    Chemicals in biodegradable food containers can leach into compost

    Composting biodegradable food containers cuts the amount of trash that gets sent to a landfill. But the practice may serve up some unintended consequences for human health.

    That’s because the items often contain perfluoroalkyl and polyfluoroalkyl substances, or PFAS, to help repel water and oil. These persistent chemicals can leach out of the packaging and end up in compost, researchers...

  • 50 years ago, DDT pushed peregrine falcons to the edge of extinction

    Fierce and swift, steel blue in color and called the world’s most perfect flying machine, the peregrine falcon is heading toward extinction in North America. The reason: DDT. Perilously high levels of the pesticide and related chemicals have been found in the eggs, fat and tissues of the birds…. [The falcons] are not picking up the DDT directly, but get it by eating other birds which...

    An acid found in soil may make a disease killing deer less infectious

    An acid found in rich humus soil breaks down the misfolded brain proteins — called prions — that cause chronic wasting disease.

    When concentrations of humic acid similar to those found in soils were applied to diseased elk brain tissue, chemical signatures of the infectious prions were nearly erased, researchers report online November 29 in PLOS Pathogens. That suggests that the acid...

    A ghost gene leaves ocean mammals vulnerable to some pesticides

    A gene that helps mammals break down certain toxic chemicals appears to be faulty in marine mammals — potentially leaving manatees, dolphins and other warm-blooded water dwellers more sensitive to dangerous pesticides.

    The gene, PON1, carries instructions for making a protein that interacts with fatty acids ingested with food. But that protein has taken on another role in recent decades...

    Pediatricians warn against chemical additives in food for kids

    The American Academy of Pediatrics is cautioning parents and pediatricians to avoid exposing children to eight chemicals found in food and in plastic packaging. The chemicals may be especially harmful to kids due to their small size, says the report published July 23 in Pediatrics. Pregnant women should also avoid the chemicals. And lower-income families who eat a lot of prepackaged foods...

    ‘The Poisoned City’ chronicles Flint’s water crisis

    The Poisoned CityAnna ClarkMetropolitan Books, $30

    America is built on lead. Networks of aging pipes made from the bluish-gray metal bring water into millions of U.S. homes. But when lead, a poison to the nervous system, gets into drinking water — as happened in Flint, Mich. — the heavy metal can cause irreparable harm (SN: 3/19/16, p. 8). In The Poisoned City, journalist Anna Clark...
