After a two-week study of the dolphin population in the Indian River Lagoon near the St. Lucie River, scientists found them developing mysterious skin sores and fungal infections.
They also are subject to hepatitis, central nervous disorders and stranding. More than 30% of the marine mammals have a skin disease man-made chemicals and pathogens weaken dolphin's immune systems.
Excess of nitrogen and phosphorus from fertilizers and septic tanks feed algae that emit toxins dolphins ingest and breathe. Pesticides are known for disrupting hormones in dolphins, fish and humans, dampening their reproductive health.
In the northern lagoon, dolphins look healthier. Dolphin's studies are
an indicator of the general lagoon's health. It can also provide warnings of hazards to human health. A similar study will be conducted in Charleston, S.C comparing the two populations.
