Studies Link Canine Cancers To Lawn Chemicals
“Lawn chemicals, particularly, ones containing 2,4-D, have been linked to at least two types of canine cancers. Studies found that lawn chemicals travel to neighboring yards and inside homes, and chemicals have been found in the urine of dogs whose owners did not spray their lawns.”1
Sadly, the evidence that lawn chemicals are linked to cancers in dogs has been accumulating steadily over the past 20 years. Even if you don’t own a pet this should raise alarms for anyone who cares about children or just your own health.
As Prof. John Reiff of Colorado State University reminds us, “Animals may be sensitive indicators of environmental hazards and provide an early warning system for public health intervention, as exemplified by the iconic canary in the coal mine.”2 He shared the results of work at Purdue University’s School of Veterinary Medicine that found exposure to lawns or gardens treated with herbicides was associated with an increased risk of bladder cancer in dog breeds studied.
While there is current controversy in public health circles and the news about the use of Monsanto/Bayer’s Roundup (glyphosate), another herbicide, 2,4-dichlorophenoxyacetic acid (2,4-D), has a controversial history as well. It was banned in Sweden for use in the lumber industry because of concerns about cancer among lumberjacks in 1988 and banned for general use in 1990.
