المسند يوضح المقصود بـ "الهباء الجوي" وكيفية نشأته.. ويكشف عن الجزئيات الأخطر على الرئتين
5 ي 9 1

صحيفة المرصد: كشف أستاذ المناخ الدكتور عبدالله المسند، دخول موسم العقرب الثانية، عن المقصود بالهباء الجوي وكيفية نشأته، والجزئيات الأخطر على الرئتين.

رماد البراكين

وقال المسند عبر حسابه على منصة إكس: الهباء الجوي (Aerosol) هو عبارة عن جزيئات دقيقة جدًا صلبة تكون معلقة في الهواء، وهي تنشأ من: الغبار، رماد البراكين، حبوب اللقاح، دخان الحرائق الطبيعية، عوادم السيارات، الدخان، الأتربة الناتجة عن البناء والزراعة، المصانع، الرش بالمبيدات، بقايا حشرية، وباقيا من جلد الإنسان المتساقط.

الجزيئات 

وتابع، قائلاً:"ويبلغ حجم الجزيئات من 0.001 ميكرومتر إلى 100 ميكرومتر تقريبًا .. والجزيئات التي يقل حجمها عن 2.5 ميكرومتر (PM2.5) تُعد الأخطر لأنها تدخل بعمق إلى الرئتين".
