Developed by the Indian Institute of Tropical Meteorology (IITM), Pune, a Decision Support System (DSS) that extends the ability of the existing air quality early warning system (AQEWS) to have decision-making capability for air quality management in Delhi-NCR was launched on Tuesday.
The website for the DSS (https://ews.tropmet.res.in/dss/) is designed to help the Commission for Air Quality Management for NCR and Adjoining Areas (CAQM) by delivering quantitative information about the contribution of emissions from Delhi and its 19 surrounding districts; the contribution of emissions from eight different sectors in Delhi; and the contribution from biomass-burning activities in the neighbouring states.
These information would assist in managing the air quality in a timely manner, a release from the Ministry of Earth Sciences said.
The need was stated by the CAQM, which was formed by the Ministry of Environment, Forest and Climate Change, during a meeting held in January 2021.
Recently, the Commission reviewed the progress made by IITM and had in principle approved the current version of DSS for air quality management in the Delhi-NCR. The IITM has also developed a new website for DSS with the entire system made operational, the release said.
Union Minister of State for Earth Sciences, Jitendra Singh, while launching the website for AQEWS on the occasion of 'Azadi Ka Amrit Mahotsav' week organised by the Ministry of Earth Sciences, said, "DSS is a significant contribution to 'Azadi Ka Amrit Mahotsav' on behalf of MoES and IITM and suggestions are invited on this issue."
The website also has a feature whereby the users can create their own emission reduction scenarios (from 20 different districts, including Delhi) so as to examine the possible projected improvement in air quality in Delhi for the next five days.
"This information would explicitly highlight the most important emission sources responsible for the degradation of air quality in Delhi and suggest possible solutions to ameliorate the same. With a plethora of quantitative data, the AQEWS integrated with DSS could become a user-friendly tool for air-quality management in and around Delhi," the release said. (IANS/JB)

The Centre has come out with draft regulations for extended producer responsibility (EPR) under Rule 9 (1) of the Plastic Waste Management Rules, 2016, wherein the EPR shall be applicable to both pre-consumer and post-consumer plastic packaging waste. The Plastic Waste Management Rules, 2016 mandate the generators of plastic waste to take steps to minimise generation of plastic waste, not to litter the plastic waste, ensure segregated storage of waste at source and hand over segregated waste to local bodies or agencies authorised by the local bodies. The rules also mandate the responsibilities of local bodies, gram panchayats, waste generators, retailers and street vendors to manage plastic waste.
The Ministry of Environment, Forest and Climate Change has invited comments from the stakeholders within 60 days of the publishing of the draft regulations, after which the final notification will be issued, said the Secretary in the ministry, R.P. Gupta. Extended producer responsibility (EPR) basically means the producer is responsible for the product till its very end of life and has to ensure reverse collection after the consumer has deemed it as waste.

The draft regulations cast EPR on producers, importers and brand owners for collection and recycling of plastic packaging waste and the EPR shall be applicable to both pre-consumer and post-consumer plastic packaging waste, according to the notification.
As reported by IANS in September, providing a framework for the implementation of EPR, the regulation set out the roles and responsibilities of producers, importers, brand owners, CPCBs/SPCBs/PCCs, recyclers and waste processors for effective implementation of EPR. Three kinds of plastic packaging categories have been identified to be covered under EPR: Rigid plastic packaging; Flexible plastic packaging of single layer or multilayer (more than one layer with different types of plastic), plastic sheets or like and covers made of plastic sheet, carry bags (including carry bags made of compostable plastics), plastic sachet or pouches; and multilayered plastic packaging (at least one layer of plastic and at least one layer of material other than plastic).
The manufacturer will be deemed responsible for managing the reversal from the consumer end and for recycling or treating plastic packaging waste. The notification also mentioned category-wise and year-wise targets for the producers. (IANS/ MBI)

