Air Pollutant
• Contaminant that affects human life, plant life, animal life and property could be termed as an air pollutant.
– Introduction of a non-physical chemical– Change of the composition of the natural atmosphere (e.g.CO2 increase)
• Air pollutants are classified into two categories:
Primary pollutants: These pollutants are emitted from a source directly into the atmosphere. e.g. Sulfur dioxide and Hydrocarbons
Secondary pollutants: These are formed due to the chemical reaction among two or more pollutants.
e.g. Peroxyacetyl nitrate (PAN )

The problem of air pollution
Κλίμακες του προβλήματος• Παγκόσμια (παγκόσμια θέρμανση, μείωση
στρατοσφαιρικού όζοντος)• Περιφερειακή (όξινη βροχή)• Τοπική• Αστική• Κλίμακα δρόμου• Ρύπανση εσωτερικών χώρων
Τί είναι ατμοσφαιρική ρύπανση?Ατμοσφαιρική ρύπανση ορίζεται η μεταβολή της σύστασης ατμόσφαιρας, είτε από την είσοδο ενώσεων που δεν υπάρχουν στη φυσική της σύσταση, είτε από μεταβολή της συγκέντρωσης υπαρχόντων ενώσεων
Οι κυριότεροι ατμοσφαιρικοί ρύποι είναι:• Το Διοξείδιο του Θείου (SO2)• Το Μονοξείδιο του Άνθρακα (CO)• Τo Διοξείδιo του Αζώτου (NO2)• Το Όζον (O3)• Τα Αιωρούμενα Σωματίδια (κυρίως PM2.5, PM10)• Το Βενζόλιο (C6H6)• Ο Μόλυβδος (Pb)• Το διοξείδιο του Άνθρακα (CO2) σε συγκέντρωση
ανώτερη της φυσιολογικής
Πηγές ατμοσφαιρικών ρύπων:Ανθρωπογενείς πηγές• Βιομηχανική δραστηριότητα• Παραγωγή ενέργειας• Μεταφορές• Οικιακή θέρμανση• Χρήση καταναλωτικών προίόντων
Φυσικές πηγές• Βιογενείς εκπομπές• Ηφαίστεια
Επιπτώσεις ατμοσφαιρικής ρύπανσης• Ανθρώπινη υγεία• Οικοσύστημα - Βιόσφαιρα• Τεχνητό περιβάλλον

Major air pollutants
• Particulate matter (UFPs, PM1, PM2.5, PM10)
• Sulfur dioxide (SO2)
• Carbon monoxide (CO)
• Nitrogen dioxide (NO2)
• Ozon (O3)
• Benzene (C6H6)
• Lead (Pb)
• (CO2) at levels beyond normal

Source Classification
Transportation sources: Includes emissions from transportation sources during the combustion process
Stationary combustion sources: These sources produce only energy and the emission is a result of fuel combustion
Industrial sources: These sources emit pollutants during the manufacturing of products
Solid waste Disposal: Includes facilities that dispose off unwanted trash
Miscellaneous: sources that do no fit in any of the above categories like, coal mining etc.
Natural sources: Volcanos

Units for measurement of Air Pollution
There are two units of measurement. They are as follows: • µg/m3 and ppm (parts per million)
At 25°C and 1 atm
• At 00 C and at a pressure of 76 cm of Hg, volume of the air is 22.41 l/mol. • To obtain volume at any temperature, use gas law
P1V1/T1 = P2V2/T2
