„Vârful aisbergului”: mii de zone cu risc de contaminare chimică, în atenția experților din Marea Britanie

An investigation into historical chemical contamination in Wales highlights the extent of an environmental issue. Approximately 20,000 sites in the UK are deemed concerning. Former Monsanto employee Stephen Constance shared his experiences with toxic waste management, raising concerns about inadequate safety measures. The investigation focuses on polychlorinated biphenyls (PCBs), banned in the UK since the 1970s. Despite evidence of contamination, Welsh authorities claim no increased cancer risk has been established. A 2015 inventory identified over 9,000 sites needing further investigation, prompting plans for a comprehensive strategy for the remediation of post-industrial land in Wales.
