade quantity is 30~50 pieces, and leaflet is 60~80 pieces.After leaf sample is sealed, avoid shaking It is dynamic to take back laboratory immediately；
Step 3：Each group blade surface be cleaned by ultrasonic 30 minutes using deionized water, removes the stagnant dust of blade institute, Blade is made to reach initial nil product dust quantity；
After the completion of cleaning, various types of blade is divided into two groups, is uniformly fixed on respectively on polystyrene foam plate, villus Up；
Step 4：When dew condensation starts, the blade obtained by step 3 is placed in monitoring point, keeps polystyrene board and earth's surface It is parallel, and in plant canopy height；
Switch to the timing node of evaporation in dew condensation, wherein a cystosepiment sealing will take back laboratory, and use deionization Water concussion cleaning blade surface, record amount of deionized water Vc(L), particulate matter TSP in washing water, PM are tested and2.5, PM10Concentration (Cjc, mg/L)；
Step 5：After dew evaporating completely, laboratory is taken back into the sealing of remaining cystosepiment, is shaken and cleaned with deionized water Blade surface, record amount of deionized water Vc(L), particulate matter TSP in washing water, PM are tested and2.5, PM10Concentration (Cjc, mg/L)；
Step 6：The calculating of delay different-grain diameter particle quality after individual plants sedimentation and evaporation is carried out by the following formula：
In formula, j for particulate matter type (such as：PM2.5/PM10/TSP)；FjFor what is settled during individual plants dew condensation Particulate matter quality (mg/plant)；CjcParticulate matter quality in cleaning blade deionized water is shaken when turning evaporation node for dew condensation Concentration (mg/L)；VcDeionized water volume (L) used in cleaning is shaken when turning evaporation node for dew condensation；2 be transformation ratio；Pj Deposited particulate matter quality (mg/plant) after being evaporated for individual plants dew；CjeCleaning blade deionized water after being evaporated for dew Middle particulate matter quality concentration (mg/L)；VeDeionized water volume (L) used in cleaning after being evaporated for dew；N is acquisition individual plants The number of blade (piece)；N is individual plants blade amt (piece).
The present invention can monitor and calculate urban ecological system every night green floristics from different places to night dew condensation, By the particulate matter of the different-grain diameter of blade retention after evaporation, operating procedure simple computation method is clear and definite, easy to spread；And it can keep away Exempt from original technology by halfway drawback is wiped by hand, accuracy rate is higher.
