Normally a reliable source of information, Live Science published an article that is a dream for anti-pesticide and anti-chemical fearmongers.
The recent reporting on Flint's water crisis by CNN's Christiane Amanpour has a tenuous grasp of the data and the reality. 
Forty solid years after the Consumer Product Safety Commission implemented regulations for getting rid of lead-based paint, the US is still on the lead-based paint merry-go-round. Last week, I attended a Congressional hearing entitled “Oversight of the Federal Government’s Approach to Lead-Based Paint and Mold Remediation in Public and Subsidized Housing”, which hoped to figure out how the United States Department of Housing and Urban Development (HUD) can finally be rid of the pesky threat of lead-based paint in federal housing. This comes after the HUD has already spent over $1.2 billion on these exact efforts and have made no measurable progress.
A seven-year study of all Gulf coastal regions maps where fish and other aquatic life live, and in what amounts. This was done in order to give marine biologists a better understanding of the ecological damage that occurred following the 2010 Deepwater Horizon disaster, and to help them better prepare for future spills. 
Also known as dichloromethane, DCM is a colorless liquid with a mild, sweet odor which evaporates easily but does not readily burn. It has a variety of uses, and it is used in the manufacture of photographic film. DCM is made from methane gas or wood alcohol, and it does not occur naturally in the environment.
This very dangerous plant is in the news because it's being increasingly spotted across the United States. But what you probably don't know is that one of the chemicals that makes the plant so dangerous is also a drug that treats psoriasis. 
The online news arm of this journal s a solid source of information. However, it reprinted an article from E&E News that stated green energy is the way to go and the environment is full of scary chemicals. Associating itself with this outlet was a dubious decision, and one that may prove damaging to its reputation. 
Trichloroethylene is a colorless, volatile liquid that is nonflammable and has a sweet odor. It evaporates quickly into the air, but can also be found in water and soil. It also has a variety of uses, which we explain here.
The good news: Aromatherapy won't give you cancer. The bad news: It won't do anything else either. But it is full of chemicals, some of which are considered to be carcinogens. Especially in California.
1,4-dioxane is a clear solvent with a mild pleasant fragrance used in the manufacture of other chemicals, a laboratory reagent, a trace contaminant found in cosmetics, detergents, and shampoos It's also found in some foods, either naturally occurring or as a contaminant.
Summer is approaching, which means that all sorts of life forms will be out to get you. Possibly the worst is poison ivy. It contains a nasty chemical called urushiol, which is perfectly designed to make your life an itchy hell. And it's all because of chemistry.  
The preamble articulates the mission and methods of the agency's Monographs program, and an update has been long overdue. But by doing so, other questions have emerged.
