Found pharmaceuticals in every bug sampled - over 190 invertebrates - from six different streams. These included caddisfly larvae, midge larvae, snails and dragonfly larvae. Found pharmaceuticals in spiders living in stream-side vegetation.
Found 69 different drugs in the bugs, including fluoxetine and mianserin (anti-depressants), fluconazole (an anti-fungal), and non-steroidal anti-inflamatories (NSAIDs), often used to treat arthritis.
While we don’t know how these drugs are affecting these invertebrates, we know from other studies pharmaceuticals do affect the lifecycles of other organisms.
We also calculated that animals that eat these aquatic invertebrates, such as platypus, would be receiving half the daily recommended dose of anti-depressants for humans
