Naphthalene is a major component of some mothballs.It repels moths as well as some animals. [citation needed]Since mothballs that contain naphthalene are considered hazards, safer alternatives have been developed, such as the use of 1,4-dichlorobenzene, however, 1,4-dichlorobenzene has been declared as a potential neurotoxin. 1,4-dichlorobenzene has been linked to potentially causing ...
Older mothballs consisted primarily of naphthalene, but due to naphthalene's flammability, many modern mothball formulations instead use 1,4-dichlorobenzene.The latter formulation may be somewhat less flammable, although both chemicals have the same NFPA 704 rating for flammability.
Naphthalene's minimum odor threshold is 0.084 ppm for humans. [42] Mothballs and other products containing naphthalene have been banned within the EU since 2008. [43] [44] In China, the use of naphthalene in mothballs is forbidden. [45] Danger to human health and the common use of natural camphor are cited as reasons for the ban.
Naphthalene (the chemical used in mothballs) is considered more effective, but there are concerns over its effects on human health. Despite being commonly thought to be undertaken by all moths, [10] [11] only the larvae of several moth species eat animal fibres, creating holes in articles of clothing, in particular those made of wool. Most ...
This is a partial list of herbs and herbal treatments with known or suspected adverse effects, either alone or in interaction with other herbs or drugs.Non-inclusion of an herb in this list does not imply that it is free of adverse effects.
Although many people have a fear of mushroom poisoning by "toadstools", only a small number of the many macroscopic fruiting bodies commonly known as mushrooms and toadstools have proven fatal to humans. This list is not exhaustive and does not contain many fungi that, although not deadly, are still harmful.
