Feb 08, Kathmandu - Kathmandu Valley's air quality has deteriorated to an unhealthy level today, according to the Air Quality Index (AQI) measurements taken at 1:25 PM. The current AQI stands at 151, placing Kathmandu among the top ten most polluted cities globally.

Earlier this morning, Kathmandu was ranked as the seventh most polluted city in the world. Currently, it has slipped to the ninth position. Cairo in Egypt remains the most polluted city worldwide, with an AQI of 273.

The World Health Organization recommends an AQI below 35 for safe human health, with up to 50 considered normal. AQI levels above this are deemed harmful. An AQI between 51 and 100 signals caution, especially for vulnerable groups. Values from 101 to 150 can affect individuals with respiratory and heart diseases, while levels from 151 to 200 are considered unhealthy. AQI between 201 and 300 signifies very unhealthy air, and anything above 300 is considered hazardous.

According to Gyanraj Subedi, Director General of the Environment Department, dry weather, stagnant air, industrial operations, rapid construction, cross-border pollution, and pollution from neighboring India have contributed to the current situation. "Unless rain occurs, pollution levels are likely to increase further," he warned.

Subedi emphasized the need for environmentally friendly development and suggested measures such as stopping waste burning, increasing street cleaning with sweepers and vacuums, and issuing public advisories to protect children, the elderly, and patients.

The National Environment Policy 2076 outlines strategies to reduce pollution, including setting standards for water, air, soil, noise, electromagnetic waves, radioactive, and chemical pollutants. It also calls for establishing monitoring centers in major cities and industrial zones to regularly assess air, water, and noise quality.
