The objective of this study was to explore the antioxidant levels and anticancer properties of chicory cultivated using three different kinds of fertilizers (i.e., developed, organic, and chemical) in the presence and absence of pesticides. Phenolic phytochemicals, including total polyphenols and flavonoids, and antioxidant activities, including reducing power, ABTS+ and DPPH radical scavenging...

Polar organic chemical integrative samplers (POCIS) are useful for monitoring a wide range of chemicals, including polar pesticides, in water bodies. However, few calibration data are available, which limits the use of these samplers for time-weighted average concentration measurements in an aquatic medium. This work deals with the laboratory calibration of the pharmaceutical configuration of a...

An analytical method was developed to determine pesticides of various chemical classes in soil, juice and honey using analyte protectants to counteract the enhancement of the chromatographic response produced by the presence of matrix components (matrix effect). This effect was more pronounced for soil and honey samples than for juice samples; regarding the pesticide chemical class, organochlor...

Natural toxins are a source of new chemical classes of pesticides, as well as environmentally and toxicologically safer molecules than many of the currently used pesticides. Furthermore, they often have molecular target sites that are not exploited by currently marketed pesticides. There are highly successful products based on natural compounds in the major pesticide classes. These include the ...

For the first time, a multi-residue methodfor simultaneous determination of 41LC-amenable pesticides in rice, belonging to different chemical classes has been developed in Iran by LC-MS/MS. The pesticides were analyzed simultaneously in a single run using positive electrospray ionization with multiple reaction monitoring (MRM) after extraction with slightly modified QuEChERS method. The calibra...

the purpose of this study is the analysis of the farmers economic behavior to reduce the adverse environmental effects of agricultural chemical inputs by using contingent valuation approach and tobit model by heckman's two stage. to achieve the desired goal, 100 questionnaires collected by a random sampling from farmers of kashaf- rood basin in mashhad city in 2013. results showed that variable...

Abstract Pesticides are agrochemical used to increase agronomic production and higher economic profit. However, these chemical pesticides could be persistent in soil and water, collective in silt or bio-aggregates in biota relying upon their dissolvability, prompting various kinds of natural contamination. These pesticides have also shown detrimental effects such as phytotoxicity, genotox...

The purpose of this study was to investigate the nuclear magnetic resonance (NMR) assignments of hydrolyzed products extracted from human blood plasma. The correlations between chemical, functional and structural properties of highly toxic pesticides were investigated using the PreADME analysis. We observed that toxic pesticides possessed higher molecular weight and, more hydrogen bond donors a...
