The criteria for including a chemical in this schedule is that it is not listed in either of the other two, and: It has been produced, stockpiled or used as a chemical weapon; It poses otherwise a risk to the object and purpose of the Convention because it possesses such lethal or incapacitating toxicity as well as other properties that might ...
The Lists themselves are divided into part A with toxic substances that can be used directly as chemical weapons and part B containing their precursors (chemicals with which those substances can be made). The Lists are subject to the following criteria, among others: [2] [3] Schedule 1 [4] contains substances most clearly related to a chemical ...
It may be used as a precursor in one of the chemical reactions at the final stage of formation of a chemical listed in Schedule 1 or Schedule 2, part b; It poses a significant risk to the object and purpose of this Convention by virtue of its importance in the production of a chemical listed in Schedule 1 or Schedule 2, part A;
Chemical alarm systems have been identified in a number of different taxa, including gastropods, [2] echinoderms, [3] amphibians [4] and fishes. One of the most well-studied chemical alarm signals is schreckstoff, the use of which is widespread in the superorder Ostariophysi (e.g., minnows, characins, catfishes, etc.). About 64% of all ...
A salmon which has died after spawning. Some species of fish exhibit mass simultaneous mortality as part of their natural life cycle. Fish kill due to spawning fatalities can occur when fish are exhausted from spawning activities such as courtship, nest building, and the release of eggs or milt (sperm). Fish are generally weaker after spawning ...
Diopatra claparedii are tubicolous, meaning they reside in a tube for much of their life cycle. [5] The tube is formed from sediment, rock, organic matter, and a mucus that the worm excretes, and can range from 30-60 cm in length, found in burrowed into sediments of littoral environments of South Asian coastal waters, with varying lengths visible above ground.
Adamantium is not depicted as a naturally occurring metal but as having been inadvertently invented by fictional American metallurgist Dr. Myron MacLain in trying to recreate his prior discovery, a unique alloy of steel and vibranium. Despite its potential uses in armament and armature, adamantium is rarely used due to high cost and inability ...
Pre-spawn mortality is a phenomenon where adult coho salmon, Oncorhynchus kisutch, die before spawning when returning to freshwater streams to spawn. [1] [2] It is also known as Urban Runoff Mortality Syndrome in more recent studies. [3] [4] This occurrence has been observed in much of the Puget Sound region of the Pacific Northwest. [5]
