Ammonium, nitrite, nitrate and phosphate fluxes across the sediment-water interface in a tropical lagoon

Abstract: Recibido en septiembre de 1993; aceptado en enero de 1994 RESUMENSe realizó un estudio en los sedimentos de la Laguna Chelem, situada en el litoral del Golfo de México, al norte de la Península de Yucatán (México), midiendo la concentración de nutrientes en el agua intersticial. El amonio tuvo un máximo de 1,045 PM, con valor medio de 459 k 281 PM; el nitrito alcanzó 5.3 PM, con valor medio de 1.8 f 1.8 PM; el nitrato se encontró en concentraciones de hasta 34.7 PM, con valor medio de 8.2 f 10.3 PM, y el fosfa… Show more

“…The flux of nutrients from the sediment into the water column depends on factors such as concentration gradient and bioperturbation, and fluctuates between 0.07 and 6.72 mg N L −1 day −1 (e.g. Krom & Berner 1980; Schroeder 1987; Blackburn & Henriksen 1983; Seitzinger 1988; Valdés & Real 1994). Estimates of total ammonia nitrogen (TAN, NH 3 ‐N+NH 4 + ‐N) flux from marine and freshwater sediments into the overlying water vary between 0.03 and 22 mg N m −2 day −1 (Boynton, Kemp & Osborne 1980; Brannon, Chen & Gunnison 1985).…”
