4. Toluene

Toluene is a naturally-occurring chemical found in crude oil and the tolu tree, and is used in the production of fuel, paints, paint thinners, nail polish, lacquers, adhesives, and rubber, according to ATSDR. This chemical is commonly found in the air, especially in places with a lot of vehicular traffic and can readily evaporate into the air. If you are exposed to this chemical, you can experience the following symptoms;

Limonene is a colourless liquid and is used as a solvent in degreasing metals prior to industrial painting, for cleaning in electronic and printing industries, and in paint as a solvent, according to the U.S. National Library of Medicine. It is also used in flavouring and adding scents in food, household cleaning products and perfumes. If one inhales this chemical in its gaseous state, they can experience the following symptoms;

• Breathing difficulties
• Skin irritation

In related news, the National Disaster Management Agency has already removed about 2.4 tonnes of chemical waste mixed with soil and sent more samples to the Johor Department of Chemistry for further analysis.

Let’s hope that the authorities are able to maximise clean-up efforts before this situation escalates even further.
