精萘對(duì)人體有多種危害，主要包括：

　　Naphthalene poses various hazards to the human body, including:

　　急性中毒：短時(shí)間內(nèi)吸入大量萘蒸氣或粉塵，可能導(dǎo)致眼及呼吸道刺激、角膜混濁、頭痛、惡心、嘔吐、食欲減退、腰痛、尿頻等癥狀。嚴(yán)重時(shí)可能出現(xiàn)中毒性腦病、肝損害、溶血性貧血及肝、腎損害，甚至導(dǎo)致急性腎功能衰竭和肝壞死。

　　Acute poisoning: Inhaling large amounts of naphthalene vapor or dust in a short period of time may cause symptoms such as eye and respiratory irritation, corneal opacity, headache, nausea, vomiting, decreased appetite, lower back pain, and frequent urination. In severe cases, toxic encephalopathy, liver damage, hemolytic anemia, liver and kidney damage, and even acute renal failure and liver necrosis may occur.

　　慢性中毒：長(zhǎng)期接觸萘蒸氣可能引起頭痛、乏力、惡心、嘔吐和血液系統(tǒng)損害，如白細(xì)胞減少、血小板減少等。還可能引起白內(nèi)障、視神經(jīng)炎和視網(wǎng)膜病變，以及皮炎。

　　Chronic poisoning: Long term exposure to naphthalene vapor may cause headaches, fatigue, nausea, vomiting, and blood system damage, such as leukopenia, thrombocytopenia, etc. It may also cause cataracts, optic neuritis, retinopathy, and dermatitis.

　　致癌作用：高濃度的精萘可能誘發(fā)肝癌和肺癌等癌癥。

　　Carcinogenic effects: High concentrations of naphthalene may induce cancers such as liver cancer and lung cancer.

　　生殖毒性：影響男性和女性的生殖能力、性腺功能和胎兒發(fā)育。

　　Reproductive toxicity: affects the reproductive ability, gonadal function, and fetal development of both males and females.

　　呼吸系統(tǒng)危害：長(zhǎng)時(shí)間吸入精萘蒸氣會(huì)引發(fā)哮喘和其他呼吸系統(tǒng)問題。

　　Respiratory hazards: Long term inhalation of naphthalene vapor can cause asthma and other respiratory problems.

　　因此，在接觸精萘?xí)r，必須采取適當(dāng)?shù)姆雷o(hù)措施，如佩戴過濾式防毒面具、空氣呼吸器和化學(xué)防護(hù)眼鏡，并在工作現(xiàn)場(chǎng)加強(qiáng)通風(fēng)和個(gè)人防護(hù)。

　　Therefore, appropriate protective measures must be taken when in contact with refined naphthalene, such as wearing filter gas masks, air respirators, and chemical protective goggles, and strengthening ventilation and personal protection at the work site.
