Sodium Chlorate
Type of composition:
legal entity composition of the substance
State / form:
solid: bulk
Reference substance:
Sodium Chlorate
PBT status:
the substance is not PBT / vPvB

The substance is readily biodegradable and has a logKow<-2.9, therefore does not meet the criteria for persistence (P) and bioaccumulation (B). For the T criterion, toxic effects were observed in long-term exposure for algae and aquatic plants, with EC10 values of 62.5 and 10 mg/L, respectively. As these values are greater than the T criterion of 0.01 mg/L, the substance is not classified as carcinogenic, mutagenic, or toxic for reproduction, and there is no other evidence of chronic toxicity, the substance does not meet the criterion for toxicity (T).


In conclusion, the substance could not be considered as a PBT or vPvB substance.
