If you think mornings are the best time for outdoor exercise, you’re wrong.

Mornings experience the worst air pollution in four Indian cities, according to an analysis of particulate matter (PM) 2.5 data from IndiaSpend’s #Breathe air-quality sensors in Bengaluru, Chennai, Delhi and Mumbai between March 15 to April 15 2016.

Delhi: Best air quality —4 pm

Mornings were the worst time, with PM 2.5 levels reaching as high as 108.16 µg/m3 at 7 am. Air quality gradually improved as the day wore on, registering the cleanest air at 4 pm. (22.84 µg/m3). Pollution levels then picked up through the night.

Delhi topped the list of the world’s most-polluted cities, according to the World Health Organisation (WHO).

Bengaluru: Best air quality–midnight

The worst air was at 7 am, as PM 2.5 concentrations peaked at 61.54 micrograms per cubic metre of air (µg/m3). The air quality improved as the day wore on, worsening by evening at about 5 pm, reaching a late-evening high at 7 pm (57.60 µg/m3). The best air quality was registered around midnight, when PM 2.5 levels fell as low to 40.12 µg/m3.

Chennai: Best air quality—3 pm

The worst air was at 7 am, with PM 2.5 levels (61.54 µg/m3) reached their peak. Levels began to peak over the night and slide during the day, after 7 am. The best air quality was recorded in the afternoon, at 3 pm, with PM 2.5 levels reaching as low as 20.76 µg/m3.

 

Mumbai: Best air quality—5 pm

The worst hour for a Mumbaikar is 8 am, with PM 2.5 levels reaching 48.61 µg/m3; the air started to worsen after 5 am. The best air quality was registered at 5 pm, when PM 2.5 levels were 22.38 µg/m3.

Outdoor air pollution causes 670,000 deaths annually in India, according to a 2014 research paper from the Indian Institute of Management-Ahmedabad.

Air pollution has become a global concern with rising air pollution levels, as outdoor air pollution in cities and rural areas across the world estimated to cause 3.7 million premature deaths in 2012, according to the WHO.

Particulate matter is the term for particles found in the air, including dust, dirt, soot, smoke, and liquid droplets. These are classified according to their diameter. Particles less than 2.5 µm (micrometres) are called PM 2.5. They are approximately 1/30th the average width of a human hair. Particles between 2.5 to 10 µm in diameter are called PM 10.

PM 10 and PM 2.5 include inhalable particles that are small enough to penetrate the thoracic region of the respiratory system. The health effects of inhalable PM are well documented, caused by exposure over both the short-term (hours, days) and long-term (months, years). They include: Respiratory and cardiovascular morbidity such as aggravation of asthma, respiratory symptoms, and an increase in hospital admissions; and mortality from cardiovascular and respiratory diseases and from lung cancer.

There is good evidence of the effects of short-term exposure to PM 10 on respiratory health, but for mortality, and especially as a consequence of long-term exposure, PM 2.5 is a stronger risk factor than the coarse part of PM 10.

There is a close relationship between exposure to high concentrations of small particulates (PM 10 and PM 2.5) and increased mortality and morbidity from cardiovascular/respiratory diseases and cancer, both daily and over time, according to the WHO.

#MeToo: Star India internal panel writes to anonymous accuser to come forward

The Internal Complaints Committee of Star India on Sexual Harassment (Star ICC) has written to the anonymous accuser — who had alleged “sexual exploitation” of women employees — asking her to reach out to the committee or its external member on allegations made by her in tweets.

In a Twitter post on Friday, Star ICC, formed under the Sexual Harassment of Women at Workplace (Prevention, Prohibition and Redressal) Act, 2013 said it had reached out to the accuser through two emails on the ID provided by her through her tweets. The committee’s external member is Veena Gowda, a Mumbai-based woman rights lawyer.

The accuser, who tweeted through handle @ApurvaS17 — saying she would remain anonymous — had made sexual harassment allegations against the company’s officials in an open letter.

Star believes that the allegations made in the tweet without the complainant coming forward and giving any further detail, is a malicious attempt.

Asked to comment on the allegations, a Star India spokesperson said in a statement that despite no response by the anonymous accuser to the messages sent, the Star ICC had “suo moto conducted a preliminary inquiry and found no basis or factual accuracy” in respect of the allegations.

“We strongly urge any genuine complainant to approach the Star ICC. At Star, we stand with women in drawing the line on any behaviour that violates human dignity or the ability for women to pursue their dreams with respect and freedom. We have a zero-tolerance policy towards sexual harassment,” read the statement in response to an email query by IANS.

It also said that the anonymous tweet shared on October 13 raised an allegation that “runs completely counter to everything we believe in and the norms and values that we deeply embrace.”

The statement further said: “Star believes that the allegations made in the tweet without the complainant coming forward and giving any further detail, is a malicious attempt to malign and defame the reputation of the company and the CEO.” It said that Star reserves its right to initiate appropriate legal proceedings in this regard.

The Star ICC had “suo moto conducted a preliminary inquiry and found no basis or factual accuracy.

The accuser in her tweets had said that the #MeToo movement had encouraged her to come forward and that she had quit her job at Star India in the Airtime Sales section after 26 months and nine days and was now a homemaker, “taking care of my baby and hubby in a beautiful country, far away from Mumbai.”

The accuser said that while she was at the company, there were “clear instructions” given to make the sales team fulfil the targets in case they want to continue with their employment contract, “for which even if you have to take the clients to a hotel room and sleep with them for days.”

She said there were many instances when she and three of her female colleagues (interns) had clear instructions to reach a hotel after office hours for a private party hosted for influential friends.

She says the influential friends were “mostly bureaucrats and sometimes politicians and foreign nationals” who were “all ready to violate you, force you to dance against your wishes, drink with them, make drink(s) for them, exchange your numbers and even quietly accompany them to their respective rooms if they want you to”.

Veteran writer-director Vinta Nanda, who earlier this month accused actor Alok Nath of sexually violating her 19 years ago, wrote on Twitter: “I’m neither shocked nor surprised. I salute your courage to have come out and spoken out. The rot runs deep.” (IANS)
