Cyanobacterial blooms are increasingly common in aquatic environments, raising concerns about the health impacts associated with toxins they produce. One of these is β-methylamino-L-alanine (BMAA), a neurotoxin linked to neurodegenerative diseases. Monitoring BMAA levels environment challenging due trace concentrations and complex matrices, new approaches needed for assessing exposure risk. In this laboratory study, Australian freshwater mussels, Velesunio ambiguus, were exposed BMAA-producing cyanobacterium, Microcystis aeruginosa, assess its accumulation toxin over time. A sample preparation analysis method was developed allow accurate quantification mussels at as low 0.4 ng/g. Mussels M. aeruginosa accumulated BMAA, increasing period. Rapid depuration occurred after cyanobacterium ended, quickly returning pre-exposure levels. These results demonstrate potential be used bioindicators field monitoring time, where rapid unlikely.

The Great Salt Lake (Utah, USA) is reducing in size, which raises several ecological concerns, including the effect of an increasing area dry playa exposed by retreating lake. This study focuses solely on concerns about toxicity metals dust blowing off playa. Although considerable efforts have been made to understand aeolian urban areas along Wasatch Front, located just east and south Lake, there still a need consolidate existing research conduct compositional analysis found these areas. We investigated reaching monitoring sites around that are managed Utah Division Air Quality. By analyzing historical data, we decrease Lake's surface has not led statistically significant increase events Windrose plots align with prior research, indicating heightened levels coincide winds originating from or west, passing over identified playas deserts such as Milford Flats, Sevier Dry Tule Desert, Dugway Proving Grounds, West Desert Utah. Metallic was used evaluate potential health risks associated using hazard quotient, air regional screening levels, cancer risk methods. revealed no concentrations toxic metals. However, this preclude dust-related especially due pre-existing arsenic lead levels.
