要去一家碳素厂工作,他们生产炭黑之类的东西,用在轮胎添加等.可能还有一些其它的炭产品,请问:这些东西对人体健康有没有影响的??如果是,大型企业有没有可能预防得很好呢??再有,我是库管.谢谢啦...

毒性不大，主要是粉尘危害。国家规定：车间空气中炭黑粉尘的最高容许浓度为8mg/m3。
避免尘扬和良好的通风是关键。3M的N95口罩是必要劳保用品。
MSDS中这样描述：
Toxicology
IARC evaluation: possible human carcinogen (Group 2B). May be harmful by ingestion or inhalation. Respiratory irritant. Typical STEL 7 mg/m3. Note: Carbon black is generally made under controlled conditions, and has a high carbon content. By contrast, soot usually contains additional complex organic molecules, some of which may be carcinogenic. Thus, industrial and domestic soot may be presumed to present a greater risk to human health than commercially-produced carbon black.

有没有毒我不知道，但最好戴口罩，灰尘多对呼吸道不好

有毒
