Formula
Daily = (Seafood x 15) + (Bottled L x 94) + (Tap L x 5.5) + (Salt g x 0.6) + (Shellfish x 90)
Particle counts from research averages: seafood 15/serving, bottled water 94/L, tap 5.5/L, sea salt 0.6/g, shellfish 90/serving.
Worked Examples
Example 1: High Bottled Water Consumer
Problem:2 seafood/day, 3L bottled, 0L tap, 6g salt, 2 shellfish/day.
Solution:Seafood=30\nBottled=282\nTap=0\nSalt=3.6\nShellfish=180\nDaily=496
Result:496 particles/day | 3469/week (High)
Example 2: Filtered Tap Consumer
Problem:1 seafood/day, 0L bottled, 2.5L tap, 4g salt, 0 shellfish.
Solution:Seafood=15\nBottled=0\nTap=14\nSalt=2.4\nShellfish=0\nDaily=31
Result:31 particles/day | 218/week (Low)
Frequently Asked Questions
What are the health risks of microplastic ingestion?
Research shows microplastics can cross the gut barrier entering the bloodstream with particles detected in human blood lung tissue placenta and breast milk. Plastics carry adsorbed pollutants including phthalates bisphenols and persistent organic pollutants that may leach into tissues. Nanoplastics penetrate cell membranes potentially causing inflammation oxidative stress and cellular damage. Definitive health impacts at current exposure levels remain under active research.
What can individuals do to reduce microplastic exposure?
Switch from bottled to filtered tap water using reverse osmosis or quality carbon filter to eliminate the largest source. Reduce shellfish consumption or source from cleaner waters. Use glass or stainless steel food containers especially for heating since microwaving plastic dramatically increases particle release. Choose natural fiber clothing to reduce laundry microfiber shedding. Install a laundry microfiber filter. Minimize highly processed foods contacting plastic packaging.
