Editing Pyrethrum (section)

=== Mammals ===
Rat and rabbit {{LD50}} levels for pyrethrum are high, with doses in some cases of about 1% of the animal's body weight required to cause significant mortality. This is similar to fatal levels in synthetic pyrethroids.<ref>[http://edis.ifas.ufl.edu/pi091 Pesticide Toxicity Profile: Synthetic Pyrethroid Pesticides] {{Webarchive|url=https://web.archive.org/web/20210422160831/https://edis.ifas.ufl.edu/pi091 |date=2021-04-22 }}, by Frederick M.

People can be exposed to pyrethrum as a mixture of [[cinerin]], [[Jasmolone|jasmolin]], and [[pyrethrin]] in the workplace by breathing it in, getting it in the eyes or on the skin, or swallowing it. The [[Occupational Safety and Health Administration]] (OSHA) has set the legal limit ([[Permissible exposure limit]]) for pyrethrum exposure in the workplace as 5&nbsp;mg/m<sup>3</sup> over an 8-hour workday. The [[National Institute for Occupational Safety and Health]] (NIOSH) has set a [[Recommended exposure limit]] (REL) of 5&nbsp;mg/m<sup>3</sup> over an 8-hour workday. At levels of 5000&nbsp;mg/m<sup>3</sup>, pyrethrum is [[IDLH|immediately dangerous to life and health]]. People exposed to pyrethrum may experience symptoms including [[pruritus]] (itching), [[dermatitis]], [[papules]], [[erythema]] (red skin), [[rhinorrhea]] (runny nose), [[sneezing]], and [[asthma]].<ref>{{Cite web|title = CDC - NIOSH Pocket Guide to Chemical Hazards - Pyrethrum |url = https://www.cdc.gov/niosh/npg/npgd0685.html|website = www.cdc.gov|access-date=October 23, 2015}}</ref>
