AIR QUALITY INDEX (AQI)
1. Context
Factors like low wind speed and intrusion of smoke from stubble burning — added to the impact of local emissions.
This resulted in the air quality consistently worsening through the day from an average of 351 at 10 am to touch 402 at 5 pm. By 9 pm, it had deteriorated further to 418.
2. The Air Quality Index (AQI)
The AQI is a colour-coded index launched under the Swachh Bharat campaign to simplify the understanding of pollution levels. It helps convey the condition of the air and guides appropriate measures based on the severity of pollution. The AQI consists of six categories, each with a corresponding colour code: 'Good' (0-50), 'Satisfactory' (51-100), 'Moderately Polluted' (101-200), 'Poor' (201-300), 'Very Poor' (301-400) and 'Severe' (401-500).
3. Calculation of AQI
- To calculate the AQI, a technical study was conducted by an expert group, including medical professionals, air quality experts, and academics.
- Various pollutants, such as PM10, PM2.5, Nitrogen Dioxide, Ozone, Carbon, and others, are measured.
- Each pollutant is assigned a weight based on its impact on human health.
- The composite air quality index is determined by combining these weights, simplifying multiple data points into a single number and colour to represent overall air quality.
- Monitoring stations across the country assess these pollutant levels.
4. Impact of Pollutants on Health
- Among the most harmful pollutants are fine particulate matter, such as PM2.5, which has a diameter smaller than 2.5 micrometres.
- PM2.5 particles can easily enter the circulatory system, bypassing the nose and throat.
- They are associated with respiratory problems and reduced visibility, posing health risks such as asthma, heart attacks, bronchitis, and other respiratory issues.
5. Influence on Government Policy
- Governments, especially in areas like Delhi, use the AQI to announce measures to combat air pollution.
- When the AQI in the National Capital Region (NCR) reaches the 'severe' category, Stage 4 of the Graded Response Action Plan (GRAP) is implemented.
- GRAP is designed for emergency measures to prevent further deterioration of air quality.
- Specific actions may include prohibiting the use of non-BS-VI-compliant diesel four-wheelers and restricting the entry of trucks into the city while allowing petrol cars to continue operating as usual.
6. Conclusion
The Air Quality Index is an essential tool that simplifies the understanding of air pollution, assesses its health impacts, and influences government policies and actions to combat deteriorating air quality. As Mumbai braces for worsening air quality, the AQI will continue to be a critical resource for both the government and the public.

(CAR) T CELL THERAPY
- Chimeric Antigen Receptor (CAR) T-cell therapy is a revolutionary form of immunotherapy used to treat certain types of cancer, primarily blood cancers like leukaemia and lymphoma. This innovative approach harnesses the power of a patient's own immune system to target and destroy cancer cells
- CAR T-cell therapy has shown remarkable success in treating certain blood cancers, particularly in cases where other treatments have failed. However, it is not without potential side effects, including cytokine release syndrome (CRS) and neurologic toxicity, which can be severe in some cases
- Two well-known CAR T-cell therapies that have received approval from regulatory agencies like the U.S. Food and Drug Administration (FDA) are Kymriah (tisagenlecleucel) and Yescarta (axicabtagene ciloleucel), used to treat certain types of leukemia and lymphoma. Research and development in this field are ongoing, with efforts to expand the application of CAR T-cell therapy to other types of cancers and improve its safety and effectiveness
- A patient's own T-cells (a type of immune cell) are collected from their blood through a process called leukapheresis
- The collected T-cells are then genetically engineered in a laboratory to express a chimeric antigen receptor (CAR) on their surface. This CAR is designed to specifically recognize a particular protein or antigen found on the surface of cancer cells. This engineering process enables the T-cells to target cancer cells more effectively
- The expanded CAR T-cells are infused back into the patient's body through an intravenous (IV) infusion
- Once in the patient's body, these CAR T-cells seek out and bind to cancer cells that express the target antigen. This binding activates the T-cells, leading to the destruction of the cancer cells
ELECTORAL BOND SCHEME
1. Context
The recent dismissal of petitions seeking to halt the sale of electoral bonds by the Supreme Court has reignited debates over the use of these instruments in Indian politics. Electoral bonds, introduced in the 2017 Union Budget, allow donors to make anonymous contributions to political parties. This article delves into the issues surrounding electoral bonds and the pending constitutional challenge against them.
