“…The people which were worked with chemicals such as VOCs, toxic heavy metals, and toxic gases (H2S) must be determined in biological matrixes and considered as an important feature in the HSE-MS system. So, evaluation and determination of this pollution in workers, waters and gases with analytical technique (Bagheri Hosseinabadi et al, 2019; Jamshidzadeh & Shirkhanloo, 2019; Miranbeigi et al, 2018; Mirzahosseini, 2019; Pasban & Nonahal, 2018; Paydar & Faghihi Zarandi, 2019) must be done for chemical industries as the main indicators.…”

By integrated management system (IMS) based on integrated main indicators (IMI), the quality of health, safety and environmental management specifically for chemical industries was well increased. This study aimed to evaluate and compare integrated and efficient indicators in two chemical industries in Iran by health, safety, and environment (HSE) management system (MS). The integrated indicators were divided into HSE domains in the form of a questionnaire by proposed method and the weight of each of them was calculated from 101 features in the field. A list of criteria, sub-criteria, and integrated indicators was first prepared for assessing the performance of the HSE-MS system, and Delphi was finalised with the help of experts, and then the results were weighed by ANP and DEMATEL methods for two companies. Finally, 101 integrated and efficient indicators were extracted for performance evaluation to demonstrate the application of the DEMATEL, ANP method to select effective indicators in measuring HSE-MS performance in two chemical industries. In this study, the mean scores per weight of HSE indicators for chemical industries A and B increased from 2.38 to 2.79 and 1.84 to 2.056 in the beginning of 2017 up to the end of 2018. The mean score of HSE indicators for companies A and B were archived (2.65 and 2.93) and (1.95 and 2.16), respectively, in the spring/winter of 2017 and 2018. So, HSE-MS and IMS help chemical industries to improve HSE and management systems to achieve high-quality industry in different options, especially in human sources. Although in this study all trends of HSE indicator had a moderate phase with positive rate from spring 2017 up to winter 2018 for two companies A and B but company B moved slowly as compared to company A.

“…Also, Shahi Ahangar showed that the photocatalytic removal efficiency in the concentrations of 50, 100, and 300 ppm was equal to 87.8%, 98.9%, and 90.8%, respectively [10]. Many researchers used different pilot and nanoadsorbents (Ni-MWCNTs, GQDs, NGO, NG, MSN, ILs, Silica) to remove hazardous pollutants such as toluene, ethyl benzene, mercury, benzene, dust, and hydrogen sulfide from the air [4,[11][12][13][14][15][16][17][18][19][20]. Finally, according to those mentioned above and the high efficiency of nanoadsorbents compared to other adsorbents in the removal of different materials in the previous studies, a comparison study for adsorption of xylene from the air between commercial activated carbon absorbent and Nano carbon adsorbent was obtained to survey the effect of nanoadsorbent in the removal of xylene from the air.…”

As main air pollutants, volatile organic compounds (VOCs) must be paid special attention. In this study, the removal efficiency of xylene from the air was investigated by nano-activated carbons (NACs) as an efficient adsorbent and compared to commercial activated carbons (ACs). In the chamber, the xylene vapor in pure air was generated, stored in the airbag (5 Li), and moved to adsorbents. Then, the xylene vapor was absorbed on the NAC/AC adsorbents and desorbed from it by a heat accessory. The efficiency of xylene removal with NACs and ACs was investigated in the dynamic and static systems based on 100-700 mg L-1 of xylene, flow rates of 100 ml min-1, and 100 mg of adsorbent at a humidity of 32% (25°C). Xylene concentrations were determined by gas chromatography equipped with a flame ionization detector (GC-FID). In the batch system, the maximum absorption capacity for NACs and ACs was obtained at 205.2 mg g-1 and 116.8 mg g-1, respectively. The mean adsorption efficiency for NACs and ACs adsorbents was obtained at 98.5% and 76.55%, respectively. The RSD% for NACs ranged between 1.1-2.5% in optimized conditions. The characterizations of the NACs adsorbent showed that the particle-size range was between 35-100 nm.

“…In other hands, the lead absorb by gastrointestinal of children up to 50% [3]. The aerosols, metals and VOCs were studied in several fields, including epidemiology, respiratory medicine, air purification technology, and air pollution removal by different techniques and pilots [11][12][13][14]. Aerosols are further categorized on the basis of the variation in the particle size.…”

In this study, the enrichment and novel sorbent based on functionalized bimodal mesoporous silica nanoparticles (HS-UVM 7 and NH 2 -UVM 7 ) was used for removal of lead aerosols pollution from air by solid liquid gas phase extraction method (SLGPE). In bench scale set up, the lead aerosols [(Pb (NO 3 ) 2 , PbO] was generated by dispersive aerosols generator system (DAGS) and removed from air by reaction loop (RL) / impinger trap (IT) in a liquid phase which was mixed with nano adsorbent in optimized pH. The effect of parameters such as, flow rate, volume of liquid phase, time stirring, temperature, concentration, pH and amount of sorbent (mg) were studied and evaluated by flame atomic absorption spectrometry (FAAS). In optimized conditions, the adsorption capacity of HS-UVM 7 and NH 2 -UVM 7 for Pb(NO 3 ) 2 aerosols was obtained 255.6 mg g −1 and 177.6 mg g −1 , respectively which was more than UVM 7 . The lead oxides aerosols (PbO) were extracted only by HS-UVM 7 at acidic pH with the adsorption capacity of 271.2 mg g −1 . The characterization of SEM, XRD, TEM, and FTIR showed that the HS-UVM 7 has beneficial surfaces for removal of (Pb (NO 3 ) 2 and PbO aerosols from the air by SLGPE method at pH = 5. The method validation was confirmed by standard addition and NIOSH method.
