Computers And Air Pollution: What's The Connection?

Computers are a source of indoor air pollution. They can decrease the perceived air quality, increase Sick Building Syndrome (SBS) symptoms and decrease office productivity. The age, size, operating time, and temperature of computers affect the levels of polycyclic aromatic hydrocarbons (PAHs) emitted. PAH levels in rooms with computers are 2-25 times higher than in outdoor air.

Computers are an indoor source of air pollution

In a study, the levels and composition of polycyclic aromatic hydrocarbons (PAHs) in the indoor air of an office, a computer room, and a server room were monitored. The computer components were also heated in an oven, and the subsequent release of PAHs was monitored. The study found that the PAH profiles inside the computers were similar to those in the indoor air, suggesting that the PAHs released from computers contribute to indoor air pollution.

The age, size, operating time, and temperature of computers affected PAH levels. Gaseous naphthalene and phenanthrene were the dominant compounds in the indoor environment. The levels of PAHs in an office, a computer room, and a server room were 2-25 times higher than those in outdoor air or in a room without a computer.

This demonstrates that computers are an indoor source of air pollution, and the impact of this pollution can be mitigated by increasing the ventilation rate in the room.

Personal computers are an important source of indoor air pollution. They can decrease perceived air quality, increase Sick Building Syndrome (SBS) symptoms and decrease office productivity.

A study found that the levels of polycyclic aromatic hydrocarbons (PAHs) in an office, a computer room, and a server room were 2-25 times higher than those in outdoor air or in a room without a computer. The age, size, operating time, and temperature of computers affected PAH levels.

The PAH profiles inside the computers were similar to those in the indoor air, suggesting that the PAHs released from computers contribute to indoor air pollution. The study also confirmed the emission of PAHs from computer components.

The ventilation rate in an office with a 3-month-old PC would need to be increased several times to achieve the same perceived air quality as an office without PCs.

Computers can decrease perceived air quality

In one study, the levels and composition of polycyclic aromatic hydrocarbons (PAHs) in the indoor air of an office, a computer room, and a server room were monitored. The computer components were also heated in an oven, and the subsequent release of PAHs was monitored. The study found that the PAH profiles inside the computers were similar to those in the indoor air, suggesting that the PAHs released from computers contribute to indoor air pollution.

Another study found that the levels of PAHs in rooms with computers were 2-25 times higher than in outdoor air or in a room without a computer. The age, size, operating time, and temperature of computers affected PAH levels.

The ventilation rate in an office with a 3-month-old PC would need to be increased several times to achieve the same perceived air quality as an office without a PC.

Computers can increase Sick Building Syndrome (SBS) symptoms

The study also found that the ventilation rate in an office with a 3-month-old PC would need to be increased several times to achieve the same perceived air quality as an office without a PC. This suggests that computers can contribute to poor indoor air quality, which can trigger or worsen SBS symptoms.

Another study confirmed that computers emit polycyclic aromatic hydrocarbons (PAHs), which are a type of indoor air pollutant. The levels of PAHs in rooms with computers were found to be 2-25 times higher than in outdoor air or in a room without a computer. The age, size, operating time, and temperature of computers all affected PAH levels.

The health risks associated with inhaling PAHs in an office environment were also evaluated, and it was found that the emission of PAHs from computer components could pose a risk to human health. Therefore, it is important to be aware of the potential impact of computers on indoor air quality and SBS symptoms, and to take steps to mitigate this risk, such as ensuring adequate ventilation or using low-polluting PCs.

To mitigate the potential negative impacts of computers on indoor air quality and office productivity, it is important to ensure adequate ventilation in spaces with computers. The ventilation rate in an office with a 3-month-old PC would need to be increased several times to achieve the same perceived air quality as an office without PCs.
