“…The National Nutrition and Food Research Institute of Iran estimated the average consumption of edible vegetables is 218 g/person/day. While, the average adult and child body weights were considered to be 55.9 and 32.7 kg, respectively [15] , [16] . The daily intake of metals was estimated according to the average vegetable consumption for both adults and children ( Table 2 ).…”

Food safety is a major problem currently facing the world and food consumption has been identified as the major pathway for human exposure to hazardous pollutants such as heavy metals. These datasets include the concentration of heavy metals like Cd, Pb, Cu, Ba, Co and Sn in selected vegetables in Guilan province and estimate daily intake of metals. The results of this dataset showed that the average concentration of heavy metals including Cd, Pb, Cu, Ba, Co and Sn in total vegetables were 0.55, 1.098, 4.095, 5.98, 0.69, and 0.2 mg/kg, respectively. The mint showed higher levels of Pb, Cu and Co contamination compared to other vegetables. The estimated daily intakes of Cd, Pb, Cu, Ba, Co and Sn for children were 0.311, 0.622, 2.320, 3.388, 0.391, 0.119 µg/day, whereas for adults were 0.182, 0.363, 1.357, 1.98, 0.228, 0.069 mg/kg, respectively. The present data highlights that both adults and children consuming vegetables ingest significant amount of these metals.

“…Chromium pollution primarily originates from several industrial processes, such as stainless steel, electroplating, pigment, and chemical production, ceramic and leather tanning processes (Naddafi and Saeedi, ; Agarwal et al , ; Kamani et al , ; Fazlzadeh, Rahmani et al , ). One of the main problems with these pollutants is related to the characteristics of bio collection in liver, causing kidney syndromes and death at high density of 0.1 mg/L in addition to high toxicity (Jafari et al , ; Jaafari et al , ; Moradi et al , ; Hassani et al , ; Moradi, Mansouri et al , ; Jaafari et al , ; Mesdaghinia et al , ). There are many reports on different techniques of purification, such as ion exchange, reverse osmosis, electrolyte absorption, chemical deposition, membrane filtration and solvent extraction for removing Cr(VI) from water and waste.…”

This paper investigates the removal of Cr(VI) and NH4+ from aqueous solutions using greensand (glauconite). The effects of adsorbent dosage, contact time, initial Cr(VI) and NH4+ concentrations, and pH were investigated in batch experiments. The results show that these parameters influenced Cr(VI) and NH4+ removal using glauconite considerably. Pseudo‐first‐order, pseudo‐second‐order and intraparticle diffusion kinetic models were applied to explain the kinetic data, and the pseudo‐second‐order model achieved good agreement. The equilibrium isotherm data are coordinated with the Freundlich, Langmuir models, Temkin and Dubinin–Radushkevich; the Freundlich model proved most best suitable. The removal efficiency of Cr(VI) and NH4+ were 12.21 mg/g (54% at pH 3) and 19.24 mg/g (77.08% at pH 7). All in all, the results showed that the adsorption process on glauconite could be used as an effective method for removing Cr(VI) and NH4+ from aqueous solutions.

“…But continuous monitoring of industrial waste water quality and effluent treatment plants (ETP) is necessary to prevent the risk of surface water pollution. The use of conventional waste water treatment process becomes increasingly challenged and advanced technologies such as anaerobic fluidized bed reactor, aerobic moving bed reactor can be used for the treatment of highly contaminated water [25][26][27][28][29] . The objective of the present research was to characterize industrial effluents from six ready made garments industries of Gazipur, Savar and Narayanganj areas and assess the contamination potential.…”

Textile manufacturing sector is the strongest root of the economy of Bangladesh while pollution by inappropriate management of waste water from textile dyeing industries is one of the major environmental problems. Textile processing employs an assortment of chemicals, contingent upon the idea of the crude materials and items. Environmental problems caused by the the textile industry are mainly the discharges of waste water. The wellspring of waste water contamination are the wet handling steps which incorporate measuring, desizing, scouring, bleaching, mercerizing, coloring, printing etc. The present study was aimed at physico-chemical evaluation of waste water discharged by some garments industries. While in some waste water high pH values have been recorded, the pH values of the waste water before and after treatments were found in between the standard range. The Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Dissolved Solid (TDS) and Total Suspended Solid (TSS) values for waste water before treatment were found to be much higher than the permissible limits. For some industries the BOD, COD, TDS and TSS values of the outlet water from effluent treatment plant (ETP) were also found beyond the standard limits.
