What are organic solvents

What is an organic solvent

An organic solvent is a type of volatile organic compound (VOC). VOCs are organic chemicals which vaporise at room temperature.

Organic compounds used as solvents include:

  • aromatic compounds, eg benzene and toluene
  • alcohols, eg methanol
  • esters and ethers
  • ketones, eg acetone
  • amines
  • nitrated and halogenated hydrocarbons.

Organic solvents are often used:

  • to dissolve substances
  • to disperse coatings
  • as media for chemical reactions
  • as cleaning agents.

They are also often used in the manufacture of pharmaceutical products, footwear, paints, varnishes and adhesives.

Organic solvents react in the atmosphere in sunlight, producing an air pollutant known as 'ground-level ozone'. High concentrations of ground-level ozone seriously affect human, animal and plant health. They also harm building materials, forests and crops.

Many organic solvents are classified as toxic or carcinogenic. They can cause significant air and water pollution, and land contamination.

  • A day with Hydrology, SEPA's hydrometry unit is responsible for around 400 gauging stations and 350 rainfall monitoring sites. River gauging stations are important as they allow river levels to be monitored so flood events can be predicted and flood warnings sent out.

  • Brewing and Distilling Technical Drop-in Day: Waste, Water, Energy, Brewing and Distilling is booming due to high demand for quality Scottish beers and spirits. All this growth is also leading to a boom in food waste, energy and water use.
