An extraction method based on matrix solid phase dispersion (MSPD) and high performance liquid chromatography with UV detection for quantification of two widely used pesticides (Malathion and α-Endosulfan) in Khazar rice from north of Iran were investigated. The ratio of solid phase (adsorbent) to sample, types of eluting solvent and its volume were optimized to achieve the highest recoveries f...

background: pistachio is one of the main nutrients, not only as a strategic crop but also as a main type of nut, in iranians’ food cycle. the aim of this study was to measure the relative safety of iranian pistachio based on the standard pesticide’s residue limits, which should be monitored and assessed in the cultivation of pistachio in order to confirm its public health. methods: fifty sample...

Management of cocoa plantation field relied on the use of pesticides over the years; hence, the fate of such chemicals is one of the most debated issues among the stakeholders. Young and old cocoa plantation fields from 4 major cocoa producing States in Nigeria were selected as the study area. Eight composites soil samples collected from 3 portions of 6 transect measured area (100 x 50m) of 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...

background: the objective of this study was to determine the residual concentrations of ethion and imidacloprid in cucumbers grown in greenhouse. the effect of some simple processing procedures on both ethion and imidacloprid residues were also studied. methods: ten active greenhouses that produce cucumber were randomly selected. ethion and imidacloprid as the most widely used pesticides were m...

BACKGROUND Chlorinated pesticides have been used in pest control for several decades in the world. These compounds are still applied in many regions, and their continuous usage has resulted in their bioaccumulation and residue in the food chain. These residues could transfer to food products and accumulate in fat tissues. Undoubtedly, the breast milk could be a significant biomarker for estimat...

Tea is an agricultural product of the leaves, leaf buds, and internodes of various cultivars and sub-varieties of the Camellia sinensis plant, processed and vulcanized using various methods. Tea is a main beverage in Iranian food basket so should be free from toxic elements such as pesticides residue. There is no data bank on the residue of pesticides in the consumed black tea in Iran. The pres...

Several Belgian beekeepers were asked to shut down their hives due to withering of the hive. The cause of the withering was unknown. A multi-factoral study was initiated, which included a multi-class pesticide residue study from honey, to determine if pesticides were the cause of the decline. The extensive distribution of pesticides causes bees that have been fed on contaminated blossoms to tra...

Background: Pistachio is one of the main nutrients, not only as a strategic crop but also as a main type of nut, in Iranians’ food cycle. The aim of this study was to measure the relative safety of Iranian pistachio based on the standard pesticide’s residue limits, which should be monitored and assessed in the cultivation of pistachio in order to confirm its public health. Method...

pesticides are widely used in iranian agriculture and this has made a major toxicological concern among health professionals. the objective of this study is to explore national data about pesticides toxicity. all relevant databases such as google scholar, pubmed, and scopus in a time period of 1960 to 2012 were searched for the keywords “pesticides, iran, environment, and population studies”. a...
