NO 2 reacts with hydrocarbons to form ozone or with water to form nitrate (NO 3), a significant source of acid rain. odour increased sensitivity of asthmatics and those suffering from bronchitis NO 2 is a lung irritant which can produce pulmonary edema at high concentrations increased susceptibility to respiratory infections in young children and the elderly NO 2 reacts with water to form nitrate (NO 3), a source of acid rain Acid rain accounts for an annual loss of $197 billion in commercial forest wood products and a further $1.3 billion due to recreation and wildlife habitat destruction NO 2 contributes to the corrosion of metals and degradation of textiles, rubber and polyurethane NO 2 is associated with suppressed vegetation growth NO 2 contributes to ground-level ozone formation NO 2 contributes to stratospheric ozone depletion Carbon Monoxide (CO) CO is a colourless, odour less and tasteless gas produced through the incomplete combustion of organic materials. Personal vehicles are one of the main sources of CO, accounting for 54% of total CO emissions. Cars operating at colder temperatures (during winter or engine warm-up) produce significant quantities of this poisonous gas CO reduces the ability of the blood to carry oxygen, and smokers, persons with heart disease, and those with anemia are especially sensitive greater susceptibility to respiratory infections in children and elderly CO released into the atmosphere depletes the atmosphere's supply of OH (hydroxyl radical) which is the main natural cleansing agent of the atmosphere. As a result, CO emissions contribute to increases in methane, partially halogenated CFCs and the formation of ozone under certain NOx conditions.

Carbon Dioxide (CO 2) CO 2 is a gas that comes from the decay of materials, respiration of plants and animal life and the natural and human-induced combustion of materials and fuels. Since the industrial revolution, the natural cycle of release and absorption of CO 2 in the atmosphere has become unbalanced due to an increase in human-produced CO 2 which contributes to global warming. Indirect impact includes: increased deaths related to heat waves, dramatic weather events, increased transmission of vector-borne and infectious diseases. CO 2 is the most significant greenhouse gas contributing to global warming Hydrocarbons (including VOC) A numerous and chemically diverse group of compounds, non-methane hydrocarbons and volatile organic compounds (VOC) are important in the formation of ozone.

VOC have at least one carbon atom and evaporate easily. many individual VOC (e. g., benzene) are known to have or are suspected of having human health effects ranging from carcinogenicity to neurotoxicity some hydrocarbons from diesel emissions are carcinogenic VOC contribute to the formation of ground-level ozone Ozone (O 3) Ozone is formed when NOx and VOC combine in the presence of sunlight. decrease in lung function eye irritation decreased immune function possible long term role in the development of chronic lung disease reduced agricultural productivity in crops including soybeans, tomatoes, potatoes and corn reduced growth rate in trees including red spruce, yellow pine and sugar maple ground-level ozone is a global warming agent Suspended Particulates Suspended particulates are small particles of solid and liquid matter found in most fuel emissions but are found in significantly higher quantities in diesel emissions. small particles can penetrate lungs and cause respiratory infections toxic particles can be taken into the blood stream effects vary with the type of particulates decreased visibility aesthetic damage to buildings.
