Hence, we aimed to determine the presence of lead and mercury in selected soaps commonly used in Mashhad, northeastern Iran. Methods: Different common brands of cosmetic, hygiene and contraband soaps were purchased from retail market of Mashhad in 2016. Levels of these metals were determined using atomic absorption spectroscopy technique. Results: All samples had the mercury and lead levels but did not exceed the maximum acceptable level (1 µg/g for mercury and 20 µg/g for lead) recommended by FDA. The mean levels of mercury were 0.02, 0.08 and 0.23 µg/g, respectively in cosmetic, hygiene and contraband soaps. These levels for lead were 0.10, 0.19 and 0.13 µg/g. The highest mercury and lead levels were detected in Halazoon contraband and P hygiene brands, respectively. Conclusion: The content of mercury and lead in common soaps is currently not a concern in this city. However, as human body may be exposed to several toxic metals from different care products simultaneously, cumulative toxic effects of these metals must be considered important.}, Keywords = {Atomic Absorption Spectroscopy, Iran, Lead, Mercury, Soap}, volume = {11}, Number = {4}, pages = {1-3}, publisher = {Arak University of Medical Sciences}, doi = {10.29252/arakmu.11.4.1}, url = {http://ijt.arakmu.ac.ir/article-1-598-en.html}, eprint = {http://ijt.arakmu.ac.ir/article-1-598-en.pdf}, journal = {Iranian Journal of Toxicology}, issn = {2008-2967}, eissn = {2251-9459}, year = {2017} } @article{ author = {Evaz-ZadehSamani, Hamid and Banaee, Mahdi and Shoukat, Parvaneh and Noori, Ahmad and MousaviDehmoredi, Laleh}, title = {Protective Effects of Dietary Spirulina platensis against Cadmium-Induced Oxidative Stress in Gills of Rainbow Trout}, abstract ={Background: Contamination of feeds with cadmium leads to oxidative stress in vital tissues such as gills and affects the fish survival. Therefore, an increase in the capacity of the antioxidant defense system and detoxification system of fish may reduce adverse effects of pollutants. This study investigated the protective effects of microalga Spirulina platensis against oxidative stress in gills of cadmium-treated rainbow trout. Methods: This study was conducted at Fish Farm, Almas-Dime Village, Koohrang, Charmahal & Bakhtiari Province, Iran from April to July 2016. Rainbow trout were allocated into five groups of which one group received normal feed and served as control. Fish from group II received 0.2 mg CdCl2 per 1 kg feed. Groups III-V were fed with enriched diet with 2.5, 5 and 10 g S. platensis per 1 kg feed, respectively and simultaneously treated with 0.2 mg kg-1 CdCl2 for 21 d. Changes in biochemical parameters including alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP) and lactate dehydrogenase (LDH), malondialdehyde (MDA) as marker of lipid peroxidation and cellular total antioxidant capacity were evaluated. Results: Oral exposure to CdCl2 caused a significant increase in MDA levels and altered AST, ALT, ALP and LDH activities in gills (P<0.05). The cellular antioxidant capacity was significantly lowered in CdCl2-treated fish as compared to the control group (P<0.05). Oral administration of S. platensis significantly ameliorated these changes in certain biochemical parameters in gills of CdCl2-treated fish. Conclusion: The findings indicate that S. platensis has protective effects against toxic influence of CdCl2 on certain biochemical parameters in gills of fish.}, Keywords = {Biochemical Parameter, Cadmium, Microalga, Oxidative Stress}, volume = {11}, Number = {4}, pages = {5-12}, publisher = {Arak University of Medical Sciences}, doi = {10.29252/arakmu.11.4.5}, url = {http://ijt.arakmu.ac.ir/article-1-590-en.html}, eprint = {http://ijt.arakmu.ac.ir/article-1-590-en.pdf}, journal = {Iranian Journal of Toxicology}, issn = {2008-2967}, eissn = {2251-9459}, year = {2017} } @article{ author = {Hedayati, Aliakbar and Darabitabar, Fatemeh and Tarkhani, Rez}, title = {Toxic Response of Mosquito Culex Quinquefasciatus (Diptera: Culicidae) to some Agricultural Pesticides (Butachlor and Pertilachlor)}, abstract ={Background: The expansion of herbicide used in aquatic ecosystems as well as in terrestrial if is not properly controlled may produce harmful effects on freshwater fisheries. Residue limits of these agricultural chemicals in tropical fishery waters should be established. The aim of this study was to determine the acute toxicity of butachlor and pertilachlor as potential dangerous herbicides to assess mortality effects of these chemicals to the Mosquito Culex quinquefasciatus. Methods: This study was carried out in Gorgan University of Agricultural Sciences and Natural Resources, Gorgan, Iran at summer 2013. Culex samples were exposed to different concentrations of butachlor and pertilachlor (0-200ppm for butachlor and pertilachlor) for 96 h. Results: The low toxicity of LC50s obtained for butachlor (23.81±0.04) and pertilachlor (27.97±0.05) indicate that butachlor and pertilachlor were lowly toxic to Mosquito Cu. quinquefasciatus.

In this study, one of the major center of cucumber cultivation at south west of Iran, Darreh shahr City in Ilam Province were studied for non-authorized pesticides usage, which health authorities and national standard organization do not recommend. Methods: A reliable, rapid and accurate method based on spiked calibration curves and modified QuEChERS sample preparation was developed for determination of 7 non-authorized pesticides. During 2014 fifty cucumber samples were collected and analyzed by gas chromatography Electron Capture Detector (GC/ECD). For overcoming matrix effects, calibration curve was prepared by spiked samples. Results: Method was validated with related parameters. The recovery of pesticides at five concentration levels (n=3) was in the range of 81.02-91.66%. The method was proved repeatable with RSD lower than 20%. The limits of quantification for all pesticides were 10 ng/g. Conclusion: There are some pesticides which are legally used with identified MRL in cucumber, but for better protection farmers used another pesticides which are not permitted by health authorities, consequently are harmful for consumers.
