[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.
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]
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]
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]
More than 1,200 different kinds of potentially weaponizable bio-agents have been described and studied to date. Some biological agents have the ability to adversely affect human health in a variety of ways, ranging from relatively mild allergic reactions to serious medical conditions, including serious injury, as well as serious or permanent ...
Mycotoxins can be harmful because they can cause disease and death in humans and animals. [35] They are found in many pharmaceuticals like antibiotics and growth developments. [ 35 ] Mycotoxins can also play a role in chemical warfare agents (CWA), which are chemicals that contain toxins that are used to cause death, harm, or injuries to ...
A food contaminant is a harmful chemical or microorganism present in food, which can cause illness to the consumer. Contaminated food . The impact of chemical contaminants on consumer health and well-being is often apparent only after many years of processing and prolonged exposure at low levels (e.g., cancer). Unlike food-borne pathogens ...
Environmental toxicology is a multidisciplinary field of science concerned with the study of the harmful effects of various chemical, biological and physical agents on living organisms. [1] [2] Ecotoxicology is a subdiscipline of environmental toxicology concerned with studying the harmful effects of toxicants at the population and ecosystem ...
