Particulate size studies : We can provide the particulate size analysis by using the technique of Electron Microscopy. The Electron Micrograph will show the size of particulate at angstrom/micron level. The results can be given in photographic form. Average size distribution of particles can also be studied. The results will be given in graphical form. |
| |
| II. Respirable particulate sampling, by using respirable particulate sampler, for estimation of total SPM, respirable SPM (< 10 micron size), free silica, lead etc. |
| |
| i) |
Total SPM ( greater than 10 microns ) |
| ii) |
Respirable particulate ( less than 10 microns ) |
| iii) |
Free silica, lead in respirable particulate fraction. |
|
| |
| III. Micrometeorological data like wind speed, direction, relative humidity, temperature (maximum and minimum) etc. Dust fall measurements etc. Installation of site metrological lab. |
| |
| IV. After recording site-specific met data, stack emission predicated modeling can also be taken up using ISCST3, 5, (to determine short and long term impacts) standard software accepted and followed by MoEF New Delhi. Modeling using ISCST / CPCB approved software for determining dispersion of air pollutants around the periphery of the plant / Mine. |