There is no exaggeration in saying that Covid-19 has literally taken over our lives. Whether vaccinated or not, most of us are still living in the shadow of fear and anxiety. In fact with breakthrough infections showing up for some, even the vaccinated do not feel completely safe from a possible assault of the virus. The finding that the virus can be airborne is scary enough, research also shows that the transmission of the coronavirus is higher indoors than outdoors. This means that even if you don't step out and think that the virus can't get to you because you are ensconced safely and comfortably indoors, the bad news is that you can still get infected.
So, what should you do to keep the virus at bay while being confined indoors? While taking other precautions, keeping the indoor air sanitized, and constantly so, is one big answer to this.
Indoor aerosols a carrier of coronavirus
Unlike the earlier dominant belief that only respiratory droplets could spread infection, it has been established now that the tiny aerosols in the air can carry the coronavirus. These aerosols which are smaller and lighter than respiratory droplets can not only stay longer in the air but also carry the virus farther and for a longer time. The assumption that only by making contact with a contaminated surface one can get the virus, is no more valid.

Several natural human activities carried out Indoors
We must remember that a lot of our daily natural and basic activities are conducted in our indoor spaces many of which involve active and oral expulsion of particles. From talking to shouting to sneezing and coughing to even singing, every one of these acts and others creates aerosols in the air which whether we like it not, continue to be exchanged with the others. In fact, many of these activities create more aerosols than even breathing. So, if we do not repeatedly ventilate the room and purify the air within, we can always be susceptible to be infected by others. Even if a house has no Covid patient, the risk of the virus being transmitted through the air from the neighbours or temporary staff can never be ruled out.

Indoor air is naturally more unsafe than outdoor
As opposed to outdoor air which has natural circulation, unfortunately, indoor air doesn't have the same advantage. In India, the outdoor air itself isn't healthy enough for the human respiratory and health system due to the high amount of PM2.5, PM1.0 and other pollutants. So, without timely ventilation and purification, the chances of indoor air getting stale and unhygienic and thereby becoming more conducive to the 'designs' of coronavirus become very high. Add to this, there are recent studies that prove the possibility of PM2.5 particles being potential carriers of coronavirus, carrying them too much larger distances in the air. The high temperature and humidity which often characterizes our tropical climate add to the woes. (IANS/ MBI)

Children exposed to high levels of air pollution are up to 50 per cent more likely to self-harm later in life, suggested a study that adds to evidence of link between air pollution and mental health problems. Researchers from the University of Manchester in England and Aarhus University examined 1.4million kids under 10 in Denmark and found that those exposed to a high level of nitrogen dioxide were more likely to self harm in adulthood than their peers, the Daily Mail reported.
And people in the same age group exposed to above average levels of fine particulate matter (PM2.5) were 48 per cent more likely to subsequently self-harm, revealed the study published in the journal Preventive Medicine. Nitrogen dioxide is mainly produced by cars, while PM2.5 is mainly emitted by burning diesel and petrol, which is most commonly used for shipping and heating. These two pollutants are among those most commonly linked with causing harm to physical health, such as heart and lung diseases, by getting into the bloodstream and causing inflammation.
"Our findings add to the growing evidence-base indicating that higher levels of air pollution exposure are linked with poor mental health outcomes," lead author Dr Pearl Mok, a research fellow at Manchester University was quoted as saying. "Although air pollution is widespread, it is a modifiable risk factor and we therefore hope our study findings will inform policymakers who are devising strategies to combat this problem," Mok added.

While the researchers have not explained the mechanism for how these pollutants can cause mental health problems, they say high pollution levels could trigger inflammation in the brain, leading to mental health conditions, the report said. Childhood is a 'sensitive time for brain development', so youngsters may be 'particularly susceptible' to negative effects from toxic particles in the air, they added.
Further, the team found that some 32,984 people (2.3 per cent) harmed themselves in the study period, with cases higher among women, those whose parents had mental illness and individuals from poorer families. Exposure to an average of 19 microgram/m3 or more of particulate matter each day was associated with a 48 per cent higher chance of self-harming later in life, compared to children exposed to an average of 13 microgram/m3 per day or less. And for every 5 microgram/m3 increase in exposure above 19 microgram/m3, the risk of self harm rose by 42 per cent. (IANS/ MBI)
