question: Why does the body get stained when exposed to the sun after touching lemons?
comment: Lime juice is phototoxic. You can even get second degree burn from it if you get a lot of juice and UVA exposure. They get activated by UV light, and penetrate your skin. They are reactive, and trigger the melamine reflex of your skin. Then sink deeper and start triggering immune response and inflammation. Basically, looks like a sunburn that continue developing up to 48h later. Wash with cold water (they react to heat too) and apply UVA blocking sunscreen to the area, to block further light from activating them.

   In 2001 the Trek deal proved painful for LeMond as he was forced by John Burke, the head of Trek, to apologize for the negative comments about Michele Ferrari, doping, and Lance Armstrong, who was by then a very important marketing force for Trek. LeMond's contract with Trek had a clause prohibiting LeMond from doing anything that would damage Trek. Burke reminded LeMond of this commitment, and strongly argued that LeMond publicly retract his statements. LeMond read a formal apology to Armstrong.
   Section::::Nutritional value.
  
  In contrast to the unpeeled lemon, the amount of vitamins within the preserved lemons is reduced, along with a loss of minerals and simple carbohydrates such as sugar and starch. 
  
  Section::::Physical and chemical changes.
  
  The process of fermentation is a complex one and causes a multitude of changes at the exterior and interior levels of the lemon. All of the known exterior changes are observable with the human eye. These changes include a wrinkling of the skin along with a slight browning of the interior portion of the lemon (if sliced), due to oxidation.
   During this period, Penone carried out his work on traces and imprints obtained using various procedures, all based on contact. They range from the technique of the mold or cast to different actions based on exerting pressure. In "Svolgere la propria pelle" ("Developing One's Own Skin"), a 1970 artwork published the following year in the form of an artist's book, Penone recorded the boundary of his body with hundreds of photos taken by superimposing a sheet of glass on his skin. "The animal image, the imprint is involuntary culture. It has the intelligence of the material, a universal intelligence, an intelligence of the flesh of the material of man. The imprint of the whole epidermis of one's body, a leap into the air, a plunge into water, the body covered with earth. Developing one's skin against the air, water, earth, rock, walls, trees, dogs, handrails, windows, roads, hair, hats, handies, wings, doors, seats, stairs, clothes, books, eyes, sheep, mushrooms, grass, skin ... " wrote the artist, reflecting on the quantity of voluntary and involuntary signs that bodies disseminate and spread on different things: the neon lights in a gallery, the panes of glass in a window at the Kunsthalle in Kassel at ""Documenta 5"" in 1972, on a stone in "Svolgere la propria pelle/pietra" ("Developing One's Own Skin/Stone") of 1971, or on the fingers in "Svolgere la propria pelle/dita" ("Developing One's Own Skin/Finger") of the same year.
   Lime pulp and peel contain diverse phytochemicals, including polyphenols and terpenes, many of which are under basic research for their potential properties in humans.
  
  Section::::Toxicity.
  
  Contact with lime peel or lime juice followed by exposure to ultraviolet light may lead to phytophotodermatitis, which is sometimes called margarita photodermatitis or lime disease (not to be confused with Lyme disease). Bartenders handling limes and other citrus fruits while preparing cocktails may develop phytophotodermatitis.
   The two parties first found themselves at odds in July 2001, after LeMond expressed public concern over the relationship between Italian doping doctor Michele Ferrari and Trek's star athlete, Lance Armstrong. "When I heard he was working with Michele Ferrari, I was devastated," LeMond was quoted as saying of Armstrong. "If Lance is clean, it is the greatest comeback in the history of sports. If he isn't, it would be the greatest fraud."
   BULLET::::- In 2001, shortly after LeMond made negative comments about doping doctor Michele Ferrari and Lance Armstrong, the complaint alleges that "Trek contacted Mr. LeMond to notify him that Mr. LeMond's comments in the article upset Mr. Armstrong".
  
  BULLET::::- The complaint states that in 2001 John Burke of Trek contacted LeMond and "wanted Mr LeMond to issue a statement that had been drafted for him" regarding the Armstrong/Ferrari comments, and that if a suitable press release was not made, "Mr. Armstrong would sever his relationship with Trek and Mr. LeMond's relationship with Trek would suffer."
   The Magnuson–Moss Warranty Act is a United States federal law enacted in 1975 to protect consumers from deceptive warranty practices. The Act was sponsored by Senator Warren G. Magnuson of Washington with co-sponsors Senator Frank Moss of Utah, and U.S. Representative John E. Moss of California. The purpose of the Act was to make product warranties more easily understood and enforceable, and to provide the Federal Trade Commission with a means of better protecting consumers. The Act does not force a manufacturer to include a warranty with its products but if there is one it must be in writing and comply with the rules of the Magnuson-Moss Warranty Act.

