Synthetic Clmpounds and Pollutants1. Small suspended matter that can be drawn to the lungsThese are particulate matter (PM) — tiny particles or droplets in the air that can penetrate deep into the respiratory system, causing health problems like asthma, bronchitis, or even lung cancer.2. Pollutants considered as carcinogenic, mutagenic, and teratogenicThese are toxic substances that can cause cancer (carcinogenic), genetic mutations (mutagenic), or birth defects (teratogenic). Examples include certain synthetic chemicals like benzene, phenol, and toluene.3. Any form of precipitation that is unusually low in pHThis describes acid rain, which occurs when sulfur dioxide (SO₂) and nitrogen oxides (NOx) react with water vapor in the atmosphere, creating rain with a pH less than 5.6. Acid rain damages ecosystems, buildings, and aquatic life.4. Produced from the incomplete combustion of fossil fuelThis refers to carbon monoxide (CO), a toxic gas produced when fossil fuels like gasoline, coal, or wood burn inefficiently without enough oxygen. CO is dangerous because it binds to hemoglobin, reducing oxygen transport in the blood.5. Synthetic compounds such as benzene, phenol, and tolueneThese are volatile organic compounds (VOCs), common in industrial emissions and solvents. They contribute to air pollution and can harm human health and the environment.6. A metallic poisonThis likely refers to lead (Pb), a heavy metal pollutant historically found in gasoline and paint. Lead exposure affects the nervous system, especially in children.7. Greenhouse gasGases like carbon dioxide (CO₂) and methane (CH₄) trap heat in the atmosphere, contributing to global warming and climate change.8. Pollutants that are released in a harmful formThis generally means hazardous air pollutants (HAPs) — substances released into the air that cause serious health effects or environmental damage.9. Highly reactive gas that is formed when nitrogen is heatedThis is nitrogen oxides (NOx), formed during high-temperature combustion processes such as car engines or power plants. NOx contributes to smog and acid rain.10. Occurs when polluted air stagnates over an areaThis is called a temperature inversion, where a layer of warm air traps pollutants close to the ground, leading to poor air quality and smog buildup.