2. The Pending Challenge
- The challenge against electoral bonds was initiated in 2017 by the Association for Democratic Reforms and Common Cause, non-profit organizations advocating for electoral transparency.
- The case questions the constitutionality of the electoral bonds scheme and seeks to bring political parties under the ambit of the Right to Information Act, compelling them to disclose their income and expenditure.
- Although the Supreme Court has rejected a plea to suspend the sale of electoral bonds, the larger constitutional challenge remains pending.
- The court admitted the petition and solicited responses from the government and the Election Commission of India (EC). However, the case has not yet received in-depth consideration.
3. About Electoral Bonds
The electoral bonds scheme is a mechanism for political funding introduced by the Indian government in 2017. It allows individuals, organizations, and corporations to make anonymous donations to political parties. Over 12,900 electoral bonds worth Rs 6,534.78 crore were sold in 15 phases between March 2018 and January 2021.
3.1. Key Features of Electoral Bonds
- Electoral bonds allow donors to make contributions to political parties while maintaining anonymity. The bonds do not carry any information about the donor, ensuring that the identity of the contributor remains undisclosed.
- Electoral bonds are available in multiple denominations, including Rs 1,000, Rs 10,000, Rs 1 lakh, Rs 10 lakh, and Rs 1 crore. Donors can purchase bonds in these denominations to contribute to political parties.
- The State Bank of India (SBI) is the sole authorized bank for the sale of electoral bonds. Donors can buy these bonds from designated SBI branches.
- Donors must fulfil Know Your Customer (KYC) norms while purchasing electoral bonds, which includes providing their personal information to the bank. However, this information is not disclosed to the political party receiving the donation.
- Political parties have 15 days to encash the electoral bonds in their verified bank accounts. This ensures that the bonds are promptly converted into funds.
- There is no limit on the number of electoral bonds an individual or company can purchase, allowing for substantial contributions.
- If a political party does not encash the electoral bonds within the stipulated 15-day period, the SBI deposits these bonds into the Prime Minister's Relief Fund.
- A contentious feature of the scheme is that political parties receiving donations through electoral bonds are exempt from disclosing the source of these donations in their mandatory annual contribution reports to the Election Commission of India (EC).
3.2. Rationale Behind the Electoral Bonds Scheme
The rationale for introducing the electoral bonds scheme was as follows:
- Proponents of the scheme argued that it would bring a level of transparency to political funding by making contributions through a banking channel, as all transactions would go through the banking system, leaving an audit trail.
- The scheme was intended to protect the privacy of donors, allowing individuals and entities to contribute to political parties without fear of retribution or public exposure.
- By providing a legal and transparent means for making political contributions, the scheme aimed to reduce the use of unaccounted-for cash in political funding, which was perceived as a major source of corruption in the political process.
- The scheme encouraged donors to make contributions through the formal banking system, thereby promoting digital transactions and aligning with the government's push for a cashless economy.
3.3. Challenges and Controversies
- The primary point of contention with electoral bonds is the anonymity they offer to donors.
- An amendment to the Finance Act 2017 exempts parties from disclosing donations received through these bonds.
- This means that voters are unaware of the source and extent of funding for political parties, undermining transparency.
- Transparency activists argue that the amendment infringes upon the citizen's 'Right to Know' and further reduces the accountability of the political class.
- While the citizens remain uninformed, the government can access donor details from the State Bank of India, rendering only the taxpayers unaware of the source of donations.
| Electoral bonds have gained popularity due to the anonymity they offer to donors. More than half of the total income of national and regional parties in the financial year 2018-19 came from electoral bond donations. The Bharatiya Janata Party (BJP) emerged as the largest beneficiary, receiving 60.17% of the total electoral bond donations. |
4. Election Commission's Stand
The Election Commission has expressed objections to amendments in the Representation of the People Act that exempt political parties from disclosing donations via electoral bonds. It has raised concerns about the potential violation of provisions prohibiting political parties from receiving donations from government companies and foreign sources.
