Delhi air quality to deteriorate further in next two days: Report

NEW DELHI: The air-quality of the national Capital is set to deteriorate further and become “very poor”, with the count of pollutants, especially the PM2.5, set to increase drastically.

According to the System of Air Quality and Weather Forecasting and Research (SAFAR), on Monday the PM2.5 concentration was recorded at 117 units, considered “poor” in per the Indian emissions standards.

This is, however, projected to increase to 128 units on Tuesday and 122 units on Wednesday, entering the category of “very poor”.

The SAFAR officials, however, claimed that the stubble burning in the neighbouring Punjab was not a major contributor to air pollution here.

“These reflections are due to fall in normal temperature and increase in humidity,” an official from SAFAR said.

PM2.5, or the particles in air with diameter less than 2.5mm, is one of the major and common pollutant with direct consequences on life expectancy. The international permissible limit for PM2.5 is 25 units while for India it is 60 units. “Major cause of the drop in the air-quality is because of increase in humidity and temperature fall. Stubble burning is a contributor but not a significant pollutant,” the official added.

On Monday, the Air Quality Index (AQI) in Delhi was recorded at 277 index value, considered “poor”, while in the neighbouring Ghaziabad it was already “very poor” at 302 index value. In Noida, however, the air-quality was found satisfactory, with AQI recorded at 62 index value. PM2.5 and PM10 were the major pollution contributors in Delhi. NEW DELHI: The phone of the murdered security guard Rakesh was missing from the crime scene giving police a probability that the killers would have walked away with his phone.

Moreover, the investigation revealed that the phone that 42- year-old Rakesh was using was switched off in the intervening night of Friday and Saturday when the five murders took place at Jindal Oil Mills in Mansarovar Park in Shahdara.

The cops are now focusing on the ‘why’ angle.

“Since every lead in the case is crucial, so a missing phone from the slain man is really a missing chain in investigation,” said a police officer privy to the investigation.

The police believes that the missing phone might have crucial details but since it is switched off the police is finding it difficult to track the location.

Meanwhile, the investigation has also revealed that the newly white washed house of the Jindals has no print marks of foot or hands if the killers tried to enter from outside suggesting a friendly entry.

“Its a newly white washed house, if you try to scale the walls it will definitely leave a mark. There is no mark on the walls,” said a police officer.

Cops are reluctant to believe it is a robbery attempt gone wrong and the Jindals have denied it has anything to do with the property dispute.

This makes the investigators believe that the motto of the intruders was killing the four women.

Since three of the four were suffering from ailments it make the investigators suspicious that someone who knew the condition of the ladies intruded the house and killed five people.

Cops are also looking into the call records of the close ones of the family, including the deceased to get some clue what happened on the fateful night.

Even the CCTV camera from the adjoing areas have been thoroughly scanned but no substantial clue was found.
