Knowing what hazardous chemicals you’re using, their risks and how to safely dispose of them is a non-negotiable.

Check out this toxic chemicals list for the most commonly used dangerous chemicals across industries, along with the latest regulatory changes impacting 2026.

Toxic Chemicals List: 21 Dangerous Chemicals Used in Industries

This list includes the most common examples of toxic chemicals used in manufacturing, construction, agriculture, chemicals and pharmaceuticals. It includes descriptions of its uses, applications, and reasons for classification as toxic.

1. Asbestos – used in insulation and fireproofing for buildings. Inhaling it causes mesothelioma and lung cancer. Phase-out in many nations but still exists in older buildings.
2. Lead – Used in batteries, paints, pipes and bullets. Neurological damage (particularly in children), kidney damage, reproductive problems.
3. Mercury – Thermometers, fluorescent lamps, dental filling, electric switches. Toxic to the central nervous system and kidney. Builds up in the food chain via water pollution.
4. Benzene – Intermediate for plastics, synthetic fibers, rubber, solvents and pesticides. Causes leukemia and bone marrow failure. Greatly affects respiratory and immune systems.
5. Arsenic – Used as pesticides, wood preservatives, glass and semiconductors. Responsible for skin and bladder cancer, heart problems. Arsenic is a water contaminant in developing countries.
6. Chromium (VI) – Use as stainless steel, tanning and chrome plating industry, pigments. Causes cancer, lung disease and skin ulcers.
7. Polychlorinated Biphenyls (PCBs) – once used as an insulator in transformers and capacitors. Banned in most regions. Causes cancer, bioaccumulate, and damage the immune system and reproductive organs.
8. Cadmium – Used in nickel-cadmium batteries, paint, plastic stabilisers and pigments. Causes chronic kidney disease, osteoporosis, and lung cancer. Writes in soil and water and damages vegetation.
9. Formaldehyde – Resins, adhesives and medical laboratories use formaldehyde as a preservative. Known to cause respiratory problems, and nose and throat cancers.
10. Ammonia – Used as a refrigerant, in fertilizers, cleaning agents and nitric acid production. Respiratory issues, eye and skin irritation and severe chemical burns at high levels.
11. Toluene – Used as a solvent, in glue and paint thinners. Causes CNS damage, dizziness, headaches and can lead to neurological damage.
12. Hydrochloric Acid – Steel pickling, cleaning and process chemical. A highly corrosive acid, it burns skin and causes lung damage by inhalation.
13. Phthalates – Found in soft plastics (PVC), cosmetics and medical equipment. Hormone disruptors that cause hormonal and reproductive issues.
14. Dioxins – A byproduct of chemical and pesticide production. Highly toxic – cause cancer, reproduction and immune dysfunction. Present in the environment and food chain.
15. Cyanide – Used in the extraction of gold, electroplating, and synthesis of chemicals. Quickly lethal at high doses, via inhibition of respiration.
16. Chlorine – Used as a disinfectant, in water purification, and to produce PVC. Respiratory problems, skin irritation, and lung damage at high concentrations.
17. Ethylene Oxide – Ethylene oxide (EO) is a sterilant for medical equipment, a fumigant, and used to make antifreeze. Carcinogenic and causes lung and respiratory problems.
18. Perchloroethylene (PERC) – Dry cleaning and degreasing solutions, stain removers. Causes respiratory illness and dizziness, and impairs neurological function with long-term exposure.
19. Sulfuric Acid (Battery acid) – Found in fertilizer, battery acid and chemical production. It’s very corrosive – causing severe burns and lung damage.
20. Isocyanates: Used in production of polyurethane foam, coatings and adhesives. A top cause of occupational asthma. Potent respiratory sensitizer at low levels.
21. PFAS (“Forever Chemicals”) – found in frying pans, food packaging, textiles, firefighting foam and many other products. Don’t naturally degrade. Causes cancer, liver damage, thyroid problems, and weakens the immune system. The most regulated group of toxic chemicals of 2025-2026, with EPA setting maximum contaminant levels for PFOA and PFOS in drinking water, 18 states banning their use, and the EU launching a near-complete ban under the REACH chemicals regulation.

