Reducing Biogenic Pollutants: A Guide To Help The Environment

Biogenic emissions are those that come from natural sources, such as vegetation, soils, volcanic emissions, lightning, and sea salt. These emissions are considered in photochemical grid models as they are widespread contributors to background air chemistry. One type of biogenic emission is biogenic volatile organic compounds (BVOCs), which lead to fine particulate matter and ground-level ozone pollution, particularly in urban areas. To reduce biogenic pollutants, individuals can take several actions, such as reducing car usage, switching to electric vehicles, using energy-efficient appliances, and supporting renewable energy sources. Additionally, individuals can advocate for policies that address air pollution and promote sustainable practices, like the development of Clean Air Zones.

Reduce car usage

Motor vehicles are a significant source of air pollution. Vehicle exhaust is a major contributor, with cars, trucks, and buses powered by fossil fuels emitting harmful pollutants. These include particulate matter, volatile organic compounds, nitrogen oxides, carbon monoxide, sulfur dioxide, and greenhouse gases. To reduce biogenic pollutants, it is essential to minimise car usage and adopt more sustainable transportation options. Here are some ways to reduce car usage and lower your environmental impact:

Opt for Walking or Cycling:

Instead of driving short distances, consider walking or cycling to your destination. These zero-emission modes of transportation can help you stay active and reduce your carbon footprint. By leaving your car at home, you will emit zero pollutants and improve air quality, especially in urban areas.

Embrace Public Transportation:

Utilise public transportation options such as buses, trains, or subways whenever possible. These modes of transport allow multiple people to travel together, reducing the number of cars on the road. Public transportation can also be more efficient in terms of fuel consumption and emissions per passenger, contributing to lower biogenic pollutants.

Carpool and Ride-Sharing:

If public transportation is not accessible, explore carpooling options with friends, colleagues, or neighbours. Sharing rides reduces the number of vehicles on the road and can lead to significant emission reductions. Additionally, ride-sharing services are becoming increasingly popular and provide a convenient way to reduce the number of cars on the road.

Work Remotely and Optimise Trips:

If your job allows it, consider working from home periodically. This reduces the need for daily commutes and can lead to substantial emission savings. Additionally, when you do need to drive, try to optimise your trips by combining multiple errands or tasks into one journey. This approach reduces the number of individual trips and lowers overall emissions.

Choose Fuel-Efficient Vehicles:

When it comes to purchasing a new vehicle, opt for fuel-efficient cars with low greenhouse gas emissions. Electric vehicles, hybrid cars, and even compact fuel-efficient gas vehicles can significantly reduce emissions and save you money on fuel costs. These vehicles are becoming more affordable and widely available, making them a more accessible choice.

Maintain Your Vehicle:

Regular maintenance and proper care of your vehicle can also reduce emissions. Keep your car in good repair, follow the manufacturer's maintenance schedule, and ensure proper tyre inflation. A well-maintained vehicle runs more efficiently and emits fewer pollutants. Additionally, modern vehicles have complex emission controls, so it's important to address any "check engine" lights promptly.

By implementing these changes and reducing car usage, you can play a significant role in lowering biogenic pollutants and improving air quality. These steps not only benefit the environment but also contribute to a healthier and more sustainable future for everyone.

Switch to electric vehicles

Motor vehicle emissions are the most significant source of common air pollutants. Transportation is a major contributor to pollution, and electric vehicles (EVs) are an essential part of a clean energy future.

EVs have no tailpipe emissions, which means they emit no pollutants from their exhaust pipes. This is in contrast to traditional gasoline or diesel vehicles, which emit harmful pollutants such as nitrogen oxides (NOx) and volatile organic compounds (VOCs) that contribute to air pollution and have negative impacts on human health.

EVs are more energy-efficient than traditional vehicles. They use approximately 87-91% of the energy from their batteries and regenerative braking for propulsion, compared to gasoline vehicles, which only convert about 16-25% of the energy from gasoline into movement. This higher energy efficiency leads to lower greenhouse gas emissions, even when accounting for the electricity used for charging.

The environmental benefits of EVs depend on how the electricity used to power them is generated. If electricity generation involves burning fossil fuels like coal or natural gas, it will result in carbon pollution. However, if electricity is generated from renewable sources like wind or solar power, EVs can be even greener. In 2020, renewable energy sources became the second most prevalent source of electricity in the US, and as the power grid continues to adopt more renewable energy sources, the environmental benefits of EVs will only increase.

To support the adoption of EVs, governments and organizations are taking initiatives to improve EV charging infrastructure. For example, the US government has invested up to $7.5 billion to build a national network of electric vehicle chargers. Additionally, most EVs can be charged using a standard 120-volt outlet, and dedicated 240-volt outlets or charging systems can be installed for faster charging.

By switching to electric vehicles, we can significantly reduce biogenic pollutants from transportation. This not only helps improve air quality but also contributes to the fight against climate change.

Improve energy efficiency

Improving energy efficiency is a highly effective way to reduce biogenic pollutants. Energy efficiency is about using less energy to achieve the same result, which in turn reduces energy costs and helps combat climate change.

