Description

Alberta Research Council was contracted by Alberta Environment to conduct four reviews of complaints about coalbed methane activities affecting private water wells, to independently assess the scientific evidence and provide conclusions identifying whether or not the water wells had been impacted by coalbed methane or conventional oil/gas extraction activities.

Description

Coal continues to be an important fuel worldwide for the generation of electricity. A previous report by the author reviewed technologies available or under development to minimize the amount of air pollutants and greenhouse gases emitted from coal-fired power plants. This report discusses further developments and improvements since 2001 in air emissions control technology.

Description

Results of a field study conducted in the summer of 2000 showed that when the antioxidant ethylene diurea (EDU) was applied to crops, there were increases in several parameters. The next step was to verify whether the effects of EDU resulted from EDU-mediated protection against ozone or from plant growth promoting effects of EDU that are independent of ozone. A series of controlled environment trials were designed to test this hypothesis.

Description

Ozone is an important phytotoxic gaseous pollutant and is known or suspected to cause injury in crops, including yield reductions. Studies have been conducted using the antioxidant EDU (ethylene diurea) in programs aimed at the quantification of the effects of ozone on vegetation. For the present study, a protocol making use of EDU as an antioxidant was designed and implemented at a site near the city limits of Fort Saskatchewan, Alberta, an area having elevated ozone levels relative to other areas of the province.

Evaluation of polycyclic aromatic hydrocarbon (PAH) accumulation in plants : the potential use of PAH accumulation as a marker of exposure to air emissions from oil and gas flares

Description

Polycyclic aromatic hydrocarbons (PAHs) are a class of complex substances that are produced during incomplete combustion of fossil fuels. PAHs are one component of air emissions from oil and gas flares. Although PAHs and other substances released from flares may have environmental effects, it is very difficult to determine the extent of exposure of vegetation to flare emissions, and therefore, it is difficult to measure any effects of these emissions. The Air Research Users Group of Alberta Environment commissioned this review of the scientific literature of PAH accumulation within plant material that occurs following exposure to air containing PAHs. The conclusions of this review will contribute to a decision on whether or not to pursue a field investigation into the use of PAH accumulation in plant parts as a marker of exposure of the plants to emissions from oil and gas flares.

Description

This report was commissioned to provide a review and interpretation of the scientific literature that describes the use and effects of chemical ozone protectants. The authors of this report were asked to determine if there was sufficient information available on these substances to warrant a field evaluation of their use. This was done as part of Alberta Environment's efforts to determine if ozone has the potential to cause negative (or positive) effects on plants in the province, with a focus on agricultural crops.
