is mildly irritating to
the eyes
and
the skin
.
Effects of Long-Term or Repeated Exposure:
The substance may have effects on the
liver
, resulting in
liver impairment
.

Environmental
Data
|
Bioaccumulation of this chemical may occur along the food chain, for example in crustacea.
In the food chain important to humans, bioaccumulation takes place, specifically in fish.
It is strongly advised not to let the chemical enter into the environment because it persists in the environment.
The substance may cause long-term effects in the aquatic environment.
