Gulf storm played bigger role in Delhi air pollution

Agencies
November 17, 2017

New Delhi, Nov 17:  A West Asian dust storm has been identified as the chief trigger behind the recent air pollution crisis in Delhi.

While stubble burning was said to be a key cause for the toxic smog in the national capital, prompting a spat between Delhi government and governments of neighbouring states, a Centre-run monitoring agency said the particulates from the dust storm that entered the upper atmospheric layer of Delhi and the larger region also contributed to a spike in air pollution levels.

On November 8, the contribution of the dust storm was 40 per cent, eclipsing the role of emissions from stubble burning, which stood at 25 per cent, the Pune-based System of Air Quality And Weather Forecasting And Research (SAFAR) said.

That was the day pollution levels peaked with PM2.5 concentration reaching 640 micrograms per cubic metre, according to the SAFAR scientific assessment report of the week-long pollution crisis accessed by news agency.

"Rest was made up of emissions from local sources such vehicular combustion. If external sources did not have any role, levels of PM2.5 during this period could have been around 200 micrograms per cubic metre," the report has stated.

Uptick in air pollution levels prompted Aam Admi Party led Delhi government to impose a swries of emergency measures in the national capital such as a ban on the entry of trucks and construction activities yielded positive results, the agency said, putting the gains at around 15 per cent in terms of percentage.

PM2.5 are ultrafine particulates, up to 30 times finer than a width of a human hair, which can lodge deep in the lungs and enter the bloodstream, causing irreparable harm to living beings.

The 24-hour prescribed standard of this variety of suspended particulate matter is 60 micrograms per cubic metre.

SAFAR, an arm of the Indian Institute of Tropical Meteorology, said particulates from the dust storm, which swept across Iraq, Kuwait, and Saudi Arabia between the last week of October and November 4, entered the upper atmospheric layer of Delhi and the larger region.

Moreover, according to the report, stubble burning in Punjab, Uttar Pradesh and Haryana were very high on November 6 and as upper air winds became North Westerly (towards Delhi), pollutants were strongly pumped in, exacerbating the situation.

"As per SAFAR forecasting model, the pollution contribution of Gulf Dust Storm on peak day (8th Nov 2017) was around 40 per cent and 25 per cent from stubble burning," the report said.

Till about November 6, the mean PM2.5 level remained between 140-190 ug/m3, usual for this time of the year, SAFAR, the only agency which puts out pollution forecast bulletins in India, said.

Subsequently, from around November 10, there was no pumping of dust from West Asia. Influence of stubble burning also came down as upper air winds slowed down and changed direction, resulting in a brief respite from pollution.

"However, localized weather took over by the evening of November 11. Before pollutants could be flushed, inversion layer (beyond which pollutants cannot escape) fell down from 1600 metres to just 45 metres in eight hours and Delhi entered the severe zone again which delayed full recovery by two days," SAFAR said.

Mangaluru, Dec 3: A group of Congress workers gathered at the Mangaluru International Airport on Wednesday to welcome AICC general secretary K C Venugopal, but the reception quickly turned into a display of support for Deputy Chief Minister D K Shivakumar.

Venugopal arrived in the city to participate in the centenary commemoration of the historic dialogue between Mahatma Gandhi and Narayana Guru. The event, organised by the Sivagiri Mutt, Varkala, in association with the Mangalore University Sri Narayana Guru Study Chair, is being held on the university’s Konaje campus.

KPCC general secretary Mithun Rai and several party workers had assembled at the airport to receive Venugopal. However, the moment he stepped out, workers began raising slogans backing Shivakumar.

The university programme will be inaugurated by Chief Minister Siddaramaiah.

This show of support comes just a day after Siddaramaiah remarked that Shivakumar would lead the government “when the high command decides.” The chief minister made the comment after a breakfast meeting at Shivakumar’s residence—another public display of camaraderie between the two leaders amid ongoing attempts by the party high command to downplay their leadership rivalry.

Israeli forces have pushed over the Syrian frontier, erecting a checkpoint and stopping vehicles in the southwestern city of Quneitra, in yet another breach of the Arab country’s sovereignty.

