Martin County receives air quality results

Martin County has received the results of the air quality tests it conducted independently. The samples were collected by Enviro Team North America under contract to Martin County in four areas where algae has accumulated in high densities (two residential sites in Rio and North River Shores; two commercial sites in Rio).

The air was tested for hydrogen sulfide, species of algae, toxin levels present, and respirable particles (whether algae could be inhaled). Water quality samples were also collected at two sites (algae species and toxin levels). The report contained the following conclusions:

* Hydrogen Sulfide – Levels were discernible at levels which may be intolerable for individuals with respiratory conditions and asthmatics.
* Water Toxins – Microcystin levels in the algal water samples present a significant health threat upon direct exposure or ingestion. The water results indicate extremely high levels of Microcystin toxins in the accumulated algae areas, reported at 100-1000 times higher than the recreational guidance levels of 10 micrograms/liter.
* Airborne Toxins – Microcystin levels in the air were identified, indicating that toxins can become aerosolized when agitated. It should be noted that there are no set standards for inhalation risk by any federal, state or local regulatory agency. We defer to our public health authorities for inhalation avoidance or inhalation risk concerns.

* Particulates – Measured respirable particle concentrations are within an expected range for an outdoor environment, however, increased particle concentrations measured by water pump discharge associated with algae removal technologies suggest that further study should be performed to determine what impact this may have on human, animal exposure and/or the environment.
* Volatile Organic Compounds- The total volatile organic compounds were not detectable.

Martin County has provided the report to the Florida Department of Environmental Protection and the Florida Department of Health for review, which the agencies have indicated could take several weeks to complete.

Martin County continues to advise it is best for humans and animals to avoid contact with areas where algae is present. We also advise avoidance of sitting downwind of any algae bloom or algae material which is drying onshore, and respecting any water-body closures announced by local public health authorities. If any health effects are subsequently experienced in whatever the nature of the exposure, seek medical advice.
