Toxicological Profile - Succinctly characterizes the toxicologic and adverse health effects information for a hazardous substance. Minimal Risk Levels MRL - The MRL is an estimate of the daily human exposure to a hazardous substance that is likely to be without appreciable risk of adverse, non-cancer health effects over a specified duration of exposure. The information in this MRL serves as a screening tool to help public health professionals decide where to look more closely to evaluate possible risk of adverse health effects from human exposure.

It can also cause dermatitis, nausea, confusion, jaundice, and coma. Hexane evaporates very quickly and so the most common exposure is from breathing air containing hexane. It can also enter via the skin. The most probable route of human exposure to hexane is by inhalation. Individuals are most likely to be exposed to hexane in the workplace. Monitoring data indicate that hexane is a widely occurring atmospheric pollutant.
Safe Work Australia sets the workplace exposure standard for n-hexane through the workplace exposure standards for airborne contaminants :. These standards are only appropriate for use in workplaces and are not limited to any specific industry or operation. Make sure you understand how to interpret the standards before you use them.
There is no guideline for n-hexane in the Australian Drinking Water Guidelines. Because of its very low solubility in water and high volatility, it will usually be rapidly transported to the atmosphere without major damage to the biota. In the atmosphere it is one of the volatile organic substances that contribute to the formation of photochemical smog, through interaction with nitrogen dioxide and ozone.
Hexane is carried in the air. If released to soil, hexane will usually quickly evaporate to the atmosphere. Hexane is only slightly soluble in water, but is readily absorbed by the lipid phase fatty parts of aquatic organisms, which can result in transport in the environment.
Due to its high volatility and low solubility in water, hexane in the environment will be mainly in the atmosphere. In the atmosphere, hexane is expected to exist almost entirely in the vapour phase due to its relatively high vapour pressure. The dominant tropospheric loss process for hexane is by reaction with the hydroxyl OH radical. The calculated half-life and lifetime of hexane due to reaction with the OH radical are 1. The products of the OH radical-initiated reaction include 2-hexanone, 2- and 3-hexyl nitrate and 5-hydroxypentanone.
Releases from industries producing, using or handling hexane. For example, rubber and plastics products industries, oil refineries, chemical plants, footwear manufacturing, petrol, and paints and adhesives. Releases from service stations; evaporation of fuels during petrol refilling; underground storage tanks that leak. Releases during use of adhesives, paints, and paint thinners.
Hexane is a natural constituent of crude petroleum. It also occurs naturally as a plant volatile and can be released from volcanoes. Also occurs naturally in, forest fires, and some plants. Consumer products that contain small amounts of n-hexane include petrol, rubber cement, type-over correction fluids, non-mercury low temperature thermometers, alcohol preparations, and aerosols in perfumes.
