This is an interesting study I received in email #9,627–not kidding.
The impact of emissions from oil and gas industries on animal health is a major concern in western Canada, among beef cattle producers, as their pastures and primary oil and gas facilities often overlap.
We already know that natural gas emissions effect animals because in the Deborah Rogers health impacts case study, The senior veterinary toxicologist at Texas A&M wrote a letter of concern after looking at the air test results concluding that the compounds were problematic to the animal’s health and to the food chain because these compounds are known to be ingested or inhaled and magnify up the food chain in milk and meat.
Why would anyone think natural gas toxins wouldn’t be “problematic” to humans or magnify up into mother’s milk.
These findings indicate that the concentrations of benzene at which health effects in cattle were observed an be explained by proximity to oil and gas infrastructure.
Setbacks are important because no level of exposure to benzene is safe. Based on this study, setbacks should be at least 3,000 feet.
This last finding contributes to better understanding how positioning of oil and gas facilities impacts air quality and may be of considerable impact on assessment and management of risk to health, especially if the findings that long-term exposure to benzene above 0.236 μg/m3 affect cattle fertility is found to be relevant to human health.
