B.G. Siddharth, Director of the planetarium, on Sunday said the show would highlight the recent scientific findings that dark energy permeates all space leading to expansion of the universe unlike the earlier belief that it consisted of dark matter, and that it would collapse.
- Mobile air quality monitoring station also suggests necessary action
- Hazardous waste laboratory helps generate data for policy measures
The Andhra Pradesh Pollution Control Board (APPCB) has acquired two new facilities, a mobile online ambient air quality monitoring station and hazardous waste laboratory, which were inaugurated by the Chief Secretary, Mohan Kanda here on Saturday. The mobile laboratory monitors the air quality at a site and assesses air pollution caused by sources including industries and exhaust gas from automobiles. It will help determine whether the air quality at a particular site meets the environmental standardsand also in establishing grounds for necessary measures.
The laboratory has gas analysers and meteorological sensors to assess air quality and will help generate data needed for policy measures for corrective action on environment front, PCB officials observed.
The hazardous waste laboratory has been equipped with an apparatus to measure the flash point of volatile liquids based on which the ignitability could be assessed and bomb calorimeter to measure the calorific value of the organic substances. It also has TCLP extractor, TOC analyser and a pH meter.
