UNIT OPERATIONS IN CHEMICAL INDUSTRIES
Abstract: The unit operation like distillation, absorption, evaporation, filtration, drying, etc. are most important factors. Distillation is a purification method for liquids and can separate components of a mixture if they have significantly different boiling points. Absorption is a physical or chemical phenomenon. Evaporation can be defined as the process where liquid is transformed into a gaseous state. Evaporation can occur only when water is available. Drying is an important unit …

Use of Pesticides leads to Environmental degradation
Abstract: Pesticides are extensively used for agriculture but residues can reach aquaticecosystems, frequently. They are transferred from pytoplankton to fish and human, ultimately. Pyrethroid insecticides are utilized in place of organochlorine,organophosphorus and carbonate to control different forms of pests and raise yield. Pyrethroid intoxication causes cellular damage and increases freeradicals, which leads to lipid peroxidation and, ultimately, oxidative stress.To reduce damage to environment and biologicalsystems by pesticides should be played attention …
