Question

Accepted Answer

The correct answer is Option D.

Methylene chloride (Dichloromethane) Dichloromethane, also known as methylene chloride, is one of the polyhalogen compounds present in the form of solvent. Low levels of methylene chloride exposure in the air can cause slight hearing and vision impairment.

Answer

Exposure to lower levels of a compound in air can lead to slightly impaired hearing and vision. The compound responsible for this effect is Methylene chloride (option D).

Below is a detailed explanation of why methylene chloride can cause impaired hearing and vision:

Methylene Chloride (Dichloromethane):
Methylene chloride is a colorless liquid with a sweet odor. It is commonly used as a solvent in various industrial processes and products, such as paint strippers, adhesives, and aerosol propellants.

Impaired Hearing:
Exposure to lower levels of methylene chloride in the air can lead to slightly impaired hearing. This is because methylene chloride is metabolized in the body to carbon monoxide, which can interfere with the delivery of oxygen to the inner ear. The inner ear is responsible for converting sound vibrations into electrical signals that are transmitted to the brain for interpretation. When the inner ear does not receive sufficient oxygen, it can result in reduced hearing sensitivity.

Impaired Vision:
Methylene chloride exposure can also cause slightly impaired vision. This compound can be converted to formaldehyde in the body, and formaldehyde is known to be toxic to the optic nerve. The optic nerve is responsible for transmitting visual information from the eye to the brain. Damage to the optic nerve can result in blurred vision, decreased visual acuity, and even vision loss.

Other Health Effects:
In addition to impaired hearing and vision, exposure to methylene chloride can have other adverse health effects. It is a known carcinogen, meaning it has the potential to cause cancer. Prolonged or high-level exposure to methylene chloride has been associated with an increased risk of liver, lung, and pancreatic cancer. It can also cause irritation to the skin, eyes, and respiratory system.

Regulations and Safety Measures:
To protect workers and the general public from the harmful effects of methylene chloride, regulatory agencies have established exposure limits and safety measures. For example, the Occupational Safety and Health Administration (OSHA) in the United States has set a permissible exposure limit (PEL) of 25 parts per million (ppm) for methylene chloride in the workplace over an 8-hour time-weighted average. Employers are required to implement engineering controls, such as ventilation systems, to minimize employee exposure. Personal protective equipment, such as respirators and gloves, should also be used when handling methylene chloride.

In conclusion, exposure to lower levels of methylene chloride in the air can lead to slightly impaired hearing and vision. It is important to take appropriate safety measures and follow regulations to minimize exposure to this compound and protect our health.
