Initiation and development of the industries producing specialty starches, modified food starches, high-fructose sweeteners, and food gums (hydrocolloids) over the past century provided major ingredients for the rapid and extensive growth of the processed food and beverage industries. Introduction of waxy maize starch and high-amylose corn starch occurred in the 1940s and 1950s, respectively. D...

Tropospheric reactive gaseous chlorine (Cly) impacts the atmosphere's oxidation capacity with implications for chemically reduced gases such as methane. Here we use Greenland ice-core records of chlorine, sodium, and acidity, global model simulations to show how tropospheric Cly has been impacted by anthropogenic emissions since 1940s. We that contribution nonsea-salt significantly influenced t...
