Comments

Nickel emissions represented 162 t in 2006 in mainland France and have fallen since 1990 by 49%. However, important variations have been observed during this period.

There are two main sources of nickel emissions : energy conversion (petroleum refining and electricity production) and manufacturing industry (iron and steel industry, food and drink industry, chemical industry), with respectively 56% and 39% of total emissions in mainland France in 2006. In 1990, the contribution of these sectors was reversed as manufacturing industry represented 55% and energy conversion 38%.

The other sectors have a low contribution to the emissions.

Nickel emissions are mainly due to this metal occurring in trace form in waste heavy fuel oil and also in electric steel plants.

Emissions variations are due to weather conditions and different techniques implemented during this period (less nuclear energy or cold winter requiring greater use of fossil fuels for energy production). For instance, in 1991, emission levels were the highest (360 t). Moreover, since 1999, total emissions reduced in a result of improvements made in iron and steel industry.
