[4] [5] Biological hazards, also known as biohazards, are organic substances that pose a threat to the health of living organisms, primarily humans. This can include medical waste, samples of a microorganism, virus, or toxin (from a biological source) that can impact human health. Biological hazards can also include substances harmful to animals.
This ultimately affects all living organisms that comprise an ecosystem. Ecotoxicology has been defined as a branch of toxicology that focuses on the study of toxic effects, caused by natural or synthetic pollutants. These pollutants affect animals (including humans), vegetation, and microbes, in an intrinsic way. [1]
A biological hazard, or biohazard, is a biological substance that poses a threat (or is a hazard) to the health of living organisms, primarily humans. This could include a sample of a microorganism, virus or toxin that can adversely affect human health. A biohazard could also be a substance harmful to other living beings. [a]
Organisms include those harmful to human health, or to animal health. [1] The Plant Protection and Quarantine programs (PPQ) of the Animal and Plant Health Inspection Service (APHIS) are listed in 7 CFR Part 331. The Department of Health and Human Services (HHS) lists are located at 42 CFR Part 73.3 [2] and 42 CFR Part 73.4. [3]
[32] [33] These pollutants are responsible for the burning of fuel, which can release harmful particles into the air that humans and other living organisms can inhale or ingest. [ 34 ] Air pollution is associated with adverse health effects like respiratory and cardiovascular diseases, cancer , related illnesses, and even death. [ 35 ]
A microbiologist working on the reconstructed virus of the 1918 Spanish Flu, using a fume hood for biocontainment. [1]Biosecurity refers to measures aimed at preventing the introduction or spread of harmful organisms (e.g. viruses, bacteria, plants, animals etc.) intentionally or unintentionally outside their native range or within new environments.
A lower ocean pH has a range of potentially harmful effects for marine organisms. Scientists have observed for example reduced calcification, lowered immune responses, and reduced energy for basic functions such as reproduction. [69] Ocean acidification can impact marine ecosystems that provide food and livelihoods for many people.
The Amanita muscaria mushroom, an iconic toxic mushroom.. A toxin is a naturally occurring poison [1] produced by metabolic activities of living cells or organisms. [2] They occur especially as proteins, often conjugated. [3]
