This research was done to investigate the adsorption effect of multiwall carbon nanotubes (MWNTs) and nano Zn-oxide on decreasing chromium (Cr) and cadmium (Cd) concentration in wheat inoculated with Piriformospora indica (P.indica) that irrigated with wastewater of plating industry. Treatments were consist of applying MWCNs (0 and 0.5 % (W/W)) and nano Zn-oxide (0 and 1.5 % (W/W)) in the soil irrigated with the wastewater of plating industry under wheat inoculated with P.indica. This research was done as a factorial experiment in the layout of completely randomized block design in three replication After 90 days, plants were harvested and plant Cd and Cr were measured using atomic absorption spectroscopy. Using MWCNs had significant effect on increasing cation exchangeable capacity of soil. Applying 0.5 % (W/W) MWCNs in the soil irrigated with waste water significantly decreased the soil Cd concentration by 11.7%, while the plant biomass was increased by 13.4%. In addition, applying 1.5 % (W/W) nano Zn-oxide significantly decreased the negative effect of heavy metal toxicity that can be related to the role of nano Zn-oxide on increasing soil sorption properties. However, the interaction effect of Zn and Cd cannot be ignored. The results of this study showed that applying MWCNs and nano Zn-oxide has a significant effect on decreasing phytoremediation efficiency in soil irrigated with wastewater of plating industries. However, the type and the amount of heavy metals in wastewater cannot be ignored.","PeriodicalId":8672,"journal":{"name":"Avicenna Journal of Environmental Health Engineering","volume":"7 1","pages":"20-28"},"PeriodicalIF":0.0,"publicationDate":"2020-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47713612","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The adsorbents used were characterized using techniques like scanning electron microscope (SEM), as well as Fourier transform infrared spectroscopy (FTIR). In this study, the effects of a few key variables including pH, reaction time, dye concentration, adsorbent dosage and temperature on the adsorption performance were investigated. Optimum values were attained at 0.04 and 0.08 g doses of modified and raw cantaloupe peel, pH of 7 after mixing for 120 and 90 minutes for raw and modified cantaloupe peel, respectively. The equilibrium information was fitted to the Langmuir, Freundlich, Temkin, and Dubinin-Radushkevich equations and the respective data for all models were tested. An increase in adsorbent dose and temperature caused the efficiency to rise. The mechanism and rate of adsorption were ascertained by analyzing the experimental data at various contact times according to traditional kinetic equations: pseudo-first-order and second order, Elovich, and intra-particle diffusion. The findings illustrated that the data accorded closely with the pseudo-second-order model. Moreover, it was found that these wastes can be applied to remove environmental pollutants, particularly methylene blue dye.","PeriodicalId":8672,"journal":{"name":"Avicenna Journal of Environmental Health Engineering","volume":"7 1","pages":"35-46"},"PeriodicalIF":0.0,"publicationDate":"2020-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49449935","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

According to WHO reports, the COVID-19 outbreak is likely to last between 18 and 24 months. In this situation, long-term use of chemical disinfectants, especially chlorinated substances and detergents, in addition to causing harmful effects on human health, can pose a threat to the environment, water, and soil resources. Due to their high efficiency, availability, and affordability, the chlorinated compounds are commonly used as the most important disinfectant in preventing the spread of infectious disease. These compounds have a highly toxic effect on the airways and cause short-term and long-term pulmonary complications. Acute and severe exposure to chlorine gas, especially indoors, can lead to acute and severe shortness of breath, airway spasm, wheezing, and pulmonary embolism. These complications are so severe in some cases that can lead to hospitalization. Long-term complications are also observed such as chronic asthma which may require long-term treatment (5,6). Hence, it seems necessary to provide an effective protocol for disinfection for a long time, which poses a low risk to the environment and to human health. In this regard, the use of disinfectants effective against the SARS-Cov-2 virus with less toxic effects can be a good alternative. Accordingly, it is necessary to pay attention to the following points: • Engineering controls should be considered for decreasing the adverse health effects of frequent use of disinfectants including ventilation and isolation. Therefore, proper ventilation of indoor air in hospitals can prevent overexposure of health care staff and patients with the used disinfectants. Moreover, isolation can be an effective method in engineering control, in which disinfection can mainly be performed in a shift when fewer health care stuff are exposed (7).

In addition, due to the dissolution of these nano-materials, some of the adverse effects could result from the dissolved metals. On the other hand, dietary supplements play a key role in improving the immunity of consumers; hence, the use of immune stimulants such as mushroom seems to be very necessary. In this study, the dietary effect of Pleurotus ostreatus mushroom was investigated on serum immunity and liver histopathological indices of Oreochromis niloticus exposed to silver nanoparticles (AgNPs). Serum total protein level enhanced with increasing prebiotic concentration. Serum immunoglobulin and albumin levels increased in the group treated with Pleurotus ostreatus. The amount of these indices significantly increased at the concentration of 0.2 mg/kg; however, glucose value decreased in both of the experimental groups. Serum ALT and ALP levels significantly reduced in the combined treatment group (AgNPs and mushroom) at the concentration of 0.2 mg/kg, in contrast with the control group. In the combination treatment group (AgNPs and mushroom), the serum AST level significantly reduced at concentrations of 0.1 mg/kg and 0.2 mg/kg; however, it increased at the concentration of 0.05 mg/kg compared with the control group, indicating that immunological indices could improve due to the combined use of AgNPs and mushroom.

Despite the great importance and existence of polluted resources in the vicinity of vineyards in Malayer, there are few studies conducted in this regard. To evaluate the pollution level of toxic elements in these vineyards, 20 sampling stations were selected randomly and samples of garden soil and leaves of grapevine species were collected. After the acidic digestion of the samples, the concentrations of the heavy metals were measured using atomic absorption spectrometer. Then, the indices of contamination factor (Cf), geoaccumulation index (Igeo), biological accumulation coefficient (BAC), and ecological risk index (RI) were calculated. According to the results obtained for Igeo and Cf indices, the soil in the study region was moderately contaminated with copper. However, the ecological risk index and BAC of the studied region were low. To investigate the spatial distribution of copper in the studied region, the spatial distribution map was prepared. To locate the source of copper contamination and investigate the effect of various land uses on the amount of contamination, land use map (LUM) of vineyards was generated. To this end, images were downloaded from Landsat Satellite, and after the exertion of various corrections on the images based on the supervised classification method, the LUM with agricultural, residential, vineyard, brick furnace and pasture classes was prepared. The comparison of the LUM and the copper contamination map illustrated that the copper contamination was higher in the places with urban and adobe furnace land-use types.","PeriodicalId":8672,"journal":{"name":"Avicenna Journal of Environmental Health Engineering","volume":"6 1","pages":"83-91"},"PeriodicalIF":0.0,"publicationDate":"2019-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42624627","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
