In arsenic contaminated areas of the Ganga–Meghna–Brahmaputra (GMB) plain (area 569 749 sq. km; population over 500 million) where traditionally cow dung cake is used as a fuel in unventilated ovens for cooking purposes‚ people are simply exposed to 1859.2 ng arsenic per day through direct inhalation‚ of which 464.8 ng could be absorbed in respiratory tract. Introduction Arsenic has been considered as a human carcinogen and causes multiple adverse health effects.1 Groundwater arsenic contamination

Fossil Fuels: Oil Introduction History We are a country that runs on oil. From the gasoline in our cars to the plastic in our computers to the detergents that we put in our dishwashers‚ we rely on oil for our modern way of life. It cannot be understated just how strong of a role it plays in our economy and politics. It is used in tractors that plow and harvest food. It is used to power manufacturing plants and as feedstock in commercial goods. It powers all the trains and trucks that bring goods

Hydrogen Fuel As An Alternative Energy Source To Replace Fossil Fuels Since the beginning of industry humans have been in search of fuel to power machines and generate energy. Fossil fuels‚ such as crude oil and coal‚ discovered beneath the Earth’s surface were found to be an excellent source of fuel. These fossil fuels are burnt in order to generate the energy required to complete various tasks. Many nations count on coal‚ oil and natural gas to supply most of their energy needs‚ but reliance

Fuel Hedging A Strategy for Air Carriers to Combat Fuel Hike Index Jet Fuel – The Nemesis of Airlines In the year 2008‚ the growth of global aviation industry received a major bolt from the fear of global economic slowdown and the rise in crude oil prices. Though the global economic uncertainties impacted the business of airlines‚ but the steep surge in crude prices has changed the financial equations of the airline across the world‚ with India being no exception. In fact over the previous

Fossil fuels comprise 80 percent of current global primary energy demand‚ and the energy system is the source of approximately two thirds of global carbon dioxide emissions as of 2015 (Foster and Elzinga). For decades‚ people have argued about whether fossil fuels are helpful to the planet and sustainability. Although‚ there is no right or wrong answer because renewable and non-renewable resources have disadvantages and advantages. There are very many different variables to be considered in this

Using ethanol as an alternate fuel‚ or fuel extender includes a heterogenous agglomeration of advantages and disadvantages. On cars: ethanol is preferable to lead as an octane booster. A 10% addition of ethanol to petrol is more effective than lead at boosting octane rating (+2.5) and making car run smoother. It’s cheaper than lead‚ and ethanol-blended fuels leave no gummy deposits‚ thus keeps engine clean. Although a minimal 10% ethanol blend should be compatible with internal combustion engines

INTRODUCTION According to Wikipedia‚ fuel is any material that stores energy that can later be extracted to perform mechanical work in a controlled manner. A fuel contains energy‚ mostly heat‚ which can be released and then manipulated. Most fuels used by humans undergo combustion‚ a redox reaction in which a combustible substance releases energy after it ignites and reacts with the oxygen in the air. Other processes used to convert fuel into energy include various other exothermic chemical

Fossil Fuel Dependency and Americans One of the major underlying problems Americans are faced with today is what to do about the dependency on fossil fuels. Petroleum dependence is a big problem for the United States because the supply will be depleted soon if consumers continue to use it at the rate they use it now. If consumers want to keep their engines running and lights on‚ there must be a drastic change in the sources of energy supply. An issue the whole world faces today is the reliance
