  2. Polystyrene - Wikipedia

    en.wikipedia.org/wiki/Polystyrene

    Whether polystyrene can be microwaved with food is controversial. Some containers may be safely used in a microwave, but only if labeled as such. [114] Some sources suggest that foods containing carotene (vitamin A) or cooking oils must be avoided. [115] Because of the pervasive use of polystyrene, these serious health related issues remain ...

    en.wikipedia.org/wiki/Phase-out_of_polystyrene_foam

    Expanded polystyrene, often termed Styrofoam, is a contributor of microplastics from both land and maritime activities. Polystyrene is not biodegradeable but is susceptible to photo-oxidation, and degrades slowly in the ocean as microplastic marine debris. Animals do not recognize polystyrene foam as an artificial material, may mistake it for ...

    en.wikipedia.org/wiki/Styrofoam

    Styrofoam is a genericized trademarked brand of closed-cell extruded polystyrene foam (XPS), manufactured to provide continuous building insulation board used in walls, roofs, and foundations as thermal insulation and as a water barrier.

  6. Microwave - Wikipedia

    en.wikipedia.org/wiki/Microwave

    A microwave oven passes microwave radiation at a frequency near 2.45 GHz (12 cm) through food, causing dielectric heating primarily by absorption of the energy in water. Microwave ovens became common kitchen appliances in Western countries in the late 1970s, following the development of less expensive cavity magnetrons. Water in the liquid ...

  8. Electromagnetic radiation and health - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_radiation...

    The mechanism is the same as that used in a microwave oven. [6] The heating effect varies with the power and the frequency of the electromagnetic energy, as well as the inverse square of distance to the source. The eyes and testes are particularly susceptible to radio frequency heating due to the paucity of blood flow in these areas that could ...

  9. Expanded polystyrene concrete - Wikipedia

    en.wikipedia.org/wiki/Expanded_polystyrene_concrete

    It is created by using small lightweight EPS balls (sometimes called Styrofoam) as an aggregate instead of the crushed stone that is used in regular concrete. [3] It is not as strong as stone-based concrete mixes, but has other advantages such as increased thermal and sound insulation properties, easy shaping and ability to be formed by hand ...
