Alberta has a comprehensive air quality management system that is used to address air quality issues and concerns. Air quality can be affected by both natural and human sources. When substances from natural and anthropogenic, or human, sources accumulate in the atmosphere, air quality can degrade and affect human and ecosystem health.

Description

Ammonia presents a potential hazard to workers at the work site. Worker exposure to ammonia can occur during its manufacture or in its many industrial applications. To ensure protection against exposure to ammonia, both workers and employers must be aware of its properties, how it affects the body and what to do in emergency situations.

Ammonia emissions from confined feeding operations (CFOs) : control and mitigation

Description

This fact sheet is intended to provide producers and farm managers with information on how to reduce ammonia emissions from livestock housing and manure storage facilities. By reducing ammonia... More ≫

Description

This fact sheet is intended to provide producers and farm managers with information on how to reduce ammonia emissions from livestock housing and manure storage facilities. By reducing ammonia emissions, producers will maintain the quality of the environment, prevent losses of significant portions of nutrients and improve the health and safety of animals and workers. Although there is no direct relationship between ammonia emissions and odour, practices to reduce ammonia emissions can have a corresponding mitigating effect on odour generation.

Description

The purpose of this fact sheet is to provide producers and farm managers with information that will help quantify the amount of ammonia loss that occurs when they apply manure on land. It also provides them with information regarding the factors that positively and negatively affect these losses. The fact sheet is also a good source of information on best management practices producers could use to mitigate and control ammonia losses from the land application of manure.

Nitrate poisoning and feeding nitrate feeds to livestock

Description

While nitrates (N03) are not very toxic to animals, nitrites (N02) are toxic. In ruminant animals such as cattle, sheep, and goats, nitrate is converted to nitrite by bacteria in the rumen. When... More ≫

Description

While nitrates (N03) are not very toxic to animals, nitrites (N02) are toxic. In ruminant animals such as cattle, sheep, and goats, nitrate is converted to nitrite by bacteria in the rumen. When ruminants consume a high nitrate feed, both nitrate and nitrite can accumulate in the rumen, and nitrate poisoning occurs when the nitrite level in the rumen exceeds the capacity of the microbes to convert it to ammonia. This fact sheet addresses some common questions about nitrate poisoning and discusses how to reduce the risk of nitrate toxicity.
