PM2.5 is finer than PM10, and yes, scientifically, it's more dangerous because it can get deep into your lungs and even enter your bloodstream. But bhai, let me tell you, I ignored those AQI warnings for years, saying 'kichu hobo ne'—until my maa's breathing troubles spiked every time the haze sat over Guwahati. That coarse PM10 dust from the construction near our flat? That's the one that actually, visibly hurts the people I love right now. So for me, the 'more dangerous' particle is the one you can see coating her windowsill.