There are many ways to improve energy efficiency, especially in buildings and transportation. Here are some strategies:

Buildings

• Appliances: Replace old appliances with energy-efficient models. Look for the ENERGY STAR label when purchasing new appliances, as these products are independently certified to use less energy. Examples include washing machines, refrigerators, ovens, and dishwashers.
• Lighting: Switch from incandescent light bulbs to LED bulbs. LED bulbs use up to 90% less energy to produce the same amount of light.
• Insulation: Add insulation to your home to reduce the amount of energy needed for heating and cooling.
• Windows and Skylights: Upgrade to energy-efficient windows and skylights to minimize heat loss and gain.
• Water Heaters: Traditional water heaters can be replaced with heat pump technology, which is more efficient and does not produce greenhouse gas emissions.

Transportation

• Electric Vehicles: Switch to an electric vehicle, which produces fewer emissions than traditional cars with internal combustion engines.
• Public Transport: Opt for public transportation, such as buses, trains, or subways, whenever possible to reduce the number of vehicles on the road.
• Carpooling: If you must drive, consider carpooling with friends or coworkers to reduce the number of cars on the road.
• Biking and Walking: For short trips, choose to walk or bike instead of driving. This helps reduce vehicle emissions and also improves your health.

By implementing these strategies, we can significantly improve energy efficiency, reduce biogenic pollutants, and create a more sustainable future.

Plant trees

Planting trees is a great way to help reduce biogenic pollutants. Trees act as the "'lungs' of an ecosystem, absorbing carbon dioxide (CO2) and releasing oxygen into the atmosphere. They also act as a natural "liver", filtering atmospheric pollutants like sulphur dioxide and nitrogen dioxide through their leaves. Trees are particularly effective at removing particulate matter (PM) from the air, which includes particles made from a mixture of different chemicals and soot that can cause heart and lung disease.

Trees can improve air quality in both direct and indirect ways. Directly, they remove pollutants from the air through the interception of particulate matter on plant surfaces and the absorption of gaseous pollutants through the leaf stomata. Indirectly, they can provide shade, reducing the need for conventional air conditioning and the emissions associated with it. Lower temperatures also decrease the risk of harmful pollutants like ground-level ozone, which often spikes on hot days in urban areas.

When it comes to choosing which trees to plant, some species are more effective than others at filtering pollutants. Conifers, such as pines and cypresses, are good natural purifiers due to their dense canopy of needle-like leaves, which effectively trap pollutants. Additionally, as an evergreen species, they provide year-round filtration. Other effective species include silver birch, yew, and elder trees, which have hairy leaves that trap particles.

It's important to consider the local context when selecting tree species. Native trees may be more suitable for a particular ecosystem, and factors such as wind direction and landscape structure can impact how pollution moves, influencing the placement of trees for optimal effect. Urban planners should also ensure biodiversity by not having more than 5-10% of an urban forest composed of the same species or family.

By planting trees, we can make a significant contribution to reducing biogenic pollutants and improving the air quality in our communities.

Avoid backyard burning

Backyard burning is a significant source of air pollution, especially in metro areas. It releases harmful pollutants at ground level, which are easily inhaled and can cause serious health issues. Backyard burning includes burning household trash, leaves, and wood in a burn barrel, wood stove, or fire pit.

Understand the Dangers of Backyard Burning

Firstly, it is important to recognize the negative impact of backyard burning. Burning trash produces hazardous air pollutants (HAPs), particle pollution, and volatile organic compounds (VOCs). These pollutants can cause serious health issues for you, your family, and your community. Backyard burning releases toxins such as dioxins, which are persistent and bioaccumulative, remaining in the environment for extended periods and increasing in concentration as they move up the food chain. Dioxins can cause immune system suppression, disrupt hormonal systems, and lead to cancer. Particle pollution can cause respiratory problems, cardiac issues, and impact vulnerable individuals such as children, the elderly, and those with existing conditions.

Reduce Waste and Recycle

Instead of burning trash, focus on reducing waste and recycling as much as possible. Look for items with less packaging or opt for packaging that can be reused or recycled. Reuse waste whenever possible, such as old paper, cans, or plastic bags. Donate old clothes or give them to thrift stores rather than burning them. Recycle items like plastic, glass, aluminum cans, cardboard, and paper. Check with your local solid waste department to find out about curb-side recycling or drop-off centers in your area.

Composting and Alternative Disposal Methods

Instead of burning food scraps, leaves, and yard waste, start a compost pile to turn waste into mulch. You can also use old pallets to create a compost bin. Consider chipping brush to make decorative landscape material or mulch. Find alternative ways to dispose of yard waste, such as licensed landfills, rather than burning it.

Choose Cleaner Alternatives for Warmth and Cooking

If you use a fire pit or outdoor fireplace for warmth or cooking, consider switching to natural gas or propane, which produce fewer harmful air pollutants. Kits are available to convert existing fire rings and pits to natural gas or propane burners.

Check Local Laws and Air Quality Alerts

Be aware of any local ordinances that restrict backyard recreational fires. Some areas may have burn bans due to adverse weather conditions like drought and high winds. Avoid burning wood during air quality alert days when pollution levels are already high. Take extra care if you live in an area prone to brush fires.

By following these steps, you can help reduce biogenic pollutants and create a cleaner, healthier environment for yourself and your community.
