A Senior Research Scientist at the CSIR-Water Research Institute, Dr Pennante Naa Ayikailey Bruce-Vanderpuije, has raised concerns over the environmental and public health risks posed by refuse dumped at the McCarthy Down landfill site. According to her, plastics found in the waste contain harmful chemicals such as phthalates and bisphenol A (BPA), which can pose serious health risks to humans when they leach into the environment.
