Additional information
Classification is triggered based on available data, according to REGULATION (EC) No 1272/2008 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL on classification, labelling and packaging of substances and mixtures, amending and repealing Directives 67/548/EEC and 1999/45/EC, and amending Regulation (EC) No 1907/2006. The values which triggers the classification is in the fish and daphnia and algal category.
Conclusion on classification
Classification of 3-chloroaniline for effects in the environment
Several major guideline – estimation values (Klimisch 2) are available for 3-chloroaniline, which indicates substantial toxic effect on all the three key trophic levels (fish, invertebrates and algae) when exposed to the substance, 3-chloroaniline at concentrations up to its limit of solubility in the respective test media. Among the values lower values which lead to the classification of the substance the value which have been considered for further calculation (fish) is LC50 = 0.147 mg/L.
In determining the classification appropriate to 3-chloroaniline, it is necessary to consider all available evidence concerning its persistence, potential to accumulate and predicted or observed environmental fate and behaviour that may present a long-term and/or delayed danger to the structure and/or functioning of aquatic ecosystems. These points are considered below.
Persistence
Reliable studies are available to demonstrate that 3-chloroaniline is non persistent in nature and so is considered to be biodegradable in the environment. In other words 3-chloroaniline may therefore be expected to degrade rapidly. Thus it can be inferred that 3-chloroaniline is non persistent.
Potential to accumulate
Predicted and measured log Kow values for 3-chloroaniline are less than 4 (Log Kow = 0.770). The potential for 3-chloroaniline to bioaccumulate in the tissues of organisms that inhabit aquatic or terrestrial matrices is negligible as, the BCF factor for the substance is less than 1000.
Classification is triggered based on available data, according to REGULATION (EC) No 1272/2008 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL on classification, labelling and packaging of substances and mixtures, amending and repealing Directives 67/548/EEC and 1999/45/EC, and amending Regulation (EC) No 1907/2006. The values which triggers the classification is in the fish and daphnia and algal category.
3-chloroaniline is non persistent and does not satisfy the criteria for classification as persistent (P).
The calculated BCF of 3-chloroaniline is 0.8 dimensionless and below the threshold of 2000.
3-chloroaniline does not satisfy the criterion for classification as bioaccumulative (B).
The toxicity values of fish, invertebrates and algae 0.147 mg/L, 0.26 mg/L are 0.74 mg/L, respectively. All the values of the 3 trophic levels fulfill the criteria for classification (0.1 to 1 mg/L) and so will qualify for classification as per the CLP regulation in the criteria of category 1 would be applicable.
3-chloroaniline does satisfy the environmental effects criterion for classification as toxic (T).
3-chloroaniline is therefore not a P & B (or vPvB) substance, but will qualify for T.
