Ecological Effects
Effects on birds: Dicofol is slightly toxic to birds. The 8-day dietary LC50 is 3010 ppm in bobwhite quail, 1418 ppm in Japanese quail, and 2126 ppm in ring-necked pheasant. Eggshell thinning and reduced offspring survival were noted in the mallard duck, American kestrel, ring dove, and screech owl.
Effects on aquatic organisms: Dicofol is highly toxic to fish, aquatic invertebrates, and algae. The LC50 is 0.12 mg/L in rainbow trout, 0.37 mg/L in sheepshead minnow, 0.06 mg/L in mysid shrimp, 0.015 mg/L in shell oysters, and 0.075 mg/L in algae.
Effects on other organisms: Dicofol is not toxic to bees.

Famous quotes containing the words ecological and/or effects:
“The hatred of the youth culture for adult society is not a disinterested judgment but a terror-ridden refusal to be hooked into the, if you will, ecological chain of breathing, growing, and dying. It is the demand, in other words, to remain children.”
—Midge Decter (b. 1927)
“I am fearful that the paper system ... will ruin the state. Its demoralizing effects are already seen and spoken of everywhere ... I therefore protest against receiving any of that trash.”
—Andrew Jackson (1767–1845)
