The main sources of benzene pollution are:

Decoration pollution:

Widely used in decoration materials, paints, coatings, adhesives, etc. can cause varying degrees of residual pollution.

Mixed pollution: the mixture of urban living areas and industrial areas. Industrial waste gas pollution leads to air pollution,

Supermarkets and shopping malls in living areas, such as packaging bag pollution in supermarkets
