What does chronic exposure to pesticides often affect in the body?

1. Immediate symptoms and reactions

2. Essential enzymes and long-term health

3. Only external symptoms

4. Short-term memory

The correct answer is: Essential enzymes and long-term health

Chronic exposure to pesticides can lead to significant impacts on essential enzymes and long-term health. Unlike immediate exposure, which may result in acute symptoms such as nausea or headaches, chronic exposure refers to long-term contact that accumulates over time, often at low levels. This consistent contact can disrupt biological processes and negatively impact enzyme function, which plays a critical role in metabolism and other physiological processes. Additionally, long-term health effects may include various health issues, such as endocrine disruption, reproductive problems, and heightened risks for certain diseases, linking pesticide exposure to broader and more serious health concerns. Understanding this aspect highlights the importance of considering the cumulative impact of pesticides over time instead of solely focusing on immediate or external symptoms.
