Spatio-temporal distributions

This paper aims to evaluate the spatiotemporal distribution of six heavy metals (arsenic - As, cadmium - Cd, mercury - Hg, lead - Pb, zinc - Zn, and iron - Fe) in water and sediment environment and assess the pollution status of the heavy metals based on individual metals and overall metal contamination levels as well as a multiple metals index for the monitoring and sustainable management of estuarine environment of Ba Ria-Vung Tau Province.

Rocky outcrops in the intertidal zones of estuaries often contain a highly diverse microbenthic community which includes the hermit crab, Clibanarius symmetricus, an abundant species on the equatorial Amazon coast. However, the ecology of this anomuran is poorly understood. Given this, the present study investigated the spatiotemporal distribution and structure of the C. symmetricus populations that inhabit the rocky outcrops of the Marapanim estuary in northern Brazil.

The rhizosphere is the region close to a plant’s roots, where various interactions occur. Recent evidence indicates that plants influence rhizosphere microbial communities by secreting various metabolites and, in turn, the microbes influence the growth and health of the plants. Despite the importance of plantderived metabolites in the rhizosphere, relatively little is known about their spatiotemporal distribution and dynamics.

In Austria, particulate matter is measured in agreement with national legislation as Total Suspended Particulate (TSP) at more than 110 sites, whereas PM10 measurements are not yet available. It was assumed that ambient air TSP levels can be attributed to the contribution of local sources and regional background concentrations. Both of them were modelled separately. The starting point for the modelling of local contributions was the availability of a spatially disaggregated emission inventory for nitrogen oxides (NOx).
