求翻译：老化的多环芳烃（包括菲和芘）对蚯蚓的生物有效性降低都是上述的原因，只是HPCD提取量可以代表蚯蚓对菲的生物有效性，不能代表蚯蚓对芘的生物有效。是什么意思？

正在翻译，请等待...

Aging of PAHs and sanitary accommodation (including biological effectiveness) of earthworms are lowering the above reasons, only HPCD extraction can be representative of earthworms in Philippines, biological effectiveness cannot be representative of the earthworm biological effective.

The aged multi-link aromatic hydrocarbon (including the Philippines and pi) reduces to earthworm's biological validity all is the above reason, only is the HPCD extraction quantity may represent the earthworm to Philippines's biological validity, cannot represent the earthworm to pi the biology is e

Aging of polycyclic aromatic hydrocarbons (including phenanthrene and pyrene) to reduce the bioavailability of earthworms are all of the above reasons, HPCD extracts bioavailability of phenanthrene on behalf of the earthworm, not on behalf of the earthworm pyrene bio is valid.
