Highly Toxic: a gas that has a LC 50 in air of 200 ppm or less. [2] NFPA 704: Materials that, under emergency conditions, can cause serious or permanent injury are given a Health Hazard rating of 3. Their acute inhalation toxicity corresponds to those vapors or gases having LC 50 values greater than 1,000 ppm but less than or equal to 3,000 ppm ...
The tree is recorded as the world's most dangerous tree by Guinness World Records. [ 28 ] In the television series Death in Paradise , Series 13, Episode 3, a person is killed by being small doses of poison from the tree.
This is the list of extremely hazardous substances defined in Section 302 of the U.S. Emergency Planning and Community Right-to-Know Act (42 U.S.C. § 11002).The list can be found as an appendix to 40 CFR 355. [1]

Lonomia obliqua has a toxic venom which causes disseminated intravascular coagulation and a consumptive coagulopathy, which can lead to a hemorrhagic syndrome. The toxins are stored in sacs at the base of each spine. As the spines penetrate the victim, venom flows through the hollow bristles and into the puncture wound. [7]
Toxins can be further differentiated into subtypes on the bases of smaller variations. [13] However, all types of botulinum toxin are rapidly destroyed by heating to 100 °C for 15 minutes (900 seconds). 80 °C for 30 minutes also destroys BoNT. [14] [15] Most strains produce one type of BoNT, but strains producing multiple toxins have been ...
Numerous animal species naturally produce chemical toxins which are used to kill or incapacitate prey or as a defense against predators. Venomous animals actively deliver their toxins (called venom ) into their target through a specially designed mechanism, such as a bite or sting , by using a venom apparatus , such as fangs or a stinger , in a ...
