A '''Poisonpoison''' is aany [[chemical substance]] that hasis aharmful detrimentalor effect[[Lethality|lethal]] to life[[Organism|living organisms]]. The term is used in a wide range of [[Branches of science|scientific fields]] and industries, where it is often specifically defined. It may also be applied [[colloquial]]ly or figuratively, with a broad sense.
 
Whether something is considered a poison mayor changenot may dependingdepend on the amount, the circumstances, and what living things are present. [[Poisoning]] could be accidental or deliberate, and if the cause can be identified there may be ways to neutralise the effects or minimise the [[symptoms]].
 
In [[biology]], a poison is a [[chemical substance]] causing [[death]], injury or harm to [[organism]]s or their parts. In [[medicine]], poisons are a kind of [[toxin]] that are delivered passively, not actively. In industry the term may be negative, something to be removed to make a thing safe, or positive, an agent to limit unwanted [[pest (organism)|pests]]. In [[ecology|ecological terms]], poisons introduced into the environment can later cause unwanted effects elsewhere, or in other parts of the [[food chain]].
 
==Modern definitions==
Line 15 ⟶ 16:
In [[biology]], poisons are [[Chemical substance|substances]] that can cause [[death]], injury, or harm to [[organs]], [[Tissue (biology)|tissues]], [[Cell (biology)|cells]], and [[DNA]] usually by chemical reactions or other [[activity (chemistry)|activity]] on the [[molecular]] scale, when an organism is exposed to a sufficient quantity.<ref>[http://www.merriam-webster.com/dictionary/poison "Poison"] at ''Merriam-Webster''. Retrieved December 26th, 2014.</ref>
 
[[Medicinal]] fields (particularly [[veterinary medicine]]) and [[zoology]] often distinguish poisons from ''[[toxins]]'' and ''[[venoms]]''. <u>Both</u> poisons and venoms are toxins, which are [[toxicant]]s produced by organisms in nature.<ref name=AustralianAcademyOfSciencePoisonvsVenom>{{cite web|title=Poison vs. Venom|work=[[Australian Academy of Science]]|date=3 November 2017 |url=https://www.science.org.au/curious/people-medicine/poison-vs-venom|access-date=17 April 2022}}</ref><ref name="Chippaux Goyffon 2006 pp. 215–20">{{cite journal|last1=Chippaux|first1=JP|last2=Goyffon|first2=M|title=[Venomous and poisonous animals--I.

==Uses==
[[Industrial sector|Industry]], [[agriculture]], and other sectors employ many poisonous substances, usually for reasons other than their [[toxicity]] to humans.

[[Pesticide]]s are one group of substances whose prime purpose is their toxicity to various insects and other animals deemed to be pests (e.g., [[rat]]s and [[cockroach]]es) is their prime purpose. Natural pesticides have been used for this purpose for thousands of years (e.g. concentrated [[table salt]] is toxic to many [[slug]]s and [[Snail|snails]]). [[Bioaccumulation]] of chemically-prepared agricultural [[insecticide]]s is a matter of concern for the many species, especially [[bird]]s, which [[insectivore|consume insects]] as a primary food source. Selective toxicity, controlled application, and controlled [[biodegradation]] are major challenges in [[herbicide]] and pesticide development and in [[chemical engineering]] generally, as all lifeforms on earth share an underlying [[biochemistry]]; organisms exceptional in their environmental resilience are classified as [[extremophile]]s, these for the most part exhibiting radically different susceptibilities.
 
==Ecological lifetime==
A poison which enters the [[food chain]]—whether of industrial, agricultural, or [[plant defense against herbivory|natural]] origin—might not be immediately toxic to the first organism that [[foodborne illness|ingests]] the toxin, but can become further concentrated in [[predator]]y organisms further up the food chain, particularly [[carnivore]]s and [[omnivore]]s, especially concerning [[fat soluble]] poisons which tend to become stored in biological tissue rather than excreted in [[urine]] or other water-based [[excretion|effluents]].
 
