…..over a two-week period.This period should be specified if it has climate specific parameters!How representative is this period to whole year?Page 2 -Introduction …..nitrogen dioxide (NO2), sulfur dioxide (SO2), carbon monoxide (CO), ozone (O3),….. Correct the lower index for chemical compounds. Page 3 -IntroductionCarbon monoxide (CO 2 ) is a toxic gas that can cause headaches, dizziness, and nausea.It is produced by the incomplete combustion of fossil fuels, such as in vehicles and generators.Ozone is a reactive gas that can cause respiratory problems and aggravate asthma.It is formed when nitrogen oxides and volatile organic compounds (VOCs) react in the presence of sunlight. Correct the carbon monoxide (CO) / carbon dioxide (CO 2 ) -correct text for each chemical compounds!!!! Correct text for ozone -the information is doubled -see text above.Lead (Pb) is a heavy metal that can cause neurological and developmental problems in children.It comes from sources such as leaded gasoline and industrial emissions.Divide the text into 2 paragraphs.Is it true about gasoline?In Europe the lead is not used in gasoline for decades.Volatile organic compounds (VOCs) are organic chemicals that can have both short-and long-term health effects, such as eye, nose, and throat irritation, headaches, and damage to the liver, kidneys, and central nervous system.They come from sources such as paints, solvents, and cleaning products (World Health Organization.(2019).Also some building materials used in indoor environments may be source of VOC as adhesive from laminated wood, etc.. Page 5 -2.1 Study areaSpecify the area of Lead City University -m 2 or similar information.Give percentage of build and open areas.Give number of people (students, staff, etc.) attended the University.
