URI biological oceanographers study potentially toxic microalgae on the northeast coast

The scientific community concurs that the occurrence of harmful algal blooms (HABs) is increasing worldwide. The annual loss from HABs worldwide is probably more than $1 billion, including both mortality and unmarketable products. The annual human cost has been estimated at 2,000 cases of poisoning with 15% mortality. Because there is no international record of economic loss and human intoxication incidents by HABs, these numbers are almost certainly underestimates.

In a recent issue of Northeastern Naturalist, University of Rhode Island biological oceanographers Paul E. Hargraves and Lucie Maranda described the occurrence of 46 phytoplankton species that are potentially toxic to humans, or harmful to marine life, or both. The area from which they compiled their information includes the southeast coast of Nova Scotia to the Hudson River estuary in New York and out to the edge of the continental shelf. The research was supported by the National Science Foundation and the National Oceanic and Atmospheric Administration.

Hargraves and Maranda included in their list species considered potentially toxic to humans if one or more strains of the species is known to produce toxins affecting humans, the species in strongly implicated or proven to cause human illness or fatality, or the species has produced a positive reaction in mammalian toxicity tests. They also included species harmful to marine life if one or more strains are known to produce substances harmful to normal life processes, or the species is strongly implicated or proved to cause mortality under laboratory or natural conditions.

The comprehensive list contained in the article describes each species, its characteristics, location, the level of toxicity, and some of the problems the species has caused to marine plants, animals, and humans.

"We must emphasize that the presence of a species known to be toxic or harmful in other coastal locations does not mean that it is so in our
