A Study of the Impact of Municipal Solid Waste on …
Discharging of untreated municipal solid wastes (MSWs) onto land is very widespread in developing countries. The compounds contained in MSW cause a harmful effect to human and environment. Hence, an assessment of the extent of their local impact is of great interest to figure out the pollution they cause. Therefore, this study aimed at evaluating the effects of discharge of solid wastes on
D-(+)-Gluco,5-lactone (Gluconic acid lactone
D-(+)-Gluco,5-lactone is commonly found in honey, fruit juices, personal lubricants, and wine. D-(+)-Gluco,5-lactone is neutral, but hydrolyses in water to gluconic acid which is acidic, adding a tangy taste to foods, though it has roughly a third of the sourness of citric acid.
