Penggunaan Abu Terbang Batubara Pada Pembuatan Batako Di Kota Palu [PDF]
, 2012 One cause of the poor quality of some concrete blocks in the city of Palu is the lack of cement used in the concrete block. This is caused by the high price of cement so that income of concrete blocks maker decreases. To find a way out of these problems,

Monitoring mercury across the National Wildlife Refuge System using a biosentinel approach
The Journal of Wildlife Management, EarlyView.We measured mercury concentrations in 1,356 dragonfly larvae collected from 30 National Wildlife Refuges across the United States and found wide variability among refuges, spanning the full range reported for other protected lands. Using a management‐focused mercury impairment index, 80% of refuges contained sites classified as moderate or higher risk.
