Hazards of nitrogen fertilizers and ways to reduce nitrate accumulation

Genetic background, environmental factors such as light circumstances and agronomic variables are three main causes affecting crop plant nitrate accumulation (Santamaria et al. 2001).

The production and use of nitrogen fertilizers are crucial for agricultural development, but they also pose a series of environmental problems and health risks. The following are potential hazards associated with nitrogen fertilizer production:

1. Soil Pollution: Nitrogen in fertilizers is not easily fixed in soil and can be rapidly absorbed by plants, leading to excessive nitrogen content. This causes soil acidification, salinization, disrupts soil structure, and reduces microbial activity and biodiversity, ultimately harming crop growth. Long-term overuse of nitrogen fertilizers may also accumulate heavy metals (e.g., lead, cadmium) and pesticide residues in soil, posing environmental and human health risks.

2. Water Eutrophication: Excessive nitrogen runoff into water bodies leads to eutrophication, which threatens aquatic life, degrades water quality, and causes fish kills. It also contaminates drinking water sources, endangering human health.

3. Air Pollution: Nitrogen fertilizer production releases harmful gases like ammonia (NH₃) and hydrogen sulfide (H₂S), while combustion processes generate pollutants such as sulfur dioxide (SO₂) and nitrogen oxides (NOₓ), exacerbating air quality issues.

4. Greenhouse Gas Emissions: Nitrogen fertilizer production relies heavily on fossil fuels (e.g., coal, oil), emitting CO₂ and methane (CH₄). Additionally, reduced carbon sequestration in farmlands due to fertilizer use further amplifies greenhouse gas emissions.

5. Land Desertification: Nitrogen fertilizers accelerate soil moisture evaporation, reducing water retention capacity. Prolonged overuse leads to salinization, impaired soil permeability, and decreased vegetation, worsening desertification.

6. Groundwater Contamination: Nitrogen runoff increases nitrate levels in groundwater, posing long-term health risks such as neurological or kidney disorders from contaminated drinking water.

7. Ecological Imbalance: Disruption of soil microbial communities and biodiversity affects crop growth and other organisms. Decomposition of nitrogen fertilizers may release toxic substances, harming ecosystems and human health.

8. Food Safety Risks: Excessive nitrogen use raises nitrate levels in crops, which can cause health issues when consumed. Accumulation of heavy metals and other toxins in agricultural products further compromises food safety.

9. Energy Waste: Nitrogen fertilizer production is energy-intensive, relying on electricity, coal, etc., raising agricultural costs and contributing to carbon emissions during manufacturing and transportation.

10. Environmental Pollution: Untreated wastewater, exhaust gases, and solid waste from production and use contaminate air, water, and soil, threatening ecological and human health.

while nitrogen fertilizers support agriculture, their production and application entail significant environmental and health challenges. Strengthened environmental management, improved nitrogen use efficiency, and pollution reduction are critical to safeguarding ecosystems and public health.
