Low-VOC paint types include latex (water-based), acrylic, and milk paint, with most relatively easy to recycle. [1] [2] The labels of paint cans can be checked for the following information: To be considered low-VOC, the paint should contain <50 g/L of VOC. [citation needed] To be considered zero-VOC, the paint should contain <5 g/L of VOC.
Cultural heritage collections contain many materials known to be hazardous to the environment and to human health. Some hazardous substances may be an integral part of the object (such as a toxic paint pigment or a naturally radioactive mineral sample), applied as a treatment after the object was made (such as a pesticide) or the result of material degradation (such as the exudation of ...
Also, sodium polyacrylate is a low-cost, non-toxic, and biocompatible option for water purification to recover metal ions. A study demonstrated that a sodium polyacrylate composite had high adsorption and desorption efficiency, implying that sodium polyacrylate can be recycled and reused as an effective absorbent for Cu(II) recovery.

For example, in 1976, the Toxic Substances Control Act (TSCA) was passed. [10] This act called for restrictions on some chemicals, mandatory ingredient reporting, and testing requirements. Some of the chemicals that were restricted included polychlorinated biphenyls (PCBs), asbestos, lead-based paint, and radon. [10]
The Environmental Protection Agency said Tuesday it has finalized a ban on consumer uses of methylene chloride, a chemical that is widely used as a paint stripper but is known to cause liver ...
Powder coating is a type of coating that is applied as a free-flowing, dry powder. Unlike conventional liquid paint, which is delivered via an evaporating solvent, powder coating is typically applied electrostatically and then cured under heat or with ultraviolet light. The powder may be a thermoplastic or a thermosetting polymer. It is usually ...
Trisodium phosphate was at one time extensively used in formulations for a variety of consumer-grade soaps and detergents, and the most common use for trisodium phosphate has been in cleaning agents. The pH of a 1% solution is 12 (i.e., very basic ), and the solution is sufficiently alkaline to saponify grease and oils.
Chloroxylenol, also known as para-chloro-meta-xylenol (PCMX), is a chlorine substituted phenol with a white to off-white appearance and a phenolic odor.. The discovery of chloroxylenol was the result of efforts to produce improved antiseptics that began at the end of the 1800s, when scientists gradually realized that more substituted and more lipophilic phenols are less toxic, less irritant ...
