WHY IS COAL SO POLLUTING?

Coal produces a range of pollutants – notably carbon dioxide (CO2), a greenhouse gas. A lump of coal can contain between 60-80% carbon. The CO2 is produced when coal is burnt. Greenhouse gases build up in the earth’s atmosphere where they form a layer that traps heat, preventing it from escaping at night.

Burning coal also releases substances harmful to human health, like mercury, nitrogen oxides and Sulphur dioxides. Finally, there’s the particulate, or soot, that also disperses into the atmosphere. It is estimated that thousands of deaths every year can be attributed to these pollutants.

MENGAPA BATUBARA MENCEMARKAN?

Batubara menghasilkan berbagai polutan – terutama karbon dioksida (CO2), gas rumah kaca. Sebongkah batu bara dapat mengandung antara 60-80% karbon. CO2 dihasilkan ketika batubara dibakar. Gas rumah kaca menumpuk di atmosfer bumi di mana mereka membentuk lapisan yang memerangkap panas, mencegahnya keluar di malam hari.

Pembakaran batu bara juga melepaskan zat berbahaya bagi kesehatan manusia, seperti merkuri, nitrogen oksida, dan Sulfur dioksida. Akhirnya, ada partikulat, atau jelaga, yang juga menyebar ke atmosfer. Diperkirakan ribuan kematian setiap tahun dapat dikaitkan dengan polutan ini.
