The increase in the complexity of toxicological studies is of utmost importance to an improved environmental risk assessment of emerging chemicals under a changing climate. We are observing the daunting impacts of climate change in both terrestrial and aquatic ecosystems today, aligned with compelling evidence that changes on abiotic factors alter the environmental distribution and toxicity of chemicals. On the other hand, new chemicals arrive on the market every year to meet demand for products and services (from agriculture to health and even leisure activities).
This Special Issue of Toxics invites studies on the combined toxicological effects of abiotic parameters altered due to climate change (e.g., temperature, pH, salinization) and emerging chemicals (e.g., new persistent organic contaminants, personal care products, pharmaceuticals). A variety of topics encompassing the combined effects observed from lower to high levels of biological organization, from the subindividual to the community and ecosystem levels, will be included. We are also looking for studies on the fate and persistence of emerging chemicals in both terrestrial and aquatic systems under changing climate scenarios.

Abstract: Due to global warming, in the northeastern semi-arid coastal regions of Brazil, the regional and global drivers are being responsible for decreasing continental runoff, increasing estuarine water residence time. The increasing water residence time in the estuary, promotes a greater mobilization of mercury bioavailable which allows an acceleration of biogeochemical transformation of mercury, increasing fluxes and/or bioavailability of this toxic trace element. The climate changes could be the most important reason for the intensification of these processes, and is a very possible scenario in a mangrove area that would be further invaded by seawater. favoring the incorporation of fine sediments in the seawater column. An application of dendrochemistry analysis (annular tree rings analysis) was developed to quantify mercury contamination chronologic trends in a low contaminated tropical ecosystem in order to evaluate the consequences of the described increase Hg bioavailability and bioaccumulation in aquatic biota of Tropical semiarid ecosystems (Ceará River Estuary, North-eastern coast of Brazil), as well to a better understanding of the continued fulfillment concerning the global cycle of mercury under a global climate change scenario. To assess the biological significance of mercury concentrations, water column and sediments cores were sampled (during low tide), as also muscle and liver samples from collected juvelile Sphoeroides testudineus (Linnaeus); in parallel were also collected tree ring cores from Rhizophora mangle L (Red mangrove) specimens. Sediment cores and annular tree rings have been used providing data on historical trends of Hg contamination, reconstructing the historical pattern of mercury contamination in the Ceará estuary through registration of mercury concentration on growth rings, and using the assessment in core sediments as a support for comparison of profiles of contamination. The present study aims answer the question “will those chronological patterns of mercury contamination be useful tools evaluating past patterns, understanding present levels and predicting future evolution trend in a Global Climate Change scenario?”
