The emission of certain substances to the atmosphere produces a greenhouse effect
contributing to the global warming. … A variety of other gases contributes to the greenhouse effect, including solvents, chlorofluorocarbons and other volatile organic compounds (VOCs), or nitrogen and sulphur oxides.
How do chemicals affect the atmosphere?
The release into the air of chemicals and particles can cause
direct damage to the troposphere
(air pollution); alter the composition and function of atmospheric layers (greenhouse effect) or other indirect damages (ozone layer depletion).
What are the chemicals involved that pollute the environment?
There are 10 substances that cause the most concern:
Carbon Monoxide, Sulfur Dioxide, Carbon Dioxide, Volatile Organic Compounds (VOCs)
, Particulates, Nitrogen Oxides, Ozone, Chlorofluorocarbons, Unburned Hydrocarbons and Lead and Heavy metals.
How do chemicals affect marine life?
As it rains, those chemicals are washed into rivers, which feeds the waterfalls and then goes into the ocean. When a toxic waste harms one organism, it can
end up destroying an entire food chain of aquatic life
. Improperly disposed chemicals pollute marine life and kills sea mammals, corals, and fish.
How does pollution affect the environment and animals?
Air pollution negatively affects wildlife by
changing plant communities
. Stunted plant growth from atmospheric ozone affects the quality of habitat and food sources. Birds are threatened directly by coal power production exhaust, which damages their respiratory systems. Air pollution also indirectly threatens birds.
How do agricultural chemicals affect the environment?
Impact on environment
Pesticides
can contaminate soil, water, turf, and other vegetation
. In addition to killing insects or weeds, pesticides can be toxic to a host of other organisms including birds, fish, beneficial insects, and non-target plants.
Why are chemicals important?

; that we can buy goods and clothing; and that we have continual access to telecommunication, media and music wherever we are.
Why are humans concerned about chemicals in the environment?
Chemicals can be of concern
because of their pervasiveness, potential to accumulate, possibilities of interaction, and often long-term unknown effects on people and the environment
(e.g., cancer, mercury in fish).
How does releasing chemicals into the atmosphere affect climate change?
Heat-trapping gases like
carbon dioxide (CO2) absorb this infrared radiation and prevent it from dissipating into space, giving rise to what we know as the greenhouse effect. The accumulation of CO2 and other greenhouse gases in the atmosphere is the dominating driver of recent climate change.
Is releasing chemical into the environment?
Each and every second 310 Kg of toxic chemicals are released into our air, land, and water by
industrial facilities
around the world. This amounts to approximately 10 million tons (over 21 billion pounds) of toxic chemicals released into our environment by industries each year.

- Global warming. …
- Overpopulation. …
- Waste disposal. …
- Ocean acidification. …
- Loss of biodiversity. …
- Deforestation. …
- Ozone layer depletion.
What is a chemical pollutant?
A chemical substance that enters the environment through industrial, agricultural or other human activities, which poses an immediate or potential hazard to plant, animal or human life; the major chemical pollutants are heavy metals (e.g.,

What are the harmful effects of chemical pesticides?
Examples of acute health effects include stinging eyes, rashes, blisters, blindness,
nausea, dizziness, diarrhea and death
. Examples of known chronic effects are cancers, birth defects, reproductive harm, immunotoxicity, neurological and developmental toxicity, and disruption of the endocrine system.
How do chemicals affect agriculture?
EFFECTS OF AGRICULTURAL CHEMICALS IN SOIL
The main difference from cultivation is that
the effects of chemicals lasts longer
. Whereas ploughing or rotation may only change the balance of the soil fauna or flora for a matter of weeks or at most months, persistent chemicals can alter them for months or years”.
What is chemical pollution in the ocean?
