Soil Safety Skepticism

This research investigates the environmental impacts of sharps waste (SW) disposal methods in South Florida (SF) and explores the potential of microneedles (MNs) as a sustainable alternative for Type 1 Diabetes (T1D) patients. Soil samples from a state park (control) and three incineration facilities (Fort Pierce, Fort Lauderdale, and Miami) were analyzed for heavy metal (HM) concentrations, including Chromium, Cadmium, Copper, Lead, Mercury, and Arsenic. The samples underwent chemical analysis at Eurofins Laboratory to determine HM concentrations (mg/kg) and pH levels. The findings revealed elevated levels of Copper, Lead, and Chromium in observational sites compared to the control, with Miami demonstrating the highest concentrations. Lead and Copper concentrations in Miami exceeded Florida’s Residential Exposure (RE) limits, while Cadmium surpassed groundwater leachability thresholds, highlighting potential risks to human health and the environment. Despite small sample sizes limiting statistical significance, the study emphasizes the urgent need to address SW disposal’s environmental consequences. MNs were identified as a promising alternative to reduce medical waste and its associated environmental hazards. This research advocates for the adoption of MNs to mitigate heavy metal contamination, enhance public health, and promote sustainable healthcare practices.
