Paper Straws May Contain Toxic Chemicals, Study Finds

A recent study has revealed that paper straws may harbor toxic chemicals, raising concerns about their impact on individuals, wildlife, and the ecosystem.

The investigation found that a significant portion of the tested paper and bamboo straws contained poly- and perfluoroalkyl substances (PFAS).

These substances, known for their persistence and potential long-term adverse effects on human health, could potentially pose a threat to both people and the environment.

Concerns raised that paper straws contain toxic chemicals

Paper straws have gained popularity as an “eco-friendly” alternative to the more ubiquitous plastic straws. In countries like the UK, where plastic straws were banned in 2020, paper straws have been adopted by restaurants, cafes, and bars en masse. Their usage is set to rise as other countries and economic blocs such as the European Union seek to limit single-use plastics in a bid to promote more environmentally friendly practices.

Conducted in Europe, a pioneering study examined straws crafted from various materials sourced from retail stores and fast-food establishments. The study uncovered that among the tested brands of paper straws, 18 out of 20 contained PFAS, whereas plastic and glass counterparts exhibited a lower incidence of PFAS presence.

However, the research did not investigate the potential leaching of PFAS from the straws into the beverages they come into contact with.

Of note, the most prevalent PFAS identified was perfluorooctanoic acid (PFOA), a substance that has been globally prohibited since 2020. PFAS is frequently used in products like outdoor apparel and non-stick cookware due to its resistance to water, heat, and stains.

Interestingly, none of the steel straws subjected to testing exhibited any traces of PFAS.

Implications

The levels of PFAS were discovered to be minimal, and given the infrequent use of straws, Belgian researchers concluded that the potential risk to human health is restricted.

Nonetheless, they cautioned that these chemicals could amass within the body over extended periods.

These substances have been linked to various health complications, encompassing reduced vaccine efficacy, diminished birth weight, thyroid disorders, elevated cholesterol levels, harm to the liver, and the development of kidney and testicular cancers.

Dr. Thimo Groffen, from the University of Antwerp, commented that “Straws made from plant-based materials, such as paper and bamboo, are often advertised as being more sustainable and eco-friendly than those made from plastic.”

“However, the presence of PFAS in these straws means that’s not necessarily true,” Dr. Gtroffen added. He advised that consumers “avoid using straws at all”.
