Mobile phones must not release (too much) nickel

The legislation has come into effect, and it is now illegal to sell mobile phones that do not comply with the new regulations.
Head-sets are also covered by the directive.

A fungicide, dimethyl fumarate, has led to a range of allergic reactions across countries in Europe. The allergies were caused by exposure to dimethyl fumarate in consumer products such as furniture, shoes and riding helmets produced in China.

In Denmark, the first case of an allergic reaction to dimethyl fumarate was in Ålborg and was due to use of the fungicide in an armchair.
