Pollution significantly impacts photosynthesis and overall plant health, affecting primary producers’ survival and the health of all life on Earth. This middle school science fair project explores the impact of pollution on plant growth, focusing on the effects of soil pollution on green plants. Trace elements, such as nitrogen and sulfur, can negatively affect plant growth and physiology, including those of agricultural interest. Green infrastructures and vegetation barriers can help mitigate air pollution, identifying important plant traits.
The first quantitative meta-analysis on growth-related traits under acid rain across aboveground and belowground is performed. Plastic contamination on soil and plants has received growing attention, as plastic can affect soil water content and interact with the effects of air pollution. The project aims to test how water impurities affect plant growth, starting from seed planting.
Plutants can harm vulnerable plant species’ leaves, stomata, and senescence prematurely, diminish photosynthetic activity, and interfere with membranes. Most plants require a soil substrate to provide water and nutrients, and whether we farm the plants directly or consume animals that feed on them, we don’t eat them.
This science project demonstrates how plants can use carbon dioxide to grow faster and how global warming can affect plant growth. Polluted water can harm plants and affect plant growth, and poor quality water can prevent seed germination and seedling growth. High levels of particulate fallout may result in heavy deposits on leaf surfaces that reduce photosynthetic rates. The experiment tests the impact of air pollution on plant growth starting from seed, specifically the degree of light a plant receives.

Can plants grow in polluted soil?
The study aimed to assess the survival rates, growth, and chlorophyll fluorescence (Fv/Fm) of four hybrid aspen and two European aspen clones cultivated in creosote- and diesel oil-contaminated soil treatments over a two-year and three-month period. The results showed that contaminated soils affected all plants’ survival rates and growth. However, plants grown in creosote-contaminated soil showed a 99 survival rate, while those in diesel-contaminated soil showed a 22-59 survival rate.
Low plant density resulted in a higher survival rate and growth than in the other two density treatments. In contrast, medium- and high-density treatments did not affect plant survival rate and growth to a greater extent, particularly in contaminated soil treatments. The effects of clonal variation on survival rate, growth, and Fv/Fm values were evident in all treatments. The results suggested that hybrid aspen clones 14 and 291, and European aspen clone R3 were suitable candidates for the phytoremediation experiment, as they demonstrated reasonable survival rates, growth, and Fv/Fm values across all treatments.
A superior survival rate for clone 291, height and diameter growth, and stem dry biomass production for clone 14, were observed in all soil treatments. Overall, a reasonable survival rate (~75) and Fv/Fm value (0. 75) for all plants in all treatments indicate European aspen and hybrid aspen have considerable potential for phytoremediation experiments.

What are the factors affecting plant growth experiment?
The experimental design takes into account a multitude of factors that influence plant growth, including seed variety, water availability, soil type, light, temperature, humidity, and other variables. Two variables, namely seed variety and water availability, will be employed in the experimental procedure.
How do contaminants affect plants?
Organic pollutants disrupt plant parts and functions, including membranes, nuclear functions, and uptake functions. These pollutants can induce genotoxic, carcinogenic, xenobiotic, and endogenic effects. Studies have shown that bisphenol A affects microtubule arrays in root meristematic cells of Pisum sativum L, Raman imaging investigates the ultrastructure and composition of plant cell walls in black spruce wood, and studies on the growth, photosynthesis, and antioxidant defense responses of five vegetable crops to phenanthrene stress.
Does pollution affect soil quality?
Healthy soil is crucial for human health, as it supports diverse ecosystems, essential ecological services like pollination, and stores water to prevent floods. It also captures carbon and slows global climate change. However, soil pollution poses a growing threat to human health, resulting in food crop contamination and disease. Soil pollutants can be heavy metals, organic chemicals, biological pathogens, and micro/nanoplastic particles. Deforestation causes soil erosion, liberates sequestered pollutants, and generates airborne dust.
Pollution of air, water, and soil is responsible for at least 9 million deaths annually, with over 60% of pollution-related disease and death due to cardiovascular disease. The European Commission and the EU Action Plan for 2050: A Healthy Planet for All have determined that air, water, and soil pollution must be reduced to levels that cause no harm to human or ecosystem health. This requires creating a toxic-free environment, respecting the concept of a safe operating space for humanity, and sustaining the health of our planet for future generations. This review article summarizes current knowledge of the links between soil health and human health, discussing the more important soil pollutants and their health effects.
How can environment affect plant growth?
Environmental stress can cause plant problems directly or indirectly, weakening plants and increasing susceptibility to disease or insect attacks. Factors affecting plant growth include light, temperature, water, humidity, and nutrition. Understanding these factors can help manipulate plants for increased leaf, flower, or fruit production and diagnose environmental stress-related problems. Light quantity, which refers to the intensity of sunlight, varies with seasons, with the maximum amount in summer and the minimum in winter.
The more sunlight a plant receives, the greater its capacity for photosynthesis, and understanding these factors can help manipulate plants to meet specific needs and diagnose environmental stress-related problems.
What are the 15 effects of air pollution?
Air pollution has long-term health effects, including heart disease, lung cancer, respiratory diseases like emphysema, and damage to organs like nerves, brain, kidneys, liver, and other organs. Some scientists suspect air pollutants cause birth defects.

What are 10 effects of air pollution on plants pdf?
Air pollution, primarily caused by industrialization, urban sprawl, and transport congestion, poses a significant threat to global ecosystems. It leads to reduced photosynthesis and growth, causing 5-8 yield declines for crops. Leaf damage and altered pollen structure also occur, while animals suffer respiratory issues and lung damage. Photosynthesis, the cornerstone of plant life, is hindered by particulate matter, ozone, sulphur dioxide, and nitrogen oxides.
Studies show that a 10 reduction in photosynthesis can lead to a 5-8 decline in crop yield, with nutrient-rich crops like soybeans experiencing significant reductions even in mildly polluted environments. Understanding these ramifications is crucial for mitigation and conservation efforts.
How does air pollution affect human plants?
Long-term air pollution negatively impacts plants and crops, particularly ozone, which damages stomata, tiny pores on the underside of leaves that allow plants to breathe. Between 1980 and 2011, nine billion dollars worth of soybeans and corn were lost in the US due to ozone pollution. Acid rain, lead toxicity, and exposure to nitrogen oxides alter the chemical nature of soil, robbed plants of nutrients needed for growth and survival, impacting agriculture, forests, and grasslands.
Fuel burning releases sulfur and nitrogen oxides into the atmosphere, forming acid rain when sulfur dioxide and nitrogen dioxide mix with water droplets. Acid rain damages vegetation leaves, increases soil and water acidity, and is linked to over 500 deaths annually. It also damages buildings and structures, causing an estimated five billion dollars of property damage each year. Acid rain dissolves mortar between bricks, causes stone foundations to become unstable, and destroys ancient buildings and statues carved from marble and limestone.
What are the five factors affecting plant growth?
The growth of plants is influenced by a number of factors, including light, heat, water, humidity, and nutrition. It is therefore essential to gain an understanding of the impact of these factors on plant development.
Can pollution stunt growth?
Air pollution has the potential to impede linear growth by precipitating recurrent episodes of febrile respiratory illness, which in turn elevates the risk of child stunting.
