month rolling average with no exceedances allowed 3 months Lead in Particle Matters Pb (in TSP) 34 of 86 Notes: *These values are based on a standard temperature of 25°C and a pressure of 1 atm. **To calculate ozone 8-hr value and to assign it to the appropriate day, the following rule is applied: The maximum daily eight-hour mean concentration shall be selected by examining eight-hour running averages, calculated from hourly data and updated each hour. Each eight - hour average so calculated shall be assigned to the day on which it ends. i.e. the first calculation period for any one day will be the period from 17:00 on the previous day to 01:00 on that day; the last calculation period for any one day will be the period from 16:00 to 24:00 on the day. ***Contributions from natural sources can be assessed but cannot be controlled. Therefore, where natural contributions to pollutants in ambient air can be determined with sufficient certainty, and where exceedances are due in whole or in part to these natural contributions, these may be subtracted when assessing compliance with air quality limit values. Demonstration is conducted through measurements, modeling of air masses back trajectories, remote sensing, and modeling. 35 of 86 Appendix 2 – Ambient Air Quality Standards for Hazardous Pollutants (µg.m-3)/ year (µg.m-3)/ 24 hours (µg.m-3)/ hour Pollutant 90 الاسيتالديهيد Acetaldehyde (C2H4O) 250 حمض الخليك Acetic Acid (CH3COOH) 5,900 الاسيتون Acetone (C3H6O) 60 حمض الأكريليك Acrylic Acid (C3H4O2) 43 الاكريلونيتريل Acrylonitrile (C3H3N) 180 الأمونيا Ammonia (NH3) 0.1 الزرنيخ Arsenic (As) 30 البنزين Benzene (C6H6) - بينزو(أ) بيرين Benzo[a] Pyrene (C20H12) 7 البروم Bromine (Br) 50 بروموفورم Bromoform (CHBr3) البوتادين1 Butadiene 1,3 (C4H6) 5.4 الكادميوم Cadmium (Cd) ثاني كبريتيد الكربون Carbon Disulfide (CS2) رابع كلوريد الكربون Carbon Tetrachloride (CCl4) 43 الكلور Chlorine (Cl) 100 كلوروفورم Chloroform (CHCl3) 500 الكومين Cumene (C9H12) 26,000 أثيل بنزين Ethylbenzene (C8H10) - الإيثيلين Ethylene (C2H4) ثاني بروميد الاثيلين Ethylene Dibromide (C2H4Br2) ثاني كلوريد الاثيلين Ethylene Dichloride (C2H4Cl2) 36 of 86 (µg.m-3)/ year (µg.m-3)/ 24 hours (µg.m-3)/ hour Pollutant 20 أكسيد الاثيلين Ethylene Oxide (C2H4O) 65 الفورمالديهايد Formaldehyde (CH2O) 1µg.m-3 for 30 days الفلوريدات Fluorides (F−) كلوريد الهيدروجين Hydrogen Chloride (HCl) سيانيد الهيدروجين Hydrogen Cyanide (HCN) فلوريد الهيدروجين Hydrogen Fluoride (HF) 10 يوديد الهيدروجين Hydrogen Iodide (HI) كبريتيد الهيدروجين Hydrogen Sulfide (H2S) 2 المنغنيز Manganese (Mn) 2,600 الميثانول Methanol (CH3OH) ميثيلين ثنائي الفينيل دي- إيزوسيانات Methylene Diphenyl Di-isocyanate (MDI) (C15H10N2O2) - النفثالين Naphthalene (C10H8) 0.1 النيكل Nickel (Ni) 100 الفينول Phenol (C6H6O) 4 الفوسجين Phosgene (COCl2) ال بوليمرية الميثيلين ثنائي الفينيل دي إيزوسيانات Polymeric Methylene Diphenyl di-Isocyanate (PMDI) (C15H10N2O2) - البروبيلين Propylene (C3H6) 480 أكسيد البروبيلين Propylene Oxide (C3H6O) 30 بيريدين Pyridine (C5H5N) - كبريتات Sulfate (SO42-) 215 الستايرين Styrene (C8H8) 37 of 86 (µg.m-3)/ year (µg.m-3)/ 24 hours (µg.m-3)/ hour Pollutant رابع كلور الإيثيلين Tetrachloroethylene (C2Cl4) 1,800 التولوين Toluene (C7H8) تولوين دي إيزوسيانات Toluene Di-isocyanate (TDI) (C9H6N2O2) - الفاناديوم Vanadium (V) 130 كلوريد الفينيل Vinyl Chloride (C2H3Cl) 2,300 الزيلين Xylene (C8H10)
