Chemical compounds are any substance composed of molecules. Molecules consist of two or more atoms of chemical elements. Chemical compounds are classified to organic and inorganic compounds. Organic compounds are a large group of chemical compounds from which all living organisms are made...
Carbohydrates, proteins, lipids, nucleoprotein, enzymes, hormones, vitamines are the main organic compounds of protoplasm.
As Volatile Organic Compounds exist as a gas at room temperature the main exposure route is through normal respiration. Exposure to harmful VOCs can happen at home, outdoors, or in the workplace. Air Pollution Air pollution is now something we are all aware of and is often included alongside...

One of the primary sources of this pollution is furnishings and building materials, which can release hundreds of VOCs into the air. Breathing these pollutants is linked to a variety of health problems, including allergies, asthma, cardiovascular disease, reproductive disorders and some forms of canc...
looking-up information in textbooks and via other sources and media.Most biological chemicals, i.e. those generated by plant or animal life, are organic because they include carbon-hydrogen bonds. However that is a very general observation and there are too many common exceptions to use it as...
In the maritime industry, VOCs are mainly generated inoil and chemical tankers, which are involved in loading, transporting and unloading organic chemical substances through ports. Volatile Organic Compounds are generated when cargo splashes in the piping system of the ships from the source to the ...
Methane and nitrous oxide are emitted into the atmosphere in much smaller quantities than CO2, but they still have a significant effect on climate. 甲烷和一氧化二氮被排放到大气中的数量比二氧化碳少得多,但它们仍然对气候有重大影响。 When comparing the different impacts of these gases, we usually ...
