From: Trans-provincial health impacts of atmospheric mercury emissions in China
Composition of attributable per-foetus intelligence quotient (IQ) decrements and fatal heart attacks in a given Chinese region. The composition in a given region results from anthropogenic mercury (Hg) emissions discharged by production activities (a, d), induced by final consumption (b, e), and enabled by primary inputs (c, f) of local and external regions. a–c The results for IQ decrements and d–f the results for fatal heart attacks. Each cell in the grid shows the fraction of the health risk (%) of the column region caused by the production, final consumption, and primary inputs of the row region. The total points of per-foetus IQ decrements that occur in each region are shown at the top of a, and the total deaths from fatal heart attacks that occur in each region are shown at the top of d. The total deaths from fatal heart attacks caused by each region are also shown on the right of d–f. Regions 1 to 9 represent the Northeast, Beijing-Tianjin region, North, Northwest, Central, Central Coast, South Coast, Southwest, and Int’l exports/imports (see Supplementary Fig. 3 for regional definitions). A black-coloured cell in a region reflects the fraction of health risks in the region caused by local activities. In other cells, darker orange cells indicate higher fractions
