Toxic Components of Plastic Pose Carcinogenic Threat to Public Health
AI summary Read the abstract
A wide range of toxic and carcinogenic chemicals — including bisphenol A, phthalates, brominated flame retardants, and polychlorinated biphenyls — are incorporated into common plastic products and can leach out during use. This review argues that chronic low-level exposure to these plastic-associated chemicals poses serious genotoxic and cancer risks to humans, and calls for greater public awareness and investment in safer biodegradable alternatives.
The toxicity of plastics and its components is increasing day by day for human needs. In modern days, plastics are widely used in every product in our daily life. In 2021, it was predicted that the world would produce 390.7 million metric tons of plastic. A year's worth of plastic waste is produced in India at 3.4 million tons. Many products are manufactured with plastic due to its impressive characteristics such as inert, flexibility, durability, versatility, lightweight, and less costly. They encourage dangers to the planet and human health. Numerous chemical and toxic contaminants, including Bisphenol A (BPA), phthalates, antimonitroxide, brominated flame retardants, poly-fluorinated chemicals, nonylphenol, polychlorinated biphenylethers, dichlorodiphenyldichloroethylene, phenanthrene, among others, are found in plastics and pose a major risk to human health and the environment. These chemical and hazardous compounds are used in the manufacturing of plastic bottles, containers, pharmaceuticals, food packaging, baby toys, etc. The impact of plastics on the environment gets more dangerous day by day. Not only the environment but also exposure to plastics leads to various human health risks. Toxic components of plastics lead to several serious cancers even;they are also possessing their genotoxic effects on human health. This review contains the toxicity of plastic components on human health and the environment by low-level exposure and gives a proper awareness about the health problems and focuses on degrading ways to reduce its effects.

Environmental and health hazards of chemicals in plastic polymers and products
AI summary Read the abstract
Researchers reviewed the environmental and health hazards of chemicals in plastic polymers and products, examining the toxicological profiles of monomers, additives, and degradation products that can leach from plastics into food, water, and the environment. The study identifies numerous plastic-associated chemicals with endocrine-disrupting, carcinogenic, or developmental toxicity potential and calls for more comprehensive safety testing of plastic formulations.
Micro(nano)plastics pollution and human health: How plastics can induce carcinogenesis to humans?
AI summary Read the abstract
This review examines how microplastics and nanoplastics enter the human body through food, water, and air, and how they may contribute to cancer development. Common plastic types like polystyrene and PVC, along with toxic chemicals they carry such as PAHs and PCBs, have been linked to DNA damage, oxidative stress, and inflammation, all of which can promote cancer. The paper highlights that while the evidence is growing, more research is needed to understand the full cancer risk from chronic microplastic exposure.
