The map shows the mean annual concentrations of Nitrites (NO2) measured at WISE SoE groundwater monitoring stations during the period 2000 – 2011. All data are annual means aggregated by countries (visible when the map is zoomed to the scale of 1 : 6 000 001 and less detailed) or by WFD groundwater bodies (visible when the map is zoomed to the scale of 1 : 6 000 000 and more detailed).
When travelling to exotic places, choose your souvenirs carefully.
Trade in items such as woodcarvings, red coral or ornaments with fur or feathers, is often regulated and permits are required to bring them home. Check the rules, as there are strict laws governing exports of wildlife and you could risk having your souvenir confiscated.
