“…During tobacco processing and manufacturing tobacco products, nicotine which is a water soluble compound is transferred to the aqueous solution of the waste water [ 63 ]. Also tobacco dust with high content of nicotine can accumulate and nicotine can be extracted to ground waters [ 64 ]. In addition, the production of nicotine-based pharmaceuticals is another source of this substance that can arrive in municipal wastewater systems [ 65 , 66 ].…”

Pollution of drinking water sources represents a continuously emerging problem in global environmental protection. Novel techniques for real-time monitoring of water quality, capable of the detection of unanticipated toxic and bioactive substances, are urgently needed. In this study, the applicability of a cell-based sensor system using selected eukaryotic cell lines for the detection of aquatic pollutants is shown. Readout parameters of the cells were the acidification (metabolism), oxygen consumption (respiration) and impedance (morphology) of the cells. A variety of potential cytotoxic classes of substances (heavy metals, pharmaceuticals, neurotoxins, waste water) was tested with monolayers of L6 cells (rat myoblasts). The cytotoxicity or cellular effects induced by inorganic ions (Ni2+ and Cu2+) can be detected with the metabolic parameters acidification and respiration down to 0.5 mg/L, whereas the detection limit for other substances like nicotine and acetaminophen are rather high, in the range of 0.1 mg/L and 100 mg/L. In a close to application model a real waste water sample shows detectable signals, indicating the existence of cytotoxic substances. The results support the paradigm change from single substance detection to the monitoring of overall toxicity.

“…Nicotine can be used as a laboratory reagent, as a precursor for nicotinic acid, also known as the B3 vitamin [29] or as organic pesticide [30]. Nicotine can also be applied in nicotine patch, as an aid to quit smoking [31].…”

“…Nicotine is considered to be one of the alkaloids and it's a highly toxic substance whereas its fatal dose reaches to 40-60 mg/kg. Besides, nicotine is more toxic than many other alkaloids such as cocaine which has a fatal dose of 1000 mg/kg [1], Nicotine is an organic compound -3 (-1 methyl -2 -pyrrolidinyl) pyridine [2], because nicotine is soluble in water, it causes environmental pollution where large amounts of nicotine moves to the wastewater that produced by tobacco's treatment operation and its industrial products, that's how it moves to the groundwater and contaminates it [3], therefore, these wastes, which constitutes a serious threat to the environment and human health, have been classified to be toxic and hazardous substances according to the instructions of the European Union [4], On the other hand, nicotine has recently manifested some benefits to treat certain nerve diseases despite some concerns about it. This issue has imposed the need not only to separate nicotine and extract it but also to retrieve the adsorption capacity of lead in the aqueous solutions was 75.95 mg.g -1 [8].…”

The Adsorption Of Nicotine On Calcinated And Modified Compressed Coffee Residue And Its Surface Properties

A DRIED compressed coffee residue was calcinated at a temperature of 400 0 C for 4 hours.It was analyzed quantitatively and qualitatively by using X-Ray Fluorescence (XRF) spectroscopy. The coffee carbon surface was modified with oleum. The surface properties of the sample were studied by using the FTIR spectroscopy after each treatment resulting new different peaks that indicate the modification with oleum. Besides, other peaks that indicate the adsorption of nicotine on its surface were obvious. The concentrations of nicotine in the studied solutions were measured by using the spectrophotometry, the nicotine adsorption on the studied adsorbent followed the pseudo second-order model. The effect of nicotine concentration was also studied at the temperatures of 20-30-35-40 0 C; an increase of the nicotine adsorption was noticed with the increase of the initial concentration at each of the studied temperatures; the adsorption curves fitted the Langmuir and Freundlich isotherms models. In addition, the thermodynamic parameters of the surface adsorption interaction ∆G 0 , ∆H 0 , ∆S 0 were determined, the resulting values showed that the interaction is endothermic and the adsorption is of chemical nature. Besides, a mechanism for the adsorption of nicotine on modified compressed coffee residue carbon (CACS) was suggested presuming the participation of the two nitrogen atoms in the polar nicotine molecule.