The violation took place on Sunday, when the troops made their way across the border, setting up the outpost near the Ain al-Bayda junction in northern Quneitra, Syrian outlets reported.

According to the al-Ikhbariya paper, an Israeli detachment positioned itself at the junction, halting cars and conducting searches.

The Syrian Arab News Agency (SANA) reported that three Israeli military vehicles then moved further into the northern countryside, deploying between the town of Jubata al-Khashab and the villages of Ofaniya and Ain al-Bayda. The agency added that a separate Israeli unit mounted a new incursion in the central region, approaching the villages of Umm Batina and al-Ajraf.

Residents said such activities have surged in recent months, pointing to Israeli advances onto farmland, leveling of extensive forested areas, arrests, and spread of mobile checkpoints.

The Israeli regime began markedly increasing its military aggression against Syria last year.

The escalation coincided with increasingly ferocious onslaughts throughout the country by the so-called Hay'at Tahrir al-Sham (HTS) Takfiri terrorist group, which the government of President Bashar al-Assad had confined to northwestern Syria. The HTS, however, managed to overthrow the government as the Israeli attacks would pummel the country’s civilian and defensive infrastructure.

Various reports have shown that, during the escalation, the regime conducted more than 1,000 airstrikes on the Syrian territory and over 400 ground raids into the south.

Following the collapse of the Assad government, Tel Aviv also widened its grip over the occupied Golan Heights by taking control of a demilitarized buffer zone, in defiance of a 1974 Disengagement Agreement. Earlier this month, senior Israeli officials, including Prime Minister Benjamin Netanyahu, visited the buffer zone, prompting expressions of alarm on the part of the United Nations.

The United States, the regime’s biggest ally, has, meanwhile, been fraternizing the HTS head Abu Mohammed al-Jolani amid the widely reported prospect of rapprochement with Tel Aviv.

Local authorities say the Israeli military has expanded the so-called “yellow line” truce demarcation in Gaza City and repositioned its forces deeper into the territory in violation of a ceasefire agreement that came into force on October 10, besieging dozens of Palestinian families.

Gaza’s Government Media Office announced in a statement on Thursday that Israeli forces widened the boundary by shifting the markers, and advanced roughly 300 meters (984 feet) into the neighborhoods of Ash-Shaaf, An-Nazzaz and Baghdad Street.

The move pushed further into civilian areas, trapping families who were unable to flee as tanks rolled forward, it added.

“The fate of many of these families remains unknown amidst the shelling that targeted the area,” the office said, adding that the expansion of the yellow line shows a “blatant disregard” for the ceasefire deal.

On Friday, sources said the Israeli military carried out continued air and artillery strikes inside the so-called “yellow line” east of Khan Younis in the southern Gaza Strip.

According to the reports, Israeli warplanes and tanks targeted areas within the zone. One Palestinian was reported killed and several others wounded in the strikes, the sources said.

The fresh aggression came only a day after 25 Palestinians were killed in Israeli airstrikes on Gaza City and Khan Younis on Wednesday.

The media office reported that Israel has consistently violated the truce deal since its implementation last month, with near-daily attacks by air, artillery and direct shootings.

The office said over 400 violations have been documented. These breaches have resulted in the deaths of more than 300 Palestinians and left hundreds injured.

The Government Media Office in Gaza urged the guarantors of the ceasefire — the US, Egypt, Qatar and Turkey — to take swift action to halt the ongoing violations and facilitate the delivery of food, shelter materials, medical aid, and infrastructure equipment.

The so-called “yellow line,” set out in the agreement between Israel and Hamas resistance movement, refers to a non-physical partition where the Israeli military repositioned itself when the truce deal took effect.

It has allowed Israel, which routinely fires at Palestinians who approach the line, to retain control over more than half of the Gaza Strip.

International bodies, including the UN Independent International Commission of Inquiry, the International Association of Genocide Scholars, Amnesty International, Human Rights Watch, B’Tselem, and other rights groups, have concluded that the Israeli war on Gaza amounts to genocide.

In the attacks in Gaza since October 2023, Israel has killed at least 69,546 people and injured 170,833 others, leveling large swaths of the territory and displacing almost all of the population.
