Research indicates bumblebees collect pollen with significantly higher concentrations of toxic metals like arsenic and lead compared to honeybees, even when foraging in the same areas. This suggests honeybees alone may not be reliable indicators of environmental pollution for all pollinator species.
Debris from the demolition of the White House East Wing that was dumped at a nearby public golf course has tested positive for lead, chromium and other toxic metals, the National Park Service said. An interim report by a Virginia engineering firm says the toxic metals, along with PCBs, pesticides, petroleum by-products and other chemicals were detected at levels above laboratory reporting limits in soil at the East Potomac Golf Links, a historic golf course that US President Donald Trump plans...
Scientists at Mount Sinai used lasers to analyze baby teeth from 500 children in Mexico City, creating a week-by-week timeline of metal exposure from the womb through early infancy. By pairing this with MRI brain scans and behavioral assessments in adolescence, they found that exposure to metals like lead, manganese and copper during the critical 6-9 month developmental window was strongly linked to reduced brain volume, abnormal white matter, and behavioral issues including inattention and hyperactivity. The study reveals timing of exposure matters as much as dosage.
