How does air pollution impact plant growth?
How does air pollution impact plant growth?
Air pollution hinders the accumulation of resources, which has a detrimental effect on plant growth.
What is the effect of air pollution on plant resource allocation?
What is the effect of air pollution on plant resource allocation?
The allocation of resources to plant structures varies due to decreased resource capture, including carbohydrate generation, mineral nutrient intake, and water uptake.

Study Notes
Air Pollution
- Air pollution hinders plant growth by interfering with net carbon fixation and metabolic function of leaves.
- O3 and NOx are air pollutants that obstruct plant growth.
- Heavy metals and other air pollutants deposited on soil hurt root development and prevent plants from utilizing soil resources.
- Air pollution alters resource allocation in plants, affecting carbohydrate generation, mineral nutrient intake, and water uptake.
Acid Mine Drainage
- Acid mine drainage is a critical environmental impact of mining.
- Sub-surface mining requires constant pumping to avoid flooding, which stops when the mine is closed.
- Mining generates contaminated wastewater, which can be disposed of through undersea tailings, land storage, or refilling the mine.
- Disposal of wastewater can destroy nearby flora and pose health risks to the local population.
- Acid mine drainage can be 20 to 300 times more acidic than acid rain, killing fish and aquatic species, and burning human skin.
Pollution by Heavy Metals
- Heavy metals are natural elements with high atomic weight and density at least five times greater than water.
- Pollution by heavy metals is a significant environmental impact of mining.
- Heavy metals can leach from ore and waste rock, contaminating water and posing health risks.
Environmental Impact
- Mining operations can alter the competitive dynamics within an ecosystem, modifying the composition of the local plant community.
- Environmental damage in mining practices can be reduced by enforcing federal and state laws, and using non-toxic extraction techniques like bioleaching.
