Description of key information

In an acute toxicity study to earthworms conducted to determine the effect of DPGDB (HLS 1998, VCL 259/972156), no mortalities were seen during the study, and all worms were normal in appearance on days 7 and 14 of the test. Under the conditions of this study, the LC50 value of DPGDB to the earthworm was found to be in excess of 1000 ppm. The no observed effect level (NOEL) was considered to be 1000 ppm.
