Concentrações de amônio na água da chuva e estimativa de emissão de amônia de rebanhos domésticos de Pinheiro e Viana, Baixada Maranhense Rainwater ammonium concentrations and estimate of ammonia emissions from domestic animals in Pinheiro and Viana, Baixada Maranhense

Rainwater samples (bulk deposition samples) were collected in Pinheiro and Viana. Rainwater pHs were higher than the range usually expected for unpolluted rain (5.0-5.6). The highest values were found in the beginning of the rainy season. High concentrations of ammonium found in the rainwater sample...

Summary:Rainwater samples (bulk deposition samples) were collected in Pinheiro and Viana. Rainwater pHs were higher than the range usually expected for unpolluted rain (5.0-5.6). The highest values were found in the beginning of the rainy season. High concentrations of ammonium found in the rainwater samples could probably explain the high pHs. Grazing animals and other human activities, combined with soil characteristics and climatic conditions can be the potential factors controlling the rainwater concentrations of ammonium in Baixada Maranhense.
