Plastics are everywhere and in most cases are very affordable and convenient. But, increasingly scientists are finding that a hidden cost may be our health. Some common plastics release harmful chemicals into our air, foods, and drinks. Maybe you can’t see or taste it, but if you’re serving your dinner on plastic, you’re likely eating a little plastic for dinner.
Beyond the immediate health risks, our increasing use of plastics is causing an enormous amount of enduring pollution. Every bit of plastic that has ever been created still exists (except for the little bit that has been incinerated, which releases toxic chemicals). In the ocean, plastic waste is accumulating in giant gyres of debris where, among other thing, fish are ingesting toxic plastic bits at a rate which will soon make them unsafe to eat.
Plastic is generally toxic to produce, toxic to use, and toxic to dispose of. Luckily, we can all make safer choices.
The best thing to do is to reduce your use of plastic. Look for natural alternatives like textiles, solid wood, bamboo, glass, stainless steel, etc. Also, look for items with less (or no) plastic packaging. If you do buy plastic, opt for products you can recycle or re-purpose (e.g. a yogurt tub can be re-used to store crayons). And, get to know your plastics – starting with this guide:
The most common plastics have a resin code in a chasing arrow symbol (often found on the bottom of the product).
PET (Polyethylene Terephthalate): AVOID
Common Uses: Soda Bottles, Water Bottles, Cooking Oil Bottles Concerns: Can leach antimony and phthalates.
HDPE (High Density Polyethylene): SAFER
Common Uses: Milk Jugs, Plastic Bags, Yogurt Cups.
PVC (Polyvinyl Chloride, aka Vinyl): AVOID
Common Uses: Condiment Bottles, Cling Wrap, Teething Rings, Toys, Shower Curtains Concerns: Can leach lead and phthalates among other things. Can also off-gas toxic chemicals.
LDPE (Low Density Polyethylene): SAFER
Common Uses: Produce Bags, Food Storage Containers.
PP (Polypropylene): SAFER
Common Uses: Bottle Caps, Storage Containers, Dishware.
PS (Polystyrene, aka Styrofoam): AVOID
Common Uses: Meat Trays, Foam Food Containers & Cups Concerns: Can leach carcinogenic styrene and estrogenic alkylphenols.
Other: This is a catch-all category which includes:
PC (Polycarbonate): AVOID - can leach Bisphenol-A (BPA). It also includes ABS (Acrylonitrile Butadiene Styrene), SAN (Styrene Acrylonitrile), Acrylic, and Polyamide. These plastics can be a safer option because they are typically very durable and resistant to high heat resulting in less leaching. Their drawbacks are that they are not typically recyclable and some need additional safety research. New plant-based, biodegradable plastics like PLA (Polylactic Acid) also fall into the #7 category.
