Toxicity is the degree to which a chemical substance or a particular mixture of substances can damage an organism. [1] Toxicity can refer to the effect on a whole organism, such as an animal, bacterium, or plant, as well as the effect on a substructure of the organism, such as a cell (cytotoxicity) or an organ such as the liver (hepatotoxicity).
Climate change affects human health at all ages, from infancy through adolescence, adulthood and old age. [3] Factors such as age, gender and socioeconomic status influence to what extent these effects become wide-spread risks to human health. [9]: 1867 Some groups are more vulnerable than others to the health effects of climate change. These ...
Examples of biological hazards include bacteria, viruses, fungi, other microorganisms and their associated toxins. They may cause a myriad of diseases, from flu to more serious and potentially fatal diseases. [4] Psychological hazards are aspects of work and work environments that can cause psychological harm or mental ill-health.
Because the available scientific studies provide limited information regarding toxicity and health effects to humans, the increase in use of these chemicals and their effects on human health are ...
By contrast, a toxin is a poison produced naturally by an organism (e.g. plant, animal, insect). [2] The 2011 book A Textbook of Modern Toxicology states, "A toxin is a toxicant that is produced by a living organism and is not used as a synonym for toxicant—all toxins are toxicants, but not all toxicants are toxins.
If plants are battling problems with diseases relating to exposure to chemicals, other organisms will either die because of starvation or obtain the disease by eating the plants or animals already infected. So ecotoxicology is an ongoing battle that stems from many sources and can affect everything and everyone in an ecosystem.
The chemicals within these PPCP products could either affect the feminization or masculinization of different fishes, therefore affecting their reproductive rates. [17] In addition to being found only in waterways, the ingredients of some PPCPs can also be found in the soil.
Humans are exposed to toxic chemicals and microplastics at all stages in the plastics life cycle. The effects of microplastics on human health are a growing concern and an actively increasing area of research. Tiny particles known as microplastics (MPs), have been found in various environmental and biological matrices, including air, water ...
