The dried tobacco waste was mixed in proportions of 1%, 2% and 3% in soil and filled in earthen pots of 6 kg capacity. Three replicate pots for each soil concentration were used. Tomato saplings of cultivar Bezosheetal were transplanted age of 20 days (signifying stage before flowering), 25 days (signifying stage at the start of flowering) and 45 day (signifying just at the onset of fruiting). The morphological parameters like plant height, number of leaf, flower plant(-1), number of fruits and yield plant(-1) were recorded. Nutrient parameters like moisture, total soluble solids (TSS), acidity vitamin C, reducing sugar proteins, pectin and lycopene were analyzed in tomato fruits. Experiments revealed that the yield of tomato fruit and critical nutritional parameters showed significant increase. For higher yield (183 g plant(-1)) of tomato, the best option is the use of 3% tobacco waste after 45 days of transplant. Alternatively, use of 2% tobacco waste with 45 days of transplant provides a higher quality tomato. The yield obtained here would be significantly higher than control but not as high as with 3% tobacco waste.

Cigarette butts are classified as plastic waste due to their composition of cellulose acetate fibers and are commonly found in beach sand. Their persistence in the environment, low biodegradability, and potential to interact with metals and metalloids during the aging process make them a significant subject of interest for research on coastal marine ecosystems. The aim of this study is to investigate the presence of metals such as hexavalent chromium Cr (VI), cadmium (Cd), and the metalloid arsenic (As) in cigarette butts (CBs), cigarette butt fibers (CBFs), and sand on a tourist beach in Cartagena, Colombia.

Originally native to South America, tobacco and is now distributed worldwide as a major cash crop. Nicotine is the main harmful component of tobacco leaves, cigarette smoke and tobacco waste, which severely affects not only the flavor of the tobacco leaf, but also causes great damage to human health. As the anti-smoking movement continued to grow since the 1950s, and consumers become more aware of their health and environmental protection, the world tobacco industry has been committed to research, develop and produce low nicotine cigarette products with relatively low risk to human health.

The increase in maritime traffic has led to substantial greywater discharges into the marine environment. Greywater, originating from sinks, showers, kitchen, and laundry facilities, contains a wide array of chemical contaminants influenced by on-board activities, ship size, and management practices. The lack of comprehensive regulations for greywater management, along with limited research on its chemical composition, highlights the need to characterize these waste streams.

Discarded cigarette butts (CBs) are a significant source of environmental pollution. In areas with large amounts of cigarette waste, environmental hazards may arise due to the leaching of chemicals from filters and smoked tobacco. Accurately estimating the number of CBs on beaches requires a standardized method.

Discarded cigarette waste may leach toxic elements and can contaminate different environments. In this study, the levels of organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs) in cigarette butts (CBs) leachates were determined, and the release rate of these pollutants from three CBs types such as smoked CBs with and without tobacco (SCBs and SFs) and unsmoked filters (USFs) were examined. The mean concentration levels of PCBs compounds were
