Delhi’s Air Quality Remains “Severe” for Fourth Consecutive Day, Poses Serious Health Risks
Air pollution in Delhi has reached hazardous levels, with the Air Quality Index (AQI) remaining in the "severe" category for the fourth consecutive day. Areas such as Mundka, NSIT Dwarka, and Wazirpur recorded AQI levels well over 400, significantly impacting air quality. Key contributors to this pollution include vehicle emissions, industrial activity, dust from construction, and crop burning in neighboring states. Breathing in the toxic smog poses serious health risks, including respiratory irritation, chronic conditions like COPD, and increased vulnerability to asthma attacks. Health experts urge residents, particularly vulnerable groups, to limit outdoor activities and take protective measures like wearing masks and using air purifiers.
Why Does White Foam Continuously Form in the Yamuna River Unlike Other Rivers?
Excerpt on Toxic Foam in Yamuna River
A thick layer of toxic foam has formed on the Yamuna River near Kalindi Kunj in Delhi, leading the government to ban fishing in the affected areas due to high pollution levels. This foam, primarily caused by elevated phosphate concentrations from untreated sewage and industrial waste, poses serious environmental and health risks. Experts highlight that the foam's formation is exacerbated by the river's stagnant flow and the continuous discharge of pollutants, emphasizing the urgent need for effective pollution control measures to protect the river's ecosystem and nearby communities.
Difference between NIA, NSG, FSL, and what is the work of these three agencies?
On October 20, a bomb blast near the CRPF school in Rohini, Delhi, raised significant security concerns. Fortunately, there were no casualties or major damage. In response, the National Investigation Agency (NIA), National Security Guard (NSG), and Forensic Science Laboratory (FSL) are investigating the incident. The NIA, established after the 2008 Mumbai attacks, is the primary agency for investigating terrorism-related crimes and has the authority to operate across states without permission. The NSG, formed in 1984, specializes in counter-terrorism operations and high-profile security missions. Lastly, the FSL, with its roots dating back to 1952, conducts scientific investigations, analyzing evidence collected from crime scenes. While the NIA and FSL focus on investigative processes, the NSG is involved in direct field operations, highlighting the complementary roles of these agencies in enhancing national security.
Kosi River System’s Role in the Increasing Height of Mount Everest
A recent study published in Nature Geoscience reveals that the river network surrounding Mount Everest has contributed to its height, causing the mountain to rise between 15 and 50 meters over the past 89,000 years. Researchers from University College London found that the Arun River, which erodes a nearby gorge, is responsible for this uplift. The mountain currently rises by about 2 millimeters each year due to erosion, a process known as "isostatic rebound." This research sheds light on the geological processes affecting the Himalayas and emphasizes the significant role of river systems in shaping mountain landscapes.
