Which city in India recorded the highest pollution levels in October 2025
According to the Finland-based Centre for Research on Energy and Clean Air (CREA),which city in India recorded the highest pollution levels in October 2025, with a monthly PM2.5 average of 123 µg/m³?
फिनलैंड स्थित सेंटर फॉर रिसर्च ऑन एनर्जी एंड क्लीन एयर (CREA) के अनुसार, भारत के किस शहर में अक्टूबर 2025 में सबसे अधिक प्रदूषण स्तर दर्ज किया गया, जिसमें मासिक PM2.5 औसत 123 µg/m³ था?
Detailed Solution & Logic
Dharuhera/ धारूहेड़ा
📊 Explanation :
According to the Finland‑based Centre for Research on Energy and Clean Air (CREA) Monthly Air Quality Snapshot for October 2025, Dharuhera in Haryana recorded the highest pollution levels in India with a monthly average PM2.5 concentration of 123 µg/m³. This was the worst among all Indian cities monitored that month, exceeding both national and safe air quality standards. All the top polluted cities were in the National Capital Region (NCR) and Indo‑Gangetic Plain, but Dharuhera led the list.
📌 Why this matters:
• PM2.5 refers to tiny fine particulate matter that can deeply penetrate lungs and enter the bloodstream — posing serious health risks like respiratory and heart diseases.
• An average of 123 µg/m³ is more than double India’s safe daily limit of 60 µg/m³ and far above the WHO guideline of 15 µg/m³.
🧠 Extra Facts:
• Despite not being as large or famous as Delhi or Noida, Dharuhera’s pollution was the worst in October 2025 — showing that industrial and local emissions can make smaller towns highly polluted.
• Delhi, often associated with extreme smog, came sixth in October (with about 107 µg/m³ PM2.5), but was still lower than Dharuhera’s average.
📖 व्याख्या
Finland आधारित Centre for Research on Energy and Clean Air (CREA) की अक्टूबर 2025 की एयर क्वालिटी रिपोर्ट के अनुसार भारत के सभी शहरों में धारूहेड़ा (हरियाणा) में PM2.5 प्रदूषण का मासिक औसत 123 µg/m³ दर्ज किया गया, जो सबसे अधिक था। यह मानक केवल राष्ट्रीय स्तर की सीमा से ही नहीं, बल्कि विश्व स्वास्थ्य संगठन (WHO) की सुरक्षा दिशा निर्देशों से भी बहुत ऊपर है।
📍 विशेष तथ्य:
• PM2.5 वे बहुत छोटे कण हैं जो हवा में लंबे समय तक तैरते रहते हैं और श्वास‑प्रश्वास के साथ गहरे फेफड़ों में प्रवेश कर सकते हैं, जिससे गंभीर स्वास्थ्य समस्याएँ हो सकती हैं।
• धारूहेड़ा, एक अपेक्षाकृत छोटा शहर होने के बावजूद, जिला‑स्तर के बड़े महानगरों जैसे दिल्ली और नोएडा से भी प्रदूषण में आगे निकला।
• दिल्ली ने अक्टूबर 2025 में लगभग 107 µg/m³ PM2.5 का औसत प्रदूषण दर्ज किया, लेकिन वह धारूहेड़ा से कम था।
