PHNOM PENH: The Ministry of Environment has raised serious concerns over the widespread use of hazardous chemicals in plastic products, following a global study showing that more than one-quarter of the chemicals used in plastic production pose risks to human health and ecosystems.
The ministry cited the global PlastChem database, recently published and cited by the EU’s Directorate-General for Environment, noting that a total of 16,235 chemical substances are used in plastic production worldwide.
However, researchers have been able to identify and compile detailed information on only 12,658 of the substances, while the remaining chemicals lack sufficient data on their composition and properties.
“Among the chemicals that have been identified, scientists found that approximately one-quarter are classified as hazardous,” said the ministry.
It stated that these substances are widely used in plastic manufacturing and are released into the environment through production, use, recycling and disposal, posing significant threats to both human health and ecological systems.
The ministry noted that many chemicals of concern are still not regulated at the global level.
These substances are present in everyday plastic products and can enter the human body, where they may persist for long periods due to their resistance and durability.
The study further highlighted that plastics release toxic substances throughout their entire life cycle, from manufacturing and consumption to recycling and waste management.
“Chemical compounds, including microplastics, can accumulate in the human body and have been linked to a range of health problems, including reproductive disorders, neurodevelopmental impairments, immune system disruption and metabolic diseases,” it said.
“The reuse and recycling of old plastics were also identified as a growing concern, as the degradation of aged materials can increase the risk of chemical leakage and exposure,” it added.
The findings have reinforced calls for stronger chemical management, greater transparency in plastic production and the promotion of safer alternative materials.
The ministry stressed that simplifying plastic formulations and eliminating toxic substances are critical steps toward achieving a circular and sustainable plastics economy. - The Phnom Penh Post/ANN
