WHO revises air pollution guidelines; Indian standards alarming

Air pollution levels across India stay beyond WHO guidelines.

Among the different aspects important for healthy living, clean air is the most significant. The World Health Organisation (WHO) had, in 2005, set basic guidelines which said that air pollution beyond particle matter 2.5 concentration of 25 micrograms per cubic meter per 24 hours was considered unhealthy. However, after extensive research, WHO has concluded that pollution beyond particle matter 1.5 concentration of 25 micrograms per cubic meter per 24 hours is unhealthy. WHO has revised figures of six most common pollutants, namely particulate matter 2.5, 10, Ozone, Sulphur Dioxide, and Carbon Monoxide.

Air pollution standards in India lenient

The National Air quality standards are among the most lenient in the world and are far below even 2005 WHO standards. Air pollution issues hardly find a place in the media or debates. Compare the Indian figures to WHO guidelines - while Indian air pollution standards find PM2.5 concentration over a period of 24 hours of 60 micrograms per cubic meters normal, WHO recommends 25 micrograms, as per the 2005 guidelines.

The fact is that even Indian standards are not being followed. The Government of India is planning to reduce air pollution in major cities across India by 20 to 30 percent on a 2017 baseline by 2024.

Air pollution has a debilitating effect on the health of the population. Coupled with unhealthy habits like tobacco use and smoking, it aggravates the situation. There has been a 10-fold increase in respiratory ailments in India. A major proportion of the rural population still uses firewood and coal for cooking.

Air quality in almost entire India beyond WHO norms

It has been earlier reported that, by WHO’s new standards, almost the entire nation is polluted. Nature has the ability to bounce back if mankind ceased its activities for some time. This was evident during the lockdown imposed during the Covid pandemic.

The quality of rivers improved considerably and the Himalayas were visible from distant places, something which was not possible earlier.  There are talks that such periods of inactivity will be very helpful and must be practiced on a regular basis.

Lathi Charge: A legalised method of police brutality

"Every blow on our bodies this afternoon is like a nail driven into the coffin of British imperialism." These were the precise words of Sher-e-Punjab Lala Lajpat Rai when he got brutally " lathi-charged " by the law enforcers of Colonial India while he was protesting against the Simon Commission in October 1928.  Punjab Kesari Lajpat Rai eventually succumbed to his injuries, and his death gave off the spark for vengeance in the heart of numerous Indian revolutionaries. In December 1928, Shahid-e-Azam Bhagat Singh and his compatriot Shivam Rajguru assassinated the Lahore Assistant Superintendent of Police (ASP) John Saunders to avenge the murder of their mentor. "Lathi-Charge" has remained one of the most brutal and sensitive issues for Indians since the bygone days of the Indian National Movement. Thus, even after 75 years of liberation, India and her children continue to writhe under pain brought on by police brutality and paranoia. Both the Indian Penal...

" India is an over populous country. " This statement is hardly news to anyone, but very few of us know that the average age of an Indian is just 29 years old. Hence, India is a fairly young country with a strong demographic dividend. However, the ambitions and dreams of millions of Indians lie stranded despite their ability and competence. Each new year brings fresh new hopes for millions of aspirants. These young people have expressed their strong will by deciding to dedicate the prime of their youth to preparing for numerous government examinations. In a country where social class divisions continue to be a notable phenomenon in determining one's future, Government jobs and recruitments offer the only genuine means for attaining an egalitarian society. Today, even this little scope for upliftment gets marred under the evils of Paper leaks and Recruitment scams. The problem of the youth, in essence, is the problem of the nation, and it is high time we illustrated the gr...
