Why Ban 2,4-D and Ignore (Likely to be Carcinogenic) Permethrin or Glyphosate in Urban Streams????
Concentrations were always lowest for 2,4-D
The Ministry Of Environment / McGuinty Government banned the least prolific/toxic product and exempted the most prolific/toxic, according to the Ontario Pesticide Ban Rationale. Permethrin is Likely to Cause Cancer according to the EPA
Sure-Gro IP Inc. is reclassifying a Permethrin based product to Domestic Use (Class 6) as opposed to a controlled product for non cosmetic usages (Class 7).
Sounds like higher levels of Permetherin in Urban Steams to follow. At the parts per zillion range, but thats enough to cause concern for fearmongering lunatics like Canadian Association of Physicians for the Environment, Ontario College of Family Physicians, David Suzuki, Environmental Defence, Equiterre, Canadian Environmental Law Association, Or is it?
Uses
- Permethrin is registered for use on/in numerous food/feed crops, livestock and livestock housing, modes of transportation, structures, buildings (including food handling establishments), Public Health Mosquito abatement programs, and numerous residential use sites including use in outdoor and indoor spaces, pets, and clothing (impregnated and ready to use formulations).
- According to Agency data, approximately 2 million pounds of permethrin are applied annually to agricultural, residential and public health uses sites. The majority of permethrin, over 70%, is used in non-agricultural settings; 55% is applied by professionals, 41% is applied by homeowners on residential areas, and 4% is applied on mosquito abatement areas.
- Permethrin is a restricted use pesticide for crop and wide area applications (i.e., nurseries, sod farms) due to high toxicity to aquatic organisms, except for wide area mosquito adulticide use. It is a general use pesticide for residential and industrial applications.
- Permethrin also has non-FIFRA pharmaceutical uses as a pediculicide for the treatment of head lice and scabies. The Food and Drug Administration (FDA) approves use of the pesticide-containing pharmaceutical under FFDCA.

Health Effects
Permethrin is a member of the pyrethroid class of pesticides. Similar to other pyrethroids, permethrin alters nerve function by modifying the normal biochemistry and physiology of nerve membrane sodium channels. However, EPA is not currently following a cumulative risk approach based on a common mechanism of toxicity for the pyrethroids. Although all pyrethroids interact with sodium channels, there are multiple types of sodium channels and it is currently unknown whether the pyrethroids have similar effects on all channels. Nor do we have a clear understanding of effects on key downstream neuronal function e.g., nerve excitability, nor do we understand how these key events interact to produce their compound specific patterns of neurotoxicity. There is ongoing research by the EPA’s Office of Research and Development and pyrethroid registrants to evaluate the differential biochemical and physiological actions of pyrethroids in mammals. This research is expected to be completed by 2007. When available, the Agency will consider this research and make a determination of common mechanism as a basis for assessing cumulative risk. Therefore, the human health risk assessment and RED document only considered the effects of permethrin.
Additionally, the Agency classified permethrin as “Likely to be Carcinogenic to Humans” by the oral route. This classification was based on two reproducible benign tumor types (lung and liver) in the mouse, equivocal evidence of carcinogenicity in Long- Evans rats, and supporting structural activity relationship information.
"The research that was done by the province looked at the concentration before and after the ban came into effect, and in some cases those drops are as much as 97 per cent reduction in urban streams," said Gideon Forman the executive director of the Canadian Association of Physicians for the Environment.
"The sort of thing we were hoping would happen: that kids would be protected, that water would be protected, that urban streams would be protected is happening, and it is very gratifying," stated Gideon Forman, Executive Director for the Canadian Association of Physicians for the Environment.
- In Canada, water quality in urban streams improved by 86% one year after the ban of certain lawn pesticides. Streams feed into our sources of drinking water and pesticides migrate into well water.

The Ontario ban is also improving water quality. The provincial Ministry of Environment studied pesticide concentrations in ten urban streams before and after their ban came into effect (2008 vs. 2009) and compared the findings. The study’s author states: “Concentrations of 2,4-D, dicamba, MCPP, total phenoxy herbicides and total insecticides were significantly lower in 2009…” In fact, in some streams pesticide concentrations were up to 97% lower. That’s an extraordinary result and suggests a province-wide pesticide ban in B.C. would have similar benefits for local waterways. – Prevent Cancer Now
Objective #3: Compare concentrations of detected pesticides to water quality criteria for
the protection of aquatic life to assess potential effects on stream ecosystems.Water quality criteria for the protection of aquatic life have been developed for over half
(21/33) of the pesticides that were detected at a concentration > 1 ng L-1. Pesticide
concentrations in urban stream water samples rarely exceeded these criteria. In 2008,
carbaryl exceeded a criterion in 12.5% (3/24) of samples, permethrin 4.2% (1/24) and
total phenoxy herbicides 3.4% (3/88). The only pesticide to exceed a criterion in 2009
was the insecticide permethrin, with one exceedance in 24 samples. Permethrin is
registered for use in Canada in a variety of domestic insecticide products and certain
exceptions for permethrin use are allowed under Ontario’s cosmetic pesticides ban.
Concentrations of glyphosate and its degradate
aminomethylphosphonic acid (AMPA) were not significantly different between 2008 and
2009 which may reflect that there are exceptions to the ban for certain uses of
glyphosate.

Description of Instrument:
The registrant, Sure-Gro IP Inc, has requested that the product Antout Ant Control (PCP 31047) be reclassified into Class 6 under Ontario Regulation 63/09 made under the Pesticides Act. This product is currently classified as a Class 7 pesticide. Sure-Gro IP Inc has informed the ministry that Health Canada's Pest Management Regulatory Agency (PMRA) has approved the amendments to the product label to remove certain uses of the pesticide in, on or over land. Based on the approved label amendments and information provided to the ministry on the distribution and marketing of the newly labeled product, a proposal for reclassification is being considered. Health Canada's Pest Management Regulatory Agency assesses pesticides for their risks to human health and the environment, and examines the efficacy and value of pest control products in registering products under the Pest Control Products Act for sale and use across Canada. In Ontario, the Pesticides Act and Ontario Regulation 63/09 stipulate that federally registered pesticides must be classified in Ontario before they are legal for sale and use. PCP 31047 Class 6 includes products that are designated as Domestic under the federal legislation and meet the description of “Least Hazardous” in the Pesticide Classification Guideline for Ontario. The container size of Class 6 products must be less than or equal to 1 kilogram or 1 litre in size. Class 7 Pesticides are controlled sales domestic pesticides with cosmetic and non-cosmetic uses. Products are only allowed to be used for non-cosmetic purposes. Controlled sale products cannot be used to control lawn or garden pests, but can be used to control biting or stinging pests as directed on the label. These products can be used inside your home or immediately around the outside perimeter to control pests for non-cosmetic purposes. For additional information about which pesticide products are classified in Ontario, please visit the Ministry's Website (see link under Additional Information).
