Key value for chemical safety assessment
Additional information
The terrestrial compartment is not the primary environmental compartment affected by environmental emissions of the substance. Hydrogen peroxide occurs naturally in the environment, for example in rain water. In addition, hydrogen peroxide is continuously generated in physiological processes of the plants, for example in the mitochondria (e.g. Rasmusson et al. 1998). A complex system of enzymes, such as superoxide dismutase, ascorbate oxidase, catalase and glutathione peroxidase, exists in plants that scavenges reactive oxygen species like hydrogen peroxide (e.g. Mittler et al. 2004). There is evidence that hydrogen peroxide activates defence responses of plants to various environmental stresses (e.g. Bhattachrjee 2005, Neill et al. 2002). It has also been suggested that hydrogen peroxide at lower doses acts as a signal molecule during plant growth and development. From this it is concluded that terrestrial plants can cope with the levels of exposure to hydrogen peroxide that are to be expected from the identified uses of the substance. No additional testing is deemed necessary.
