Sewers hold the secrets of the city<\/a><\/h2>\n

\"toilet12.jpg\"<\/p>\n

Your toilet knows what you did last summer.<\/p>\n

Apparently, one way to estimate drug-use rates in a city is to tap into its sewers<\/a>. The city of Oslo did this with what’s called a Passive Sampler\u2014filters that continuously collect samples of chemicals in the environment. After several weeks, old filters are replaced with new ones and the collection membranes are taken to a lab and analyzed with mass spectrometry. The same system has been used to look for pollution near oil derricks. But it can be configured to check for other substances, too.<\/p>\n

For instance, in Oslo, levels of the drug ecstasy spiked in the city’s sewer water, increasing 10 fold, during the two weeks when Norwegian teenagers celebrate high school graduation<\/a>.<\/p>\n
