Triclosan: Currently under review by Health Canada, it's found in antibacterial soaps and body washes, toothpaste and some cosmetic products and is thought to contribute to antibiotic resistance. It's also toxic to aquatic bacteria and various types of algae and can affect the structure of algal communities.
Phthalates: They're chemicals used to add fragrance to products that include body lotions and nail polishes, and to make plastics more flexible. There are concerns that they interfere with the body's endocrine system. There have also been studies suggesting prenatal phthalate exposure could be associated with less male-typical play behaviour in boys.
Microbeads: Tiny pebbles of plastic commonly used in facial and body scrubs, they're so minuscule that water-treatment systems fail to capture them, so they end up in lakes and rivers — and in the gullets of fish.
