A recent study conducted in Melbourne found up to 69 different pharmaceuticals have been ingested by wildlife living in various creeks. Over 190 invertebrates sampled were found to have consumed various levels of drugs. While Australia has strict laws in place to minimise pharmaceutical waste ending up in our waterways, somehow a shocking amount has ended up in our creeks. How big is this problem and what effect will this have on our wildlife? Associate Professor Michael Grace, for the school of Chemistry at Monash University, who is a co-author of this research, joined us to discuss this.
