Wastewater Treatment Plants: Pharmaceutical fish – SCSU experiments

An experiment that started last week in St. Cloud State University’s Aquatic Toxicology Lab expands upon 2012 studies that determined fish might be affected by pharmaceuticals entering rivers and lakes through wastewater treatment plant effluents. Using larval and adult fathead minnows, it looked at individual and combined exposure to sleep aids, muscle relaxants, painkillers and antidepressants — chemicals previously detected in the environment. Juvenile fish didn’t get as big or escape as fast. Adult females had larger livers. Adult males,,, Read the article here 11:33

They say The Sky isn’t Falling. I disagree! The sky has fallen, and Fishermen are paying for it. Pharmaceuticals in our water

There’s no way around it, the headlines are disturbing.  They describe fish and birds responding with altered behavior and reproductive systems to antidepressants, diabetes medication, and other psychoactive or hormonally active drugs at concentrations found in the environment. About 90% of pharmaceuticals found in the environment arrive there after being excreted. Wastewater treatment plants, meanwhile, are exploring possibilities for boosting their ability to remove pharmaceuticals from sewage. Read the rest here 13:49

Victoria’s Secret: Dumping Raw Sewage Like It’s 1915

When friends of mine recently got norovirus from eating foraged Gulf Island oysters, my first instinct was a strange one. I blamed Victoria. More specifically, I blamed Victoria’s raw sewage, which is pumped out to the Juan de Fuca Strait at a rate of 130 million litres per day. British Columbia’s capital is one of the last major cities north of San Diego to dump all of its untreated waste (including pesticides, street runoff and pharmaceuticals) into the ocean.

Household products, pharmaceuticals make fish unafraid of predators – Waste Water Treatment is Inadequate

A recent US study into the presence of pharmaceuticals in freshwater areas receiving sewage effluent found evidence of the Prozac in fish brains. Showering, brushing your teeth, and going to the toilet can wash dangerous contaminants into waterways that can disrupt fish reproductive systems and make them unafraid of mortal predators, scientists have found. And current sewage treatment processes were not designed to remove the dangerous contaminants. [email protected]  11:12

Pharmaceuticals and personal care products (PPCPs) are found in surface waters worldwide. Wastewater treatment plant effluent is a major source

fishFate and Transport of Three Pharmaceuticals in the Sacramento-San Joaquin Delta – The sharp decline of four pelagic fish species in the Delta in the last decade is just one of several indicators that the ecosystem is severely impaired. Several wastewater treatment plants (WWTPs) discharge into the Delta, directly or through tributaries. Link

Drugged Fish Lose Their Inhibitions, Get the Munchies

Hundreds of different pharmaceuticals are able to slip past conventional wastewater treatment plants and into our waterways, says Jerker Fick, a toxicologist at Umeå University in Sweden and co-author of the new study. “They don’t mysteriously go away after we excrete them.” Scientists have known    for a long time that many pharmaceuticals can persist in rivers and streams, and have behavioral effects on aquatic species in high doses, he says; however, determining whether more dilute concentrations have an effect is harder to establish.
