Brazilian mangroves cover about 11,100 km2 and provide a wide range of ecosystem
services. Despite their importance, they are one of the most impacted ecosystems because …

Among potential toxic elements (PTEs), arsenic (As) and mercury (Hg) are well known for
the toxicity of their different chemical species and diffusion in the environment via several …

We sampled abiotic and food web components in an impacted estuarine system to assess
the transfer and fate of rare earth elements (REE). REE (based on dry weight) were …

This work reports the determination of mercury in fish samples purchased at a public market
in Belem City, Brazil. The mercury quantification was performed using the DMA method …

Many hypotheses have been raised about the controls of the distribution and fractionation of
the rare earth elements (REE) in coastal ecosystems. Here, REE were measured in …

This work reports assessing risks to human health resulting from mercury levels in sardines
(Sardinella brasiliensis), which have been highly consumed by the low-income population …

The present study evaluated the occurrence of 24 Polycyclic Aromatic Hydrocarbons (PAHs)
in sediments and shellfish (Anomalocardia flexuosa, Crassostrea rhizophorae, and Mytella …

The recent substantial expansion of human activities in northeast (NE) China has resulted in
increased emission of environmental pollutants. Longer-term records of such environmental …

This paper describes a novel method based on an ultrasound-assisted extraction microscale
device (UAE-MSD) for the rapid and simultaneous determination of polycyclic aromatic …

Spatial and temporal variations of mercury (Hg) concentrations, enrichment, and potential
ecological risks were studied in a suite of lead-210 (210 Pb) dated sediment cores from 13 …
