Study by scientists at Cardiff University suggests European farmland could be the biggest global reservoir of microplastics

The Cardiff University study suggests that the microplastics could be present as a result of the usage of sewage sludge fertilizer.

The scientists estimate that “between 31,000 and 42,000 tonnes of microplastics (or 86 — 710 trillion microplastic particles) are applied to European soils annually, mirroring the concentration of microplastics found in ocean surface waters.”

The study suggests that the UK has potentially the highest amount of microplastic contamination in its soils, with 500 — 1000 microplastic particles per square meter of agricultural land applied per year, followed by Spain, Portugal and Germany.

Given that vertical farming does not use fertilizers, that clearly takes away the serious potential health risks caused by these dangerous microplastics.
