The matter was referred to the Committee by Germany under Article 35 of Directive 2001/82/EC, due to concerns that moxidectin may have persistent, bioaccumulative and toxic (PBT) properties, and consequently a potential serious risk to the environment may arise from the use of products containing the substance.

Persistent, Bioaccumulative, and Toxic (PBT) Chemicals: Technical Aspects, Policies, and Practices
Flame retardant chemicals such as HBCD (hexabromocyclododecane) and pentaBDE (pentabromodiphenyl ether) raise concerns for human health and the environment, including potential reproductive, developmental, and neurological effects and can be persistent, bioaccumulative, and toxic to aquatic organisms.
ECHA said in a statement that the substances of initial concern relate to risks to human health or the environment for "potential persistent, bioaccumulative, and toxic properties, suspected endocrine disruption or carcinogenic, mutagenic, and reprotoxic properties in combination with wide dispersive or consumer use.
An expert group has been set up by ECHA to help with the assessment of and validation of testing methods for chemicals suspected of being persistent, bioaccumulative and toxic (PBT) or very persistent and very bioaccumula-tive (vPvB).
