Oil toxicity: Oil consists of many different toxic compounds. These toxic compounds can cause severe health problems like heart damage, stunted growth, immune system effects, and even death . Our understanding of oil toxicity has expanded by studying the effects of the 2010 Deepwater Horizon oil spill.
What are some effects of oil spills?
Oil spills frequently kill marine mammals such as whales, dolphins, seals, and sea otters. 10 Oil can clog blowholes of whales and dolphins, making it impossible for them to breathe properly and disrupting their ability to communicate. Oil coats fur of otters and seals, leaving them vulnerable to hypothermia.
What are the causes and negative effects of oil pollution?
Oil pollutants threaten birds, fish and marine mammals that absorb, eat or inhale them . ... Ingesting or inhaling oil can result in lung, liver and kidney damage that ends in death, as well as a weakened immune system that compromises an animal’s ability to find food and protect itself against predators.
What are the causes of oil pollution?
Oil spills that happen in rivers, bays and the ocean most often are caused by accidents involving tankers, barges, pipelines, refineries, drilling rigs and storage facilities, but also occur from recreational boats and in marinas. Spills can be caused by: people making mistakes or being careless.
How does oil pollution affect the environment?
When oils rigs or machinery malfunction or break, thousands of tons of oil can seep into the environment . Oil spill effects on environments and habitats can be catastrophic: they can kill plants and animals, disturb salinity/pH levels, pollute air/water and more.
How do oil spills affect humans and the environment?
Studies of biomarkers have uncovered irreparable harm to humans exposed to oil and gas from spills. These effects can be grouped into respiratory damage , liver damage, decreased immunity, increased cancer risk, reproductive damage and higher levels of some toxics (hydrocarbons and heavy metals).
Does oil pollute the air?
The U.S. oil and gas industry pollutes the air with methane and volatile organic compounds (VOCs) . ... In association with methane emissions, the oil and gas industry pollutes the air with different gases that threaten human health: Volatile Organic Compounds (VOCs) including carcinogens such as benzene.
What are the long-term effects of oil spills?
Large-scale persistent ecological effects included impacts to deep ocean corals, failed recruitment of oysters over multiple years , damage to coastal wetlands, and reduced dolphin, sea turtle, and seabird populations.
What is the effect after oil flows out of the ship?
Oil spills present the potential for enormous harm to deep ocean and coastal fishing and fisheries. The immediate effects of toxic and smothering oil waste may be mass mortality and contamination of fish and other food species , but long-term ecological effects may be worse.
How does oil spills affect the economy?
And while long-term damage estimates vary, a new study published in the Canadian Journal of Fisheries and Aquatic Sciences determined that over seven years, the oil spill could have a $8.7 billion impact on the economy of the Gulf of Mexico including losses in revenue, profit, wages , and close to 22,000 jobs.
What are two negative impacts of oil spills?
Spilled oil can harm the environment in several ways, including the physical damages that directly impact wildlife and their habitats (such as coating birds or mammals with a layer of oil), and the toxicity of the oil itself , which can poison exposed organisms.
How does oil affect climate change?
The Problem With Oil: Global Warming
Burning oil releases carbon dioxide into the atmosphere , contributing to the warming of our planet. ... In order to avoid the worst impacts of climate change, scientists say the world cannot afford to burn more than one-third of known oil reserves.
What type of pollution is an oil spill?
An oil spill is the release of a liquid petroleum hydrocarbon into the environment , especially the marine ecosystem, due to human activity, and is a form of pollution. The term is usually given to marine oil spills, where oil is released into the ocean or coastal waters, but spills may also occur on land.
Which animal is killed for oil?
At least four species of marine mammals have been killed by the oil spill, including bottlenose dolphins, spinner dolphins, melon-headed whales and sperm whales .

How do oil spills affect humans and animals?
Oil destroys the insulating ability of fur-bearing mammals , such as sea otters, and the water repellency of a bird’s feathers, thus exposing these creatures to the harsh elements. Without the ability to repel water and insulate from the cold water, birds and mammals will die from hypothermia.
