Table S1 shows the annual average change in ozone, spatially-weighted over the receptor region, due to 10% anthropogenic NOx emission reductions in each source region. Table S2 shows these results for experiments where NOx, NMVOCs and CO are reduced simultaneously from three source regions. Comparing with the three-month population-weighted indicators in Tables 2 and 4 of the main paper, the st...

SPreAD-GIS is a tool for modeling spatial patterns of anthropogenic noise propagation in natural ecosystems. SPreAD-GIS incorporates commonly available datasets on land cover, topography, and weather conditions to calculate noise propagation patterns and excess noise above ambient conditions for one-third octave frequency bands around one or multiple sound sources. User-specified noise source c...

Surface water samples of baseflow were collected from 20 headwater sub-watersheds which were classified into three types of watersheds (natural, urban and agricultural) in the flood, dry and transition seasons during three consecutive years (2010-2012) within a coastal watershed of Southeast China. Integrating spatial statistics with multivariate statistical techniques, river water quality vari...

Background and Purpose: In the environment, heavy metals in high concentration are toxic to most organisms. Human activities have continuously increased the concentration of these metals in the environment such as soils. In the present study, soil samples collected from Ahvaz IV industrial estate in Khuzestan Province. Materials and Methods: The soil samples were taken from 9 ...

[1] We develop a mechanistic representation of land-atmosphere cycling in a global 3-D ocean-atmosphere model of mercury (GEOS-Chem). The resulting land-oceanatmosphere model is used to construct preindustrial and present biogeochemical cycles of mercury, to examine the legacy of past anthropogenic emissions, to map anthropogenic enrichment factors for deposition, and to attribute mercury depos...
