Environmental groups warn against releasing balloons

Environmental groups warn against releasing balloons

MANATEE COUNTY – What goes up must come down, but in the release of celebratory helium-filled balloons, it’s the coming down that creates problems.

In addition to adding trash to the waters, deflated balloons can cause marine life to become entangled and die. The balloons also can be ingested by marine life.

In May, researchers from the Sarasota Dolphin Research Program (SDRP) spent five days offshore conducting dolphin research, but they found more than dolphins.

“We collected 76 balloons and other marine debris up to dozens of miles offshore, including two ghost crab trap lines with floats and a beach ball. Most of the balloons had Mother’s Day or birthday messages,” according to the SDRP website.

Mylar balloons are made of synthetic nylon with a metallic coating, are non-biodegradable and can travel long distances.

“They heavily contribute to oceanic waste and animals can become entangled in them or ill from ingesting whole balloons or pieces,” according to the SDRP. “Wayward balloons are also extra dangerous for sea turtles because they resemble jellyfish – one of turtles’ common prey items.”

The Florida Fish and Wildlife Conservation Commission (FWC) also warns against the release of balloons as being hazardous to marine life.

“Marine and coastal wildlife can become entangled or trapped in many items such as fishing line, crab traps, balloons with attached string, beach furniture and other types of marine debris. In addition, some of these items may be ingested, leading to further harm,” according to the FWC website. “Monofilament fishing line and other plastics (bags, deflated balloons, etc.) can drift into seagrass beds or snag onto floating vegetation – a sure path to a slow death if a manatee ingests any of these items and is not able to pass it through its digestive system.”

Florida Statute 379.23 prohibits the release of more than 10 balloons within 24 hours. Violation of the law can result in a $250 fine.

Piney Point pollution spreading, affecting dolphins

Piney Point pollution spreading, affecting dolphins

TAMPA BAY – The Sarasota Dolphin Research Program at Mote Marine is monitoring the dolphin community near Port Manatee for impacts from the April discharge of 215 million gallons of polluted water from the Piney Point phosphate plant into Tampa Bay last month.

The water was released from one of the closed plant’s gyp stack retention ponds to take pressure off the compromised stack, avoiding its collapse and a potentially worse spill of its contents. It is an acidic blend of saltwater and debris from a Port Manatee dredge project, stormwater runoff, rainfall and “legacy process water” – wastewater from phosphate processing that contains nutrients such as phosphorus and nitrogen, which feed toxic algae blooms.

The plant is in an environmentally sensitive area, near aquatic preserves at Bishop Harbor and Terra Ceia Bay.

Since April 5, four days before the discharge ended, scientists have conducted photographic identification surveys to determine which resident dolphins are being exposed to the highest concentrations of discharged waters, whether they are moving away from the discharges and whether they are having respiratory issues, exhibiting abnormal behavior or developing unusual skin conditions.

Preliminary indications are that fewer dolphins are using the waters near Port Manatee and are mostly congregating more than two miles away from the discharge site. Scientists have identified two dolphins known to the program since 1990, and another first identified in 2009.

The program, which works with the Chicago Zoological Society, has been studying the dolphin communities along Florida’s central and southwest coast since 1970.
