Chemical pollution is a serious threat to both human health and the environment. Industrial chemicals have permeated our bodies, with researchers describing babies born today as pre-polluted. To address this issue, individuals, governments, and businesses must work together to reduce toxic chemical use and implement preventive measures. Pollution prevention practices, such as source reduction, are more cost-effective and desirable than recycling, treatment, or disposal. This involves adopting less harmful pesticides, using non-toxic chemicals for cleaning and maintenance, and implementing energy and water conservation practices. Additionally, individuals can make a difference by recycling batteries, choosing safer cosmetics, and being mindful of the environmental impact of the chemicals they use. The European Green Deal and initiatives like MedWaves aim to drive the detoxification and decarbonization of economies, while organizations like CWR emphasize the importance of regulations that adopt the precautionary principle to manage toxic chemicals effectively.

Reduce toxic chemicals in the product design phase
The EU's chemicals strategy for sustainability aims to ensure that chemicals are produced and used in a way that maximises their contribution to society while minimising harm to the planet and its inhabitants. To achieve this, it is essential that product design incorporates sustainability dimensions that address chemical safety, recyclability, and environmental impact.
One approach is to establish a multidisciplinary design team, including product designers, material engineers, chemists, toxicologists, and sustainability experts. This team should employ safe and sustainable design methodologies, aiming to minimise the use of hazardous chemicals, reduce greenhouse gas emissions, and foster the reuse and recycling of materials.
To reduce toxic chemicals in the product design phase, several strategies can be implemented:
- Incorporate Environmental Design Principles: Design teams can adopt environmental design criteria, such as using recyclable materials, to reduce environmental risks and waste throughout a product's life cycle.
- Minimise Waste and Use Renewable Feedstocks: Design chemical syntheses to prevent waste generation and use renewable raw materials instead of depleting feedstocks derived from fossil fuels.
- Design for Degradability and Safety: Create chemical products that break down into innocuous substances after use, minimising environmental accumulation. Design products to be fully effective yet with minimal toxicity to humans and the environment.
- Analyse and Monitor: Implement real-time monitoring during syntheses to prevent or minimise the formation of harmful byproducts. Ensure appropriate handling of chemicals in their solid, liquid, or gas phases to reduce the potential for accidents, including explosions and environmental releases.
- Avoid Toxic Chemicals: Substitute hazardous chemicals with safer alternatives. For example, avoid using toxic pesticides and fertilisers, opting for crop strains with natural pest resistance.
- Foster Innovation: Encourage the development and utilisation of non-toxic materials and products. Innovate substitutes for currently used hazardous chemicals.
By implementing these strategies, we can reduce toxic chemicals in the product design phase, contributing to the broader goal of minimising chemical pollution and its adverse impacts on human health and the environment.

Avoid using harmful chemicals at home
Chemicals are used in the home every day, from cleaning fluids and paints to fuels and plastics. While most substances in our environment are likely safe, some can be toxic and cause adverse health effects, from minor irritations such as eye irritation and nasal congestion to major health risks like cancer and damage to the liver or central nervous system. Here are some ways to avoid using harmful chemicals at home:
Read Labels and Instructions Carefully
Before purchasing a product, read the label to identify any potentially harmful substances. When using a chemical product, follow the instructions carefully and be aware of any safety precautions. This includes wearing recommended protective equipment, such as gloves, safety goggles, and a face mask, and working in a well-ventilated area.
Store and Dispose of Chemicals Properly
Always store chemicals in sealed containers with proper labels and keep them out of the reach of children, preferably in a locked cabinet. Do not store chemicals in food or drink containers, as they may be mistaken for edibles. When you no longer need a chemical, dispose of it safely and responsibly. Take leaking, expired, or unused products to a local waste and recycling centre instead of pouring them down the drain.
Choose Greener Alternatives
Opt for environmentally friendly and non-toxic products whenever possible. For example, choose cleaning products, pesticides, and fertilizers with fewer chemicals. Use natural pest control methods, such as cultivating crop strains with natural resistance to pests. For personal care products, avoid those containing phthalates, as they have been linked to reproductive and developmental problems in animal studies.
Improve Ventilation and Air Quality
Keep your home well-ventilated by opening doors and windows to reduce the concentration of indoor pollutants. Place air-purifying plants or devices in your home to absorb and filter out harmful chemicals. Control humidity levels with a dehumidifier to reduce the presence of certain volatile organic compounds (VOCs).
Be Mindful of Hidden Chemicals
Be aware that chemicals can be found in unexpected places, such as mattresses, carpets, canned foods, and perfumes. For example, flame retardants are added to upholstery, curtains, and fabric blinds to prevent fires but have been linked to negative health effects. When purchasing new items, opt for natural materials like cotton, polyester, or wool instead of treated foams.