Apart from food, many poisons readily enter the body through the [[skin]] and [[lung]]s. [[Hydrofluoric acid]] is a notorious contact poison, in addition to its [[corrosion|corrosive]] damage. Naturally occurring [[sour gas]] is a notorious, fast-acting atmospheric poison, (aswhich can be released by [[volcanic]] activity or [[drilling rig]]s). Plant-based contact irritants, such as that possessed by [[poison ivy]] or [[poison oak]], are often classed as [[allergen]]s rather than poisons; the effect of an allergen being not a poison as such, but to turn the body's [[immune system|natural defenses]] against itself. Poison can also enter the body through faulty [[implant (medicine)|medical implants]], or by [[injection (medicine)|injection]] (which is the basis of [[lethal injection]] in the context of [[capital punishment]]).
 
In 2013, 3.3 million cases of unintentional human poisonings occurred.<ref>{{cite journal|authorsauthor=((Global Burden of Disease Study 2013 collaborators)) |title=Global, regional, and national incidence, prevalence, and years lived with disability for 301 acute and chronic diseases and injuries in 188 countries, 1990-2013: a systematic analysis for the Global Burden of Disease Study 2013|journal=Lancet|date=22 August 2015|volume=386|issue=9995|pages=743–800|pmid=26063472|doi=10.1016/s0140-6736(15)60692-4|pmc=4561509}}</ref> This resulted in 98,000 deaths worldwide, down from 120,000 deaths in 1990.<ref name=GDB2013>{{cite journal|authorsauthor=((GBD 2013 Mortality and Causes of Death collaborators)) |title=Global, regional, and national age-sex specific all-cause and cause-specific mortality for 240 causes of death, 1990-2013: a systematic analysis for the Global Burden of Disease Study 2013|journal=Lancet|date=17 December 2014|pmid=25530442|doi=10.1016/S0140-6736(14)61682-2|volume=385|issue=9963|pages=117–71|pmc=4340604}}</ref> In modern society, cases of [[suspicious death]] elicit the attention of the [[Coroner]]'s office and [[forensic science|forensic investigators]].
 
Of increasing concern since the isolation of natural [[radium]] by [[Marie Curie|Marie]] and [[Pierre Curie]] in 1898—and the subsequent advent of [[nuclear physics]] and nuclear technologies—are [[radioactive contamination|radiological poisons]]. These are associated with [[ionizing radiation]], a mode of toxicity quite distinct from chemically active poisons. In [[mammal]]s, chemical poisons are often passed from mother to offspring through the [[placenta]] during gestation, or through [[breast milk]] during [[breastfeeding|nursing]]. In contrast, radiological damage can be passed from mother or father to offspring through genetic [[mutation]], which—if not fatal in [[gestation|miscarriage]] or [[list of genetic disorders|childhood]], or a direct cause of [[infertility]]—can then be passed along again to a subsequent generation. Atmospheric [[radon]] is a natural radiological poison of increasing impact since humans moved from [[hunter-gatherer]] lifestyles thoughand [[cave dweller|cave dwelling]] to increasingly enclosed structures able to [[radium and radon in the environment|contain radon]] in dangerous concentrations. The 2006 [[poisoning of Alexander Litvinenko]] was a novelnotable use of radiological assassination, presumably meant to evade the normal investigation of chemical poisons.
 
Poisons widely dispersed into the environment are known as [[pollution]]. These are often of [[human impact on the environment|human origin]], but pollution can also include unwanted biological processes such as toxic [[red tide]], or acute changes to the natural chemical environment attributed to [[invasive species]], which are toxic or detrimental to the prior ecology (especially if the prior ecology was associated with human economic value or an established industry such as [[shellfish]] harvesting).

==Etymology==
The word "poison" was first used in 1200 to mean "a deadly potion or substance"; the English term comes from the "...Old French poison, puison (12c., Modern French poison) "a drink", especially a medical drink, later "a (magic) potion, poisonous drink" (14c.), from Latin potionem (nominative potio) "a drinking, a drink", also "poisonous drink" (Cicero), from potare "to drink".<ref name="etymonline.com">{{cite web|url=http://www.etymonline.com/index.php?allowed_in_frame=0&search=poison|title=poison - Search Online Etymology Dictionary|website=www.etymonline.com|access-date=3 November 2017}}</ref> The use of "poison" as an adjective ("poisonous") dates from the 1520s. Using the word "poison" with plant names dates from the 18th century. The term "[[poison ivy]]", for example, was first used in 1784 and the term "[[poison oak]]" was first used in 1743. The term "[[poison gas]]" was first used in 1915.<ref name="etymonline.com"/>

==Terminology==
Line 49 ⟶ 45:
(see [[median lethal dose]]). The term "poison" is also used in a figurative sense: "His brother's presence poisoned the atmosphere at the party". The law defines "poison" more strictly. Substances not legally required to carry the label "poison" can also cause a medical condition of poisoning.
 
