Scientist are racing against time to produce a strain of wheat that will survive the coming drought and substantially more challenging weather climate change is bringing. Wheat is one of the most vital, staple plants we consume around the world. Right now, we are going back to the roots of wheat development to find sturdy strains that were bred out of use because of commercialization.
In the News: Stain-Proof, Water-Proof, PFAS
PFAS is dominating the News as an analysis of popular brand names claiming to be stain or water resist reveals 75% percent of them contain PFAS. An excerpt from article found in “The Guardian” had this to say:
When you have these products indoors, depending on how many PFAS treated products you have, there will be high levels of PFAS in your indoor air.
The chemicals also can also be absorbed through the skin and are a problem for workers in textile factories, where researchers have found high exposure rates.
This from Erika Schreder, a co-author of this study and the Science Director of Toxic Free Future. Toxic Free Future is based in Seattle and you can check them and the work that they do out here.

In the News: Biosolid Pollutants
Johns Hopkins is involved in the analysis of biosolids and the assessment of the inherent health risks it may cause the public.
Biosolids are created during the wastewater treatment process. When biosolids are spread on agricultural land, they add nutrients, improve soil, and enhance moisture retention. Applying biosolids to land has economic and waste management benefits, since it saves space in landfills, recycles a waste product, and reduces demand for synthetic fertilizers.
Biosolids can also contain a variety of pollutants. Some of the main offenders: per- and polyfluoroalkyl substances, or PFAS, which are found in non-stick cookware, carpets, and food packaging; triclosan, an antimicrobial found in personal care products; and unmetabolized pharmaceuticals.
The Johns Hopkins team was granted $1.87 million dollars by the EPA to study sewage and are using toxicology to provide utilities and state with guidelines to ensure that they process and handles biosolids in the least harmful way.
Since the banning of ocean dumping in 1991, biosolids have been increasingly applied to agricultural land, forests, parks, golf courses, home gardens, and lawns.
"We know very little about the organic chemical contaminants in biosolids," Prasse says. "This information is critical to the development of strategies to understand exposure and potential public health risks."
Carsten Prasse, the team lead says that this problem goes beyond biosolids alone and we need to focus on the big picture as well. The best approach may be to try and stop some of these chemicals at the source, before they even research treatment facilities and are incorporated into biosolids.
