Which term describes the health impacts associated with repetitive motions and chemical exposure?

The term that accurately describes the health impacts associated with repetitive motions and chemical exposure is "occupational diseases." This classification encompasses a broad range of conditions that arise specifically from the work environment, including those due to prolonged exposure to harmful substances or the repetitive nature of certain tasks.

Occupational diseases can manifest as musculoskeletal disorders from repetitive motions—such as tendonitis or carpal tunnel syndrome—as well as respiratory illnesses or skin conditions resulting from exposure to hazardous chemicals in the workplace. Understanding occupational diseases is crucial for preventing these health issues through appropriate workplace safety measures and regulations.

The other options do not fully capture the essence of the health effects caused by both repetitive motions and chemical exposure. Work-related stress generally refers to psychological or emotional strain that may not include the physical conditions of concern here. Environmental allergies pertain more to allergic reactions triggered by various environmental factors rather than occupational settings specifically. Physical injuries focus on acute trauma or injuries rather than chronic conditions arising from ongoing exposure, as seen with occupational diseases.
