- Across South Asia, average person would live five years longer if levels of fine particulate matter met WHO standards.
- PM2.5 pollution — 2.5 microns across or less, roughly diameter of human hair — penetrates deep into lungs and enters bloodstream.
- Worst-hit provinces include Henan and Hebei, in north-central China, and coastal province of Shandong.
PARIS: Microscopic air pollution caused mostly by burning fossil fuels shortens lives worldwide by more than two years, researchers reported Tuesday.
Across South Asia, the average person would live five years longer if levels of fine particulate matter met World Health Organization standards, according to a report from the University of Chicago’s Energy Policy Institute.
In the Indian states of Uttar Pradesh and Bihar, home to 300 million, crippling lung and heart disease caused by so-called PM2.5 pollution reduces life expectancy by eight years, and in the capital city of New Delhi by a decade.
PM2.5 pollution — 2.5 microns across or less, roughly the diameter of a human hair — penetrates deep into the lungs and enters the bloodstream.
In 2013, the United Nations classified it as a cancer-causing agent.
The WHO says PM2.5 density in the air should not top 15 microgrammes per cubic metre in any 24-hour period, or 5 mcg/m3 averaged across an entire year.
Faced with mounting evidence of damaging health impacts, the WHO tightened these standards last year, the first change since establishing air quality guidance in 2005.
“Clean air pays back in additional years of life for people across the world,” lead research Crista Hasenkopf and colleagues said in the Air Quality Life Index report.
“Permanently reducing global air pollution to meet the WHO’s guidelines would add 2.2 years onto average life expectancy.”
Major gains in China
Almost all populated regions in the world exceed WHO guidelines, but nowhere more so that in Asia: by 15-fold in Bangladesh, 10-fold in India, and nine-fold in Nepal and Pakistan.
Central and West Africa, along with much of Southeast Asia and parts of central America, also face pollution levels — and shortened lives — well above the global average.
Surprisingly, PM2.5 pollution in 2020, the most recent data available, was virtually unchanged from the year before despite a sharp slow-down in the global economy and a corresponding drop in CO2 emissions due to COVID lockdowns.
“In South Asia, pollution actually rose during the first year of the pandemic,” the authors noted.
One country that has seen major improvements is China.
PM2.5 pollution fell in the nation of 1.4 billion people by almost 40 percent between 2013 and 2020, adding two years to life expectancy.
But even with this progress, lives in China are on average cut short today by 2.6 years.
The worst-hit provinces include Henan and Hebei, in north-central China, and the coastal province of Shandong.
Compared to other causes of premature death, the impact of PM2.5 pollution is comparable to smoking tobacco, more than three times that of alcohol use, and six times that of HIV/AIDS, the report said.
Saudi crown prince MBS holds ‘frank, productive’ talks with Iranian foreign minister
- Talks held in cordial, frank atmosphere as relations are thawing.
- Agreement reached on the security, development of all in region.
- In last huddle Iranian side said things were moving on right track.
Saudi Arabian Crown Prince Mohammed bin Salman (MBS) Friday held discussions with Iran’s Foreign Minister Hossein Amirabdollahian, marking the most significant level of bilateral talks since their reconciliation in March, Reuters reported.
Taking place unexpectedly in Jeddah, this meeting occurred a day subsequent to Amirabdollahian’s arrival in Saudi Arabia.
Amirabdollahian had previously engaged in discussions with his Saudi counterpart, Prince Faisal bin Farhan, and expressed his belief that the relations between the two countries were “on the right track.”
“Discussions were frank, beneficial and productive,” Amirabdollahian said in a social media post after meeting MbS, adding that the countries “agree on the security and development of all in the region”.
Footage of the meeting on Iranian state media showed MbS and Amirabdollahian smiling as they spoke, while Prince Faisal and the Iranian delegation looked on. Saudi state news agency SPA said they discussed international and regional developments.
The rivalry between Iran’s revolutionary leaders and Saudi Arabia’s ruling family dominated the Middle East for years as they competed for influence in Iraq, Syria, Lebanon, Yemen and Bahrain amid a wave of sectarian bloodshed.
However, China brokered a rapprochement in March leading to a resumption of full diplomatic relations, which Saudi Arabia had broken off in 2016 when protesters attacked its Tehran embassy over Riyadh’s execution of a prominent Shi’ite cleric.
Prince Faisal visited Tehran in June and said he hoped Iranian President Ebrahim Raisi would visit the kingdom at the “appropriate time”.
After years of competition, and with some of the main regional arenas for their competition more stable than in previous years, both sides have reason to change tack.
Iran’s Supreme Leader Ayatollah Ali Khamenei wanted to end political and economic isolation pushed by the United States and saw new relations with Saudi Arabia as a way to do so, Iranian officials have said.
