Geochemistry of trace elements as one of the important coal quality parameter: an example from Balingian Coal, Malaysia
Ash and sulphur are the two main variables that influence coal quality and are therefore very important contractual parameters in a coal supply agreement. Coal which is low in ash yield and sulphur content is considered as ‘cleaned coal’. Nonetheless, combustion of coal is also known to release toxi...

| description | Ash and sulphur are the two main variables that influence coal quality and are therefore very important contractual parameters in a coal supply agreement. Coal which is low in ash yield and sulphur content is considered as ‘cleaned coal’. Nonetheless, combustion of coal is also known to release toxic trace elements, which are known or suspected to be carcinogenic and may also cause respiratory problems, pregnancy complications, premature mortality and possibly a wide range of health problems. The two traditionally used coal quality parameters have proven to be insufficient for defining ‘cleaned coal’. This is evidenced by the low ash and low sulphur Balingian coals that is seen as relatively safe in environmental terms, but still contains high concentrations of potentially hazardous trace elements which may pose health and environmental threats during coal combustion. Therefore, a comprehensive assessment of coal quality should also include information on concentration, spatial distribution and modes of occurrence of trace elements, particularly the 15 potentially hazardous trace elements identified by the United States Clean Air Act Amendments (1990). |
