【求助】“pyrene不在reach限制范围之内” 这句话怎么翻译好

这句话本身就有语病吧？什么意思呢？

Pyrene, is not in the scope of restricted requirement of REACH regulation.

这么解释吧，比如说reach要求对猪牛羊鸡鸭进行限制，凡是有上述动物的都不能出口，但pyrene可以。pyrene不在reach限制范围之内。

有劳了，谢谢。

可否理解为：Reach法规不适用于pyrene呢？也就是Reach regulation is not applicable for pyrene?

REACH regulation is applicable for all chemical substances, and articles.
As continue of previous chemical requirement 76/769/EEC, REACH has a restricted substance list, and pyrene is not in the list.

既然reach适用于所有的化学产品，怎么pyrene又不在reach限制范围内呢？
可以说pyrene不在restricted substance list上，也就是not listed

So, REACH is applicable for all chemicals, including pyrene, but for certain usage, REACH has launched a restricted list, and Pyrene, is not in the list.

Pyrene is exempted from the restriction of REACH.

Pyrene is excluded from the restriction of REACH.
