- Six new Litagion agent profiles and two new themes summarizing CoMeta content related to disinfection by-products and electromagnetic fields
- New blog content: "5G: Will this time be different?"
- Updated Litagion agent and company profiles impacted by newly published peer-reviewed science and newly gathered company information
- Disinfection by-products. Water utilities throughout the developed world employ chlorinated disinfection chemicals to ensure drinking water is free of harmful bacteria, viruses, protozoa, and helminths. Disinfection by-products like the trihalomethanes and haloacetic acids profiled in this theme form when chlorinated disinfection chemicals interact with naturally occurring organic matter. Humans are exposed to these potentially harmful disinfection by-products orally through drinking water and via dermal absorption and inhalation when bathing. The U.S. Environmental Protection Agency has set standards for trihalomethane and haloacetic acid concentrations in drinking water, but those standards are considerably less stringent than corresponding standards in Europe and other developed countries.
- Electromagnetic fields. Humans are exposed to electromagnetic fields (EMF) from a variety of natural and manmade sources including power-frequency fields produced by the generation, transmission, and use of electricity and radiofrequency fields emitted from industrial machinery and wireless networking equipment and devices. This theme brings together four separate EMF related hazard profiles exploring the scientific evidence that non-ionizing radiation at various frequencies is harmful to human health and the liability risk faced by a wide-variety of businesses responsible for exposing us to that radiation.
- Bromodichloromethane. A trihalomethane that forms as the result of treating drinking water with chlorinated disinfection chemicals.
- Bromoform. A trihalomethane that forms as the result of treating drinking water with chlorinated disinfection chemicals.
- Chlorodibromomethane. A trihalomethane that forms as the result of treating drinking water with chlorinated disinfection chemicals.
- Dichloroacetic acid (DCA). A haloacetic acid that forms as the result of treating drinking water with chlorinated disinfection chemicals.
- Radiofrequency fields (5G). Radiofrequency fields emitted from fifth generation wireless networks and devices that operate near the highest frequencies of the RF spectrum.
- Trichloroacetic acid (TCAA). A haloacetic acid that forms as the result of treating drinking water with chlorinated disinfection chemicals.
Updated Litagion agents based on newly published science
All Litagion agent profiles have been updated to reflect the most recently published peer-reviewed science. Notable scientific studies added to CoMeta since the last release include:
- Bisphenol A (BPA). A study with 98 mother-child pairs showed maternal BPA levels during pregnancy are associated with altered brain development in children at ages 2-5.
- Triclosan. The Environmental and Reproductive Health (EARTH) study linked urinary triclosan levels in men to abnormal sperm morphology.
In addition, we highlight the following changes to the components of Litagion agent risk resulting from newly published peer-reviewed science:
|Litagion agent||Risk category change||Overall risk change|
|Perfluorodecanoic acid (PFDA)||Projected science risk changes from Medium (yellow) to Medium-high (orange)||Medium (yellow) to Medium-high (orange)|
Radiofrequency fields (wireless telephones)
|Projected science risk changes from Medium-low (light green) to Medium (yellow)||Medium-low (light green) to Medium (yellow)|
