1. What causes the water pollution?

Water pollution can be caused by various factors, including:

• Industrial waste: Discharge of untreated or partially treated wastewater from industries.
• Agricultural runoff: Fertilizers, pesticides, and animal waste from farms.
• Sewage: Untreated sewage from households and communities.
• Oil spills: Accidental or intentional release of oil into water bodies.
• Solid waste: Improper disposal of solid waste, leading to water contamination.
1. What is occupational overuse syndrome?

Occupational overuse syndrome, also known as repetitive strain injury (RSI), is a condition caused by repetitive movements or sustained awkward postures, leading to pain, discomfort, and inflammation in the affected body part. Common examples include carpal tunnel syndrome, tendonitis, and bursitis.

3. What are musculoskeletal problems?

Musculoskeletal problems refer to conditions affecting the muscles, tendons, ligaments, and bones. These problems can be caused by various factors, including poor posture, repetitive strain, and injuries. Common musculoskeletal problems include back pain, neck pain, shoulder pain, and carpal tunnel syndrome.

4. What cautions to be taken while working on the computer?
• Maintain good posture: Sit upright with your feet flat on the floor and your back straight.
• Take regular breaks: Get up and move around every 20-30 minutes.
• Adjust your screen height: The top of the screen should be at eye level.
• Use ergonomic equipment: Invest in an ergonomic chair, keyboard, and mouse.
• Avoid eye strain: Take regular breaks, blink frequently, and adjust the screen brightness.
• Avoid repetitive strain: Take frequent breaks and vary your tasks.
5. Why there is no right way to use a laptop?

Laptops are designed for portability, not for prolonged use in a stationary position. Their small size and fixed screen position can make it difficult to maintain good posture and avoid strain on the neck, back, and wrists.

6. What causes eye strain and how to avoid it?

Eye strain can be caused by prolonged screen exposure, poor lighting, and dry eyes. To avoid eye strain, you can:

• Take regular breaks: Look away from the screen every 20 minutes and focus on a distant object.
• Blink frequently: This helps to keep your eyes moist.
• Adjust screen brightness and contrast: Reduce glare and eye fatigue.
• Use artificial tears: If your eyes feel dry, use eye drops to lubricate them.
6. What type of display screen is suitable to work on a computer?

A matte display screen is generally considered more suitable for computer work as it reduces glare and eye strain.

8. What type of keyboard is suitable to work on a computer?

An ergonomic keyboard is designed to reduce strain on the wrists and hands. It often has a split design and a curved shape to promote a more natural hand position.
