Although the effects of acute pesticide poisoning are well known for the pesticides most currently used, hardly any data exist on health effects after long-term low-dose exposures. Major unresolved issues include the effect of moderate exposure in the absence of poisoning. The increased utilization of pesticides other than organophosphates makes it even more difficult to find associations. In t...
Acute organo-phosphorus pesticide poisoning, oxidative damage, haemoglobin level and total leukocyte
Isolation and characterization of organ phosphorus pesticide degrading bacteria from different crops
The effects of pesticide application on the diversity culturable bacteria in soil corn farmland Sanjiang Plain were studied, and capable degrading acetochloramine samples screened. In black where “ethyldiazine 86” was applied, experimental group control set, two groups cultured screened by coating plate method. 16S rRNA gene sequences morphological characteristics analyzed to determine species ...
BACKGROUND The health benefits of organic foods are unclear. PURPOSE To review evidence comparing the health effects of organic and conventional foods. DATA SOURCES MEDLINE (January 1966 to May 2011), EMBASE, CAB Direct, Agricola, TOXNET, Cochrane Library (January 1966 to May 2009), and bibliographies of retrieved articles.

In order to assess the effects of different pesticides on nutrient levels of rice, three pesticides (Diazinon, Tricyclazole and Butachlor) which are commonly used in paddy fields in Iran were selected in a randomized complete block with 3 replicates in field condition. The result indicated that the impact of different pesticides on total protein and nitrogen, phosphorus and potassium ...
The literature of pesticide residue analysis is reviewed selectively for the period 1999-2000. Analyses of a wide range of pesticide classes and sample types, as well as some related organic pollutants, are covered. Studies of exposure and monitoring as well as pesticide degradation, persistance, leaching, mobility, and metabolism studies are included.
Chronic Exposure to Pesticides- Neurological, Neurobehavioral and Molecular Targets of Neurotoxicity
There is an increasing concern regarding the widespread use of pesticides and their potential impacts on public health. Pesticides differ from other chemical substances because they are toxic chemicals deliberately spread into the environment with the aim of controlling undesired living species. Since their toxicity may not be completely specific for the target organisms, their use may pose a r...
Residues of the herbicides simazine, metribuzin, metolachlor, trifluralin, atrazine, and two metabolites of atrazine, deisopropylatrazine (DIA) and deethylatrazine (DEA), are surveyed in the surface and groundwater of the Primavera do Leste region, Mato Grosso, Brazil during September and December 1998 and April 1999. Different water source sampling stations of groundwater (irrigation water wel...
