Dry and Wet Atmospheric Deposition Composition in Southwest Florida: Environmental and Health Implications

Southwest Florida is one of the most rapidly growing regions United States and has been impacted over past decade with water-quality issues some associated health problems. The ionic ratios dust measured in southwest vary significantly from those on east coast Caribbean. metals concentrations reported herein are enriched potassium calcium local sources. Atmospheric deposition nutrients appears to have potential impacts both indirect problems environmental concern, particularly harmful algal blooms. However, no significant research performed measurement concentration either including micronutrient iron or nutrient occurring atmospheric dry wet fallout Florida. Measurements composition key were made a one-year period. Concentrations total phosphorus ranged 0–80.5 mg/kg an average 4 rainfall 1–15.8 чg/L mg/kg. Nitrate 0–746 114.4 soluble form, 1.3 718 209.9 insoluble form. Ammonia was range 1.4 658 101.4 rainfall. Iron found at ranging 0–81 3.8 0–125.7 3.0 While not likely initiate bloom, they sustain existing bloom. Global climate change may exacerbate aerosol issue by increased wind speeds Africa longer term drought conditions caused temperature increases.
