Crushing produces mainly coarse (TSP and PM 10) dust particles which settle near the dust source. The mass concentration of coarse particles varied from few tens of μg/m 3 to over 6 × 10 3 μg/m 3 downwind from the crusher. The mass concentration of fine particles (PM 2.5 and PM 1) ranged between ten μg/m 3 and few hundreds of μg/m 3 ...

Stone crusher plants can generate significant amounts of dust, which can lead to air pollution. This can have negative impacts on both the environment and human health. To mitigate this impact, stone crusher plants should be equipped with effective dust suppression systems, such as water sprays or enclosed systems.

The aim of this study was to assess the effects of stone crushing dust pollution on three commonly cultivated fruit plant species (Vitis vinifera L., Morus alba L., and Prunus armeniaca L.) and on the health of workers working at crushing plants. The trial was carried out on fruit plant species grown close to the stone crushing units located …

The joint committee was also asked to "carry out ambient air quality monitoring in the nearby areas where the stone crusher units are situated and also to identify possible sources of air pollution in those localities." Many stone-crusher units did not adhere to the state guidelines, the study report found. MPCB had to issue a blanket …

Other things remaining the same, air pollution, particularly dust pollution, causes a significant fall in crop yields, and in turn, agriculture income reduces. Hence a modest attempt has been made here to study the influence of dust pollution by stone crushing units in the surrounding areas of Virudhunagar District.
