Effects of endocrine disruptors in zebrafish (Danio rerio) as revealed with the fish sexual development test
So-called “endocrine disrupting chemicals” (EDCs) are ubiquitous in the environment, especially in aquatic systems close to industrial and agricultural areas. Disturbances of the hormonal balance between estrogens and androgens are one central target of EDCs. Especially during sexual …

The reproductive health effects of along term DDT exposure on malaria vector control workers in Northern Province, South Africa
… of malaria vectors, have been shown to be endocrine disruptors in vitro and in vivo. The study hypothesis was that male vector control workers highly exposed to DDT in the past should demonstrate clinically significant exposure-related anti-androgenic and/or estrogenic effects reflected in …

Occurrence and fate of endocrine disrupting chemicals and other hydrophobic organic compounds in a tropical river in Kenya
… silicone rubber (SR), were used to monitor some endocrine disruptors (EDCs) and hydrophobic organic chemicals (HOCs) in freshwater and sediments of a tropical river in Kenya. PES was applied for the first time for time-integrative sampling of these compound classes and was able to quantify the …

End Use Packaging: A Survey of Customer Perception of Recycling and Environmental Impact of Packaging Materials
… food products. Some of these toxins are known endocrine disruptors, which results in reproductive issues as well as hormone imbalances. Alternatives to traditional food packaging have been addressed with special attention to bioactive, biopolymers, and biodegradable packaging in addition to …

Examining women’s knowledge, health risk perceptions, beliefs and behaviours in relation to toxic chemicals commonly found in personal care and household products: a mixed-methods approach
… parabens, commonly found in shampoos, are endocrine disruptors that increase the risk of hormonal and reproductive disorders among women. Despite safer alternatives, research suggests women are unaware of these risks and options. This research used a mixed-methods approach to examine …

Open source estrogen : from biomolecules to biopolitics... hormones with institutional biopower!
… body and gender sovereignty are deeply at stake, endocrine disruptors termed 'xenoestrogens' pervade our environments due to petrochemical agro-industrial and pharmaceutical forces. These xeno-molecules change the morphology of our bodies and bodies of non-human species, evidencing a malleability …

Efficiency of soil aquifer treatment in the removal of wastewater contaminants and endocrine disruptors. A study on the removal of triclocarban and estrogens and the effect of chemical oxygen demand and hydraulic loading rates on the reduction of organics and nutrients in the unsaturated and saturated zones of the aquifer.
… and also to investigate the removal of the endocrine disruptors triclocarban (TCC), estrone (E1), 17¿-estradiol (E2) and 17¿- ethinylestradiol (EE2). SAT was simulated in the laboratory using a series of soil columns under saturated and unsaturated conditions. Investigation of the removal of …

Investigations into the role of exogenous estrogenic endocrine disrupting chemicals on immune dysregulation in autoimmune disease
Estrogenic endocrine disrupting chemicals (EEDCs) are defined as chemicals that bind to estrogen receptors (ERs) and augment estrogenic functions, either through promoting or blocking estrogen receptor signaling. Recent reports highlight the growing concern surrounding environmental exposure to …
