Toxicants can affect critical windows in various ways:
Disruption of Cellular Processes: Toxicants can interfere with cell division, differentiation, and apoptosis, leading to developmental anomalies. Endocrine Disruption: Chemicals that mimic or block hormones can alter normal hormonal balance, impacting growth and development. Genetic Mutations: Exposure to certain toxicants can cause mutations in DNA, leading to hereditary disorders or cancer.
