Toxic chemicals in toys can pose health risks to children. Common harmful substances include phthalates, which are used to make plastics more flexible, and lead, a heavy metal that can cause serious health issues. These chemicals can be found in items like plastic toys, paint, and dolls, potentially leading to exposure through ingestion or skin contact. Regulatory agencies, such as the Consumer Product Safety Commission (CPSC), monitor and set safety standards for toys. Many countries have banned or limited the use of certain toxic chemicals in children's products to ensure safer play environments. Parents are encouraged to check for safety certifications when purchasing toys.
