Sublethal effects of a pure polychlorobiphenyl on mice

Experimental and Molecular Pathology, 1977
Abstract Sexually mature, weight-stable male mice were dosed by oral intubation with either 0, 200, 500, or 1000 mgm/kgm of 2,4,5,2′,4′,5′-hexachlorobiphenyl (PCB), dissolved in peanut oil, and housed for 28 days in groups of five in metabolic cages.

THE SUBLETHAL EFFECTS OF SYNTHETIC INSECTICIDES ON INSECTS

Biological Reviews, 1969
Summary The synthetic insecticides have been used in steadily increasing quantities since the Second World War and are non‐specific poisons, and so pose the possibility of sublethal effects on wild populations of animals. The organochlorine insecticides in general, and some of the cyclodienes in particular, are usually much more persistent than the ...

Sublethal effects of epoxiconazole on the earthworm Aporrectodea icterica

Environmental Science and Pollution Research, 2015
Earthworms play a key role in agroecosystem soil processes. This study aims to assess the effects of different doses of a commercial formulation of epoxiconazole (Opus®), a persistent and widely used fungicide, on the earthworm Aporrectodea icterica. A laboratory study was conducted in a natural soil in order to measure effects of Opus® on earthworm ...

Effect of sublethal doses of cyanide on glucose catabolism

Biochemical Pharmacology, 1975
Abstract The effect of cyanide on the metabolic degradation of glucose in the mouse was investigated by comparing the rate and extent of production of respiratory 14 CO 2 from specifically labeled carbon atoms of glucose, gluconate and glucuronate. Glucose in the untreated animals was metabolized via three pathways: Embde.n-Meyerhof-Parnas pathway ...

Sublethal effects of malathion on channel catfish,Ictalurus punctatus

Bulletin of Environmental Contamination and Toxicology, 1990
Malathion (O,O-dimethyl-S-1, 2-di-(ethoxycarbamyl)ethyl phosphorodithioate) is an organophosphate which is a widely used pesticide in the United States. This pesticide seems to be more toxic to insects and fish than to mammals due to the lack of hydrolytic enzymes in insects and fish. Malathion clearly affects the hematology of fish. The study reported

Sublethal effects of neonicotinoids on insect pests

Entomologia Generalis
Insecticides are currently the most cost-effective tools for quickly and effectively managing insect pest populations. Among these, neonicotinoids have been widely used worldwide. However, the abiotic and biotic factors may produce spatiotemporal concentration changes that ultimately affect the intended doses/concentrations.

Sublethal effects of chronic lead ingestion in mallard ducks

Journal of Toxicology and Environmental Health, 1976
Mallard drakes (Anas platyrhynchos) fed 1, 5, or 25 ppm lead nitrate were bled and sacrificed at 3-wk intervals. No mortality occurred, and the pathologic lesions usually associated with lead poisoning were not found. Changes in hematocrit and hemoglobin concentration did not occur.

Sublethal Effects of Waterborne Herbicides in Tropical Freshwater Fish

Bulletin of Environmental Contamination and Toxicology, 2011
The study evaluated the sublethal effects of the herbicides glyphosate (Roundup) and diuron (Hexaron) and the mixture of them, used extremely in agriculture, through biomarkers in fish. The glutathione S-transferase activity increased (74%) and catalase activity decreased (37%) at the higher exposure concentration of Hexaron in comparison to the ...

Sublethal Effects of Contaminants on Aquatic Organisms

1984
This study seeks ways to measure chronic biological effects in the context of a complex ecosystem. Laboratory studies and single contaminant exposure bioassays must, of necessity, be continued to give baselines and more precise indications of effects of exposure. But in addition there must be methods of gauging impacts in the "real world".

Sublethal effects of nitenpyram on the development of silkworm

Science of The Total Environment
The utilization of nitenpyram for aphid and whitefly control may induce environmental contamination and negative repercussions on non-target organisms. Formerly, we found that nitenpyram would pollute the peripheral and sub-peripheral areas of the adjacent mulberry orchard.
