Had fun in the sun on the climb zone today at Bike/Ski Wentworth.
Also pleased to be able to see our cottage from the trail (if you look carefully).

➡️ #Microplastics were predominantly in the 2–10 μm and 10–20 μm size ranges in #mussels and #oysters, respectively.
➡️ In sites where mussels and oysters were co-located, concentrations of #microplastics were significantly higher in mussels suggesting physiological or anatomical differences which may influence #microplastic uptake and accumulation.

➡️ In sites where mussels and oysters were co-located, concentrations of #microplastics were significantly higher in mussels suggesting physiological or anatomical differences which may influence #microplastic uptake and accumulation.
➡️ Bivalves were collected from 13 locations across #NovaScotia.
➡️ Mean #microplastics concentrations were 4 particles per gram wet weight tissue (or 49 particles per individual) in #mussels, and just under 4 particles per gram wet weight tissue (or 53 particles per individual) in #oysters.
