Chemistry add in for word 2016 skin#

Some adjuvants may increase the amount of pesticide that spreads onto or sticks to your skin, and the amount that is absorbed through your skin.Д¬anadian pesticide use is regulated through a system shared by federal, provincial and municipal governments. In addition, adjuvants (a chemical added to a pesticide to increase its effect) may be added to a spray solution. In some cases, formulations such as emulsifiable concentrates may be more easily absorbed than water solutions.

For example, your skin absorbs liquids more easily than powders. It is important to know what form the pesticide is in because the form can have an impact on how hazardous the chemical may be. Some examples of words and abbreviations used for pesticide label formulation statements are:Д - Dust or Powder DF - Dry Flowable E or E C - Emulsifiable Concentrate F - Flowable G - Granular P - Pellet S - Solution SC - Sprayable Concentrate SP - Soluble Powder WDG - Water Dispersible Granules WP - Wettable Powder WS - Water Soluble ConcentrateДЄdapted from: Grower Pesticide Safety Course Manual, Chapter 5 - Pesticide Formulations, Ontario Pesticide Education Program, University of Guelph Ridgetown Campus.

Gaseous pesticides are typically fumigants (can be sold as liquids or gases).ДЄbbreviations are often used with the trade name on the pesticide label to indicate the type of formulation.

Solid formulations include dusts, particulates, granulars, pellets, soluble granules, soluble powders, baits, tablets, dry flowables and wettable powders.

Liquid formulations include suspensions (flowables), solutions, emulsifiable concentrates, microencapsulated suspensions, and aerosols.

Pesticides are formulated (prepared) in liquid, solid and gaseous forms. *under review at the time of publication of this document

Stable in sunlight (do not degrade quickly).

Disrupts nerve-impulse transmission, (increases sodium ion flow into axon), which stimulate nerve cells and eventually causes paralysis.

Methomyl (in Canada some uses are proposed to be cancelled).

Propoxur (some uses of this insecticide, such as control of mosquitoes, black flies, all indoor use except bait trays, are to be phased out in Canada).

Carbaryl (Banned in European countries, only certain uses will be cancelled in Canada due to concerns of health risks).

The health hazard to humans and animals is mild with herbicides and fungicides, while greater with insecticides.

Includes insecticides, herbicides and fungicides.

In general, are less persistent in the environment than the organochlorine family.

Control pests by acting on the nervous system (interfere with nerve-impulse transmission by disrupting the enzyme (cholinesterase) that regulates acetylcholine (a neurotransmitter).endolsulfan (use not permitted after December 31, 2016).Traditionally used for insect and mite control, but many are no longer used due to their ability to remain in the environment for a long time.Generally persistent in soil, food, and in human and animal bodies (does not breakdown quickly).Controls pests by disrupting nerve-impulse transmission (disrupts ion flow at the axon/synapse level).Organochlorines (Chlorinated Hydrocarbons) However many are being phased-out or used only in critical applications. Organophosphates are used because they are less persistent (breakdown faster) in soil, food or feed for animals than other families, such as organochlorine pesticides.With a few exceptions, most are highly toxic.They control pests by acting on the nervous system (for example, the pesticide interferes with nerve-impulse transmissions by disrupting the enzyme (cholinesterase) that regulates acetylcholine (a neurotransmitter)). Most organophosphates are insecticides.

There are several types of pesticides in this family, depending on the exact chemicals used. Some common families include: Organophosphates A pesticide product may have active ingredients from more than one chemical family. Pesticides are often grouped into 'families' because they share similar chemical properties, or they act on the pest in the same way. There are many, many more types of pesticides than what is listed here. The table below lists some common categories, their purpose, and what products they are normally found in. Pesticides include a wide range of products - many of which you may use every day.
