Air quality: Hyderabad in pollution!

• ABC MEDIUM
• ABC LARGE
• ABC EXTRA LARGE

In falling, Hyderabad is competing with the national capital, Delhi. On the first day of the new year, the AQI reached up to 300 in many areas. This is a calculation of indexes registered by third party, Google apps and devices. But it is noteworthy that in the indices set up by CPCB, the new year has recorded a maximum of 170. Some retired professors say that there is no accuracy in the measurements prescribed by CPCB. The Pollution Control Board has installed ACI devices in 14 areas of the city. Through these, the maximum and minimum indices are revealed. If the ACI exceeds 100, then there is a threat. In December, the maximum ACI in Hyderabad was only 132 according to PCB calculations. AQI recorded in third-party apps is up to 270. Scientists say that there should not be such a difference. The cost of the machines that measure air quality as per European standards is around Rs 30 lakh each. The researchers say that the devices using PCB are not at that level. 

Three Types of Air Pollution

Air pollution is considered in three types which are bio, physical and chemical reactive. Moisture in the air, bacteria, and odors from solid waste management fall into the first category. Fine dust particles fall into the second category. Carbon dioxide, nitrogen oxide, sulphur, methanol, benzene etc. which cause chemical effect are taken in chemical reactive. If these standards are exceeded, people will get lung diseases and cancer. 

If there are about 80 lakh vehicles in Hyderabad.. An average of 50 lakhs hit the road every day. The smoke emitted from these is affecting the air quality. Apart from these, pungent odors emanating from buildings, garbage, sewage and industries are deteriorating the air quality. 

AQI is calculated based on various elements in the air. PCB calculates according to national level air quality standards. Third party apps are calculated according to USEPA standards. That makes a difference. Apps show only the maximum without considering the minimum. PCB takes the average. If we look at the USEPA standards and not our national standards, we have a higher ACI. 

No trust in PCB devices. The Google app is somewhat true. Air quality in Hyderabad is deteriorating badly. I am doing research on this. While working on developing an air quality measuring device. Will reveal after completion. I am of the opinion that ACI equipment should be as per international standards.

At 8.30 am on Saturday, the air quality index in KPHB Colony, Hyderabad indicated 302. It is equivalent to AQI (Air Quality Index) in Delhi. But, there is no CPCB (Central Pollution Control Board) air quality index in this area. According to CPCB's calculations on Saturday, the ACI in Hyderabad's Bollaram industrial area was the highest at 142 and the lowest at Ramachandrapuram was 73.

The air quality is dangerous only if it exceeds 100. If it reaches 300.. there is a possibility of contracting various diseases for those who breathe that air. Scientists warn that smoking it is equivalent to smoking 30-35 cigarettes a day. CPCB is recording the air quality. There are criticisms that accurate calculations are not coming anywhere. The reason for this is that there is a huge difference between the indices announced by the third party, Google App and CPCB.
