iil 4.1.2 Air Monitoring as Dust particle (Representing Data in data table & graph)

The air quality of the selected locations of Mirsharai has been monitored by using a particle counter. Air has been monitored in terms of dust particle TSP (total suspended particulate) and particulate matter (PM). The Particulate Matter (PM) of different sizes such as PM 0.5, PM 2.5, PM 5, PM 10 & TSP has been assessed by particle counter. The particle counter utilizes the laser technology for single particle detection. The scattering of light from the particles in the sampling air steam is converted into electrical pulses, which is then measured and calculated as a particle size.Monitoring has been conducted for L hour interval. ln every hour, 3 data for every parameter has been taken. Each location has monitored separately, 8 hour in Day time (8.00 am to 1.00 pm & 2.OO pm to 5.00 pm) and 3 hour in night time (8.00pm to 11.00pm). The unit used for dust particle is pg/m3 (or PPM). The Air monitoring results of 03 locations are given below in data table and as graphical presentation.

All the percentage values by which the data are lower than standard limit have been mentioned in the above sections separately for each location.

-'lll Water samples have been collected from 9 nos of locations. pH, Temperature, Conductivity, Total Dissolved (TDS), solids Arsenic (As), lron (Fe), Free chlorine, Total chlorine, Total Coliform, Dissolved Oxygen (Do), Biochemical oxygen Demand (BODS), Chemical oxygen demand (coD), Calcium (Ca) and Potassium (K) have been tested for each sample. Water samples have been collected on June 12, 2019 by Qtex Assessor.

Sampling Procedure:

Sampling of surface water has been conducted by following grab sampling method. As per etex Technical Procedure "TP-l-0-Sampling Plan & Procedure" water sample has been collected by Qtex assessor proper who has training and relevant knowledge on sampling technique. Sample is collected in sterilized bottle. The assessor used hand gloves during collecting sample for avoiding any contamination. ln case of handling & storing the sample Qtex technical procedure "Tp L1_procedure for Sample Approval & Rejection, Reception, Handling/Transportation, Storage & Disposal,, has been followed. As per TP 11 the sample containers are carefully packed to avoid any breakage or cross contamination. For transporting the sample from project area to etex laboratory, ice box has been used to carry the sample bottle. All samples are properly stored from the time they arrive at the laboratory until disposil. Samples has been stored in refrigerator at 4"C prior to analysis which preserve the majority physical, of chemical and biological characteristics in the short term (< 24 hours). The sample process testing has been started by Qtex analyst within 24 hours of receiving the sample.

After the establishment of economic zone, vehicular movement in the concerning area will drastically increase. lf the people at these locations stay continuously with the high level of noise, it may cause hearing damage in the long run. A step to create natural buffer (e.g. tree plantation) to control noise can be truly helpful. The concerning authority can think of planting trees to create this buffer. The below measures can be considered to controlthe noise pollution.

{ Taking noise control measures in the noise generating machineries of the industries which would be established in future. ./ Tree plantation to create natural buffer. { Controlling vehicles with hydraulic horns. { Creating awareness among the drivers and general people.

ln most of t]re cases, high noise is generated due to vehicular movement. Studies says that a 100ft wide planted buffer will reduce noise by 5db to 8db. Using a barrier in the buffer such as a landform can significantly increase buffer effectiveness (10db to 15dB reduction per 100 ft wide buffer with 12 ft high landform). Buffer should be created to the closest possible location to the noise creating source. Evergreen species will offer year-around noise control. This can be pictured as bellows-

After the establishment of economic zone many industries will be introduced here which will definitely take necessary effect on the air quality of this area. The industries to be established should themselves steps to steps to minimize the air pollution. Besides this, the concerning authority can take some the beauty create vegetation in this area which will help to keep the air fresh and will also enhance 75 percent' of this area. A 65 to 600 ft wide buffer may reduce particulate pollution by around 40 to particulate pollution and As the industries will add air pollution, tree buffer will help to reduce both gaseous pollution. The buffering should be done around and close to the pollution source.

Plant selection Criteria for Air Pollutant Removal can be as bellows: to ! Evergreen trees can remove more pollutants however many conifer species are sensitive common Pollutants' Select plants with dense branching and twig structure' leaves' Leaves with hairy, resinous, and coarse surfaces capture more particles than smooth Smaller leaves are generally more efficient collectors than larger leaves' Herbaceous species may adsorb more gaseous pollutants' Uie multiple species to minimize risks with low diversity'

Use long-lived species that require minimal maintenance' Select species with pest and disease resistance. Select species suitable for the site
