Rational Design, Synthesis, and Characterization of a Solid Δ9-Tetrahydrocannabinol Nanoformulation Suitable for "Microdosing" Applications.

This article highlights the formulation of a solid Δ-tetrahydrocannabinol (THC)-loaded ingestible prepared from pure THC distillate. A THC-containing ethanol-assisted cannabinoid nanoemulsion (EACNE) was created using a solvent displacement technique. Subsequently, the EACNE was converted to a solid powdery material while still retaining its THC potency, a format uniquely suited for "microdosing" applications.

Polybrominated Diphenyl Ethers (PBDEs) in Marine Fish and Dietary Exposure in Newfoundland.

Presence of PBDEs tested in 127 liver samples from Atlantic Cod (Gadus morhua) and Turbot (Scophthalmus Maximus) and 80 adult participants from two rural Newfoundland communities. Seafood consumption was measured through a validated seafood consumption questionnaire. PBDEs (-28, -47, -99, -156, and -209) were found in all fish liver samples, and PBB-153 and PBDEs-28, -47, -99, -100, -153 were identified as the most prominent congeners from the participants' serum samples.

Do zebra mussels (Dreissena polymorpha) alter lake water chemistry in a way that favours Microcystis growth?

This study examined possible relationships between the presence of zebra mussels (Dreissena polymorpha) and Microcystis spp. abundance. Experiments were conducted in 12 microcosms designed to mimic shallow lake ecosystems.
