Ricin is very toxic if inhaled, injected, or ingested. It can also be toxic if dust contacts the eyes or if it is absorbed through damaged skin. It acts as a toxin by inhibiting protein synthesis. [27] [28] Ricin is resistant, but not impervious, to digestion by peptidases. By ingestion, the pathology of ricin is largely restricted to the ...
Rosin (/ ˈ r ɒ z ɪ n /), also known as colophony or Greek pitch (Latin: pix graeca), is a resinous material obtained from pine trees and other plants, mostly conifers.The primary components of rosin are diterpenoids, i.e., C 20 carboxylic acids.
A resin is a solid or highly viscous liquid that can be converted into a polymer. [1] Resins may be biological or synthetic in origin, but are typically harvested from plants. Resins are mixtures of organic compounds, and predominantly terpenes. Well known resins include amber, hashish, frankincense, myrrh and the animal-derived resin, shellac.
Humans are exposed to toxic chemicals and microplastics at all stages in the plastics life cycle. Microplastics effects on human health are of growing concern and an area of research. The tiny particles known as microplastics (MPs), have been found in various environmental and biological matrices, including air, water, food, and human tissues.
10 Common Foods That Can Be Poisonous. Fruits, vegetables, seeds and beans are all essential parts of a well-balanced and healthy diet, but if these health gems are not consumed properly, they ...
Dragon's blood, powdered pigment or apothecary's grade and roughly crushed incense, extracted from Calamus draco. Dragon's blood is a bright red resin which is obtained from different species of a number of distinct plant genera: Calamus spp. (previously Daemonorops) also including Calamus rotang, Croton, Dracaena and Pterocarpus.
A study by Soviet researchers in the 1980s suggested that melamine cyanurate, commonly used as a fire retardant, [27] could be more toxic than either melamine or cyanuric acid alone. [28] For rats and mice, the reported LD 50 for melamine cyanurate was 4.1 g/kg (given inside the stomach) and 3.5 g/kg (via inhalation), compared to 6.0 and 4.3 g ...
Research on the health and safety hazards of 3D printing is new and in development due to the recent proliferation of 3D printing devices. In 2017, the European Agency for Safety and Health at Work has published a discussion paper on the processes and materials involved in 3D printing, potential implications of this technology for occupational safety and health and avenues for controlling ...
