In general, long-term excessive P application exerted a remarkable and differentiated impact on the soil P fractions. An increase in the Sol-P and Al-P fractions could lead to enhanced P bioavailability and environmental risk in acidic red soils.

4、Excessive application of chemical fertilizer and organophosphorus

Liu, L., Zheng, X., Wei, X. et al. Excessive application of chemical fertilizer and organophosphorus pesticides induced total phosphorus loss from planting causing surface water eutrophication.

5、Phosphates In Fertilizers: Environmental Impacts And Sustainable

When excess phosphates from fertilizers runoff into nearby water bodies, they contribute to eutrophication, a process where nutrient overload stimulates rapid algae growth, leading to oxygen depletion and the creation of dead zones that harm aquatic ecosystems.

Environmental impact assessment of phosphate fertilizers and

Anthropogenic activity especially usage of phosphate fertilizers and phosphogypsum waste (a by-product of phosphate ore processing into fertilizer) in agriculture field significantly increases the radioactivity level of cultivated soil compared to soil of barren land [1].

6 major hazards of excessive application of phosphate fertilizer to

Excessive application of alkaline phosphate fertilizers such as calcium magnesium phosphate fertilizer will make the soil alkaline, reduce the effectiveness of zinc, and affect the absorption of zinc by crops.

JIPC

Langer and Gunther (2001) have reported that alka-line dust deposits from a phosphate fertilizer plant in Germany drastically reduced soil microbial biomass and enzyme activities, which are important param-eters of soil fertility.

Phosphorus Fertilizer's Environmental Impact: Benefits, Risks, And

In conclusion, soil phosphorus accumulation from excessive fertilizer use poses significant risks to soil fertility and environmental health. The buildup reduces nutrient availability, increases erosion, and harms soil biodiversity, creating a cascade of negative effects.

Toxicity Risks of Fertilizers and How to Minimize Them

Excessive use of fertilizers can disrupt the natural nutrient balance in soils. High concentrations of certain elements, like nitrogen or phosphorus, may cause nutrient imbalances that inhibit plant growth or lead to the accumulation of harmful substances such as heavy metals.

The harms of excessive phosphate fertilizer dust are primarily manifested in the following aspects:

1. Environmental Pollution: The production process of phosphate fertilizer generates significant amounts of dust containing harmful substances such as heavy metals and nitrogen oxides. If not properly addressed, these contaminants can spread through air currents, severely degrading air quality. Additionally, rainwater may wash harmful components from the dust into soil, further contaminating groundwater resources.

2. Health Risks to Humans: Hazardous substances in phosphate fertilizer dust pose severe health threats. Prolonged inhalation of contaminated air can weaken immune systems, increasing susceptibility to respiratory diseases, skin conditions, and other illnesses. Direct skin contact with these pollutants may cause dermatological damage or even trigger poisoning incidents.

3. Crop Damage: Harmful substances in phosphate fertilizer dust directly adhere to crops, compromising growth and yield. These contaminants reduce photosynthetic efficiency, lower crop output, and diminish nutritional value. Long-term use of toxic phosphate fertilizers also disrupts soil structure, impairing its aeration and water-retention capacities, which further hinders plant development.

4. Ecological Damage: Toxic components in phosphate fertilizer dust severely harm ecosystems by destroying soil biodiversity and inhibiting microbial survival, thereby destabilizing ecological balance. these pollutants can enter human food chains, posing indirect health risks.

To mitigate the environmental and health impacts of phosphate fertilizer dust, the following measures are recommended:

1. Enhance Environmental Management: Strictly regulate pollutant emissions during phosphate fertilizer production.

2. Strengthen Product Testing: Ensure phosphate fertilizers meet safety and efficacy standards through rigorous monitoring.

3. Promote Eco-Friendly Alternatives: Advocate for slow-release fertilizers, organic fertilizers, and other environmentally safer options to reduce dust generation.

4. Protect Crops: Avoid excessive use of hazardous phosphate fertilizers to safeguard agricultural productivity.

5. Raise Environmental Awareness: Educate the public on pollution prevention and encourage active participation in conservation efforts.

6. Enforce Legal Frameworks: Establish robust environmental laws and impose strict penalties for non-compliance to ensure effective protection mechanisms.