Some poisons are also toxins, which is any poison produced by animals,an vegetables or bacteriaorganism, such as the [[bacteria]]l [[protein]]s that cause [[tetanus]] and [[botulism]]. A distinction between the two terms is not always observed, even among scientists. The derivative forms "toxic" and "poisonous" are synonymous. Animal poisons delivered [[subcutaneously]] (e.g., by [[sting (biology)|sting]] or [[bite]]) are also called ''venom''. In normal usage, a poisonous organism is one that is harmful to consume, but a venomous organism uses venom to kill its prey or defend itself while still alive. A single organism can be both poisonous and venomous, but thatit is rare.<ref>{{cite journal |vauthors=Hutchinson DA, Mori A, Savitzky AH, Burghardt GM, Wu X, Meinwald J, Schroeder FC |title=Dietary sequestration of defensive steroids in nuchal glands of the Asian snake Rhabdophis tigrinus |journal=Proceedings of the National Academy of Sciences of the United States of America |volume=104 |issue=7 |pages=2265–70 |year=2007 |pmid=17284596 |pmc=1892995 |doi=10.1073/pnas.0610785104 |bibcode=2007PNAS..104.2265H |doi-access=free }}</ref>
 
All living things produce substances to protect them from getting eaten, so the term "poison" is usually only used for substances which are poisonous to humans, while substances that mainly are poisonous to a common pathogen to the organism and humans are considered [[antibiotic]]s. Bacteria are for example a common adversary for ''[[Penicillium chrysogenum]]'' mold and humans, and since the mold's poison only targets bacteria, humans may use it for getting rid of bacteriait in their bodies. Human [[antimicrobial peptide]]s which are toxic to viruses, fungi, bacteria, and cancerous cells are considered a part of the immune system.<ref name="pmid15555874">{{cite journal|vauthors=Reddy KV, Yedery RD, Aranha C | title= Antimicrobial peptides: premises and promises| journal=International Journal of Antimicrobial Agents | year= 2004 | volume= 24 | issue= 6 | pages= 536–547 | pmid=15555874 | doi=10.1016/j.ijantimicag.2004.09.005}}</ref>
 
In [[nuclear physics]], a [[nuclear poison|poison]] is a substance that obstructs or inhibits a nuclear reaction.
Line 57 ⟶ 53:
[[Environmentally hazardous]] substances are not necessarily poisons, and vice versa. For example, food-industry wastewater—which may contain potato juice or milk—can be hazardous to the ecosystems of streams and rivers by consuming oxygen and causing [[eutrophication]], but is nonhazardous to humans and not classified as a poison.
 
Biologically speaking, any substance, if given in large enough amounts, is poisonous and can cause death. For instance, [[Water intoxication|several kilograms worth of water would constitute a lethal dose]]. Many substances used as medications—such as [[fentanyl]]—have an {{LD50}} only one order of magnitude greater than the [[Effective dose (pharmacology)|ED50]]. An alternative classification distinguishes between lethal substances that provide a therapeutic value and those that do not.
 
==Poisoning==
{{Main|Poisoning}}
[[File:Saka-saka - cassava leaves in mortar and pestle.jpg|thumb|[[Cassava]] leaves contain [[cyanide]] and can thus cause poisoning if not prepared correctly.]]
 
Poisoning can be either acute or chronic, and caused by a variety of natural or synthetic substances. Substances that destroy tissue but do not absorb, such as [[lye]], are classified as [[corrosive]]s rather than poisons.
 
Line 79 ⟶ 77:
 
=== Chronic ===
 
[[File:Lagoa vermelha na Mina do Losal 05.jpg|thumb|[[Groundwater pollution|Polluted groundwater]], in this case depicting [[acid mine drainage]], can cause chronic poisoning.]]
 
Chronic poisoning is long-term repeated or continuous exposure to a poison where symptoms do not occur immediately or after each exposure. The person gradually becomes ill, or becomes ill after a long latent period. Chronic poisoning most commonly occurs following exposure to poisons that [[bioaccumulate]], or are [[biomagnification|biomagnified]], such as [[mercury (element)|mercury]], [[gadolinium]], and [[lead]].
