Types of Groundwater Pollutants Biological pollutants include bacteria, viruses, and parasites that are responsible for waterborne diseases, such as typhoid fever, cholera, dysentery, polio, hepatitis, and schistosomiasis.

What is biological contamination in food?

Briefly, biological contamination is when food is contaminated with infectious bacteria (such as Salmonella spp. and L. monocytogenes) or toxin-producing organisms (such as Clostridium botulinum) and viruses (such as norovirus), which are a common cause of food poisoning and food spoilage.

What is the solution of pollution?

The most basic solution for air pollution is to move away from fossil fuels, replacing them with alternative energies like solar, wind and geothermal. Producing clean energy is crucial. But equally important is to reduce our consumption of energy by adopting responsible habits and using more efficient devices.

How can we save our environment from pollution essay?

For this, there must be control of landslides, floods, and soil erosion. Furthermore, there should also be afforestation and tree plantation to conserve the soil. Also, terrace farming and using natural fertilizers are some more ways. Waste management is a powerful way of protecting the environment.

Is human hair a biological contamination?

Hair is a source of microbiological contamination as the human scalp often contains Staphylococcus Aureus, a food poisoning organism. Therefore any hair in food can be a root cause of cross contamination and can indeed make us ill.

  1. Wash hands and surfaces often.
  2. Wash hands with soap and hot water before and after handling food, and after using the bathroom, changing diapers; or handling pets.
  3. Use hot, soapy water and paper towels or clean cloths to wipe up kitchen surfaces or spills.

Carefully wash cooking equipment, utensils, and food surfaces both before and after food preparation using soap and water hot enough to tolerate or in a dishwasher that uses water at a temperature that kills microorganisms. Separate cooked meats from raw foods to prevent cross-contamination.

What are 5 biological food hazards?

Examples of biological hazards are: disease-causing bacteria, viruses, parasites, molds, yeasts, and naturally occurring toxins.

Which is an example of biological contaminant in water *?

Biological contaminants are organisms in water. They are also referred to as microbes or microbiological contaminants. Examples of biological or microbial contaminants include bacteria, viruses, protozoa, and parasites.

What are biological hazards?

Biological health hazards include bacteria, viruses, parasites and moulds or fungi. They can pose a threat to human health when they are inhaled, eaten or come in contact with skin. They can cause illness such as food poisoning, tetanus, respiratory infections or parasite infection.

Does rain have acid?

Normal rain has a pH of about 5.6; it is slightly acidic because carbon dioxide (CO2) dissolves into it forming weak carbonic acid. Acid rain usually has a pH between 4.2 and 4.4.
