What are they?

Pharmaceuticals and personal care products (PPCPs) include all prescription, over-the-counter, and veterinary medications made for humans and animals, such as antibiotics, supplements, growth hormones, and birth control hormones (pharmaceuticals), as well as cosmetics, soaps, lotions, and hair and dental care products (personal care products). The only PPCP detected in PollutionTracker samples to date is triclocarban, an antibacterial agent commonly used in soaps.

How do they get into the ocean?

PPCPs largely enter the marine environment via wastewaters from areas of urbanization and animal production. Pharmaceuticals are also used at aquaculture facilities to prevent and treat outbreaks of disease and sea lice.1 While some PPCPs degrade quickly, they are considered pseudo-persistent in the environment due to continual inputs.1 Others, such as the antimicrobial agents triclosan and triclocarban persist in the environment and are known to accumulate in aquatic organisms, including algae, worms, fish, and dolphins.2

Are they a problem?

PPCPs can have a variety of toxic effects in biota, and the potential effects of many PPCPs are currently unknown.

FACT: The effects of PPCPs on non-target organisms in the environment may be so subtle that they are undetectable, but these effects are potentially cumulative and may be significant over time.3

Pharmaceuticals of special concern in the environment are those used for chemotherapy (antineoplastics), birth control and growth hormones (endocrine disruptors), and antibiotics.1 Antimicrobial agents are considered particularly problematic components of personal care products.1 Adverse effects on non-target organisms following laboratory exposure to pharmaceuticals include disruption of hormones and enzymes (molecules that speed up chemical reactions in the body) in fish, toxicity and disruption of community structure in algae, and changes in sex-ratios in amphipod populations.1 The antimicrobial agents triclosan and triclocarban are widely accepted as toxic to aquatic organisms and have been found to be more effective in inhibiting or killing algae, crustaceans, and fish than in killing their target (microbes).2 However, their potential effects on human health are less well understood, and Health Canada considers triclosan and triclocarban safe for humans at current levels of exposure.4,5

What is being done?

There are no environmental quality guidelines for PPCPs in Canada. Environment and Climate Change Canada is currently undertaking a risk assessment process for triclosan, with the objective of reducing the quantity of triclosan released to the aquatic environment.5 In 2016, the United States Food and Drug Administration banned the use of triclosan, triclocarban, and 17 other chemicals in over-the-counter personal care products. The 2016 Florence Statement on triclosan and triclocarban has been signed by more than 200 international scientists and medical professionals, with the aim of sharing current scientific research motivating broader consideration of the long-term impacts of antimicrobial use.6

What can you do?

As individuals and organizations, we can:

  • Learn more about PPCPs and other contaminants of concern using the resource links below.
  • Recycle and dispose of waste responsibly and according to local guidelines. For example, pharmaceuticals that have expired or are no longer being used should be taken to a pharmacy for disposal.
  • Avoid using products that contain PPCPs known or suspected to cause toxicity in either humans or the environment (e.g., triclosan in soaps and toothpaste).
