碲和碲化合物被认为有轻度[[毒性]]，需要小心处理，尽管急性碲中毒很少见。<ref name="Harrison">{{Cite web|last1 = Harrison|first1 = W.|first2 = S.|last2 = Bradberry|first3 = J.|last3 = Vale|title = Tellurium|publisher = [[International Programme on Chemical Safety]]|date = 1998-01-28|url = http://www.intox.org/databank/documents/chemical/tellur/ukpid84.htm|access-date = 2007-01-12|archive-date = 2008-12-10|archive-url = https://web.archive.org/web/20081210104352/http://www.intox.org/databank/documents/chemical/tellur/ukpid84.htm|dead-url = no}}</ref>碲中毒非常难以治疗，因为在治疗金属中毒时使用的许多[[螯合剂]]都会增加碲的毒性。碲没有致癌的报道。<ref name="Harrison"/>

人类暴露于含碲低至0.01mg/m<sup>3</sup>或更少的空气中就会散发出类似[[大蒜]]的恶臭，称为“碲口气”。<ref name=CRC>{{RubberBible86th}}</ref><ref name="Distillations">{{cite journal |last1=Kean |first1=Sam |title=The Scent of a Molecule |journal=Distillations |date=2017 |volume=3 |issue=3 |page=5 |url=https://www.sciencehistory.org/distillations/magazine/the-scent-of-a-molecule |access-date=2018-05-16 |archive-date=2021-11-05 |archive-url=https://web.archive.org/web/20211105033735/https://www.sciencehistory.org/distillations/magazine/the-scent-of-a-molecule |dead-url=no }}</ref>
这是由于身体将碲从任何氧化态转化为[[二甲基碲]]（(CH<sub>3</sub>)<sub>2</sub>Te）导致的。二甲基碲是一种挥发性的化合物，具有刺鼻的大蒜味。尽管碲的代谢途径未知，但通常认为它类似于研究更广泛的[[硒]]，因为这两种元素的最终甲基化代谢产物相似。<ref>{{Cite journal|pmid = 5911055|journal = American Journal of Physiology.

人们可以通过吸入、摄入、皮肤接触和眼睛接触在工作场所接触碲。[[美国职业安全与健康管理局]] (OSHA) 将工作场所中的碲暴露量限制（[[允许暴露极限]]）为八小时工作日里 0.1&nbsp;mg/m<sup>3</sup>。[[美国国家职业安全卫生研究所]] (NIOSH) 将八小时工作日的{{le|推荐暴露限值|recommended exposure limit}} (REL) 设为 0.1&nbsp;mg/m<sup>3</sup>。在25&nbsp;mg/m<sup>3</sup>的浓度下，碲就会{{le|立即危及生命或健康|immediately dangerous to life and health}}。<ref>{{Cite web|title = CDC – NIOSH Pocket Guide to Chemical Hazards – Tellurium|url = https://www.cdc.gov/niosh/npg/npgd0587.html|website = www.cdc.gov|access-date = 2015-11-24|archive-date = 2021-11-05|archive-url = https://web.archive.org/web/20211105030552/https://www.cdc.gov/niosh/npg/npgd0587.html|dead-url = no}}</ref>