Saudi Arabia had meanwhile lost confidence in the US commitment to shared regional security concerns and wanted to bolster ties with China, which has retained good relations with Iran.
This month it succeeded in getting China to attend a diplomatic meeting on Ukraine that Beijing had earlier avoided.
Prince Faisal also spoke by phone with US Secretary General Antony Blinken, with the pair discussing more coordination to boost “security and stability in the Middle East region,” Saudi state media reported on Friday.
E-cigarettes as harmful as regular ones. Are there any alternatives?
Doctors are increasingly advising against the use of e-cigarettes, citing mounting evidence of their significant negative impact on health, even as a means to quit smoking.
Dr Petros Levounis, President of the American Psychiatric Association and Chair of the Department of Psychiatry at Rutgers New Jersey Medical School asserts that for current smokers, there are powerful, safe, and FDA-approved interventions available.
Recent medical guidelines from the American College of Cardiology, released in July, strongly discourage the use of e-cigarettes, particularly in individuals with chronic heart disease.
Dr Naomi Hamburg, a Cardiologist and Professor of Medicine at Boston University, highlights that even in young people, e-cigarettes have been shown to raise heart rate, and blood pressure, and disrupt blood vessel relaxation. Opting for a proven safe alternative is highly recommended.
While the FDA acknowledges that e-cigarettes may contain fewer harmful chemicals than traditional cigarettes, it maintains that no tobacco products are deemed safe.
Dr Jason Rose, a pulmonary and critical care physician, as well as an associate professor of medicine and associate dean for innovation and physician science at The University of Maryland School of Medicine, underscores that it is not possible to conclude that e-cigarettes are safer than cigarettes.
Doctors caution against a “dual use pattern,” where individuals attempting to quit smoking may turn to e-cigarettes in addition to traditional cigarettes.
This practice can have a particularly harmful combined effect on blood vessels, increasing the risk of heart disease, stroke, and other cardiovascular problems.
Frances Daniels, a parent and volunteer at Parents Against Vaping, shares the distressing story of her 17-year-old child who used e-cigarettes recreationally and ended up in the Intensive Care Unit for five weeks due to EVALI (e-cigarette or vaping product use-associated lung injury).
While Daniels’ child ultimately recovered without a lung transplant, the experience was agonizing.
For smoking cessation, doctors recommend sticking to FDA-approved products.
Options include Nicotine Replacement Therapy (NRT) like patches, gum, or inhalers, as well as medications such as Bupropion or Varenicline. Combining NRTs, like the patch and gum, is often suggested.
In some cases, psychosocial options such as cognitive behavioural therapy can be beneficial.
While e-cigarettes lack FDA approval as smoking cessation tools, companies continue to seek such approval.
The FDA insists that further research is needed to establish their safety for those seeking to quit tobacco cigarettes.
In the realm of smoking cessation tools, e-cigarettes are deemed less than ideal, with safer and scientifically proven alternatives available, according to Dr Hamburg.
Children among 6 killed in China kindergarten stabbing
- The 25-year-old suspect with surname Wi arrested.
- Media reports confirm children also among victims.
- Social media users demand capital punishment for stabber.
A stabbing rampage in a kindergarten in the Chinese province of Guangdong left at least six people dead and one injured, authorities said Monday, sparking fears about the safety of children’s schools.
The 25-year-old suspect with surname Wi was arrested and authorities have started an investigation into the stabbing.
According to media reports, the incident in Lianjiang County in the southern province was a stabbing, with some reporting that victims also include children.
While violent crime is rare in China due to strict gun laws and tight security, incidents of stabbings at pre-schools over the past few years have raised concerns about school safety.
The latest stabbing in China sparked emotive debate on the Weibo social media platform. By 1:50pm (0550 GMT) it was the top-trending discussion, with 290 million views.
Some social media users called for the suspect to face the death penalty.
“It’s outrageous to do this to children who have no power at all. How many families will be destroyed by this … I support the death penalty,” one Weibo user said.
Another user questioned security at schools, especially after similar previous attacks.
“Why do such cases still continue to emerge?”
Last year in August, at least three people lost their lives and six were injured in a stabbing at a kindergarten in the southern province of Jiangxi.
In 2021, a man killed two children and wounded 16 at a kindergarten in the southwestern region of Guangxi.
Attacks on children have also thrown a spotlight on mental health, which often goes under the radar due to the cultural stigma attached to mental illnesses.
In 2017, a 22-year-old man set off an explosive device outside a kindergarten in Jiangsu province, killing himself and a few others while wounding dozens.
According to state media, the man had a neurological disorder and scrawled words for death on the walls of his home.
Last month, a series of violent attacks in Hong Kong also raised the issue of mental health.
Mental health experts point to the COVID-19 pandemic as a major factor behind an increase in mental health problems.
