When oil or petroleum distillates are combusted, usually the combustion is not complete and the chemical reaction tree leaves by-products which are not water or carbon dioxide. However despite the large amounts of pollutants there is uncertainty about the amount and concentration of certain pollutants. 8 In the refinement stages of petroleum also contributes to large amounts of pollution in urban areas. This increase of pollution has adverse effects on human health due to the toxicity of oil. A study investigating the effects of oil refineries in taiwan. The study found an increased occurrence of pre-mature births in mothers that lived in close proximity to oil refineries than mothers who lived away from oil refineries. There were also differences observed in sex ratios and the birth weight of the children. 4 Also, fine particulates of soot blacken humans' and other animals' lungs and cause heart problems or death. Soot is cancer causing ( carcinogenic ) 1 Acid rain edit main article: Acid rain Trees killed by acid rain, an unwanted side effect of burning petroleum The combustion process of petroleum, coal, and wood is responsible for increased occurrence of acid rain.
The toxicity of petroleum related products threaten human health. Many compounds found in oil are highly toxic and can cause cancer ( carcinogenic ) as well as other diseases. 1 Studies in taiwan link proximity to twist oil refineries to premature births. 4 Crude oil and petroleum distillates cause birth defects. 5 Benzene is present in both crude oil and gasoline and is known to cause leukaemia in humans. 6 The compound is also known to lower the white blood cell count in humans, which would leave people exposed to it more susceptible to infections. 6 "Studies have linked benzene exposure in the mere parts per billion (ppb) range to terminal leukemia, hodgkin's lymphoma, and other blood and immune system diseases within 5-15 years of exposure." 7 Exhaust edit main article: Air pollution Petroleum diesel exhaust from a truck Emissions. In the extraction phase there are emissions of not only carbon dioxide but various other pollutants like nitrous oxides and aerosols. 8 Certain by - products include carbon monoxide and methanol.
2, generally oils that have longer carbon chains and with more benzene rings have higher levels of toxicity. Benzene is the petroleum related product with the highest level of toxicity. Other substances other than benzene which are highly toxic are toluene, methylbenzene and xylenes (betx). 2 Substances with the lowest toxicity are crude oil and motor oil. 2 Despite varying levels of toxicity amongst different variants of oil, all petroleum -derived products have adverse impacts on human health and the ecosystem. Examples of adverse effects are oil emulsions in digestive systems in certain mammals might result in decreased ability to digest nutrients that might lead to death of certain mammals. Further symptoms include capillary ruptures and hemorrhages. Ecosystem food chains can be affected due to a decrease in algae productivity therefore threatening certain species. 2 Oil is "acutely lethal" to fish - that is, it kills fish quickly, at a concentration of 4000 parts per million ( ppm ) 3 (0.4).

1, there are many methods that can be used to measure the toxicity of crude oil and other petroleum related products. Certain studies analyzing levels of toxicity can use the target lipid model or colorimetric analysis using colored-dyes in order to assess toxicity and biodegradability. 2, different oils and petroleum related products have different levels of toxicity. Levels of toxicity are influenced by many factors such as weathering, solubility, as well as chemical properties such as persistence. Increased weathering tends to decrease levels of toxicity as more soluble and lower molecular weight substances are removed. 1, highly soluble substances tend to have higher levels of toxicity than substances that are not very soluble in water.
