Read Article on Dust Emission Due to Stone Crushers in Pune

Dust is smallest matter of crushed aggregate which present in the open atmosphere. Due to the physical and chemical properties of dust particles, they cause adverse impacts upon the environment, atmosphere, human being and overall surrounding Earth’s system.

Dust is being emitted from different crushing industries, which becomes a serious problem for living and non living things. Particles flow in open atmosphere for longer distance due to wind which blows from crusher’s area. Weather condition, wind speed, wind directions and characteristic of dust particles are responsible factors for distribution of dust particles. The precautions taken during the processing of aggregates can help to reduce the emission of dust particles in the atmosphere. The study represents the dust emitting sources, dust pollution and its effects on different plants, sources of surface water and ground water in Katraj of South Pune, Maharashtra. The region is in developing phase which produces large amount of aggregates and hence generate huge quantity of dust matter.

Tuberculosis is a major threat to the health of millions of populations. Mycobacterium tuberculosis and various microorganisms like bacteria, fungi remain in a self-produced polymeric matrix, adherent to an inert or living surface. This microenvironment community of bacteria is known as biofilm. These biofilms cause various infections and are of at most importance when concerned about public health. One of the challenges faced during antibacterial drug development is to create compounds to counter-attack the biofilm infections. In this respect natural products having powerful antimicrobial effects remain important participants. The objective of this study aimed to investigate the anti-mycobacterial activity of the phytochemicals. Phytochemicals are chemical compounds formed during the plants’ normal metabolic processes. These chemicals are often referred to as “Secondary metabolites” of which there are several classes including alkaloids, flavonoids, coumarins, glycosides, polysaccharides, phenols, tannins, terpenes and terpenoids.
