Polyacrylamide, a water‑soluble polymer widely used in industry, usually breaks apart when exposed to free radicals. Traditional studies assumed that the main reaction was chain scission, where long polymer chains split into shorter pieces. Recent experiments with persulfate as a radical source reve

Nanoplastics are tiny bits of plastic that are causing big problems in water environments. They often get weathered by the sun, making them even more harmful. Fish, which can usually heal their tails pretty well, are now struggling because of these aged nanoplastics. Scientists did an experiment wi
America's farmlands are facing a serious issue. Sewage sludge, often called "biosolids, " is being spread on fields as fertilizer. This sludge contains harmful chemicals and waste from homes and industries. The EPA allows this practice through a rule called the 503 rule. This rule does not make the
China's farms are a major source of pollution, contributing to 17% of the country's greenhouse gas emissions. However, the need to increase food production presents a challenge. The tools farmers use, such as tractors, pesticides, fertilizers, and plastic sheets, play a significant role in this dile
America's factory farms, or CAFOs, produce a staggering amount of waste. This waste often ends up in our rivers and lakes, making them unsafe for swimming or fishing. The problem is that these farms are not held to the same environmental standards as other industries. Unlike factories, they don't ha
