Description of key information
The EC50 for growth rate is between 32-66.7 g/kg soil d.w.
Key value for chemical safety assessment
Additional information
On behalf of the VGB PowerTech e. V. the toxicity of ashes to plants was assessed by Roembke (2008) according to the ISO 11269-2 (1995). Different ashes (residues), coal types originated from combustion of hard coal or lignite with and without co-combustion, respectively, were tested. During an exposure period of 14 days the plant species Avena sativa and Brassica napus were exposed to different concentrations of ash in soil.
Both Avena sativa and Brassica napus tended to react most sensitive to the ashes (residues), coal with higher content of lime (FA 6). Under the test conditions of this study the EC50 for growth rate was not calculated but determined to lie between 32 and 66.7 g/kg soil d. w. for both test species Avena sativa and Brassica napus. Other studies with ashes (residues), coal with higher content of lime revealed an EC50 values between 66 and greater than 1000 g/kg. In general ashes (residues), coal without higher content of lime only caused mortality in plants at higher test concentrations. At concentrations up to 200 g ash/kg soil no growth reduction was observed. The most critical ashes (residues), coal was found to be a fly ash originated from combustion of hard coal (FA2). The EC50 of this ash is between 200 and 333.3 g/kg d. w. (FA5). Other ashes (residues), coal - fly ashes showed no or only slight growth reduction at the significant higher concentration of > 1000 g/kg soil d. w.
