3 Scary Plastics to Avoid in Baby Bottles, Water Bottles, More

You're learning to recycle plastics (great!), but now you have probably heard reports of nervous consumers cleaning out their cupboards and closets of containers that experts are warning may not be safe to use. The good news is those recycling codes can help you protect your family, and The Daily Green will tell you how.

Though it's true regulators and the plastics industry are pointing out that the science on the real-world harms is not yet proven, many are saying the stakes are too high, and the alternatives too easy, to ignore. Read on to see which types of water and baby bottles you don't want to give your kids.

Number 3 Plastics
V (Vinyl) or PVC
Found in: Cooking oil bottles, clear food packaging

Harvard-educated Dr. Leo Trasande of the Mt. Sinai School of Medicine advises consumers to avoid number 3 plastics for food and drinks. (If you're unsure, look for the little symbol that should be printed on the container. Some brands have left the symbols off, which is a major problem.)

Why? Number 3 plastics may release toxic breakdown products (including pthalates) into food and drinks.

The risk is highest when containers start wearing out, are put through the dishwasher or when they are heated (including microwaved). PVC manufacturing can release highly toxic dioxins into the environment, and the materials can off-gas toxic plasticizers into your home.

Number 6 Plastics
PS (polystyrene)
Found in: Disposable plates and cups, meat trays, egg cartons, carry-out containers

Number 6 plastics (polystyrene) are made into soft Styrofoam-style cups as well as rigid foams and hard plastic products, so remember to look for those little numbers in the arrows (don't feel bad if you need a magnifying glass). Avoid using them as much as possible.

Why? Number 6 plastics can release potentially toxic breakdown products (including styrene). Get this: particularly when heated! That insulated coffee cup -- the one that 'knows' when to keep your drink warm -- doesn't seem so smart anymore does it?

Number 7 Plastics
Miscellaneous
Found in: Baby bottles, three- and five-gallon water bottles, certain food containers

A wide range of plastic resins that don't fit into the other six categories are lumped into number 7. Some are quite safe, but the ones to worry about are the hard polycarbonate varieties, as found in various drinking containers (like Nalgene bottles) and rigid plastic baby bottles.

Why? Studies have shown polycarbonate can leach bisphenol A, a potential hormone disruptor, into liquids. According to Trasande, no level of bisphenol A exposure is known to be truly safe, and in August a government panel expressed 'some concern' that the ingredient causes neural and behavioral problems in children.

Why not play it safe and swap out those hard plastic baby and water bottles for Number 1, 5 or corn-based plastics, or even shatter-resistant glass?
