| apparent bioaccumulation of cylindrospermopsin and paralytic shellfish toxins by finfish in lake catemaco (veracruz, mexico). | compared to the well-characterized health threats associated with contamination of fish and shellfish by algal toxins in marine fisheries, the toxicological relevance of the bioaccumulation of toxins from cyanobacteria (blue-green algae), as the primary toxigenic algae in freshwater systems, remains relatively unknown. lake catemaco (veracruz, mexico) is a small, tropical lake system specifically characterized by a year-round dominance of the known toxigenic cyanobacterial genus, cylindrospermop ... | 2011 | 21838624 |
| first evidence of "paralytic shellfish toxins" and cylindrospermopsin in a mexican freshwater system, lago catemaco, and apparent bioaccumulation of the toxins in "tegogolo" snails (pomacea patula catemacensis). | exposure to cyanobacterial toxins in freshwater systems, including both direct (e.g., drinking water) and indirect (e.g., bioaccumulation in food webs) routes, is emerging as a potentially significant threat to human health. we investigated cyanobacterial toxins, specifically cylindrospermopsin (cyn), the microcystins (mcyst) and the "paralytic shellfish toxins" (pst), in lago catemaco (veracruz, mexico). lago catemaco is a tropical lake dominated by cylindrospermopsis, specifically identified a ... | 2010 | 19651152 |
