Fertility preservation in testicular cancer – predictors of spermatogenesis
24 ScepticalFrench Isn't there a risk of overestimation via the fact that mussels are filter-feeders and hence are more likely to accumulate more easily molecules such as plastics or heavy metals ? And the fact that sea food is not necessarily representative of our diet ? I'm genuinely asking, I have no idea.

4 Lukimcsod "Potentially dangerous" What does this mean here? I always assumed these particles were non digestible and simply passed through the body or did relatively little. The term "potentially" seems to imply we don't know if they are or not yet. Which then begs the question why OP is calling them potentially dangerous?
5 mvea The title of the post is a copy and paste from the subtitle and fourth paragraph of the linked academic press release here: > We could be swallowing more than 100 tiny plastic particles with every main meal, a Heriot-Watt study has revealed. > The scientists, from Heriot-Watt University concluded that the average person swallows up to 68,415 potentially dangerous plastic fibres a year simply through sitting down to eat. Journal reference: Ana I. Catarino, Valeria Macchia, William G. Sanderson, Richard C. Thompson, Theodore B. Henry, Low levels of microplastics (MP) in wild mussels indicate that MP ingestion by humans is minimal compared to exposure via household fibres fallout during a meal, Environmental Pollution, Volume 237, 2018, Pages 675-684, ISSN 0269-7491, DOI: https://doi.org/10.1016/j.envpol.2018.02.069. Link: http://www.sciencedirect.com/science/article/pii/S0269749117344445 Highlights • First field assessment of microplastics (MPs) using caged deployed mussels (Mytilus edulis). • First report of the presence of MPs in the protected mussel species Modiolus modiolus. • There is an allometric relationship between the number of MPs and the mussels wet weight. • The potential for human ingestion of fibres resulting from household dust is higher than the ingestion of fibres via mussel consumption. Abstract > Microplastics (MPs) are the most numerous debris reported in marine environments and assessment of the amounts of MPs that accumulate in wild organisms is necessary for risk assessment. Our objective was to assess MP contamination in mussels collected around the coast of Scotland (UK) to identify characteristics of MPs and to evaluate risk of human exposure to MPs via ingestion of mussels. We deployed caged mussels (Mytilus edulis) in an urbanised estuary (Edinburgh, UK) to assess seasonal changes in plastic pollution, and collected mussels (Mytilus spp and subtidal Modiolus modiolus) from eight sampling stations around Scotland to enumerate MP types at different locations. We determined the potential exposure of humans to household dust fibres during a meal to compare with amounts of MPs present in edible mussels. The mean number of MPs in M. modiolus was 0.086 ± 0.031 (SE, n = 6)/g ww (3.5 ± 1.29 (SE) per mussel). In Mytilus spp, the mean number of MPs/g ww was 3.0 ± 0.9 (SE, n = 36) (3.2 ± 0.52 (SE) per mussel), but weight dependent. The visual accuracy of plastic fibres identification was estimated to be between 48 and 50%, using Nile Red staining and FT-IR methodologies, respectively, halving the observed amounts of MPs in wild mussels. We observed an allometric relationship between the number of MPs and the mussels wet weight. Our predictions of MPs ingestion by humans via consumption of mussels is 123 MP particles/y/capita in the UK and can go up to 4620 particles/y/capita in countries with a higher shellfish consumption. By comparison, the risk of plastic ingestion via mussel consumption is minimal when compared to fibre exposure during a meal via dust fallout in a household (13,731–68,415 particles/Y/capita).
2 welterought What does cooking do to these fibers?
1 Longtton Idk about this "fact".. I believed the swallowing spiders in your sleep thing for years.
1 i_am_archimedes good thing plastic is organic
0 cornrichard Don't forget about the spiders that you accidentally ingest while you sleep. They can be loaded with plastic also.
