Environmental and toxicological characteristics of formulated pesticides may substantially differ from those of their active ingredients or other components alone. This phenomenon is demonstrated in the case of the herbicide active ingredient glyphosate. Due to its extensive application, this active ingredient was found in surface and ground water samples collected in Békés County, Hungary, in ...

OBJECTIVES AND METHODS Searching for potent plant larvicides, crude aqueous extract of the latex of Uschar (Calotropis procera) and Labakh (Ficus benghalensis) were tested against the fourth instar larvae of the lymphatic filariasis vector Culex quinquefasciatus (Diptera: Culicidae) using the conventional methods recommended by the WHO. Likewise, the toxicity level of Malathion was tested. The ...

Farmers have increased the production of food by using chemical substances such as diuron; however, these components affect water quality and species found in ecosystems. Macrobrachium acanthurus M. olfersii postlarvae present estuary Río Jamapa, Veracruz were collected to measure LC50 LD50 herbicide Karmex (diuron: (3-(3,4-dichlorophenyl)-1,1-dimethylurea [DCMU]). The captures prawns made with...

The acute toxicity of sulfate to Ceriodaphnia dubia, Chironomus tentans, Hyalella azteca, and Sphaerium simile was assessed to support potential updates of Illinois (USA) sulfate criteria for the protection of aquatic life. The mean lethal concentrations to 50% of a sample population (LC50s), expressed as mg S04(-2)/L, in moderately hard reconstituted water (MHRW) were as follows: 512 mg/L for ...

teucrium polium l. (tp) is widely used in traditional medicine of many countries including iran. there are various reports about pharmacological properties of tp such as calcium antagonist, anti- ulcer, anti – diabetic. there are a few reports about possible toxicological effects of this plant. in the present study we designed to evaluate the subchronic toxicity of teucrium polium total extract...

objective(s) ocimum basilicum l. is widely used in folk medicine of many countries including iran. both o. basilicum and its oil extract have received considerable attention for their potential medicinal properties, but there are a few reports about possible toxicity of this plant. therefore, in the present study, acute and subchronic toxicity of o. basilicum hydroalcohlic extract have been eva...

We studied the acute toxicity of a raw effluent from a battery manufacturing plant (Pilcam) in Douala, Cameroon, to a freshwater fish (Oreochromis niloticus), and subsequently evaluated its sub-acute effects on water quality and the biota in freshwater microscosms. The acute toxicity test was based on 96 hrs static renewal bioassays that resulted in 96-h LC50 and LC90 values of 16 and 20.7% (v/...

The present investigation focused on the toxicity test of cadmium (Cd), copper (Cu), nickel (Ni), lead (Pb) and zinc (Zn), utilizing two groups juvenile adult apple snail Pomacea insularum (Gastropod, Thiaridae) with mortality as endpoint. For snails, median lethal concentrations (LC50) values based 48 72 h decreased in following order: Cu < Ni Pb Cd Zn. LC50 mussel was more susceptible to t...

The organophosphorus pesticide Phenthoate is one of the most widely used insecticide in agriculture sector to control the varieties of pests and ectoparasites. The acute toxicity bioassay tests were conducted at various concentrations ranging from 0.4 and 4.0 mg/l with an interval of 0.4 mg/l on Indian major carp Labeo rohita for 24, 48, 72 and 96 h. The acute toxicity values were determined as...

Aflatoxin B1 (AFB1) and T-2 toxin (T-2) are important food-borne mycotoxins that have been implicated in human health and as potential biochemical weapons threats. In this study the acute and combinative toxicity of AFB1 and T-2 were tested in F-344 rats, mosquitofish (Gambusia affinis), immortalized human hepatoma cells (HepG2) and human bronchial epithelial cells (BEAS-2B). Preliminary experi...
