Bioavailability of Phosphorus Inputs to Lakes

Abstract: Interpretation of the potential bioavailability of phosphorus forms and fractions indicates some of the P entering lakes may have a limited effect on lake productivity. Some P sources, such as land runoff, are often high in particulate P, significant portions of which cannot be utilized in the growth of algae and higher plants. Based on existing information (mostly from Great Lakes studies), potentially bioavailable P in tributaries generally does not exceed 60% of the total P and is often considerably less. P… Show more

“…This result indicates that forms of phosphorus on the plume particles may be very distinct from those in the open lake. The NaOH extraction has been shown to be a good indicator of the amount of P which may be biologically available in sediments (Sagher et al 1975) and represents non-apatite inorganic forms of P typically associated with Al and Fe hydrous oxides (Sonzogni et al 1982). One possible explanation for the higher plume APP would be rapid adsorption of dissolved P by the clay particles.…”

“…Essas partículas e compostos são muito ativos quimicamente e, por isso, em geral são enriquecidos de elementos minerais adsorvidos. Por isso, tais frações constituem causa da eutrofização dos mananciais de água onde elas se depositam Sharpley et al, 2001), principalmente porque parte dos elementos minerais que enriquecem quimicamente esses sedimentos encontra-se numa condição de biodisponibilidade para os organismos aquáticos, conforme argumentado por Sonzogni et al (1982).…”

“…The influence of episodic sediment loading on phytoplankton communities varies with the composition, aging, chemical history, and loading rates of incoming soil (Sonzogni et al 1982;Cuker et al 1990) and algal species, physiological condition, and ion content of the water (Avnimelech et al 1982;Soballe and Threlkeld 1988). There are conflicting conclusions about the influence of sediment loading on phytoplankton communities and uncertainty about overall effects of suspended sediments on the community structure and physiology of phytoplankton in receiving waters (Hunter and Liss 1982;Fox et al 1985;Threlkeld and Soballe 1988;Cuker et al 1990).…”

“…The turbidity also reduces light penetration and alters nutrient availability (Sonzogni et al 1982;Grobbelaar 1983;Kimmel et al 1990). Phosphorus, for example, may be adsorbed to incoming particulates (Froelich 1988), but the suspended sediments may sequester phosphate so that the algae experience greater nutrient limitation as a net outcome (Heath and Francko 1988).…”