   Five years after Akerlof's paper was published, the United States enacted a federal "lemon law" (the Magnuson–Moss Warranty Act) that protects citizens of all states. There are also state laws regarding "lemons" which vary by state and may not necessarily cover used or leased vehicles. The rights afforded to consumers by "lemon laws" may exceed the warranties expressed in purchase contracts. These state laws provide remedies to consumers for automobiles that repeatedly fail to meet certain standards of quality and performance. "Lemon law" is the common nickname for these laws, but each state has different names for the laws and acts, which may also cover more than just automobiles. In California and federal law, "Lemon Laws" cover anything mechanical.
   The existence, scope and consequence of express and implied warranties can vary under state law, and warranties for the sale of goods will often be addressed by Article II of the Uniform Commercial Code. The Magnuson-Moss Warranty Act will not protect the buyer of a product purchased without a warranty, such as a product purchased "as is" or "with all faults", but may protect a consumer who was misled into waiving the protection of a warranty.

   The Eagleton Institute of Politics hosted a Science and Policy Workshop titled "Scientists in Politics" in late November 2018. Douglas Eveleigh and John Warhol participated, and informed the attendees about the history of microbiology in New Jersey and the importance of the State Microbe as a scientific and cultural symbol for New Jersey.
   Section::::Importance.
   The federal "lemon law" also provides that the warrantor may be obligated to pay the attorney fees of the party prevailng in a lemon , as do most state lemon laws. If a car has to be repaired for the same defect four or more times and the problem is still occurring, the car may be deemed to be "a lemon". The defect must substantially hinder the vehicle's use, value, or safety. Purchasers who knowingly purchase a car in "as is" condition accept the defects and void their rights under the "lemon law".

  Phototoxicity is a rash, swelling or inflammation, like a severe sunburn, caused by exposure to light following exposure to a chemical.
   Recently, a 2014 study shows that Argentine lemons contained excessive imazalil pesticide residues. Imazalil is a systemic fungicide, which is used post-harvest on bananas, citrus and as a pre-planting seed treatment of barley and wheat. The US Environmental Protection Agency (EPA) classifies imazalil as a likely human carcinogen, but it is not generally considered to be a dietary risk. The EPA allows for the presence of imazalil residue within certain tolerances in or on specific food commodities.
   LeMond talked about some of these issues in a 2012 interview with the Irish radio program "NewsTalk" as well.
   When in contact with the skin, the Key lime can sometimes cause phytophotodermatitis, in which a chemical reaction makes the skin extra sensitive to ultraviolet light.
  
  Section::::History.
  
  This particular cultivar is a citrus hybrid, "Citrus micrantha" × "Citrus medica" (a papeda-citron cross).
   After being hand-picked, the lemons are carefully transported to prevent even the slightest damage and, within a maximum of 24 hours of harvesting, they are peeled to obtain a very fine layer of zest, reducing the extraction of white pith as much as possible, to prevent the liqueur from having an excessively bitter after-taste.
   Section::::Symptoms.
  
  Though expressivity is varied depending on the mutation responsible for decrease in enzyme function, severe cutaneous sensitivity is present in most cases of this Porphyria. An estimated 30–40% of cases are due to the C73R mutation, which decreases stability of the enzyme and results in 1% of its activity. Exposure to long-wave ultraviolet light causes the affected skin to thicken and produce vesicles that are prone to rupture and infection; these secondary infections, along with bone resorption, can lead to disfigurement of the sun-exposed face and extremities.

   A third form of testing is the photoprovocation test which is used to identify disorders instigated by sun burns. The process of this test involves exposing one area of a patient's arm to certain dosage of UVB radiation and one area on the other arm to a certain dosage of UVA radiation. The amount of radiation that the patient is exposed to is equal to that "received in an hour of midday summer sun." If the procedure produces a rash, then the patient will undergo a biopsy. Finally, there are laboratory tests which generally involve procedures such as blood, urine, and fecal biochemical tests. In some situations, a skin biopsy may be performed.
