Everyday smoke and grilling are major sources of toxic pollutants

Phytoremediation

If you garden near a busy road, use a wood-burning fire pit, or grill often, the soil in your beds may be picking up the same carcinogenic compounds this review traces back to everyday combustion.

Scientists pulled together ten years of studies on polycyclic aromatic hydrocarbons, a family of pollutants that form whenever something burns incompletely, like a car engine, a barbecue, a cigarette, or a wood fire. These compounds settle into soil, water and air and can cause cancer and birth defects over time. The good news is that certain bacteria, fungi and enzymes can break these pollutants down, offering a natural cleanup path for contaminated ground.

Key Findings

1

PAHs mostly come from incomplete combustion of petroleum, oil, coal and wood, with only a small share from natural sources like volcanoes and forest fires

2

The review covers roughly a decade of published research on PAH sources tied to daily human activities such as cooking, smoking, heating and transportation

3

Enzymes, bacteria and fungi are highlighted as practical degradation tools for breaking down PAHs already present in contaminated environments

chevron_right Technical Summary

This review rounds up a decade of research on where cancer-causing PAH pollutants come from in daily life, from car exhaust and grilling to wood stoves and cigarette smoke, and looks at ways bacteria, fungi and enzymes can help break them down in contaminated soil and water.

Original paper

A short review on polycyclic aromatic hydrocarbons (PAHs) emission from common daily living activities.

Polycyclic aromatic hydrocarbons (PAHs) are molecules of great interest because of their carcinogenic, teratogenic and toxic properties. The presence and distribution of PAHs in the environment is ...

Soil health is the capacity of soil to function as a living ecosystem, supporting complex interactions between microorganisms, soil fauna, and plant communities. For plant science, soil health is critical because these biological and chemical soil properties directly control nutrient availability,
