Sip safely: Protecting yourself from lead in cups

Tumblers and reusable water bottles are all the rage in Singapore. From gigantic cups to cute bottles that fit in the smallest of pockets, you’ll find these vessels lining the office pantry and poking out of everyday backpacks.

Packing tumblers or reusable bottles as your everyday travel companion makes sense. It’s an eco-friendly alternative to buying new bottled water to quench your thirst several times a day, minimising landfill plastic waste in the process. Providing you wash your cup diligently, using a tumbler could also be a cleaner and healthier option as you can be sure that the drinking water is uncontaminated. But is it truly that simple?

The risk of lead exposure is an under-explored downside of using a metal-sealed tumbler or water bottle. It’s a risk that many people may not be aware of: Is your water bottle safe, and what do you need to know to minimise the risk of lead exposure? Check out the infographic below for more answers.

Don’t bottle it up! Get the facts here.

Why do some bottles contain lead?

Discover how and why manufacturers use lead to produce reusable drinking bottles1.

Tip:
Wonder why lead is the industry-standard sealing material for drinking cups and bottles? From a manufacturing perspective, lead has one distinct advantage: cost. Working with alternatives like lead-free silica or glass are often costlier and more complex, requiring rounds of performance testing or investing in new ovens2. For this reason, many manufacturers simply fall back on the tried-and-tested option despite potential health risks.

Check the website of the company that manufactures your water bottle for more information on their manufacturing process and the type of sealant they use.

Reusable water bottles are vacuum-sealed so the liquid inside can stay warm or cold.

These vessels have two layers with a space in between, sealed together with lead at the bottom.

The sealant is coated with stainless steel to prevent direct contact with the liquid or your skin.

The lead inside can be exposed if the bottle is damaged or if the coating is corroded.

Some companies use alternative materials as sealant to keep their bottle lead-free.
