काठमाडौं — काठमाडौं उपत्यकामा वायु प्रदूषण बढ्दै गएको छ। विश्वभर वायु प्रदूषणको अवस्था मापन गर्दै आएको स्विट्जरल्यान्डस्थित आईक्यूएयरका अनुसार काठमाडौं वायु प्रदूषणको दृष्टिले विश्वकै तेस्रो स्थानमा पुगेको छ।
विश्वमै अस्वस्थकर वायुको पहिलो स्थानमा भारतको नयाँदिल्ली छ भने दोस्रो स्थानमा थाइल्याण्डको चिङ्गमाई शहर छ।
चीनको बेइजिङ विश्वकै प्रदूषित शहरको सूचीको १५औँ नम्बरमा छ।
सोमबार बिहान काठमाडौंको वायु गुणस्तर सूचकांक (एक्यूआई) १७३ रहेको छ। १५१ देखि २०० एक्यूआई गुणस्तरको वायुलाई अस्वस्थकर मानिन्छ। आईक्यूएयरले अस्वस्थकर वायुलाई रातो रंगले चित्रित गर्ने गरेको छ।
विश्वमै सबैभन्दा प्रदूषित नयाँदिल्लीको एक्युआई २४४ छ। यो अत्यन्तै अस्वस्थकर वायुको अवस्था हो। २०१ देखि ३०० सम्म एक्यूआईलाई अत्यन्तै अस्वस्थकर मानिन्छ।
एक्यूआईले हावामा हुने पीएम २.५ र पीएम १० भनिने सूक्ष्म कणलाई हेरेर प्रदूषणको तह निर्धारण गर्छ। वायुको अवस्था जनाउने सूचक १०० भन्दा माथि पुगेमा स्वास्थ्य कमजोर भएकाहरूका लागि अस्वस्थकर र १५० अंकभन्दा माथि पुगेमा सबैलाई अस्वस्थकर मानिने विज्ञहरू बताउँछन्।
हरेक वर्ष चैतको बेला काठमाडौं उपत्यकामा वायु प्रदूषण बढ्ने गरेको छ। काठमाडौं उपत्यकामा बिहान र बेलुकाको समयमा वायु प्रदूषण अत्यधिक बढ्ने गरेको विज्ञहरूको भनाई छ।
वायु प्रदूषणले जनस्वास्थ्यमा नकारात्मक असर पर्ने चिकित्सकहरूले बताएका छन्। विशेषगरी बालबालिका, वृद्धवृद्धा एवं श्वासप्रश्वाससम्बन्धी बिरामी र मुटुका बिरामी यसबाट बढी प्रभावित हुने गरेका छन्।
प्रदूषणको बेला सकेसम्म घरबाहिर ननिस्किन र निस्कनुपरे पनि विशेष सावधानी अपनाउन चिकित्सकहरूले सुझाव दिएका छन्।
