The DNELs for local inhalation effects are based on the corresponding DNELs that are available for hydrogen peroxide, taking into account that:
a) according to the stoichiometry of the hydrolysis reaction of magnesium peroxide, an equimolar amount of hydrogen peroxide is formed; and that
b) the reaction mass of magnesium carbonate and magnesium hydroxide and magnesium oxide and magnesium peroxide typically contains 37% of magnesium peroxide.
Worker – inhalation – local effects – long term
DNEL (hydrogen peroxide): 1.4 mg/m3
a) stoichiometrie
1.4 mg hydrogen peroxide = 4.116E-05 mol hydrogen peroxide
= 4.116E-05 mol magnesium peroxide
4.116E-05 mol magnesium peroxide = 2.3 mg magnesium peroxide
DNEL (magnesium peroxide) = 2.3 mg/m3
b) composition of reaction mass
DNEL (magnesium peroxide) = 2.3 mg/m3
DNEL (reaction mass) = 6.2 mg/m3
The worker long-term DNEL for local effects following inhalation of the reaction mass of magnesium carbonate and magnesium hydroxide and magnesium oxide and magnesium peroxide is:
DNEL (reaction mass) = 6.2 mg/m3
Worker – inhalation – local effects – short term
DNEL (hydrogen peroxide): 3.0 mg/m3
a) stoichiometrie
3.0 mg hydrogen peroxide = 8.821E-05 mol hydrogen peroxide
= 8.821E-05 mol magnesium peroxide
8.821E-05 mol magnesium peroxide = 5.00 mg magnesium peroxide
DNEL (magnesium peroxide) = 5.00 mg/m3
b) composition of reaction mass
DNEL (magnesium peroxide) = 5.00 mg/m3
DNEL (reaction mass) = 13.4 mg/m3
The worker short-term DNEL for local effects following inhalation of the reaction mass of magnesium carbonate and magnesium hydroxide and magnesium oxide and magnesium peroxide therefore is:
DNEL (reaction mass) = 13.4 mg/m3

General population – inhalation – local effects – long term
DNEL (hydrogen peroxide): 0.21 mg/m3
a) stoichiometrie
0.21 mg hydrogen peroxide = 6.174E-06 mol hydrogen peroxide
= 6.174E-06 mol magnesium peroxide
6.174E-06 mol magnesium peroxide = 0.35 mg magnesium peroxide
DNEL (magnesium peroxide) = 0.35 mg/m3
b) composition of reaction mass
DNEL (magnesium peroxide) = 0.35 mg/m3
DNEL (reaction mass) = 0.94 mg/m3
The general population long-term DNEL for local effects following inhalation of the reaction mass of magnesium carbonate and magnesium hydroxide and magnesium oxide and magnesium peroxide is:
DNEL (reaction mass) = 0.94 mg/m3
General population – inhalation – local effects – short term
DNEL (hydrogen peroxide): 1.93 mg/m3
a) stoichiometrie
3.0 mg hydrogen peroxide = 5.6748E-05 mol hydrogen peroxide

5.6748E-05 mol magnesium peroxide = 3.19 mg magnesium peroxide
DNEL (magnesium peroxide) = 3.19 mg/m3
b) composition of reaction mass
DNEL (magnesium peroxide) = 3.19 mg/m3
