Why Pumpkins Trap Forever Chemicals — and How Hydroponics Helps

Dr. Russell Sharp explores research showing that squashes, pumpkins and other cucurbits can absorb persistent hydrophobic pollutants (PCBs, dioxin-like compounds, organochlorine pesticides and furans) because a specific plant protein binds these chemicals and transports them into the fruit. The episode covers the health and food-safety implications, the potential to breed low-accumulating varieties or use phytoremediation, and why growing these crops hydroponically is a safer alternative to avoid soil-borne, long-lasting pesticides. https://eutrema.co.uk/shop/fertiliser/liquid-gold-unique-complete-fertiliser/ Todd C.
