Dirt is unclean matter, especially when in contact with a person's clothes, skin or possessions when they are said to become dirty. Common types of dirt include:
- dust — a general powder of organic or mineral matter
- filth — foul matter such as excrement
- grime — a black, ingrained dust such as soot

Exhibitions and studies
A season of artworks and exhibits on the theme of dirt was sponsored by the Wellcome Trust in 2011. The centrepiece was an exhibition at the Wellcome Collection showing pictures and histories of notable dirt such as the great dust heaps at Euston and King's Cross in the 19th century and the Fresh Kills landfill which was once the world's largest.[1]
Foci
Computer keyboards are especially dirty as, on average, they contain 70 times more microbes than a lavatory seat.[2]
Cleaning
When things are dirty they are usually cleaned with solutions like hard surface cleaner and other chemicals; much domestic activity is for this purpose — washing, sweeping and so forth.[3]
In a commercial setting, a dirty appearance gives a bad impression. An example of such a place is a restaurant. The dirt in such cases may be classified as temporary, permanent and deliberate. Temporary dirt is streaks and detritus that may be removed by ordinary daily cleaning. Permanent dirt is ingrained stains or physical damage which require major renovation to remove. Deliberate dirt is that which results from design decisions such as decor in dirty yellow or grunge styling.[4]
Disposal
As cities developed, arrangements were made for the disposal of dirt. In Britain, the Public Health Act 1875 required households to place their refuse into a container which could be moved so that it could be carted away. This was the first legal creation of the dustbin.[5]
Health
Modern society is now thought to be excessively clean. Lack of contact with microorganisms in dirt when growing up is hypothesised to be the cause of the epidemic of allergies such as asthma.[6] The human immune system requires activation and exercise in order to function properly and exposure to dirt may achieve this.[7] For example, the presence of staphylococcus bacteria on the surface of the skin regulates the inflammation which results from injury.[8]
People and animals may eat dirt. This is thought to be caused by mineral deficiency and so the condition is commonly seen in pregnant women.
Neurosis
People may become obsessed by dirt and engage in fantasies and compulsive behaviour about it, such as making and eating mud pies.[9] The source of such thinking may be genetic, as the emotion of disgust is common and a location for it in the brain has been proposed.[10]