The PFAS Story: Why It Matters in 2026

PFAS warrant special attention because no other class of chemicals is seeing so much attention in the regulatory arena.

Almost 350 PFAS-related bills were introduced in 39 US states in 2025 alone. Already, states including Maine, Minnesota, Colorado and Vermont have banned PFAS use in cookware, food packaging, cosmetics, textiles and cleaning products, with further bans scheduled between 2024 and 2032. On a national level, the US Environmental Protection Agency (EPA) finalised drinking water criteria for six PFASs and lists 206 PFASs in the Toxic Release Inventory.

And under the REACH system, the EU is banning almost all uses of PFAS, with ongoing assessment by sector. Bans on firefighting foam came into effect in April 2016.

If your company makes, imports or uses products containing PFAS, the TSCA Section 8(a)(7) reporting deadline is fast approaching – from early 2027 onwards. Firms that haven’t begun searching their supply chains for PFAS have fallen behind.

Safe Disposal of Hazardous Materials

Dumping dangerous chemicals doesn’t just pose a risk to the environment – it poses a risk to business. The following are the most common methods of environmentally and legally approved disposal of hazardous chemicals.

Incineration

Heats chemicals to high temperatures, which converts them to ash, water and gases. Works well for organic chemical wastes like PCBs, dioxins and solvent wastes. The trade-off is emissions – carbon dioxide and potentially other pollutants – which need to be addressed by emission control technologies.

Chemical Neutralization

Neutralizes pollutants by reacting them with other substances to make them harmless. Works for corrosive chemicals:

• Hydrochloric acid with sodium hydroxide or calcium carbonate
• Sulfuric acid is neutralized with lime or soda ash
• Ammonia is neutralized with dilute acids

Needs to be monitored to ensure that all acid is neutralised and no toxic byproducts are produced.

Bioremediation

Involves the use of microorganisms or plants to remove or break down pollutants in soil and water. An environmentally friendly and cost effective method, effective for organic contaminants such as benzene, toluene and some petroleum hydrocarbons. It may not be suitable for all soils and contaminants due to temperature, soil type, and contaminant concentrations.

Secure Landfilling

Waste buried in isolated, impermeable landfills with leachate collection and groundwater monitoring. Landfills are used for stabilized waste that can’t be incinerated or neutralized. Must be permitted by EPA and individual states.

Recycling and Recovery

Certain hazardous wastes can be recovered:

• Batteries are recycled to reclaim lead
• Fluorescent light bulbs have the mercury removed
• PERC can be reclaimed via distillation
• Battery cadmium goes to recycling

Recovery cuts disposal fees and demand for new materials.

Regulatory Developments To Know

When working with toxic chemicals examples in an industrial environment, it’s important to keep up with regulatory developments. Here’s what you need to know now:

• EPA’s TSCA PFAS Rule – reporting period delayed until January 2027, but businesses should start now
• OSHA’s Process Safety Management (PSM) – if more than 10,000 pounds of ammonia or other substances are on-site
• EPA’s TRI program – 206 listed PFAS, more in 2016
• State product bans on PFAS – 18 states have bans; more planned by 2027
• EU REACH PFAS restriction – under sector-by-sector assessment, nearly complete ban in development
• GHS labeling regulations – all chemicals must be labeled in the Globally Harmonized System

Conclusion

All industries use hazardous chemicals. Construction, pharmaceuticals, farming, electronics, textiles – none can exist without exposure to some of the chemicals on this list. It’s not a question of whether you work with dangerous chemicals. It’s how you store, use and dispose of them so your employees, the community, and your organisation don’t suffer if you do it wrong.

In 2016 the list of dangerous chemicals isn’t getting shorter. In fact, the recognition of PFAS covering active regulation regimes mean that compliance is even harder. When it comes to industrial chemicals, it’s not enough for businesses to rely on suppliers with the right credentials and documentation (SDS, COA, regulatory compliance certifications). Its the baseline.
