Emisja rtęci z polskiej energetyki = Mercury emission from polish energy sector
PublicationEnergetyka jest głównym źródłem emisji rtęci- według krajowej inwentaryzacji emisji metali ciężkich. Jednak podawana emisja z elektrowni i elektrociepłowni spalających węgiel kamienny wydaje się być zawyżona. Najnowsze badania wykazują niższą zawartość rtęci w węglu kamiennym (50-150 ppb) niż w węglu brunatnym (120-370ppb). Istnieje zatem potrzeba weryfikacji stosowanych wskaźników emisji dla procesów spalania węgla, które służą...
