| evidence for psp in mussels in trinidad. | herein we present the first evidence for the presence of paralytic shellfish poison (psp) in trinidadian waters. the toxin was found in a meat extract of the mussel, perna viridis. psp has not previously been demonstrated in the shellfish of caribbean islands. the presence of psp in trinidad is therefore significant in that it presents an opportunity to better understand the dynamics of psp and algal blooms in both a region and island environment not normally associated with psp.p. viridis is no ... | 2001 | 11137550 |
| heavy metals in green mussel (perna viridis) and oysters (crassostrea sp.) from trinidad and venezuela. | heavy metal concentrations were monitored in edible soft tissues of shellfish from trinidad and venezuela. oysters (crassostrea sp.) and the green mussel (perna viridis), which is a recently transplanted species to the caribbean from the far east, were collected at six locations in venezuela and five in trinidad, the latter along the coast line of the gulf of paria. simple and low-cost methods of analysis were optimized and validated using standard reference materials. cadmium, copper, lead, nic ... | 2002 | 11994781 |
| paralytic shellfish poisoning toxins in green mussels (perna viridis) from the gulf of paria, trinidad. | paralytic shellfish poisoning (psp) toxins were determined in green mussels (perna viridis) collected from one collection site in the gulf of paria in trinidad in 1999 and 2000. aqueous extracts of psp were purified by passage through c-18 spe cartridges, oxidized with peroxide and periodate, respectively, then analyzed by hplc with fluorescence detection. this procedure provided rapid and highly sensitive screening of samples for psp toxins. further purification of psp-containing extracts using ... | 2004 | 15500850 |
| heavy metals in sediments, mussels and oysters from trinidad and venezuela. | the gulf of paria is bordered by both trinidad and venezuela, from which various metallic pollutants and other contaminants can originate. the gulf is still a significant source of fish, crabs and shellfish for human consumption to both countries, where concerns over the quality of this marine environment have been long expressed but never properly addressed. in addition, the circulatory current patterns in the gulf ensure that contaminants originating from either country are likely to affect bo ... | 2005 | 17465143 |
