Eutrophication vegetation

Aquatic safety factors ranged from 5.5 X 107 for rainbow trout in ponds to 9.3 X 108 for daphnia in lakes. These data emphasize that exposure levels of CGA-72662 are low and must be taken into account for a risk assessment. Although the persistence of CGA-72662 in eutrophic lakes is relatively long, the exposure is extremely low and of no environmental consequence. Overall, use of SWRRB runoff and EXAMS models show CGA-72662 to be very safe in aquatic habitats when used on vegetables in Florida muck soil. 

Source Field et al. (1998). After Field et al. (1998). All values in GtC. Ocean color data are averages from 1978 to 1983. The land vegetation index is from 1982 to 1990. Ocean NPP estimates are binned into three biogeographic categories on the basis of annual average Csat for each satellite pixel, such that oligotrophic = <0.1 mg m, mesotrophic = 0.1 < < 1 mg, and eutrophic = > 1 mg m (Antoine etal., 1996).

The biggest problem is that the materials applied to the lawn do not necessarily stay there when it rains or the lawn is overwatered. They can go into groundwater or into streams. The result can be loss of aquatic vegetation and animal life in streams and lakes from the herbicides and insecticides, as well as eutrophication, which often involves growth of undesirable species, from the fertilizer. The result may well be a loss in biodiversity. Biodiversity can also be lost if native wild flowers and shrubs are replaced by lawn, as often happens. (The lawn is a biological desert of a few species of Eurasian grasses.305)... 

Excess amounts of nitrates in surface waters disturb natural equilibria and when present in drinking water, they are also hazardous to human health. In the presence of phosphates, nitrates cause eutrophization overpopulation of aquatic vegetation, which reduces the oxygen content in water during its decomposition, and later leads to the production of ammonia, thus threatening the life of aquatic organisms. 

The Bay of Quinte is a shallow eutrophic embayment on the northeastern shore of Lake Ontario. A wildlife habitat enhancement project was recently implemented, in 1985 through 1987, in Big Island Marsh of this bay. The project required the annual cutting of several kilometers of channels through dense aquatic vegetation (i.e. cattails). In total, approximately 10% of the cattails in the marsh were removed in an effort to create open-water habitat for ducks, geese and muskrats and to increase aquatic tracheophyte diversity (E. Lander, pers.
