TL;DR: It is estimated that brackish water discharges through the shoreline are important contributors to the DIN, SiO2, Fe, and Zn budgets of the nearshore waters of Majorca.
Abstract: Submarine groundwater discharge (SGD) and derived nutrient (NO2–, NO3–, NH4+, PO43–, and SiO2) and trace element (Cd, Co, Cu, Fe, Mo, Ni, Pb, V and Zn) loadings to the coastal sea were systematically assessed along the coast of Majorca Island, Spain, in a general survey around the island and in three representative coves during 2010. We estimated that brackish water discharges through the shoreline are important contributors to the DIN, SiO2, Fe, and Zn budgets of the nearshore waters. Furthermore, our results showed that SGD-derived elements are conditioned by the hydrogeological formations of the aquifer and discharge type. Thus, while rapid discharges through karstic conduits are enriched in SiO2 and Zn, the large detrital aquifers of the island typically present enhanced concentrations of Fe. The estimated total annual inputs of chemicals constituents discharged by SGD to the coastal waters were as follows: DIN: 610 × 103 kg yr–1, SiO2: 1400 × 103 kg yr–1, Fe: 3.2 × 103 kg yr–1, and Zn: 2.0 × 103 kg y...

TL;DR: Investigations of the contents of Cu, Zn, Cd, Pb, Hg, and As in fish found a positive correlation between fish length and Hg concentration, which might indicate that advantageous changes are occurring in the concentrations of heavy metals in the southern Baltic environment.

TL;DR: At around 15% of the 96 h LC50, different metals exert different effects on the social behaviour of fish, suggesting potential implications for social structure and population stability.

TL;DR: Wang et al. as discussed by the authors evaluated trace metals in the soil and plant samples collected from lead-zinc smelting areas in Huixian of Northwest China, indicating a certain extent of spreading of trace metal pollution.

TL;DR: The degree of metal bio-accumulation in leaves and pneumatophores suggest contrasting hydrological behaviors and near-surface geochemical conditions favoring differential metal uptake by mangrove plants in the two sites.
