Favorable conditions for improvement for air purification

1.                  Plant type - Indigenous including seasonal plants

2.        Capacity of plant to grow in pollutant area- in any         conditions and able to adapt themselves.

    Nearby open gutars and around polluted water bodies.

3.       Soil conditions provided - Porous, water-resistant, nutrient manipulation means we can add and make them adapt in some possible extent.

4.              Humidity and sunlight Intensity- Works 300 nm to 410nm and form 600 to 700 nm ..of red width including infrared section .. there are 7 plants on which this has experimented.

5.             Amount of plants- The number of plants kept in the area is quite important, at least 10 plants of mixed type should be kept in every 10 feet distance…

6.             Arrangements of leaves - compounds leaves and small size medium leaves with hand the arrangement is more efficient in air purification due to their collective surface the area is large.. and allow proper air the passage which maintains steady air current flow.

7.         Canopy size - canopy size should be large and 2/3  times more large than total branches area cover.. and trees should be in gap arrangement with loose canopy.

8.             Amount of pollutant- The amount of pollutant in the area is accelerated the purification process, searching on it more, as per reports, plants in local garden purifies more air than in coal factory garden…the more we feed the more they filter, but the best capacity is around 200 lb of air ..20 plants…if exceeds that limit..it will be poison to plants to some extent.

9.             Location- It refers to amounts of plants in an area at a definite distance around 100 Umbrella plants in just 1 km distance are minimum requirement…for cities like Raipur(3rd most polluted city in India .,2015) having air Pollution index at 540 mg/ m3 of air.. just before lockdown during November 2019, China has crossed the 784 mg/m3 mark on Feb 2019 recently.

10.        Altitude- Increase in Height decreases the purification levels as transpiration and wind currents blow away the pollutants ..preventing their absorption quality.

Best purification results are given up by average height plants when their the population is small and except for Nuclear sites and factories sites.. as pollutants intensity is maintained and heightened plants absorb more.

11.         Types of plant Studied- As per Reports I have gone through .. 89 plants are studied by NASA 1989 and 35 were selected…for purification experiments but only 14 were called best in any less updating conditions…Rest in India roadside plants like  mango, peepal, babul, garden plants like daisy are a quite good purifier but have some extreme allergic capacities due to incest, pollen content.

 

Rest plants are Indoor air control plants but have to be planted in large quantities for average air maintenance of 20 *20 room…which should be around more than 30 plants in numbers …for creating proper micro climate
