  29. Absorb • To incorporate or take a substance into another material or a body • Compare… Adsorb

  30. Acaricide • A pesticide used to kill mites, spiders, and ticks

  31. Acceptable Daily Intake(ADI) • The amount of chemical a person can be exposed to on a daily basis over an extended period of time (usually a lifetime) without suffering deleterious effects

  32. Acceptable Exposure Limit(AEL) • The acceptable permissible concentration of a chemical in a work environment (generally as ppm in air) for a defined period of time (generally 8 hours). • See also… MEL, OEL, PEL, STEL, TLV, TWA

  33. ACGIH • American Conference of Governmental Industrial Hygienists, Inc. • An organization open to all practitioners in industrial hygiene, occupational health, environmental health, or safety • Assigns TLVs (for our purposes) to chemical products including pesticides

  34. Acid Equivalent(a.e. or ae) • The portion of a compound or formulated product that theoretically could be converted back to its corresponding acid

  35. Acre(a or ac) • An English measure unit of area equal to 43,560 square feet

  36. Acre-Foot (ac ft) • The English system volume equivalent to one acre of water or soil which is 1 foot deep • 1 ac x 1 ft, 0.5 ac x 2 ft, or other variant • (43, 560 square feet x 1 ft = 43,560 cubic feet of either water or soil) • See also… Surface acre

  37. Activation • The process by which a surface applied herbicide is moved into the soil where it can be absorbed. This is normally accomplished by rainfall, irrigation or tillage

  38. Active Ingredient (a.i. or ai) • The chemical(s) in a formulated product that is (are) principally responsible for the pesticide’s effect; listed as active ingredient(s) on the label

  39. Acute Exposure • One or multiple doses of short duration spanning up to but no more than 24 hours

  40. Acute Toxicity • Any poisonous effect produced within a short period of time, up to 96 hours, following an exposure • See also… Chronic toxicity, • Subchronic toxicity

  41. Adaptation • The process whereby repeated exposures to small amounts of a chemical cause a plant or animal population to become tolerant to the chemical by permitting only tolerant individuals to propagate the population

  42. Additive Effect • A situation in which the combined effect of two or more chemicals is equal to the simple sum of the effect of each chemical alone. This is the most commonly expressed effect of combined chemicals • See also…Antagonism, Synergism

  43. Adjuvants • Compounds which, when added to pesticides, act as wetting or spreading agents, stickers, penetrants, emulsifiers, drift control agents, etc. and make the pesticide easier to handle, mix, or apply, or increase its effectiveness

  44. Adsorb • To hold or bind a substance onto the • surface of another material or a body • Compare… Absorb

  45. Adverse Effect • A biochemical change, functional impairment, or pathologic lesion that affects performance of the whole organism, or reduces an organism’s ability to respond to an additional environmental challenge

  46. Aerial Application • Application of a pesticide by using an airplane or helicopter as the vehicle from which the material is dispensed in a broadcast pattern over the landscape; most commonly used for insecticidal applications but some herbicidal work is also done in this manner

  47. Aerobes • Organisms which require free oxygen to live

  48. Aerosol(A) • A suspension of liquid or solid particles in air; a pesticide formulation designed to be suspended in the air by the action of a propellant gas causing fine droplets to be produced through a nozzle

  49. Agitation • Stirring or mixing in a pesticide tank to retain an even distribution of an emulsified or suspended pesticide

  50. Algae • Primitive, chiefly aquatic, unicellular or multicellular plants that lack true stems, roots or leaves, but usually contain chlorophyll
