PAN Applauds EPA Suspension Of DCPA, Calls For Quicker Action (PAN, 8 Aug 2024)     'According to EPA documents, exposure to DCPA can lead to changes in fetal thyroid hormones that are linked to low birth weight, impaired brain development, decreased IQ, and impaired motor skills observed later in life. Dangerous exposure levels that could cause harm are low enough that a pregnant individual could be exposed to DCPA without experiencing adverse health effects to their own body, while the fetus could experience permanent and significant lifelong adverse effects.     In the meantime, this product continued to be used on lawns, turf applications, and food crops,    While PAN is pleased that the emergency suspension was put into place, we are deeply disappointed in the flawed processes that delay actions that would effectively protect public health. EPA knew of the potential for harm posed by DCPA for eighteen years before taking the first step to suspend it, and then it took another ten years from that first request for more studies on DCPA to finally suspend its registration. That’s nearly three decades worth of exposure to a dangerous herbicide.    SNAP Comment: Dacthal (DCPA or dimethyl tetrachloroterephthalate) is not and apparently has not historically been registered in Canada. The same flawed process of evaluation also applies to Canada. It is classified as an Alkyl Phthalate but also contains 4 clhlorine atoms.

Coffee grounds might be the answer to agricultural contamination: Here’s how (by 
By Harriet Reuter Hapgood, euronews.green , 25/03/2024)     'On a domestic level, try directing your cafetiere contents to your garden, not your bin: used coffee grounds are excellent as an addition to home compost bins and wormeries, a mulch for roses and a deterrent to snails. And on a global scale, science might have the answer.   Scientists from Brazil’s Federal Technological University of Paraná found that leftover coffee can absorb bentazone, a herbicide frequently used in agriculture.   When old coffee grounds are activated with zinc chloride, their carbon content becomes 70 per cent more efficient in removing the herbicide.   The European Environment Agency has highlighted dangerous levels of bentazone in surface water, exceeding levels set in the Water Framework Directive and putting European Green Deal targets for pesticide use in jeopardy.  The UK’s Environment Agency cites bentazone as having the potential to affect long-term water quality and lead to an increased need to treat the UK’s drinking water sources. The herbicide has been shown to impact human health if it is inhaled, ingested or absorbed through the skin.'   SNAP Comment: Bentazone is widely used for a variety of crops including soybeans, alfalfa, beans, corn, peas, peppers, and sorghum. It is used in Europe and approved in the US, but not in Canada at present. As the test has only been done with bentazone, it is unknown at present whether this method would work for other herbicides or pesticides in general. 

Common Herbicide Contributes to Development of Inflammatory Bowel Disease    (Beyond Pesticides, October 25, 2022) Inflammatory bowel disease (IBD) may be exacerbated by exposure to the herbicide propyzamide, used in both agriculture and on ornamental lawns and landscapes, according to research published in the journal Nature this month.  Recent data show that the number of people living with Crohn’s disease and ulcerative colitis, common types of IBD, have risen annually by 3.4% and 2.8% respectively, between just the years 2001 to 2018.   (S)cientists cross-referenced data from the U.S. Environmental Protection Agency’s ToxCast database to screen hundreds of different chemicals that had an affect on intestinal inflammation. Ultimately, 20 candidate chemicals were found, and scientists decided to focus on propyzamide due to its broad use patterns in food and in residential areas.   Using a mouse model, scientists found that propyzamide worsened an inflammatory process that had already been triggered by another exposure, but did not initiate the inflammation.    SNAP Comment: As of 4 Nov 2022, there are only 3 propyzamide herbicides registered with the PMRA. Historically there were 5. There are sstill 18 registered formulations in the US. There is only one commercial one, wht a registration expiring in 2026. It is used for control of weeds in alfalfa, trefoil, ornamentals, strawberries, apples, pears, lowbush blueberries, lettuce and established pastures.
