A yellow, crystalline compound used mainly as an explosive. Because of the toxicity of TNT, discharge of pink water to the environment has been prohibited in the US and many other countries for decades, but ground contamination may exist in very old plants. [39], Photolysis is a major process that impacts the transformation of energetic compounds. [38] This means that TNT has a one- to tenfold tendency to adhere to soil particulates than not when introduced into the soil. Having said that TNT uses WW which we believe must stand for worldwide. They can place it near a power source and cause it to detonate. [39], The ligninolytic physiological phase and manganese peroxidase system of fungi can cause a very limited amount of mineralization of TNT in a liquid culture; though not in soil. For this reason, a group of people known as Radford’s P2 Team invented a new way of making TNT. [32], Compared to other explosives, TNT has a higher association constant with soil, meaning it adheres more with soil than with water. - Definition & Examples, What is an Elastomer? However, when salinity was altered, TNT dissolved at the same speed (Figure 2). Anyone can join the Tierion Network and start earning TNT. Building Implosion Image Gallery.
