Shrimp farming is booming along tropical coasts, but scientists still argue over whether these operations leak harmful metals into nearby mangrove swamps. A recent study took a close look at Todos os Santos Bay in Brazil, where shrimp ponds sit right next to mangroves. Researchers tested mud from th
Big cities often promise excitement, but they also bring dirty air. Now a large study in the UK is asking if breathing that air for years might harm the nerves in our bodies. Scientists tracked thousands of adults over time to see whether heavy exposure to tiny floating particles and gases from traf
Scientists recently found traces of PFOS, a long-lasting chemical, inside honey and the bees that make it. These substances stick around in nature for years, building up in the environment and even inside living things. For bees, even small doses can mess with their growth. Young bees exposed to PFO
Scientists tested water in Brazil’s Protected Areas and found pesticide pollution almost everywhere. Samples from streams inside conservation zones and outside showed high traces of farm chemicals. The study tested 46 substances and spotted 15 types, including common herbicides, insecticides, and fu
A recent series of air attacks on oil storage sites in Iran triggered a strange weather event that left the capital drenched in dark, sooty rain. Normally, rainfall clears air pollutants, but this time the drops carried a heavy mix of soot and carbon particles that settled on buildings and streets.
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
East Asian cities are breathing in more than just the night air. Smog, dust, and fumes from factories, traffic and coal plants mix into a harmful cocktail that harms every part of the body. Studies show people in these regions are more likely to suffer from heart attacks, asthma, and even brai
A recent inspection by the Maryland Department of the Environment found that paint fragments falling from Baltimore’s 28th Street Bridge carry dangerous levels of lead. The agency was alerted after residents noticed orange and white debris along Falls Road, near the 2700 block. Tests confirmed that
Maine's air quality is in trouble. The Environmental Protection Agency (EPA) has decided to undo a key rule that limits greenhouse gas emissions. This rule was put in place in 2009 to protect public health. Now, with this rule gone, Maine might see more pollution coming from other states. Maine alr
Life in a bustling city like Hanoi is full of energy, culture, and amazing food. But from October to March, the air quality takes a hit. The Air Quality Index (AQI) often soars, making it hard to breathe without a mask. On rare days when the AQI dips below 100, it feels like a gift. The air might st
