With little public notice, today and tomorrow 9 miles of East Bay shoreline is to be sprayed by helicopter bombardment with Imazapyr, an herbicide pesticide. We're told it's safe. Get the facts. Go to www.eastbaypesticidealert.org. Under Oakland's herbiciding hills plan click on Imazapyr. 48 studies cited, 18 EPA; 1 Forestry Service; myriad chemical industry Toxicological facts: expect eye and skin irritation. Animal studies showed stomach ulcers and intestinal lesions. Chronic toxicity? Oh, yes. Animal studies highlighted fluid accumulation in the lungs; congestion of the brain; abnormal blood formation in the spleen; blood pooling in the liver; increase in thyroid cysts. Not yet called carcinogenic by EPA, "carcinogenic concerns" include: increase in brain and thyroid tumors and cancers in rats.
EPA says "....terrestrial and aquatic plant species... in jeopardy... use of Arsenal (Imazapyr product)." A related herbicide has high chronic toxicity to fish at concentrations less than 1ppm. EPA notes its half-life is 17 months. When it enters drinking water sources, ozone degrades only half. Drift and resistance, like antibiotic resistance, is common with pesticides. Cross resistance is seen with Imazapyr.
A neurotoxic breakdown product causes nerve lesions and symptoms similar to Huntington's disease.
People needed jobs: manual removal is a safe answer.

Also part of the Spartina pesticides program: Glyphosate products. Monsanto's Roundup is one example of a typical Glyphosate-based product.What's Wrong With Roundup
In September 2006 the governors of California, Oregon, and Washington entered into the "West Coast Governors' Agreement on Ocean Health" (WCGA). One of several "Action Coordination Teams" is dedicated to ridding the entire West Coast of "non-native" spartina:

spartina is the horrifying invasive the proponents of this
program claim it to be, is debatable. In Willapa
Bay, Washington, oyster farmers are losing their
livelihoods, not because of cordgrass, but because of their local
spartina project dumping the very same chemicals into their
bay. They question the danger of spartina, pointing out its benefits:
"Spartina is a C-4 plant,
sequesters more CO2 than other kinds of
vegetation. Stabilizes the shoreline, keeps the bay water clean and
free of algae bloom."
other parts of the country they are deliberately planting the same type
of cordgrass, and treating it as almost
endangered. It has also been
found useful in bioremediation of certain toxic compounds.
As for non-toxic alternatives, undoubtedly manual removal of large areas of cordgrass presents a challenge, but it's certainly not impossible. Rather than spending an obscene amount of money on chemicals, that money would be better spent on hiring the many unemployed, who are literally starving for work. Or organize volunteers as they do in Puget Sound for the annual Spartina Dig. If it's such a big emergency, how about holding those responsible who planted the cordgrass in the first place, the U.S. military? Clearly they have the people power and physical strength to remove it manually, without declaring chemical warfare on the bay.
