CPCB stands for
(a)Chemical Pollution Control Board
(b)Classification of Pollutant Control Board
(c)Central Pollution Control Board
(d)None of the above

Hint: To regulate all forms of emissions, the CPCB handles environmental information statistics. Evaluation of pollution (survey and tracking) is a CPCB feature. This refers to the Ministry of Environment and Forests.

Complete answer:
CPCB stands for Central Pollution Control Board.
-Central Pollution Control Board (CPCB) acts as the Ministry of the Environment and Forests. The CPCB also promotes the cleanliness of streams and wells through the prevention, control and reduction of water pollution in various areas of the state. It was created in 1974 under the Water (Prevention and Control of pollution Act, 1974.

Functions at the level of national, state and union territories.
-CPCB operates national environmental air quality control systems, known as the National Air Quality Monitoring Program (NAMP).
-The CPCB is responsible for regulating and monitoring the output and generation of noise sources with the goal of preserving the quality levels of ambient air.

Additional Information: Via the following nine main project \ budget heads, the CPCB executes its various functions.
-Assessment of Emissions
-R&D and supervision of laboratories.
-Development of industry-specific emissions and effluent requirements and guidelines
-Training Education
-Database management and library information
-Technology to manage emissions
-Regulation Emissions Management
-Mass consciousness and publications
-The treatment of hazard waste
So, the correct answer is, ‘Central Pollution Control Board’.

Note: Particle sizes of 2.5 micrometres or less in diameter are responsible for causing a lot of damage to human health, according to the Central Pollution Control Board. Inhaled and penetrating deep into the lungs, these small particles cause respiratory diseases, pain, inflammation, lung injury, and premature deaths.
