Review of emerging contaminants in aquatic biota from Latin America: 2002–2016

Abstract

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.

Biodiversidade: Iniciativas Populares Do Movimento Estudantil Nacional Da Biologia

“…Diversos outros fatores antrópicos promovem impactos nos indicadores de biodiversidade, como o uso de agrotóxicos pela agricultura e a poluição dos ecossistemas por contaminantes industriais, urbanos e demais contaminantes emergentes, apesar de que a magnitude e abrangência de seus impactos para a biodiversidade sejam amplos e pouco compreendidos (SLUIJS et al, 2015;LLORCA et al 2017).…”

Políticas Públicas De Saneamento Básico: Reflexos Sobre a Balneabilidade Das Praias Do Extremo Sul De Santa Catarina

“…A falta de um sistema eficiente leva a uma grande deposição de efluentes a jusante da fonte poluidora em corpos hídricos que irão posteriormente desembocar nos mares (LEMOS; FERREIRA-NETO; DIAS, 2010). O crescente despejo de esgotos e águas residuais não tradadas nos corpos hídricos, juntamente com o escoamento industrial e agrícola, tem resultado na degradação da qualidade da água no mundo inteiro (FRIES et al, 2016;LLORCA et al, 2017). A amplitude desses impactos ambientais é de difícil mensuração, mas de grande gravidade, uma vez que as regiões estuarinas possuem grande diversidade, servem de fonte de renda e lazer e acabam sofrendo com o excesso de dejetos e sedimentos contaminados (SCHNACK et al, 2018).…”

Emerging Contaminants in Trans-American Waters

“…The American continent was chosen because it includes countries with different Human Development Indices (HDIs) (PNUD, 2016;; while the United States and Canada enjoy high HDIs, and have robust systems for the control of water quality and sanitation as well as important infrastructure for research in analytical chemistry and engineering, among others, most of Latin America and the Caribbean lack policies for the care of water and/or wastewater treatment facilities, and in some cases, even for drinking water. In fact, it is considered one of the geographic areas most susceptible to higher levels of pollutants in aquatic biota (Llorca et al, 2016).…”
