“…The dolphins were collected with appropriate permission from Brazilian Environmental Agencies (Brazilian Institute of the Environment/Ministry of the Environment, permission number 11495). Male dolphins were analyzed to eliminate bias resulting from the transfer of female contaminant loads to their progeny 21 . Rio de Janeiro State University, Aquatic Mammals and Bioindicator Laboratory, staff performed the necropsies and collected tissues using a sterilized stainless steel scalpel.…”

To catalog the diversity and abundance of halogenated organic compounds (HOCs) accumulating in high trophic marine species from the southwestern Atlantic Ocean, tissue from bottlenose dolphins (Tursiops truncatus) stranded or incidentally captured along the coast of Rio de Janeiro, Brazil, were analyzed by a non-targeted approach based on GC×GC/TOF-MS. A total of 158 individual HOCs from 32 different structural classes were detected in the blubber of 4 adult male T. truncatus. Nearly 90 percent of the detected compounds are not routinely monitored in the environment. DDT-related and mirex/dechlorane-related compounds were the most abundant classes of anthropogenic origin. Methoxy-brominated diphenyl ethers and chlorinated methyl- and dimethyl bipyrroles (MBPs and DMBPs) were the most abundant natural products. Reported for the first time in southwestern Atlantic cetaceans and in contrast to North American marine mammals, chlorinated MBPs and DMBPs were more diverse and abundant than their brominated and/or mixed halogenated counterparts. HOC profiles in coastal T. tursiops from Brazil and California revealed a distinct difference, with a higher abundance of mirex/dechloranes and chlorinated bipyrroles in the Brazilian dolphins. Thirty-six percent of the detected HOCs had an unknown structure. These results suggest broad geographical differences in the patterns of bioaccumulative chemicals found in the marine environment, and indicate the need to develop more complete catalogs of HOCs from various marine environments.

“…These findings are of concern because it is known that UV filters such as benzophenone 3 (BP3), benzophenone 4 (BP4) and ethylhexylmethoxycinamate (EHMC) are able to alter the transcription profile in fish, with the possibility of altering genes related with the production of sexual hormones (Blüthgen et al, 2012, Zucchi et al, 2011a. Moreover, when UV filters were investigated in tissues of paired mother-fetus franciscana (Pontoporia blainvillei) and Guiana (Sotalia guianensis) dolphins from Brazilian coastal waters, the comparison of UVF concentrations in maternal tissues (blubber 105 ± 155, and muscle 2,175 ± 3,720 ng/g lw) and fetal tissues (blubber 125 ± 115, and muscle 2,490 ± 4,120 ng/g lw) showed up to 10 times higher load in fetuses than in their mothers (Alonso et al, 2015).…”

This work presents the occurrence and fate of selected personal care products (PCPs) in the urban river-groundwater interface. To this end, urban river and groundwater samples were collected in Sant Adrià del Besòs (NE of Spain) and a total of 16 PCPs were analyzed including benzophenone derivatives, camphor derivatives, p-aminobenzoic acid derivatives, triazoles and parabens in three different campaigns (from May 2010 to July 2014). These compounds reach the aquifer through the recharge of Besòs River that receives large amounts of effluents from waste water treatment plants.Results shown that most of compounds were not or barely detected (maximum concentrations around 200 ng/L) in groundwater samples during the different sampling campaigns. Only two triazoles, namely benzotriazole (BZT) and methyl benzotriazol (MeBZT) were found at high concentrations in groundwater samples (maximum concentration around 2000 ng/L). The fate of PCPs in the aquifer was assessed using mixing analysis considering the seasonal variability of the Besòs River. Overall, measured groundwater concentrations were significantly much lower than those estimated by the mixing of the river water. This observation suggested that most of the PCPs are naturally removed when river water infiltrates the aquifer. However, some compounds were more persistent in the aquifer. These compounds were in descending order: the triazoles BZT and MeBZT followed by the camphor derivative 4MBC and the paraben MePB. The measured concentrations allowed us to assess the environmental risk posed by the selected UV-filters and parabens in the river and groundwater samples. Hazard Quotients (HQs) for different aquatic species were calculated in order to characterise the ecotoxicity potential of the studied compounds in the river-groundwater interface.HQ values were always below 1 indicating that at the concentrations observed in the surface or aquifer water of Besòs River these compounds pose no risk to the selected aquatic organisms.

“…That study also provided evidence that maternal transfer to the fetus might occur through the placenta and likely through breast milk . This hypothesis was proven shortly afterward by the same authors, examining 38 samples including bubbler, muscle, and milk from 12 mother–fetus dolphin pairs from the Franciscana and Guiana species . Octocrylene and 3 other organic UV filters (EHMC, 4‐methylbenzylidene camphor, and octyl dimethyl‐ p ‐aminobenzoic acid) were measured in 36 of the 38 samples and in all mother–fetus pairs; accumulation was predominant in muscle samples .…”

“…However, despite the low environmental persistence of pharmaceuticals and pyrethroid pesticides, the presence of their metabolites in biota should also be assessed: pesticides and pharmaceuticals are designed to be bioactive, and some of their metabolites and transformation products can have equal or higher potency than the parent chemicals . In fact, some recent studies have reported the presence of metabolites of these compounds in aquatic biota, mammals , and even human samples .…”

Although it is known that emerging contaminants are widespread all over the globe, there is a gap of information about their distribution in some geographical areas, such as Latin America. The present bibliographic work reviews the available literature about the presence of organic emerging contaminants in Latin American freshwater and marine biota between 2002 and 2016 and includes 23 works from Argentina, Brazil, Chile, Colombia, Mexico, and Nicaragua. In particular, the present review provides an overview of the occurrence of continuously present contaminants such as pharmaceuticals, personal care products, and pyrethroid insecticides, as well as the new groups of persistent organic pollutants, the halogenated flame retardants and the perfluoroalkyl substances. A wide overview is provided, considering not only occurrence data but also effects and potential transfer through the food chain. Environ Toxicol Chem 2017;36:1716-1727. © 2016 SETAC.
