What Are Microplastics and Are They in Tupperware?

Microplastics are tiny plastic particles smaller than 5mm that pollute our environment and food chain. Here's what you need to know:

• Microplastics are found in Tupperware and other plastic food containers
• They can leach into food, especially when heated or scratched
• Potential health risks include hormone disruption and inflammation
• To reduce exposure:
  • Use glass, stainless steel, or ceramic containers instead of plastic
  • Don't microwave food in plastic containers
  • Replace damaged plastic containers

While more research is needed on long-term health effects, reducing plastic use and choosing safer alternatives can help limit microplastic exposure from food containers.

2. Microplastics explained

2.1 What are microplastics?

Microplastics are tiny plastic bits smaller than 5 millimeters (about the size of a pencil eraser). They're found everywhere, from oceans to mountains. Unlike natural materials, plastics don't fully break down. Instead, they split into smaller and smaller pieces.

2.2 Types of microplastics

There are two main types of microplastics:

2.3 Where do microplastics come from?

Microplastics come from many places:

• Face scrubs and toothpastes
• Clothes shedding fibers when washed
• Making plastic products
• Plastic packaging breaking down
• Car tires and road paint wearing out
• Big plastic trash breaking into smaller pieces

Since the 1950s, we've made about 8 billion tons of plastic. Only about 10% has been recycled. This means a lot of plastic ends up as tiny pieces in our world. We can find microplastics in:

• Household dust
• The air we breathe
• The food we eat

To fix this problem, we need to change how we use and throw away plastic. This includes how we act as buyers, how companies make things, and how we handle trash.

3. Microplastics in food containers

3.1 Are microplastics in Tupperware?

Studies show that microplastics can be in plastic food containers, including Tupperware. These tiny plastic bits (0.1 to 5000 µm) can get into our food and drinks.

Common plastics used in food containers:

3.2 How microplastics get into containers

Microplastics enter food containers in these ways:

1. Making: Small plastic bits can get into the container during production.
2. Breaking down: Heat, light, and use can make plastic containers shed tiny pieces.
3. Use: Regular washing and scratching can release microplastics.
4. Heat: Microwaving can speed up the release of microplastics.

3.3 Research on microplastics in containers

Studies on microplastics in food containers show:

• Opening plastic containers can release microplastics (2020 study).
• Plastic water bottles can shed microplastics into water.
• New plastic food containers have about 12 mg (round) to 38 mg (rectangular) of microplastics.

To lower your contact with microplastics from food containers:

1. Use "food-grade" or "BPA-free" containers
2. Don't microwave food in plastic
3. Check containers for damage and replace if needed
4. Try glass or stainless steel containers
5. Follow the maker's instructions for use and care

4. Health risks of microplastics

4.1 Possible health effects

Microplastics may harm human health. They can contain bad chemicals like:

• Cancer-causing agents
• Hormone disruptors
• Brain-damaging substances
• Chemicals that hurt reproduction

These might cause health problems:

4.2 What studies show

New research tells us:

1. Heart problems: People with microplastics in their arteries were 4.5 times more likely to have heart attacks, strokes, or die within 3 years.

2. How much we take in: We eat about 5 grams of plastic each week - that's like eating a credit card.

3. Where it goes: Scientists have found microplastics in people's lungs, spit, hair, and poop.

4. Carrying other bad stuff: Microplastics can bring harmful things like heavy metals and pesticides into our bodies.

4.3 What we still need to learn

We don't know everything about microplastics yet:

1. Long-term effects: We need to study what happens when people are around microplastics for many years.

2. How the body handles them: We're still figuring out how our bodies deal with microplastics.

3. How much is too much: We don't know exactly how many microplastics it takes to make someone sick.

4. Tiny plastics: We need to learn more about even smaller plastic bits called nanoplastics.

5. Working with other toxins: We're studying if microplastics team up with other pollutants to cause more harm.

Scientists are working hard to answer these questions. For now, it's smart to try to avoid microplastics when we can.

5. Microplastics and Tupperware

5.1 What studies have found

Recent research has looked at microplastics in food containers, including Tupperware. A study found:

These tiny plastic bits came in different shapes: cube, sphere, rod, and odd shapes. The study shows that new plastic containers can release a lot of microplastics.

5.2 How containers are made

The way plastic containers are made affects how many microplastics they release. Things that matter:

• How they're made
• What kind of plastic is used
• What's added to the plastic
• Container shape and thickness

Even containers marked "microwave safe" can release microplastics when heated.

5.3 Comparing different brands

While we don't have info on specific brands, here are tips for safer food storage:

When using plastic:

• Don't put hot, oily, or acidic foods in them
• Replace worn-out containers
• Think about how long you'll store food

6. How to reduce microplastic exposure

6.1 Other container options

To lower your contact with microplastics, try these instead of plastic:

These choices are safer for keeping and heating food, and cut down on microplastic risk.

6.2 Using plastic containers safely

If you need to use plastic containers, follow these tips:

• Don't microwave food in plastic
• Don't put hot or sour foods in plastic
• Throw away old or damaged containers
• Wash plastic containers by hand
• Use cold water to clean plastic things
• Pick containers marked "microwave-safe" or "BPA-free" if you can

Remember, even "microwave-safe" plastic can let out microplastics when heated. It's best to put food in glass or ceramic before heating.

6.3 Choosing better containers

When picking food containers, think about:

7. Fixing the bigger microplastic problem

7.1 Using less plastic

To cut down on microplastics, try these tips:

FAQs

What is microplastic and why is it bad?

Microplastics are tiny plastic bits smaller than 5 mm. They're a problem because:

• Sea animals eat them, which can hurt their stomachs
• They can bring harmful chemicals into the food chain
• People might eat or drink them in food and water

We're still learning about how microplastics might affect our health over time.

Should I throw away my old Tupperware?

There's no set time to replace plastic containers, but it's good to get rid of them when they look worn out. Look for:

• Chips or cracks
• Stains or smells that won't go away
• Changes in color

To lower your contact with possible microplastics and bad chemicals, try these instead of plastic:

These choices are safer for storing food and can help cut down on plastic use.
