The relationship between bacterial concentrations in wastewater used for spray irrigation and in the air was examined. Aerosolized coliforms were detected when their concentration was 10(3)/ml or more in the wastewater. Relative humidity and solar irradiation appeared to affect viable bacteria in the air; a positive correlation was found between relative humidity and the number of aerosolized bacteria. The correlation between solar irradiation and bacterial level, on the other hand, was negative. During night irrigation, up to 10 times more aerosolized bacteria were detected than with day irrigation. Wind velocity did not play an important role in the survival of aerosolized bacteria. Echovirus 7 was isolated in 4 out of 12 air samples collected 40 m downwind from the sprinkler.
研究了用于喷灌的废水中细菌浓度与空气中细菌浓度之间的关系。当废水中的大肠菌群浓度达到10³/ml或更高时，可检测到气溶胶化的大肠菌群。相对湿度和太阳辐射似乎会影响空气中的活菌；发现相对湿度与气溶胶化细菌数量之间呈正相关。另一方面，太阳辐射与细菌水平之间的相关性为负。夜间灌溉期间检测到的气溶胶化细菌比白天灌溉时多10倍。风速在气溶胶化细菌的存活中未发挥重要作用。在距喷头40米下风处采集的12个空气样本中，有4个分离出了埃可病毒7。
