What contaminents release by fossil fuels in water?4 answersFossil fuels release various contaminants into water. The production of shale gas and shale oil involves hydraulic fracturing, which uses large amounts of water. This process can potentially contaminate drinking water resources with fluids from hydraulic fracturing or formation brines. Petroleum and petroleum products, including crude oil, can also pollute water through production, transportation, refining, and other activities. These pollutants can cause physiological disorders, diseases, and biological changes in the environment. Volatile fuel hydrocarbons and fuel additives, such as benzene, toluene, and methyl tert-butyl ether, can contaminate groundwater following release from underground storage tanks. Biodegradation limits the movement of these contaminants, but long-term monitoring is needed to understand their behavior. Fossil fuel extraction and refining processes, including natural gas fracking, can also pose risks to surface-water and groundwater quality.
How does the contaminant end up in water?5 answersContaminants end up in water through various human activities such as urbanization, industrialization, and agricultural activities. The overuse of pesticides and fertilizers, as well as sewage from residential and industrial areas, can find its way into aquatic environments, leading to water contamination. Dumping of industrial waste in low lying areas increases the chances of water contamination through percolation. Contaminants can reach water resources through underground and surface waters, as well as emissions from different industries. Wastewater discharged from industries may contain organic or inorganic matter, dyes, heavy metals, and pathogenic bacteria, which can contaminate water resources. Emerging contaminants can be introduced into water systems through wastewater treatment effluent, manufacturing, and agricultural use. The injection of toxic chemicals into the environment through industrialization and human activities has resulted in the presence of heavy metals in water bodies. Water can also be polluted by the disposal of untreated garbage, milling, and urbanization.
What are the most common contaminants found in mayonnaise?5 answersMayonnaise can be contaminated with various pathogens and contaminants. Salmonella, Clostridium perfringens, and Staphylococcus aureus are common pathogens found in homemade mayonnaise.
