A Review on Adverse Effects of Herbicides and Pesticides on Environment
Abstract: Pesticides can contaminate soil, water, turf, and other vegetation. Insecticides are generally the most acutely toxic class of pesticides, but herbicides can also pose risks to non-target organisms. The environment includes all of the living and non-living things that surround us, including the air, water, plants, soil and wildlife. Pesticides can be helpful in dealing with pests in our environment such as controlling invasive plant species that threaten native habitats. …

Analysis of the Dangerous Impacts of Food Preservatives
Abstract: Every living thing requires nourishment to survive. Nutrients found in food include vitamins, minerals, fats, proteins, and carbohydrates. In order to produce energy, promote development, and sustain life, an organism must consume and digest the nutrients included in food. Some preservatives are used to extend the shelf life and maintain the quality of food, but they may have negative side effects; therefore, whenever possible, preservative-free foods should be used. In …

The Improvement of Polyvinyl Chloride Synthesis Using Different Approaches
Abstract: Polyvinyl chloride (PVC) is produced by the polymerization of the vinyl chloride monomer either by direct chlorination of olefins or by addition of hydrogen chloride to acetylene. The polymerization conditions are: heat, peroxides or oxidizing agents with basic structure as -CH2CHCl.CHCl-CH2.CHCl-. Polyvinyl chloride is a thermoplastic and its plasticity can be increased by incorporating ‘plasticizers’ of relatively low molecular weight organic materials during molding or extrusion. PVC has high hardness …

Techno-Economic Analysis of Packed Bed Type Thermal Batteries for Surplus Renewable Energy Storage
Abstract: Low carbon electricity from renewables will form the bed rock of the energy transition necessary for climate change mitigation. However, variable renewable generators suffer from intermittency and variability – there can be large surplus power available at times which cannot be dispatched to the grid. At many times, the practice is to curtail surplus renewable output, which is wasteful and not economic. There are also phases when generation is not …
