Abstract Effluent discharges can potentially result in high concentrations of metals entering aquatic environments for short durations, ranging from a few hours to days. The environmental risks of such exposures are challenging to accurately assess. Risk assessment tools for effluent discharges include comparison of toxicant concentrations with guideline values and the use of direct toxicity assessments, both of which were designed to assess continuous, rather than pulse, contaminant exposures. In this study, a chronic pulse-exposure toxicity test was developed using the tropical euryhaline calanoid copepod Acartia sinjiensis. This copepod has a rapid life cycle and is highly sensitive to metal contaminants, with 50% effect concentrations (chronic EC50) for larval development of 1.7, 8.6 and 0.7 μg L for copper, nickel and zinc, respectively. The toxicities of copper and nickel were assessed as a continuous exposure (78 h) and as pulses (3, 6 and 18 h) initiated at varying l ....
Microplastics in seafood are most likely to come via oysters, mussels and shellfish. But how much of a health risk do they pose? Posted MonMonday 8 updated MonMonday 8 MarMarch 2021 at 9:11pm Bivalves like oysters and mussels are most likely to contribute microplastics to our diet because we eat them whole. ( Print text only Cancel Key points: Australians are most likely to eat microplastics in bivalves like mussels and oysters The main type seafood eaten by Australians is fish fillet, which is a low risk for microplastics We still don t know what effect, if any, microplastics have on human health Microplastics abound in the ocean and are often eaten by sea creatures, which means the particles could also make their way into our bodies when we consume seafood. ....
A plate of four 7-ounce stone crab claws at a restaurant can cost you $140. They re partly pricey due to how they re caught, which is can be exhaustive and sometimes dangerous. Following is a transcript of the video. Narrator: Stone crab claws are one of the priciest seafoods you can buy. And depending on their size, a pound of claws at a restaurant can cost as much as $70. But catching these crabs is hard work. Strangely enough, fishers can only harvest the claws from the crabs, while the bodies must be returned to the ocean. So, what makes these claws so coveted? And why are they so expensive? ....
Lobsterman Catches Ultra-Rare Yellow Lobster, Dubbed ‘Banana,’ Deemed 1 in 30 Million Catch An extraordinary ocean discovery has spurred scientific inquiry after a lobsterman caught a yellow-hued lobster with a genetic mutation so rare, it only affects 1 in every 30 million lobsters. Upon catching the rare crustacean, lobsterman Marley Babb donated it to the University of New England’s Marine Science Center in Biddeford. The lobster was affectionately named “Banana,” after its striking coloration. A rare yellow lobster has been caught off the coast of Maine and has been lovingly named “Banana.” (Courtesy of University of New England) “After working Wednesday, Marley insisted on driving Banana all the way down from Tenant’s Harbor to drop her off,” Lindsay Forette, lab coordinator and chemical hygiene officer at the marine center, said in a statement on Feb. 5. ....
