三聚氰胺中毒的症状和迹象有哪些？
尽管科学家说吸入少量三聚氰胺不危险，而由于没有三聚氰胺对人体影响的检测，科学家不能给出准确的定义。
But while scientists say it's not dangerous to ingest small amounts, they cannot be definitive because there have been no tests on melamine's effects in humans.
正如我上月所提到的，在动物饲料中发现三聚氰胺也就意味着三聚氰胺极有可能已扩散进入食物链的其它环节，例如肉类和蛋类中。
As I wrote last month, the discovery of melamine in animal feed means that it has likely spread to other parts of the food chain including meat and eggs.
山德罗夫说，检测出的三聚氰胺“含量非常低”，很可能是产品在加工或包装过程中接触到了三聚氰胺。
Sundloff said the melamine detected was at 'extremely low levels' and likely was the result of contact with melamine during the processing or from packaging.
目前有一个并非基于动物研究的三聚氰胺的数额限值，但我们不能确定，即使是这少量的数额是否对人类来说就是安全的，尤其是经过长年累月的摄取三聚氰胺。
There is a limit that is not based on animal studies, but we can't be certain that even the small amount is safe in humans, especially if consumption of the chemical goes on for years.

当存在三聚氰胺时，溶液的颜色将在几秒钟之内迅速从红色变为蓝色，而且能够同时通过肉眼观察和分光光度法检测到。
When melamine is present, the color of the solution changes from red to blue within seconds and can be measured both by visual inspection and spectrophotometry.
然而，一份对于64份研究报告的分析表明，含有1%到6%的氰笨甲酮的防晒品并不会对大多数人的皮肤造成过敏或刺激。
However, a recent analysis of 64 studies indicates that sunscreens with 1 to 6 percent oxybenzone don't pose a significant risk of skin sensitization or irritation for most people.
