关于美国食品重金属新闻真实性考古
原文如下美国食品和药物管理局（FDA）近日发布食品安全报告称，在一些常见的食品中查出含量惊人的重金属物质，而婴幼儿食品是食品污染问题的“重灾区”。
美国食品和药物管理局发布的这份《饮食全面研究》报告表明，在他们收集的数千种食品样本中，15%的食品样本含铅，43%的样本含砷，61%的样本含镉。例如，金枪鱼罐头的砷含量惊人，可可粉、葵花籽的镉含量非常高。
在他们检测的384份婴幼儿食品样本当中：21%的婴幼儿食品样本含有铅，51%的食品样本含砷，65%的食品样本含镉，其中砷含量最高的食品样本出自婴儿麦片、磨牙饼干和一些膨化零食。另有3%的食品样本被检测出含汞。
科学家表明，有毒重金属会危害婴幼儿神经发育、影响大脑功能。

FDA Releases New Total Diet Study Report on Toxic Elements
TheFDAhas released their new Total Diet Study Report that focuses on the presence of toxic compounds in the foods we eat. The overall takeaway is that the key toxic elements were not detected in most (68%) of the tested foods. The analysis was conducted in foods that were collected from 2018 through 2020. Overall, 3,276 food, beverages, and water products were studied.
The key elements studied were lead, arsenic, including inorganic arsenic, the most dangerous form, cadmium, and mercury. Overall, lead was found in 15% of the samples, arsenic in 43%, cadmium in 61%, and mercury in 8%. The categories of food included in the study were alcohol, baked goods, baby food, beverages, candies, condiments, dairy, fruit, grains, meats, ingredients like sugar and flour, compound foods such as canned soups and meals, nuts, seeds, restaurant foods, sauces, seafood, vegetables, and water.
The foods that had the highest concentration of the elements were surprising. For lead, teething biscuits, sandwich cookies, white wine, low-calorie ranch dressing, and sweet potato based baby food had the highest levels of contamination. For arsenic, canned tuna, fish sticks, baked salmon, pre cooked shrimp, and canned tuna were problematic. For cadmium, spinach, sunflower seeds, potato ships, leaf lettuce, and French fries had the highest concentration. And for mercury, canned tuna, baked cod, baked salmon, cooked catfish, and precooked shrimp had the highest levels.
The FDA has set up action levels for some products; all of the results from those products fell below established levels. Those products include apple juice, chocolate and hard candy, and infant rice cereal.
In fact, infant and baby foods have been on the radar for heavy metal contamination for some time. In 2019, the FDA conducted more sampling for the Total Diet Study Report of these products. Of the 384 samples, 65% of the products had no detectable levels for lead, arsenic, mercury, and cadmium.

翻阅pdf报告查到了相关数据内容
Lead was detected in 15% of the samples with results ranging from ND to 164 ppb (the next highest
lead level detected was 63 ppb).
• Arsenic was detected in 43% of the samples with results ranging from ND to 10900 ppb (the next
highest arsenic level detected was 9100 ppb). The results of the subset of samples further analyzed
for inorganic arsenic ranged from 6.1 to 103 ppb (the next highest inorganic arsenic level detected was
90 ppb).
• Cadmium was detected in 61% of samples with results ranging from ND to 400 ppb (the next highest
cadmium level detected was 300 ppb).
• Mercury was only detected in 8% of samples, with results ranging from ND to 250 ppb (the next
highest level of mercury detected was 220 ppb)
