Chemical name: 6,9-Methano-2,4,3-benzodioxathiepin, 6,7,8,9,10,10-hexachloro-1,5,5a,6,9,9a-hexahydro-, 3-oxide

Final regulatory action has been taken for the category: Pesticide

Final regulatory action: The chemical is Banned

Use or uses prohibited by the final regulatory action:

All applications

Pesticide use or uses that remain allowed:

None

The final regulatory action was based on a risk or hazard evaluation: Yes

Summary of the final regulatory action:

It is prohibited to sell, stock, store or use endosulfan as pesticide

The reasons for the final regulatory action were relevant to: Environment

Summary of known hazards and risks to the environment:

Application (according to good agricultural practice) of endosulfan will result in surface water concentrations that will significantly affect aquatic organisms (especially fish). Emission of endosulfan to surface water will be due to spraying drift during application (fruit). The surface water concentration of endosulfan during application was estimated with a dispersion model. Assuming a drift emission factor of 10%, an endosulfan concentration of 0.014mg/l was calculated. Comparing this concentration with the lowest LC50 for fish (0.00017mg/l) results in a risk quotient of 82 which was considered unacceptable. Field experiments in Africa support these conclusions.

Evaluation is based on a review of scientific data in the context of the conditions prevailing in the country.

Expected effect of the final regulatory action in relation to the environment:

Complete risk reduction.

Date of entry into force of the final regulatory action: 01/01/1990
