A 1-year-old girl was diagnosed with lymphocytic leukemia, which is what we usually call leukemia. After ruling out a series of factors such as genetic history, the doctor initially concluded that it may be caused by excessive formaldehyde in the melamine tableware used when feeding.
Imitation porcelain tableware has become very popular in recent years, especially after adding some cartoon patterns, and it has become the most commonly used tableware for many children.
CCTV has reported on this before, and the results were shocking: when the quality inspection department conducted spot checks on melamine tableware on the market, the results showed that the pass rate was less than 20%.
Put six different brands of melamine tableware into boiling water and hot oil to measure the amount of formaldehyde released. The result was that after adding hot water, the formaldehyde release amounts of two of them were 0.10mg/m⊃3; and 0.12mg/m⊃3;; after adding hot oil, the formaldehyde release amount seriously exceeded the standard, and even more What's more, it reached 0.38mg/m⊃3; and 0.41mg/m⊃3;. According to relevant standards, the maximum allowable concentration of formaldehyde in indoor air is only 0.08mg/m⊃3;, which means it exceeds the standard by nearly five times.
As we all know, formaldehyde in melamine melamine tableware is a first-level carcinogen and can irritate our skin and mucous membranes. Once the formaldehyde concentration in melamine melamine tableware exceeds the standard, it may cause red eyes, throat discomfort, chest tightness and asthma. In severe cases, it can induce nasopharyngeal cancer, lymphoma, leukemia, etc.
