Sublethal effect of malathion to three salmonid species

Bulletin of Environmental Contamination and Toxicology, 1974
Malathion is one of the most widely used insecticides in the United States since the controlled use of DDT was put into effect. Malathion is used to control a variety of insect pests on rangeland, forest lands and agricultural lands. Many of these treated areas contain streams and lakes which harbor fish populations.

Toxicity testing of sublethal effects of dredged materials

Archives of Environmental Contamination and Toxicology, 1988
A series of toxicity tests were conducted on liquid and suspended solid phase fractions of sediments from the Port of Hampton Roads, Virginia. The respiration and hyporegulatory capacity of grass shrimp proved to be sensitive indices of sublethal stress associated with exposure to contaminated sediments. On the other hand, hyper-regulatory capacity was

Neurobehavioral effects of repeated sublethal soman in primates

Pharmacology Biochemistry and Behavior, 1985
Juvenile male baboons were trained to perform a match-to-sample discrimination task; effects of repeated sublethal exposure to the organophosphate nerve gas, soman, upon task performance were then explored. Both acute and subchronic exposure schedules were employed, and soman potency was verified by assay of soman-induced inhibition of ...

Sublethal Effects of Fire Smoke

Fire Technology, 2004
Fire smoke toxicity has been a recurring theme for fire safety professionals for over four decades. There especially continue to be difficulty and controversy in assessing and addressing the contribution of the sublethal effects of smoke in hazard and risk analyses. The Fire Protection Research Foundation (FPRF), the National Institute of Standards and

DDT: Sublethal Effects on Brook Trout Nervous System

Science, 1969
When brook trout are exposed for 24 hours to sublethal doses of DDT, the cold-blocking temperature for a simple reflex, which shows lability related to thermal history, is altered in a way suggesting that DDT is affecting the thermal acclimation mechanism.

Sublethal effects of cadmium ingestion on mallard ducks

Archives of Environmental Contamination and Toxicology, 1984
Juvenile mallard (Anas platyrhynchos) drakes were fed diets containing 0, 50, 150, or 450 ppm cadmium for 42±1 days in order to assess the impacts of cadmium ingestion on energy metabolism and tissue metal concentrations in this species.

Sublethal effects of iridovirus disease in a mosquito

Oecologia, 1999
Recognition of the importance of debilitating effects of insect virus diseases is currently growing. Commonly observed effects of sublethal infection at the individual level include extended development times, reduced pupal and adult weights, and lowered fecundity.

Sublethal Effects of Neurotoxic Insecticides on Insect Behavior

Annual Review of Entomology, 1988
PERSPECTIVES AND OVERVIEWThe behavior of insects, and all animals, is governed by interactions amongneurons within their nervous systems. Insecticides have been selected andsometimes designed for their remarkable ability to kill insects. Most attackspecific sites within the insect’s nervous system (59, 63; see section on modesand sites of action ...

The Sublethal Effects of Pesticides on Beneficial Arthropods

Annual Review of Entomology, 2007
Traditionally, measurement of the acute toxicity of pesticides to beneficial arthropods has relied largely on the determination of an acute median lethal dose or concentration. However, the estimated lethal dose during acute toxicity tests may only be a partial measure of the deleterious effects.
