Melamine dishware is popular because it is affordable and shatter resistant, making it specifically attractive for serving children. The melamine compound, which is partly composed of formaldehyde, is posited to pose health risks such as bladder and kidney problems. Chia-Fang Wu, from Kaohsiung Medical University (Taiwan), and colleagues found that six men and six women, ages 20 to 27 years, who consumed hot noodle soup served in melamine bowls, showed significantly more melamine excreted in their urine, as compared to when they ate the food from ceramic bowls. Total 12-hour melamine excretion was 8.35 mcg) after eating from the melamine bowls, compared with 1.31 mcg when ceramic bowls were used, the researchers noting that the difference, 7.04 mcg was statistically significant. The study authors warn that: "Melamine tableware may release large amounts of melamine when used to serve high-temperature foods.”

#115 - Emergency Water Disinfection
In the event of a natural disaster, which may compromise your access to water from your tap or bottle source, follow these techniques to purify water for drinking:
Boiling - vigorously, for 10 minutes
Bleaching - add 10-20 drops of household bleach per gallon of water, mix well, and let stand for 30 minutes. A slight smell or taste of chlorine indicates water is good to drink. (Note: do not use scented bleaches, colorsafe bleaches, or bleaches with added cleaners.)
Tablets - commercially available purification tablets
Solar disinfection, known as SODIS - a new technique developed by researchers at the Swiss Federal Institute for Environmental Science and Technology. Clear plastic bottles are filled with water and left in the sun. The heat warms the water and the combination of warm water and ultraviolet radiation kills most microorganisms. The Institute’s tests showed that 99.9% of the E. coli in a sample of contaminated water were killed when the sun heated the water beyond 122F (50C). At that temperature, disinfection takes about an hour, but placing a corrugated metal sheet under the bottle can shorten the time. Additional tests demonstrate SODIS as an effective approach for killing the cholera bacteria, Vibrio cholerae, and that it could inactivate parasites including the diarrhea-causing Cryptosporidium.
