The graph shows the change in emissions of acidifying pollutants (sulphur dioxide SO2, nitrogen oxides NOx and ammonia NH3) each weighted by an acid equivalency factor prior to aggregation to represent their respective acidification potentials. The acid equivalency factors are given by: w(SO2) = 2/64 acid eq/g = 31.25 acid eq/kg, w(NOx) = 1/46 acid eq/g = 21.74 acid eq/kg and w(NH3) = 1/17 acid eq/g = 58.82 acid eq/kg.

Think twice before buying more toys for your children.
Many of them are used only very shortly and then thrown away. Go for high-quality, long-lasting toys that can be used by several generations of children. Selling old toys on a flea market can give your toys a second life and can be much fun for you and the kids.
