Jharkhand May Witness 5% Rise In Aerosol Pollution In 2023: Study

The study found that emission from thermal power plants was the main contributor to high aerosol amounts comprising particulate matter (PM2.5 and PM10), sea salt, dust, sulphate, black and organic carbon

Ranchi: Aerosol pollution is expected to rise by five per cent in Jharkhand next year, which may lead to a drop in visibility levels and pose a host of health problems for its citizens, a study by a premier research organisation said. Such pollution is likely to remain in the “highly vulnerable” red zone in the eastern state, it said. The study found that emission from thermal power plants was the main contributor to high aerosol amounts comprising particulate matter (PM2.5 and PM10), sea salt, dust, sulphate, black and organic carbon.

Kolkata-based Bose Institute’s associate professor of environmental sciences Dr Abhijit Chatterjee told PTI,

Rising aerosol pollution might aggravate asthma, lung and cardiovascular diseases. Children, women and elderly people might be the worst sufferers.

He also said, “Aerosol pollution is expected to rise by five per cent, pushing the AOD level over 0.6 within the vulnerable (red) zone in 2023.” Aerosol Optical Depth (AOD) is a quantitative estimate of the aerosol present in the atmosphere and it can be used as a proxy measurement of PM2.5.

Stating that Jharkhand currently falls under the red category, which indicates “high vulnerability with AOD over 0.5”, he said the long-term research was conducted by studying satellite-based data.

Mr Chatterjee and PhD scholar Monami Dutta from the same institute conducted the research- A deep insight into state-level aerosol pollution in India.

The increase in AOD in Jharkhand might seem negligible but the state is in the red zone. A little increase in the count would make the eastern state extremely vulnerable in the future.

The AOD at zero indicates a clear sky with maximum visibility, while the aerosol optical depth at 1 refers to very hazy conditions.

AOD value less than 0.3 falls under the green zone (safe), while a count between 0.3 and 0.4 refers to the blue segment (less vulnerable) and 0.4-0.5 in the orange category (vulnerable), while over 0.5 is the highly vulnerable red zone, the study said.

Ms Dutta, a senior research fellow at Bose Institute, explained,

Contribution of the thermal power plant (TPP) emission to aerosol pollution increased from 41 per cent in the 2005-2009 period to 49 per cent in 2015-2019. It is reflective of the increase in capacity of TPPs from 3,256 gigawatts (GW) to 7,531 GW in the period.

For Jharkhand, solid fuel burning is the second highest source, although its share reduced from 18 to 15 per cent from 2005-2009 to 2015-2019, the study found.

Vehicular emission is the next biggest contributor to aerosol pollution in the state.

Dr Chatterjee said,

Number of vehicles might have increased but engines have improved, particularly after the introduction of the BS-6 standard. So, vehicular pollution has reduced.

The study recommended that Jharkhand needs to achieve approximately 70-80 per cent reduction in TPP emission to reach a threshold AOD value of 0.4.

“This would mean that the state requires to reduce less than 5 GW thermal power generation capacity in order to move from the red zone to the blue one,” it suggested.

Asked about steps taken to reduce thermal power plant emission, Jharkhand State Pollution Control Board (JSPCB) chairman Sasikar Samanta said, “A state-level task force was recently constituted, which will draft a strategy to reduce the emission and phase out the plants.” He also mentioned that PCB authorities have been monitoring the thermal power plants whether these units are following the pollution control guidelines and standard operating procedure.

NDTV – Dettol have been working towards a clean and healthy India since 2014 via the Banega Swachh India initiative, which is helmed by Campaign Ambassador Amitabh Bachchan. The campaign aims to highlight the inter-dependency of humans and the environment, and of humans on one another with the focus on One Health, One Planet, One Future – Leaving No One Behind. It stresses on the need to take care of, and consider, everyone’s health in India – especially vulnerable communities – the LGBTQ population, indigenous people, India’s different tribes, ethnic and linguistic minorities, people with disabilities, migrants, geographically remote populations, gender and sexual minorities. In wake of the current COVID-19 pandemic, the need for WASH (Water, Sanitation and Hygiene) is reaffirmed as handwashing is one of the ways to prevent Coronavirus infection and other diseases. The campaign will continue to raise awareness on the same along with focussing on the importance of nutrition and healthcare for women and children, fight malnutrition, mental wellbeing, self care, science and health, adolescent health & gender awareness. Along with the health of people, the campaign has realised the need to also take care of the health of the eco-system. Our environment is fragile due to human activity, which is not only over-exploiting available resources, but also generating immense pollution as a result of using and extracting those resources. The imbalance has also led to immense biodiversity loss that has caused one of the biggest threats to human survival – climate change. It has now been described as a “code red for humanity.” The campaign will continue to cover issues like air pollution, waste management, plastic ban, manual scavenging and sanitation workers and menstrual hygiene. Banega Swasth India will also be taking forward the dream of Swasth Bharat, the campaign feels that only a Swachh or clean India where toilets are used and open defecation free (ODF) status achieved as part of the Swachh Bharat Abhiyan launched by Prime Minister Narendra Modi in 2014, can eradicate diseases like diahorrea and the country can become a Swasth or healthy India.
