Phthalate esters are ubiquitous in today’s environment. Both terrestrial and aquatic organisms are subject to a low level but constant exposure to this class of chemicals. Until very recently, it was not thought likely that any phthalates would display endocrine activity, and hence very little, if any, research focused on this possibility. When reproductive effects were observed, they were not interpreted...
Although the words ‘endocrine disruption’ were introduced only relatively recently, some of what are now considered the clearest and best documented examples of endocrine disruption in aquatic organisms were first described 20 or more years ago. These include imposex in molluscs induced by tributyl tin (TBT) and masculinisation of some species of fish living downstream of where pulp mill effluent...
Despite the fact that concern was raised a few decades ago about the (probable) presence of human pharmaceuticals in the aquatic environment (e.g. Aherne et al.) , the issue received little attention until two discoveries coincided. One was the finding by several analytical chemists, Thomas Ternes in particular, that many different human pharmaceuticals were present in effluents of sewage treatment...
Background Treated effluents from wastewater treatment works can comprise a large proportion of the flow of rivers in the developed world. Exposure to these effluents, or the steroidal estrogens they contain, feminizes wild male fish and can reduce their reproductive fitness. Long-term experimental exposures have resulted in skewed sex ratios, reproductive failures in breeding colonies, and population...
Factors affecting egg quality are determined by the intrinsic properties of the egg itself and the environment in which the egg is fertilized and subsequently incubated. Egg quality in fish is very variable. Some of the factors affecting egg quality in fish are known, but many (probably most) are unknown. Components that do affect egg quality include the endocrine status of the female during the growth...
