Organochlorine contamination in bird's eggs from the Danube Delta

TL;DR: In this paper, a review of traditional and modern Chinese rice agriculture is presented, including detailing historical changes and their implications for wild birds in rice fields in China, where traditional practices, with one crop each year and long periods of fallow flooding, provide greater benefit to biodiversity and species such as the Crested Ibis (Nipponia nippon).

TL;DR: Waterbirds are particularly subject to accumulation of persistent organic pollutants (POPs) that have been shown to constitute a major hazard for this group of birds, and low level exposure to these contaminants may constitute one of the many stressors that in combination could adversely affect bird populations.

TL;DR: The values found were generally lower than those reported for the eggs of large herons from North America or the Mediterranean basin, and are about the same order of magnitude that those of other medium-sized egrets from other parts of the world.

TL;DR: This study shows that embryonic exposure to estrogenic compounds can induce permanent effects in male birds, and o,p′-DDT also induced alterations not seen in the EE2-treated birds.

TL;DR: The most toxic halogenated aromatic is 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) and based on in vivo and in vitro studies the relative toxicities have been determined relative to TCDD (i.e., toxic equivalents).

TL;DR: The most toxic halogenated aromatic is 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) as discussed by the authors.

TL;DR: The epidemiological evidence from this study strongly suggested that contaminants were a causal factor in Forster's tern reproductive success on organochlorine contaminated Green Bay compared to a relatively uncontaminated inland location at Lake Poygan.

TL;DR: In this paper, the effects and problems of toxic contaminants entering into and moving through the Great Lakes, describing the physical and chemical processes of lake pollution, were discussed, with a view to control these processes, including methodologies for environmental monitoring.
