Exposure to Air Pollution 30 Years Ago Associated with Increased Risk of Death
Exposure to air pollution more than 30 years ago may still affect an individual's mortality risk today, according to new research from Imperial College London.
Low-Cost, Portable NQR Spectroscopy
A researcher at Case Western Reserve University is developing a low-cost, portable prototype designed to detect tainted medicines and food supplements that otherwise can make their way to consumers. The technology can authenticate good medicines and supplements.
Ocean Acidification Makes Coralline Algae Less Robust
Ocean acidification (the ongoing decrease in the pH of the Earth’s oceans, caused by the uptake of CO2 from the atmosphere), is affecting the formation of the skeleton of coralline algae which play an important part in marine biodiversity, new research from the University of Bristol has found.
Battery Component Found to Harm Key Soil Microorganism
The material at the heart of the lithium ion batteries that power electric vehicles, laptop computers and smartphones has been shown to impair a key soil bacterium, according to new research.
Living a “Mixotrophic” Lifestyle
Some tiny plankton may have big effect on ocean’s carbon storage.

Scripps researchers' analysis shows highly variable pollutant concentrations in fish meat.
Global Nitrogen Footprint Mapped
Four countries cause almost half the world’s emissions, with developing countries tending to suffer local pollution caused by foreign demand.
Environmental Toxin May Increase Risk of Alzheimer's
First time scientists have observed brain tangles in an animal model through exposure to environmental toxin.
Global Ocean Warming has Doubled in Recent Decades
Lawrence Livermore scientists, working with National Oceanic and Atmospheric Administration and university colleagues, have found that half of the global ocean heat content increase since 1865 has occurred over the past two decades.

Approaches to Screening for Risk from Pharmaceuticals in Drinking Water and Prioritization for Further Evaluation
Bookmark and Share

EPA

The presence of pharmaceuticals in drinking water is not a new issue. In the 1970’s, several researchers reported the presence of clofibric acid, a breakdown product of several blood lipid regulators, and salicylic acid, a breakdown product of aspirin, in waste water. However, as analytical techniques grew more sensitive over the years, many more pharmaceuticals have been detected in ambient water, wastewater, and drinking water.

During 1999-2000, the U.S. Geological Survey carried out the first national survey of the occurrence of pharmaceuticals, hormones, and other chemicals in 139 streams from 30 states. A total of 95 contaminants were targeted, with 80 percent of the streams testing positive for one or more contaminants.

Pharmaceuticals enter water through: flushing unused medications down the toilet or sink; excreting unabsorbed medications into the sewage system; farm animals excreting veterinary drugs into fields where they run off into lakes and streams; and commercial improper disposal methods. Conventional water and wastewater treatment methods allow many pharmaceuticals to pass through unchanged, entering the environment and ultimately the drinking water.

One problem with assessing risk of pharmaceuticals in drinking water is the very large number of pharmaceuticals in use today. Information on the occurrence of pharmaceuticals in drinking water is available only for a limited number of compounds. In addition, many pharmaceuticals are biologically degraded to active metabolites that have not been evaluated.

In addition, many pharmaceuticals are biologically degraded to active metabolites that have not been evaluated.

A number of different approaches have been suggested and published in the peer reviewed literature for screening and prioritizing the hazard posed by low concentrations of pharmaceuticals in drinking water. This white paper summarizes and evaluates a number of risk assessment approaches (including EPA’s current approach), that EPA is aware of, that have been described in the literature. This paper is not a comprehensive compilation of all published approaches. In addition, this paper describes EPA’s current activities and research strategy for pharmaceuticals in water.
