“…Thus, Hg concentrations in fish and other components of aquatic food webs may not reflect background Hg loading if environmental conditions are not conducive to microbial Hg methylation. For example, Hg concentrations in fish and aquatic birds have displayed a range of trends in temporal variation since the 1960s, including increases (Drevnick et al, 2015;Vo et al, 2011), decreases (Champoux et al, 2015;Cross et al, 2015), and more variable and complex patterns, such as trend reversals (Gandhi et al, 2014;Monson, 2009), yet there has been approximately a 2-4 fold decrease in net atmospheric deposition since its peak at that time (Beal et al, 2015). Although more recent deposition trends are variable and even increasing in some cases (Weiss-Penzias et al, 2016), the linkage with fish Hg concentrations is thus far equivocal.…”

“…Eggs accumulate different contaminants such as dioxin, PCB, pesticides, and heavy metals like mercury, , predominantly in the yolk. In this study total Ag was also selectively found in yolk and not in albumen.…”

“…Su movilidad en los ecosistemas, el nivel trófico que ocupan, además del uso de hábitats agrícolas, puede resultar en una alta exposición a contaminantes ambientales persistentes, incluyendo los COPs, los bifenilos policlorados (BPC's), los metales y los metaloides (Berny et al, 2002;Fasola, Movalli & Gandini, 1998). Es por ello que las aves acuáticas son utilizadas como bioindicadores de la salud de los ecosistemas y por su consecuente capacidad de bioacumulación (Fasola et al, 1998;Bekhit et al, 2011;Champoux, Rail, Lavoie & Hobson, 2015).…”
