It is estimated that the use consumption of tobacco in diverse forms leading to is one of the important causative factors of avoidable yet ever increasing cancer death burden globally every year, with a majority occurring in Asia. Owing to the considerable difference in the patterns of usage of various categories of smokeless tobacco products (STP), it is possible that a broad range of toxicant content exposure among STP users. Habitual consumption of tuibur, a peculiar form of tobacco smoke infused saturated aqueous solution is presumed as one of the “safe” nicotine delivery medium. When commercially Commercially available tuibur sample was collected and subjected to the vibrational spectral study, it has revealed the molecular vibrational frequencies corresponding to various functional groups of different chemical constituents present in tuibur.
Intensive jhum cultivation is the biggest ecological threat due to its associated problems such as biodiversity loss, deforestation, soil erosion and the gradual reduction of land productivity in Mizoram. The intrinsic practice of jhum cultivation still dominated the farming system in Mizoram to a large margin. Four levels of nitrogen, phosphorus and potassium soil fertilizer application in local maize variety was conducted in 2 years, 3 years and 5 years jhum cycles. Strong significant (P<0.05) response to fertilizer application occurred in the growth and yield performance of maize. Different period of jhum cycles also had significant (P<0.05) effect in growth and yield with highest productivity in longest jhum cycle. Taking account of the poor soil nutrient content and the acidic soil in Mizoram, application of urea at lower rate under longer jhum cycle may be adopted.
cigarette filter during smoking, while it gets settled during the manufacture of tuibur. The particulate phase of tobacco smoke contains mainly relatively non-polar organic substances that are described as semivolatile and non-volatile constituents. Identification of toxic and carcinogenic compounds present in smokeless tobacco products such as tuibur is a preliminary step in assessing adverse effects associated with its consumption. Characterization of the molecular vibrational frequencies of various semivolatile and non-volatile chemical components associated with the tar phase of tuibur was performed using FTIR spectroscopy to ascertain these organic components.
Arsenic is a naturally occurring element found primarily in rocks, soil, water, and plants in the Indian sub-continent. Natural events, such as infiltration to water, dissolution of minerals from clay, and erosion of rocks, can release arsenic into water. Arsenic is usually found in inorganic forms in water, the most predominant form being arsenate [As (V)], with arsenite [As (III)] under some conditions. In organism, it bonds with carbon and hydrogen, forming organic arsenic. The contamination of groundwater by arsenic in Chawngte, Mizoram, India is likely to happen due to its sharing of a common land border with Bangladesh. Groundwater and rainwater are the most important supplementary sources of drinking water in region. Hence, residents of Chawngte are relying on tuikhurs (spring) and other natural sources. It has been observed that several number of tube wells, tuikhurs and hand pumps, exist in any cluster or community. Generally, not all tube wells and hand pumps in an area are affected by arsenic. Therefore, the immediate challenge is to find out the unaffected ones in the affected areas and commence routine monitoring in order to stop using the currently affected tube wells as soon as arsenic is detected. The physico-chemical parameters like pH, EC, TDS, total hardness, total chlorides, iron and free chlorine are well within the acceptable limits for drinking water. Arsenic and turbidity are slightly higher than the acceptable limits but still within the permissible limit of 0.05 mg/l and 5 NTU respectively.