Use less toxic chemicals in industrial processes
The use of toxic chemicals in industrial processes can have far-reaching consequences for both human health and the environment. Toxic industrial chemicals (TICs) are used to create materials for manufacturing, combine materials, disinfect, lubricate, and more. These chemicals can be in the form of gases, liquids, or solids, and they pose a significant threat to human health and the environment.
To mitigate these risks, it is essential to adopt less toxic alternatives in industrial processes. This involves evaluating the health risks associated with all chemicals used and selecting those with lower toxicity levels. For instance, instead of using toxic pesticides, one could adopt less environmentally harmful alternatives or cultivate crop strains with natural resistance to pests. This approach not only reduces the environmental impact but also lowers the health risks for workers and nearby communities.
Additionally, it is crucial to implement effective controls to minimize employee exposure to toxic chemicals. According to OSHA, engineering and work practice controls should be the primary means of reducing employee exposure. This includes modifying production processes to produce less waste and implementing water and energy conservation practices. Reusing materials instead of disposing of them as waste can also help reduce the environmental footprint of industrial processes.
Furthermore, it is important to strengthen existing chemical laws and regulations. Regulatory bodies should consider the various ways people may be exposed to harmful chemicals when deciding whether to allow their use. By holding the chemical industry accountable and enforcing meaningful regulations, we can better protect communities from the harmful effects of toxic industrial chemicals.
In conclusion, reducing the use of toxic chemicals in industrial processes is crucial for safeguarding human health and the environment. By adopting less toxic alternatives, implementing effective controls, strengthening regulations, and promoting pollution prevention practices, we can significantly mitigate the adverse impacts of toxic chemicals on our planet and its inhabitants.

Regulate chemicals in groups, not individually
The concept of regulating chemicals in groups, rather than individually, is gaining traction as a necessary step to protect human health and the environment. This approach, known as regulating chemicals by class, is being considered by organisations such as the US Environmental Protection Agency (EPA) and the European Chemicals Agency (ECHA).
The current paradigm of assessing chemicals one at a time is inefficient and fails to acknowledge that humans and the environment are exposed to multiple chemicals simultaneously or in sequence. By regulating chemicals in groups, we can better address the cumulative impacts of chemicals and their interactions. This approach is particularly relevant given that certain chemicals behave similarly when they interact in the environment, such as organic chemicals in salt marshes or mercury in the atmosphere.
One example of a chemical group that warrants regulation is PFAS chemicals, which contain carbon and fluorine atoms, are widely used, and break down very slowly or not at all. There is growing evidence that thousands of PFAS chemicals should be regulated as a class to protect human health and the environment. However, a consistent definition of what constitutes a PFAS chemical is needed to effectively implement this regulation.
Additionally, the history of chemical regulation has been criticised for being too slow and reactive, often taking over a decade from the first evidence of harm to restricting problematic uses. By regulating chemicals in groups, we can send a strong signal to industries that replacing one chemical with similar chemicals is not a viable solution. This approach would encourage industries to assess the safety of chemicals more comprehensively and prevent the substitution of one harmful chemical with another.
Furthermore, the regulatory process can be streamlined by utilising tools such as read-across, which involves assuming that chemicals with similar structures have similar toxicological properties to the most toxic known substance in the group. This approach can increase regulatory efficiency and provide faster protection from harmful chemicals.

Adopt a circular economic model
The current linear production and consumption economic model has led to a heavy global environmental toll. The intensive use of primary resources and overconsumption are closely linked to climate change, biodiversity loss, large-scale pollution, and land-use change.
The circular economy is a proposed solution to these issues. It revolves around reducing, reusing, and recycling materials (known as the three R's). This approach turns the cradle-to-grave linear economic model into a never-ending closed circle of renewal. The three R's can be expanded to include "refuse," "repair," "refurbish," "remanufacture," and "repurpose," which are processes intended to increase sustainability at many levels.
The circular economy aims to eliminate waste and pollution, circulate products and materials, and regenerate nature. It is underpinned by a transition to renewable energy and materials. By shifting from a linear to a circular economy, the focus shifts from extraction to decoupling economic activity from the consumption of finite resources. This can help to reduce carbon emissions, cut greenhouse gas emissions, and improve air and water quality.
For example, electrifying the transportation sector can reduce fine particulate matter emissions by 22% and significantly improve air quality. Similarly, adopting circular economy practices can improve water supply quality through optimal wastewater management.
In addition to the environmental benefits, the circular economy can also drive economic growth and create jobs.
