When a teacher overhead elementary students talk about having nothing to eat, a call went out for someone to run a weekend food program.
Ortho-PCBs may alter hormone regulation through disruption of the thyroid hormone transport by binding to transthyretin. [8] Coplanar PCBs are similar to dioxins and furans, both bind to the aryl hydrocarbon receptor (AhR) in organisms and may exert dioxin-like effects, in addition to the effects shared with non-coplanar PCBs.
The act also provided Federal funding assistance towards non-food purchases for school equipment. The act established the School Breakfast Program, a federally assisted meal program that provides low-cost or free breakfasts to children in public and non-profit schools as well as child care institutions.

Exposure to the coplanar stereoisomer 3,3',4,4',5,5'-hexabromobiphenyl (but not the non-coplanar stereoisomer) in genetically susceptible mice is known to cause immunotoxicity and disorders related to the central nervous system, and even at doses as low as 2.5 mg/kg, excess neonatal fatalities are observed (LD 50 is from 5–10 mg/kg).

An example is the co-evolution of the production of tetrodotoxin in the rough-skinned newt and the evolution of tetrodotoxin resistance in its predator, the Common Garter Snake. In this predator–prey pair, an evolutionary arms race has produced high levels of toxin in the newt and correspondingly high levels of resistance in the snake. [4]
(Reuters) -A Washington jury on Tuesday ordered Bayer to pay $100 million to four people who say they were sickened by toxic chemicals known as PCBs at a Seattle-area school, but found the company ...
