Results. The LC50 for leachate from smoked cigarette butts (smoked filter + tobacco) was approximately one cigarette butt/l for both the marine topsmelt (Atherinops affinis) and the freshwater fathead minnow (Pimephales promelas).Leachate from smoked cigarette filters (no tobacco), was less toxic, with LC50 values of and cigarette butts/l, respectively for Cited by: The aim of the present study is to determine the acute toxicity of three commercial herbicides to fish and midge larvae (Chironomus tentans), an important fish food.
Materials and Methods Three species of freshwater fish were selected for the present study. The fish selected were Labeo rohita, Cir- rhinus mrigala, and Mystus by: In this study, freshwater WQC were developed for 2,4,6-TCP based on its acute and chronic toxicity to freshwater fish, invertebrates and algae, using domestic aquatic organisms.
The toxicity data for 2,4,6-TCP were generated by conducting acute toxicity testing with nine fish and invertebrate species, chronic toxicity testing with four of those Cited by: The acute toxicity of insecticides to fish which mean toxicity rate was determined after 96 hours and this concentration dependent, (slightly toxic with ppm), (Moderately toxic with 1.
Additionally toxicity of fish tolerance to weedicides varies with their size and species as well as plankton species, meanwhile residual chemicals can be transferred from fishes to humans when. insecticides worldwide. Toxicity and impact of Dichlorvos, an organophosphate pesticide polluting aquatic ecosystems as a potential toxicant was reviewed.
This article summarized the LC 50 values of dichlorvos to various fish species and significant findings pertaining to its lethal and sublethal toxic effects in variousFile Size: KB.

Static bioassays were used for toxicity testing. The experimental concentrations of the commercial herbicides were more high than the. to six species of freshwater crusta ceans.
These animals were selected for bioassays because they represent an important link in the food chain of fish, because little is known about toxicity of herbicides to aquatic in vertebrates, and because they were readily available and easily held or reared under laboratory conditions.
Materials and Methods. Spraying herbicides can also reduce reproductive success of fish and aquatic animals. The shallow, weedy nursery areas for many fish species provide abundant food and shelter for young fish.
Spraying herbicides near weedy nurseries can reduce the amount of cover and shelter that young fish need in order to hide from predators and to feed. Freshwater Fish Acute Toxicity test uses both a cold water (e.g., rainbow trout) and warm water (e.g., bluegill) species.
It usually lasts 96 hours and is designed to determine the concentration in water required to cause 50% lethality (LC50) in a test population of fish. (OSCPP ). EPA/ March ACUTE TOXICITY OF SELECTED TOXICANTS TO SIX SPECIES OF,FISH Rick D.

There have been relatively few investigations on the effect of herbicides on plankton. Despite decades of agricultural and urban use of fungicides and widespread detection of these pesticides in surface waters, relatively few data are available on the effects of fungicides on fish and invertebrates in the aquatic environment.
Nine fungicides are reviewed in this report: azoxystrobin, boscalid, chlorothalonil, fludioxonil, myclobutanil, fenarimol, pyraclostrobin. Surfactant Toxicity to Fish •LD 50 for nonionic surfactants (such as X and R) range from 4 to 12 ppm for fish, and from 1 to 16 ppm for aquatic invertebrates –LI has an LD 50 from to ppm for both types of organisms •Worst case scenario (aquatic application in water 1 foot deep at maximum applicationFile Size: 1MB.

Given their toxicological, environmental but also agricultural relevance, herbicides are an interesting field of activity not only for scientists working in the field of agriculture.
