微塑料密度计算器
使用微塑料密度计算器评估水体或土壤中微塑料的污染浓度。输入采样数据，计算每升或每千克中的微塑料颗粒密度，监测和评估微塑料污染严重程度。

Microplastic Concentration vs Particles Found in Sample
公式
Microplastic Contamination in Water
Microplastics are plastic fragments smaller than 5 mm found in oceans, rivers, drinking water, and even the air.
Formula
Concentration (particles/L) = Particle Count / Sample Volume (L)
Daily Intake = Concentration x Daily Water Consumption
Studies have found 0-60 particles per liter in tap water and up to 300+ particles per liter in bottled water. The health effects of microplastic ingestion are still being researched.
计算示例
A 1-liter water sample contains 50 microplastic particles. You drink 2 liters per day.
- 01Concentration = 50 / 1 = 50 particles/liter
- 02Daily intake = 50 x 2 = 100 particles/day
- 03Annual intake = 100 x 365 = 36,500 particles/year
常见问题
Where do microplastics come from?
Major sources include synthetic clothing fibers (laundry), tire wear, plastic packaging breakdown, cosmetic microbeads, and industrial processes.
Is bottled water safer than tap?
Studies generally find more microplastics in bottled water than tap water, likely from the plastic bottle itself and the bottling process.
What health effects do microplastics have?
Research is ongoing. Potential concerns include inflammation, cellular damage, and acting as carriers for harmful chemicals. The WHO considers current levels low-risk but calls for more research.
