3、Spatial and temporal distribution characteristics and prediction

The aim of this study was to explore the characteristics of non-point source pollution of nitrogen (N) and phosphorus (P) under the background of climate and land use in Shandong Province.

4、How nitrogen compounds in fertilizers and fossil

Human activities have led to high levels of nitrogen compounds entering the environment, causing air and ecosystem pollution.

What Is Nitrogen Pollution? – The Institute for Environmental Research

Nitrogen pollution is the contamination of the environment – air, water, and soil – with excessive amounts of reactive nitrogen compounds, largely resulting from human activities such as agricultural fertilization and fossil fuel combustion.

Evolution Characteristics and Control Suggestions for

The characteristics of agricultural non-point source pollution presents as follows: chemical oxygen demand (COD) emissions have become the most significant pollutant, accounting for 90% of the total pollution; livestock and poultry breeding has become the main source of pollution; and the key areas of pollution have shifted from the lower ...

The characteristics of nitrogen and phosphorus output in China's highly

The nitrogen (N) and phosphorus (P) transportation due to the anthropogenic activities have strong correlations to the water pollution events. In the highly urbanized Pearl River Delta (PRD) region of China, the main input pathways for N and P have been changed.

Environmental impacts of nitrogen emissions in China and the role of

Atmospheric reactive nitrogen (N r) has been a cause of serious environmental pollution in China. Historically, China used too little N r in its agriculture to feed its population.

The nitrogen fertilizer industry is an indispensable part of agricultural production, playing a crucial role in enhancing crop yields and improving soil quality. the production and use of nitrogen fertilizers generate characteristic pollutants that pose significant threats to the environment and human health. The following are the key characteristics of these pollutants:

1. Nitrogen Gas (N₂): During nitrogen fertilizer production, raw materials such as ammonia or urea react with oxygen in the air, producing nitrogen oxides (NOₓ) and nitric oxide (NO). These compounds harm human health, causing respiratory issues and eye irritation. Additionally, nitrogen gas itself is a greenhouse gas, contributing to global warming.

2. Ammonia (NH₃): A common byproduct of nitrogen fertilizer production, ammonia is toxic to humans. Excessive inhalation can lead to respiratory distress, coughing, and throat pain. Prolonged exposure to high concentrations may damage the nervous system and liver. Ammonia also acts as a greenhouse gas.

3. Volatile Organic Compounds (VOCs): Solvents and catalysts used in production may release VOCs, which easily evaporate under high temperatures and pressures. These compounds degrade air quality and can harm the respiratory and nervous systems when inhaled over long periods.

4. Heavy Metals: Some raw materials contain heavy metals like lead, cadmium, and mercury. These metals contaminate water and soil through industrial waste, leading to long-term health risks such as poisoning and neurological damage.

5. Pesticide Residues: Raw materials or additives may carry pesticide residues that persist in soil, affecting crop growth and quality. These residues can also enter the food chain, posing health hazards.

6. Microbial Contamination: Equipment and pipelines may harbor microbial growth, leading to contamination that risks foodborne illnesses and infectious diseases.

Pollution Control Measures:

1. Source Control: Implement strict controls on raw materials, production processes, and waste treatment. Prioritize eco-friendly materials, optimize manufacturing to reduce harmful outputs, and ensure wastewater meets discharge standards.

2. Environmental Awareness: Train industry personnel on sustainability and encourage adoption of green technologies.

3. Regulatory Enforcement: Governments should strengthen oversight, conduct regular environmental assessments, and penalize non-compliant enterprises.

4. Green Production: Incentivize energy-efficient and low-emission practices through policies and subsidies.

5. Research Advancements: Invest in pollution-reduction technologies and foster collaboration between enterprises and research institutions.

the nitrogen fertilizer industry’s characteristic pollutants—including nitrogen gas, ammonia, VOCs, heavy metals, pesticide residues, and microbes—require targeted mitigation strategies to safeguard environmental and public health.
