The Impact of Aerosols on the Environment
Often overlooked, aerosols are tiny particles that have significant implications on climate change, air quality, ecosystem health and global weather patterns. Every spray of your deodorant, body spray or hairspray can make an awful lot of difference. But that’s not all. Aerosols go beyond your typical cans. They also include pollutants and even exist naturally in the environment. In this guide, we explore the multifaceted environmental impact of aerosols and their intricate relationship with our planet’s delicate ecological balance.

What are Aerosols?: They’re More Than Just Spray Cans
You probably think of deodorant or body sprays when you picture an aerosol but they are more than that. Aerosols are microscopic particles suspended in the atmosphere, ranging from natural sources like volcanic ash, sea spray and desert dust to human-made pollutants such as smoke, soot and industrial emissions. Aerosols can come from a range of sources including:
Natural Sources:
- Volcanic eruptions
- Desert dust storms
- Forest fires
- Sea spray
- Pollen and plant debris
- Microbial organisms
Human-made Sources:
- Industrial emissions
- Vehicle exhausts
- Agricultural burning
- Construction activities
- Chemical manufacturing
- Fossil fuel combustion
- Beauty and cleaning products
Aerosol Cans and the Ozone Layer
You’ve probably heard of the ozone layer and the fact that there’s a hole in it. But how did this happen?
The ozone layer is a critical component of Earth’s stratosphere. This thin layer of ozone (O3) molecules plays a crucial role in protecting life on Earth by absorbing most of the sun’s harmful ultraviolet (UV) radiation.
However, there are particular aerosols that can cause ozone to deplete. For example, chlorofluorocarbons (CFCs), historically found in refrigeration, air conditioning and aerosols, are known to break down in the stratosphere and release chlorine atoms. These chlorine atoms become free radicals—essentially, they are now searching for something to react with. The chlorine radicals react with ozone molecules, breaking ozone into oxygen, and destroying the ozone layer.
But, the hole in the ozone layer has shown signs of recovery. With global policies and coordinated action, the ban on CFCs globally has meant the ozone layer can begin to repair itself with research showing the hole should be fully healed by 2066.
Nevertheless, modern aerosols still contain harmful chemicals that can affect the ozone layer. VOCs, or volatile organic compounds, are chemicals that can deplete the ozone layer, contribute to bad air quality and cause respiratory problems in humans.
The Complex Cooling and Warming Effects of Aerosols
One of the most intriguing aspects of aerosols is their dual role in climate dynamics. Some aerosols have a cooling effect, while others contribute to global warming. Weird, right?
The Cooling Effect of Aerosols
Despite what you might think, certain aerosols, particularly sulfate aerosols from volcanic eruptions and industrial processes, actually cause a cooling effect. They do this by reflecting sunlight back into space. Thai reflective property can temporarily reduce global temperatures. For example, the 1991 Mount Pinatubo eruption in the Philippines released massive amounts of sulfur dioxide, which cooled global temperatures by approximately 0.5°C for two years.
The Warming Effect of Aerosols
But where there’s good, there’s also bad. Some aerosols, also known as black aerosols which are commonly produced by diesel engines, wood burning and other industrial processes, can absorb solar radiation. This aerosol spray pollution contributes to atmospheric warming and can accelerate ice and snow melting, particularly in polar regions. Not so good…
Aerosol Dangers: The Impact on Air Quality and Human Health
Aerosols are not just an environmental concern; they directly affect human health too! Fine particulate matter can penetrate deep into human lungs, causing respiratory issues, cardiovascular problems and other health complications.
Especially in urban areas with high industrial and vehicular activity, people often experience severe air quality challenges due to aerosol concentrations. Megacities in developing countries also frequently struggle with dangerous levels of particulate matter, leading to increased health risks for millions of people.
Ecosystem Disruption
The environmental effects of aerosols extends beyond climate and human health. It can also affect various ecosystems and, as a result, the living organisms that inhabit these areas.
Agricultural Implications
- Aerosols can alter precipitation patterns
- Reduced sunlight penetration also affects photosynthesis
- Changes in atmospheric composition impact crop yields and plant growth
Marine Ecosystem Effects
- Ocean microorganisms are sensitive to aerosol composition
- Nutrient distribution and marine food chains can disrupted
- Increased acidification from certain aerosol interactions
Biodiversity Challenges
- Shifts in temperature and precipitation patterns
- Habitat modifications due to increased temperatures
- Alternated migration and breeding cycles for various species
Global and Local Policy and Mitigation Strategies
Addressing the environmental effects of aerosols requires a multi-layered, collaborative approach that spans international and national levels. Simply switching to roll-on deodorant just won’t do!
International Policy Frameworks
- The Paris Agreement (2015): This is a comprehensive climate change mitigation treaty that included some aerosol-related provisions including encouraging the reduction of black carbon emissions, supporting the transition to low-emission industrial processes and providing a framework for tracking particular matter reductions.
- The Stockholm Convention on Persistent Organic Pollutants (2001): Another global treaty, this particular convention specifically addresses aerosol-producing chemicals and includes key objectives such as phasing out specific industrial processes that create aerosols, implementing strict monitoring mechanisms and protecting human health and the environment from long-lasting chemical emissions.
Specific Aerosol Policies in the UK
- Clean Air Strategy (2019): This ambitious national plan aims to reduce air pollution by targeting particulate matter emissions. Specific goals include reducing emissions from domestic burning, implementing stricter industrial emissions controls and developing urban air quality improvement plans.
- Environment Act 2021: This act introduced legally binding targets for air quality improvement and established the Office for Environmental Protection. Targets were set to reduce fine particulate matter including local air quality management requirements and mandatory reporting of environmental impact.
- Net Zero Strategy (2021): This comprehensive approach to reducing carbon emissions includes an indirect impact on aerosol reduction through transitioning to renewable energy, using electric vehicles for transport, supporting low-carbon industrial processes and investing in clean technology innovation.
- Urban Air Quality Initiatives: Clean air zones have been introduced in major cities across the UK including London, Birmingham and Manchester. These initiatives restrict high polluting vehicles from entering these areas, place charges on vehicles depending on their emissions and create incentives for low-emission transportation.
How You Can Help as a Washroom Manager
You might be thinking, what has this got to do with me? After all, washrooms don’t cause aerosol pollution! Or do they? What about the air fragrancing systems you have in place or even the cleaning products you use? These could all create harmful aerosol spray pollution! Here’s how you can make more responsible choices when it comes to managing your washroom.
- Product Selection: Replace your traditional aerosol air fresheners with eco-friendly aerosols such as our air fragrancing range that is CFC-free and Carbon Footprint Approved.

FAQs
Why are aerosols bad?
Some aerosols harm human health and ecosystems, while others disrupt climate patterns by either warming or cooling the atmosphere. Older aerosols, which contain CFCs, can even cause detrimental damage to the ozone layer. They also contribute to acid rain and reduce air visibility.
How do aerosols affect human health?
Inhaling fine aerosols or fine particles can penetrate deep into the lungs, worsening respiratory and cardiovascular diseases. Long-term exposure is also linked to asthma, lung cancer and premature death.
How long do aerosols stay in the air?
Smaller aerosols can linger for days to weeks, travelling long distances, while larger particles can settle within hours. Their lifespan depends on size, wind and weather conditions if sprayed outside.
