VOCs, for instance, are released during the handling and processing of animals, as well as from the use of various chemicals and disinfectants. These compounds react with NOx in the presence of sunlight to form ground-level ozone, a major component of smog. Ground-level ozone is a powerful respiratory irritant and can cause coughing, wheezing, and other respiratory issues, especially in vulnerable populations such as children and the elderly. It can also exacerbate existing respiratory conditions, such as asthma.

Particulate matter, another significant pollutant, is generated through the handling and transportation of animals, as well as from the incineration of waste materials. PM is a complex mixture of solid particles and liquid droplets, which can be inhaled and cause serious health problems. Fine particulate matter (PM2.5) can penetrate deep into the lungs and even enter the bloodstream, leading to respiratory and cardiovascular diseases. The release of these pollutants not only affects the immediate surroundings of the facility but can also have far-reaching consequences, contributing to air pollution on a larger scale.

The impact of these emissions is not limited to the immediate vicinity of the animal testing facilities. The pollutants can be carried by wind, affecting nearby communities and potentially leading to the degradation of air quality over a broader area. This can result in increased levels of air pollution, which may have long-term effects on public health and the environment. It is crucial to recognize that these facilities, while essential for scientific research, must operate with strict environmental regulations to minimize their impact on air quality.

Addressing this issue requires a multi-faceted approach. Firstly, animal testing facilities should implement advanced emission control technologies to capture and reduce the release of VOCs and NOx.
