How do chemicals affect the water?
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.
What harmful effects do chemicals have on water bodies?
Industrial and agricultural work involves the use of many different chemicals that can run-off into water and pollute it. Metals and solvents from industrial work can pollute rivers and lakes. These are poisonous to many forms of aquatic life and may slow their development, make them infertile or even result in death.
What are the causes of food pollution?
Causes of Food Pollution
- growing of food (e.g. crops, fruits, vegetables) in polluted soils, solid wastes (e.g. mine tailings) or areas with polluted groundwater;
- irrigation of grown food (e.g. vegetables, fruits, crops) with polluted water;
- growing of food (e.g. crops, fruits, vegetables) in areas with polluted air;
What are major causes of food contamination?
Infectious organisms — including bacteria, viruses and parasites — or their toxins are the most common causes of food poisoning. Infectious organisms or their toxins can contaminate food at any point of processing or production. Contamination can also occur at home if food is incorrectly handled or cooked.
What are the 3 ways that toxic chemicals can enter our waterways?
The different ways a person can come into contact with hazardous chemicals are called exposure pathways. There are three basic exposure pathways: inhalation, ingestion, and skin contact.
What are 4 major chemical pollutants?
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.
What are the 3 main negative effects of contaminating water with human wastewater?
Cholera and hepatitis, waterborne diseases, due to lack of sanitation caused by Cryptosporidium. Typhoid fever, stomach flu, and diarrhea.
What are the 10 causes of water pollution?
There are many causes of water pollution, some of them are:
- 1- Sewage or wastewater: The waste from households, factories, or agricultural land gets discharged into rivers or lakes.
- 2- Dumping:
- 3- Oil pollution:
- 4- Acid rain:
- 5- Industrial waste:
- 1- Diseases:
- 2- Ruination of the ecosystem:
- 3- Eutrophication:
What are the 5 effects of water pollution?
EFFECTS OF WATER POLLUTION
- Destruction of biodiversity. Water pollution depletes aquatic ecosystems and triggers unbridled proliferation of phytoplankton in lakes — eutrophication —.
- Contamination of the food chain.
- Lack of potable water.
- Infant mortality.
What are the 3 main causes of food contamination?
There are three ways that food can be contaminated:
- biological hazards (microorganisms) including bacteria, fungi, yeasts, mould and viruses.
- chemical hazards. including cleaning chemicals or foods with naturally occurring toxins, such as green potatoes.
- physical hazards.
What is the impact of pollution on food production?
There is a two way relationship between food production and air pollution: food production contributes significantly to air pollution; in turn, air pollution can impact food production. Agriculture is the single largest contributor of ammonia pollution as well as emitting other nitrogen compounds.
How do you stop pollution?
10 Best Ways to Reduce Air Pollution
- Using public transports.
- Turn off the lights when not in use.
- Recycle and Reuse.
- No to plastic bags.
- Reduction of forest fires and smoking.
- Use of fans instead of Air Conditioner.
- Use filters for chimneys.
- Avoid usage of crackers.
What are the 5 causes of food poisoning?
Top Foods Likely to Cause Food Poisoning
- Raw or undercooked meat and poultry.
- Raw or lightly cooked eggs.
- Unpasteurized milk, cheese, or other dairy products.
- Seafood and raw shellfish.
- Fruits and vegetables.
- Raw flour.
- Sprouts, such as alfalfa and mung bean.
What are two of the most common causes of contamination?
Raw foods of animal origin, that is, raw meat and poultry, raw eggs, unpasteurized milk, and raw shellfish are the most likely to be contaminated. Fruits and vegetables can also be contaminated with animal waste when manure is used to fertilize produce in the field, or unclean water is used for washing the produce.
What are the 4 types of contamination?
This guide will explore the different types of contamination and how they are likely to occur. The four main types of food contamination are chemical, microbial, physical, and allergen, and we will discuss these further.
