FACT- we are exposed to flame retardants daily.

Q: What types of products use flame retardants?

A: While an ever-evolving list of new products—from hair dryers and small appliances to laptops and flat-screen televisions—is incorporated into our homes, offices and commercial environments, we seldom think about how the products are made. Flame retardants provide consumers with a critical layer of fire protection and are vital to reducing the risks associated with fire.

Today, flame retardants are used predominantly in four major areas:

1 Electronics and Electrical Devices

• Television and other electronic device casings
• Computers and laptops, including monitors, keyboards and portable digital devices

• Washers and dryers
• Vacuum cleaners
• Electronic circuit boards
• Electrical and optical wires and cables
• Small household appliances

2 Building and Construction Materials

• Electrical wires and cables, including those behind walls Insulation materials (e.g., polystyrene and polyurethane insulation foams)
• Paints and coatings which are applied to a variety of building materials, including steel structures, metal sheets, wood, plaster and concrete
• Structural and decorative wood products

They may not be in our food and water but I've only just begin to list the more common products they are used on/in.

There are now even searchable websites that show toys, products and clothing for children that use flame retardants.
