Researchers found that urban wildflowers, intended to help struggling bee populations, are absorbing toxic metals from contaminated soils, specifically in Cleveland, Ohio. Common plants like chicory and clover accumulate harmful levels of lead, arsenic, and cadmium, which impair bee health and contribute to their decline. Soil pollution from industrial activities poses a significant risk to pollinators, thwarting conservation efforts. The study emphasizes the need for soil testing and remediation before planting to protect these vital species from further harm.
Before planting wildflowers in urban areas to attract bees and other pollinators, it's important to consider the history of the land and what might be in the soil.
This research shows that wildflowers on former industrial sites absorb metals from contaminated soil, turning what should be a lifeline into a toxic trap for bees.
