a cooking appliance which uses natural gas, propane, butane, liquefied petroleum gas or other flammable gas as a fuel source. 
Often preferred by professional chefs and enthusiastic cooks, gas stoves are known to deliver accurate cooking temperatures and do not heat up the kitchen to unbearable levels while in operation. Still they present the potential risk of carbon monoxide (CO) poisoning, if are not properly installed, maintained and operated. 
According to a study published in Environmental Health Perspectives in 2013 gas stoves could also give off unhealthy levels of nitrogen dioxide (NO2) and formaldehyde. Emissions of CO and formaldehyde were generally low. But emissions of NO2 may surpass the acceptable limits for outdoor air established by the Environmental Protection Agency. 

Foods, beverages or inhaled heat raising body temperature. 
Spicy dishes can produce a burning sensation when tasted, stimulating the circulation and raising internal body temperatures. So do liquids and solids  having a high degree of heat or a high temperature.
Victims of conflagration frequently sustain pulmonary injuries that are of equal or greater imlportance to survival than are the burns received on the surface of the body. At any given temperature moist air has more heat to give up than does an equal volume of dry air and is accordingly more likely to cause thermal injury of the respiratory tract. Inhalation of dry or moist hot air may destroy the upper tracheal mucosa without causing primary thermal injury of the lungs. when the original temperature of the air is high enough to produce almost instantaneous burning of the skin and upper respiratory mucosa.

Heavy silvery-white transition metal  (atomic number 80, 1 ppm = 100 mcg per 100 g), liquid at ordinary temperatures. Historically, mercury or one of its compounds were used medicinally, especially to treat syphilis.
Liquid mercury is slightly toxic, while its vapor, compounds and salts are highly toxic and have been implicated as causing brain and liver damage when ingested, inhaled or contacted. The inhalation of mercury vapor can produce harmful effects on the nervous, digestive and immune systems, lungs and kidneys, and may be fatal. The inorganic salts of mercury are corrosive to the skin, eyes and gastrointestinal tract, and may induce kidney toxicity if ingested.
Once in the environment, mercury can be transformed by bacteria into methylmercury that can bioaccumulate in fish and shellfish. Large predatory fish are more likely to have high levels of mercury as a result of eating many smaller fish that have acquired mercury through ingestion of plankton.

Organic compound with the formula CH₂=CCOOCH₃, CAS 80–62–6 Used in n chain-addition polymerizations, in the manufacture of methacrylate resins and plastics (e.g., Plexiglas; advertising signs and displays, lighting, plumbing and bathroom fixtures; lacquer, and enamel resins; concrete additives, and prosthetic medical devices - such as hip and knee joint prostheses). It can be detected in small concentrations in human breath - Streptococcus pneumonia infections, for example, increase its concentrations up to 1420 ppb.
Methyl methacrylate is a flammable and reactive chemical, fire and explosion hazard. Breathing it in can irritate the lungs causing coughing and or shortness of breath. Higher exposures can cause a build up of fluid in the lungs and pulmonary edema. It can affect liver and kidneys, damage nervous system, causing numbness, “puns and needles”, and/or weakness in the hands and feet, and may cause a skin allergy. High exposure can cause dizziness, irritability, difficulty with concentration and reduced memory. Workplace exposure limits are 100 ppm over 8 hrs shifts or 50 ppm if longer term exposures. 

Molds are forms of fungi that can be found almost anywhere, indoors and outdoors. They can grow on virtually any organic substance, as long as moisture and oxygen are present. There are molds that can grow on wood, paper, carpet, foods, and insulation. Different types of mold - black, green, white and orange mold, toxic mold, allergenic mold - are present all the time around us and in the air we breathe. Molds can appear fuzzy or in slimy streaks. The most common indoor molds are Cladosporium  (textiles and dump materials), Penicillum (wallpaper, decaying fabrics, carpet, and fiberglass duct insulation), Aspergillus (house dust)  Penicillium, Aspergillus (house dust), and Alternaria. commonly found inside nose, mouth and upper respiratory tract . It can cause allergic responses.

Molds are associated with musty or earthy odors.  In low levels, molds and mold spores are generally harmless but if their levels increase they can affect people; especially people with allergies, asthma and respiratory conditions or suppressed immune system. 

stale,  moldy, earthy or dump smell, often associated with "unclean" or "spoiled". 

Chemicals causing musty smells are mostly produced by Actinomycetes, Streptomyces, Cyanobacteria and other bacteria, fungi and algae. Examples of compounds responsible for musty odor are Geosmin (muddy, resembling damp soil, produced by Streptomyces), trichloroanisole (TCA, smelling like damp cellar, usually produced from chlorinated phenolic compounds by Aspergillus, Penicillium, Actinomycetes, Botrytis cinerea, Rhizobium, or Streptomyces), tribromoanisole (TBA, produced from brominated phenolic compounds by the same bacteria), dimethylmethoxypyrazine (obnoxious musty odor that might be caused by Pseudomonas and Actinobacteria), 2-methylisobomeol (earthy, peat-like), 3-methylbut-2-ene-1-thiol, cis-3-octenal, nonanal, decanal. ​
Indoor mildew odor in old houses has been shown to be associated with allergic symptoms, asthma, chronic bronchitis, vision and sleep issues. 

The vocal or instrumental sound producing  beauty of form, harmony, and expression of emotion.
Loudness of music is a subjective measure. 
Objective measures are: sound pressure, sound intensity or sound power. The decibel (dB) is logarithmic unit of sound intensity; 10 times the logarithm of the ratio of the sound intensity to some reference intensity.
Music can be divided into different genres in several ways.

synthetic rubber-like material, resistant to oil, heat, water, and weathering. Neoprene is the generic name for an organic polymer called polychloroprene, typically built from the monomer 2-chloro-1,3-butadiene.
Neoprene is used for face masks, dish-washing gloves (as an alternative to latex), scuba wet suits, leggings, skirts,  pants, t-shirts and other clothing. Neoprene is also known as "Mixed dialkyl thioureas (MDTU), "leather of the summer" or "scuba".  
Neoprene is water resistant, temperature controlling and flexible which makes it a perfect material for things like computer sleeves, wet suits, athletic shoes, gloves and knee braces. Neoprene traps warm air between the fibers or a thin layer of water between the suit and the wearer's skin that helps to keep the wearer warm. Sensitivity to neoprene might be exacerbated by sweating and could elicit redness, itching, scaling and sometimes blistering.  

Group of genetically-diverse single-stranded RNA viruses comprising the Norwalk virus, which can cause inflammation of the stomach and large intestine lining (gastroenteritis). Also known as Norwalk-like virus, "small, round-structured virus" (SRSV), Spencer flu, "Snow Mountain virus", "winter vomiting bug", and "stomach flu", but the latter refers to a range of viruses and bacteria.
​
Norovirus is a very contagious virus that can infect anyone, mainly by person-to-person contact or by contaminated food and water. Norvovirus (NoVs) is classified into at least five types (genogroup I [GI] to genogroup V [GV]) and 34 genotypes. Human NoVs are in GI, GII, and GIV. In addition, NoVs have been detected in pigs (GII), cows (GIII), mice (GV), large carnivores (GIV.2) and dogs (GIV.2) and can spread easily across a group of animals.
The virus causes your stomach or intestines or both to get inflamed. This leads you to have stomach pain, nausea, and diarrhea and to throw up. These symptoms can be serious for some people, especially young children and older adults.
