During rainy periods soil nitrogen in the soil is channeled into rivers, contributing to their contamination, a research from Nagoya University has found. The investigation thus denies the theory of atmospheric origin of water pollution<\/h2>\n

Nitrogen that contributes to pollution in waterways during rainy periods comes from the soil, not the sky according to a research<\/a> by a team of scientists from Nagoya University<\/strong> in Japan. “Nitrate is an essential nutrient for plants and phytoplankton,” the authors explain<\/a>. “But excessive nitrate<\/strong> levels in streams can damage water quality, cause eutrophication (the over-enrichment of water by nutrients), and pose health risks to animals and humans.”<\/p>\n

However, what are the causes of this phenomenon? There are basically two hypotheses. The first involves nitrates in the soil<\/strong> that washes into streams; the second assumes that nitrogen compounds from the atmosphere<\/strong> dissolve with rain, precipitating into rivers and streams. The study by the Japanese team refutes exactly this second theory.<\/p>\n
