1. Sulphur-Cleaning Device in Coal Plants Not Necessary Why in News? A government-appointed panel headed by the Principal Scientific Adviser (PSA) has suggested that Flue Gas Desulphurization (FGD) systems may not be needed in all coal-fired thermal power plants (TPPs). This comes despite a 2015 MoEFCC mandate requiring these devices to curb sulphur dioxide (SO₂)emissions. Key Points: • FGD Role: FGD systems reduce SO₂ emissions from flue gases in coal plants. • Current Situation: 92% of India’s 600 coal-based plants still don’t have FGDs. • Panel’s Justification: SO₂ levels in most Indian cities are within the permissible National Ambient Air Quality Standards (NAAQS). • Study Support: The recommendation is based on studies by NEERI, IITM, and IIT Delhi, which show SO₂ levels are within limits in 10–20 major cities. • Cost Factor: Installing FGDs increases capital costs and may lead to higher electricity tariffs. • Environmental Concern: Critics argue that SO₂, a contributor to acid rain and respiratory issues, can still pose a risk, especially in industrial zones. Timeline: • 2015: MoEFCC mandates emission norms including FGD installation in TPPs. • 2024: PSA-led expert panel recommends selective (not universal) implementation. Recent Developments & Improvements: • Expert committee reassesses the need for FGDs. • Data-driven evaluation of air quality trends used for policy suggestions. • Increased debate on balancing environmental goals with economic feasibility. UPSC Quick Facts: • FGD (Flue Gas Desulphurization): Captures SO₂ from exhaust gas in coal plants. • SO₂ Effects: Causes acid rain, PM2.5 formation, and respiratory issues. • Air (Prevention and Control of Pollution) Act, 1981: Legal basis for air quality regulation. • NAAQS: Set by the Central Pollution Control Board (CPCB) under the Air Act. • Principal Scientific Adviser (PSA): Advises the PM on scientific and technology policy. 2. Election Commission Launches Real-Time Voter Turnout System Why in News? The Election Commission of India (ECI) has launched a tech-driven system that allows real-time updates on voter turnout during elections. This step is aimed at improving transparency and addressing concerns about inconsistencies in earlier turnout figures. Key Points: • New System: Polling officers now upload voter turnout data every 2 hours using a mobile app or messaging services. • Manual Input: No sensor or automatic tools; officers input data via smartphone, SMS, or web interface. • Transparency Goal: Designed to ensure trust and reduce misinformation related to polling data. • Old System Flaws: Previous system relied on delayed, manual compilation—often leading to disputed figures. • Remote Area Support: The system includes offline and syncing capabilities for use in low-connectivity zones. Timeline: • May 2024: System used in Lok Sabha elections. • June 2025: Becomes part of ECINET – ECI’s internal digital network. Recent Developments & Improvements: • App-based digital reporting improves timeliness. • Reduces gap between preliminary and final turnout data. • Addresses allegations of turnout data mismatch raised by opposition parties. UPSC Quick Facts: • Article 324: Empowers ECI to supervise elections in India. • Election Commission of India: A constitutional body under Part XV of the Constitution. • ECINET: ECI’s secure internal data and communication network. • Voter Turnout: A critical indicator of democratic participation. • Use of Technology in Elections: Builds credibility, enhances transparency (e.g., EVMs, VVPAT, cVIGIL app). Bacteria Found at Rajgir Hot Spring Lake Shows Antimicrobial Activity Why in News? Scientists from Vellore Institute of Technology (VIT), Tamil Nadu, have discovered new antimicrobial compounds from thermophilic bacteria found in the Rajgir hot springs, Nalanda district, Bihar. The discovery is significant in the fight against Antimicrobial Resistance (AMR)—a growing global health concern. Key Points: • Discovery: Researchers isolated Actinobacteria (especially Thermus aquaticus) from Rajgir’s hot springs, identifying Diethyl phthalate as a compound with strong antimicrobial properties. • Hot Spring Ecosystem: Rajgir hot springs range from 25°C to 80°C. These extreme environments host thermophiles, or “heat-loving” bacteria, known for their unique biochemical traits. • Antimicrobial Testing: The extracted compound showed antimicrobial activity against major pathogens like: • E. coli, S. aureus, Pseudomonas aeruginosa, and Listeria monocytogenes. • Techniques Used: • DNA extraction • 16S rRNA gene sequencing • Culturing and bioactivity testing of isolated strains • Therapeutic Potential: The isolated compound may be used in future antibiotic development and even has shown preliminary relevance against COVID-19-related microbes. Timeline: • 2024–25: VIT conducted the research and shared findings recently. • Traditional Belief: Rajgir hot springs have been known for healing properties in Ayurveda for centuries. Recent Developments & Improvements: • Advanced Genomic Techniques: Use of molecular sequencing and bioinformatics for compound discovery. • Bioprospecting in Extreme Environments: Renewed scientific interest in unconventional ecosystems like hot springs for drug discovery. • Focus on AMR: As AMR becomes a global threat, natural sources are being re-examined for potential new antimicrobials.

A Ban, a Split Verdict, and a Health Concern Why in News? India imposed a ban on crude palm oil imports from Malaysia due to diplomatic tensions, raising concerns about adulteration in mustard oil with palm oil containing erucic acid, a potential health hazard. The “split verdict” points to differing views on palm oil blending and safety. Key Points: • Geopolitical Trigger: India’s import ban followed Malaysia’s comments on Kashmir and CAA, showing how trade policy can react to foreign diplomacy. • Adulteration Issues: • Blending of mustard oil with palm oil is being done for economic reasons. • Palm oil (especially unrefined) can contain erucic acid, which in high amounts may harm heart health. • Sold as “blended mustard oil,” it raises food safety concerns. • Health Risk - Erucic Acid: • A monounsaturated fatty acid linked to myocardial lipidosis in animal studies. • Human health impact is still uncertain; hence, precautionary principle is applied. • Policy Challenge: • The central government allowed oil blending on July 25, 2024, which is now being reconsidered. • Enforcement of FSSAI norms and preventing mislabeling/adulteration remain key concerns. • Economic Shift: • India reduced imports from Malaysia and pivoted to Indonesia, impacting the global palm oil market. Timeline: • July 2024: GOI permitted oil blending. • Late 2024 to Early 2025: Rising concerns and policy scrutiny over palm oil safety and trade ties. Recent Developments: • FSSAI and state bodies increasing inspections and testing. • Public health and consumer groups demanding clearer labeling on edible oils. • Heightened diplomatic awareness of trade retaliation. UPSC Quick Facts: • Palm Oil: India imports ~9 million tonnes annually, mostly from Southeast Asia. • Erucic Acid: EU limit – 5%; India’s permissible levels vary. • FSSAI: Statutory body under Ministry of Health & Family Welfare, established under FSS Act, 2006. • Geopolitics of Trade: Diplomacy-driven trade decisions (e.g., India-Malaysia palm oil, US-China tariffs). • Precautionary Principle: Act to prevent risk even if scientific evidence is incomplete. 5.
