Summary of Key Points
This article challenges the reporting logic and core evidence presented by journalist Wang Wenzhi regarding the hot topic of "toxic diapers causing the detection of formaldehyde in infants' bodies." It raises various issues, including inconsistencies in his statements, unverified blood testing methods, unknown sources of baseline formaldehyde levels, conflicting results from different industries and institutions, and doubts about the credibility of the infant blood test results. The article argues that the foundational evidence for this report is weak and that there may even be suspicions regarding the authenticity of the evidence itself.
Detailed Analysis
1. Inconsistent Statements and Changing Toxicology Conclusions
Journalist Wang initially stated on social media that the levels of formaldehyde detected in infants' bodies were sufficient to cause harm, implying a judgment on whether the dose was toxic. However, in subsequent interviews, he changed his stance, claiming, "I don't make quantitative toxicological determinations; the key point is that formaldehyde was detected." This approach of reaching a conclusion first and then shifting responsibility is problematic, similar to saying, "This cup of water is too hot to drink," only to later say, "I didn't say it's hot; I just said there's water in it"—a contradiction that significantly undermines the credibility of the report.
2. Two Major Flaws in Blood Testing: Unknown Baseline and Unscientific Methods
Wang used his own experience of wearing diapers overnight, resulting in a rise in blood formaldehyde levels from 2000 ng/mL to 4000 ng/mL, to prove the impact of diapers. However, there are two critical issues:
- Unknown Baseline: Experts state that the human body does not naturally contain formaldehyde; where did the 2000 ng/mL level come from before wearing the diapers? Was it due to eating something, or was it a testing error? Wang never explained this and only focused on the doubling of the levels, which is like saying your weight increased after eating without mentioning what your initial weight was.
- Unverified Testing Methods: No academic papers on the detection of formaldehyde in human blood can be found online, indicating that these testing methods have not undergone any basic scientific validation. Using such unproven results to establish a causal relationship is like using an uncalibrated thermometer to measure body temperature—how credible is that?
3. Conflicting Test Results from Diapers and Other Institutions
Wang claimed that multiple well-known brands of diapers contained high levels of formaldehyde, but industry experts and other testing organizations reached the opposite conclusion:
- Diaper manufacturers argue that formaldehyde is not added during production as it would reduce efficiency and increase costs.
- Other institutions used standard methods to test mainstream brands and found no evidence of formaldehyde. Instead of questioning his own tests, Wang blamed the methodology, suggesting that other tests were unscientific or missed the presence of formaldehyde—this is like saying a restaurant's food is poisonous when all ten customers consumed it without any issues.
4. Lack of Basis for Infant Blood Tests and Unclear Definitions of "Positive" Results
The core claim of detecting formaldehyde in infants' bodies also has significant flaws:
- Blood testing for formaldehyde is not a recognized medical procedure, and there are no established standards for what constitutes a "positive" result (for example, what level of ng/mL would be considered positive?).
- Wang argued that multiple institutions' findings supported his conclusion, but if the testing methods are flawed, repeated errors by different organizations still lead to incorrect results—just like using a wrong formula to solve math problems, the outcomes will be incorrect regardless of consistency.
5. AI-Generated Evidence Goes Unquestioned
The only screenshot of the elevated blood formaldehyde levels in the report bears an "AI-generated" watermark from "DouBaoAI." Test reports are serious scientific evidence; how can they be produced by AI? This obvious discrepancy has not been questioned by any journalist, which is astonishing.
Conclusion
In summary, this critical article points out that Wang's report is riddled with flaws, from the lack of scientifically validated testing methods to a logical inconsistency. The absence of basic rigor in media reporting is evident, which is why it has sparked widespread skepticism.
