The trends are calculated using a median of pairwise slopes algorithm. Black dots represent high confidence in the sign of the long-term trend in the box (if the
5th to 95th percentile slopes are of the same sign). Boxes which have a thick outline contain at least three stations. Area averaged annual time series of percentage changes and trend lines are shown below each map for one area in northern Europe (blue line, 5.6 to 16.9 °E and 56.2 to 66.2 °N) and one in south‑western Europe (red line, 350.6 to 1.9 °E and 36.2 to 43.7 °N).
Anything you pour down your drain, sink or toilet can eventually end up in our rivers or sea! Never dispose of liquids such as oils, grease, or hazardous liquids – like paint thinners or unused paint – by pouring them down the drain. Instead, collect them in one box and dispose with the rest of your waste. Keep them all in their individual packaging, to avoid possible chemical reactions. This will also make it easier for them to be identified during waste collection. If applicable, take them to your community collection point.
