C.I. Pigment Yellow 34

CAS Registry Number 1344-37-2

What is it?

  • C.I. Pigment Yellow 34 is an industrial chemical.

How is it used?

  • C.I. Pigment Yellow 34 is mainly used for export and commercial, non-consumer uses, such as an additive for paints and coatings, printing inks and in plastics.
  • It is also used in traffic paint striping to improve safety/visibility for highways and airports, and for safety identification paints on buses, ambulances and fire trucks.
  • C.I. Pigment Yellow 34 can also be found in industrial paints for automotive finishes, industrial and agricultural equipment, industrial baking enamels and air-dried finishes.
  • Based on the most recent data available, C.I. Pigment Yellow 34 is manufactured in and imported into Canada.

Why did the Government of Canada assess it?

  • C.I. Pigment Yellow 34 was identified as a potential concern to human health based on its classification by an international organization as a substance that may cause cancer, which might impair fertility, and which might also cause developmental problems.
  • C.I. Pigment Yellow 34 was also believed to have a high potential for exposure to Canadians.
  • C.I. Pigment Yellow 34 was assessed by Government of Canada scientists to help decide if further actions might be necessary so that the health of Canadians and the environment are protected.

How are Canadians exposed to it?

  • There were no reports of current uses in consumer products. As a result, exposure of the general population in Canada to C.I. Pigment Yellow 34 is expected to be very low.

What is the Government of Canada doing?

  • The Government of Canada has conducted an evaluation of C.I. Pigment Yellow 34 based on science, called a screening assessment.
  • The Government of Canada has determined that C.I. Pigment Yellow 34 is considered to be harmful to human health.
  • Although Canadians' exposure is very low, the Government of Canada is taking action so that exposure remains low.
  • Risk management options include the development of a future notification tool so that new uses in Canada do not increase exposure for Canadians.
  • The Government of Canada will phase out the use of pavement marking paints containing C.I. Pigment Yellow 34 after December 31, 2010 according to the Surface Coating Materials Regulations of the Hazardous Products Act.
  • The final screening assessment report and proposed risk management approach document were published on January 31, 2009. The proposed risk management approach will be subject to a 60-day public comment period ending April 1, 2009.

What should Canadians do?

  • Because exposure to C.I. Pigment Yellow 34 is very low, Canadians do not need to take any specific actions to reduce their exposure.
