“…This can be especially true for recently developed areas of urban landscapes that can have high rates of overland flow and erosion (Bennett et al 2001;Vaze and Chiew 2004). Other forms of P, such as dissolved organic P (DOP), are not typically examined in urban water samples but are known to contribute significantly to total P (TP) in freshwaters (Bridgeman et al 2012). Despite their potentially important role in P cycling, there is limited information on the prevalence and transformations of P forms including DOP in urban environments.…”

As urban ecosystems are known to be phosphorus (P)-rich environments, the sources of this nutrient and its biogeochemistry within human-dominated landscapes remain in need of study. Specifically, very little is known about how different P species vary within and among urban aquatic environments. In this study, we examined the phosphorus dynamics in urban stormwater ponds that are embedded in residential landscapes. Water samples were collected from stormwater ponds located in southern Ontario, Canada during the summer of 2012. We measured several P types: total P; TP, particulate P; PP, and dissolved inorganic P; DIP as well as two classes of DOP (phosphomonoesters (MP) and phosphodiesters (DP)) in the surface water samples. In most ponds, PP in outflowing water were found at concentrations higher (up to 12 times) than those measured in incoming stormwater. With respect to DOP, DP increased and became more abundant in outflowing compared to inflowing waters while MP concentrations decreased within ponds. The magnitude of these spatial changes from pond inlets to outlets was strongly linked to recent periods of rainfall and the hydrological condition of pond inflows. Elevated MP was found adjacent to inlets especially during periods of more frequent rainfall, which indicates that MP is derived from terrestrial sources and delivered by stormwater. In contrast, DP production was more related to internal biological activity in ponds as its concentrations increased during relatively dry conditions with low stormwater flow. Our results demonstrate that stormwater ponds have significant influence on the quantity and types of P moving through these highly human-modified environments.

“…IP, which accounted for 56-75% of TP in sediments, had the lowest concentration at the point 11 (242.81 mg/kg) and the highest at point 10 (549.73 mg/kg). Generally, Fe/Al-P and OP can release bioavailable forms of P. Especially, Fe/Al-P can easily be released and transformed into active P through chemical and biological reactions, which might influence the overlying water quality [28]. The concentration of Fe/Al-P, accounting for 46-83% of IP in sediments, was minimum at point 11 (112.71 mg/kg) and a maximum at point 10 (455.00 mg/kg).…”

Sediment gradually accumulates at the bottom of reservoirs after decades of running. To explore the influences of sediments on the water quality of reservoirs, the spatial distribution, adsorption/release characteristics, and environment influence of sediment pollutants should be analyzed. In this paper, the spatial distributions of phosphorus (P) and P fractions in the Biliuhe reservoir (river valley reservoirs) sediments were investigated. The adsorption and release characteristics of sediments P were studied in the experiment, while its environmental influence was analyzed too. The results indicate that the concentration of P in sediments was higher at the dam and the Zhongling site, while lower at other entrances of the reservoir and the smallest in the water-level fluctuating zone. Total Phosphorus (TP) varied from 355.46 to 764.57 mg/kg. Inorganic Phosphorus (IP) was the main form of TP in sediments, making up a proportion of 56-75%, while the correlation coefficient of P bound to Al, Fe, and Mn oxides was 0.922. Hydroxide (Fe/Al-P) was the main form of IP, which accounted for 46-83% with a correlation coefficient of 0.888. The maximum adsorption capacity calculated by Langmuir model was between 714.29 and 3333.33 mg/kg. The adsorption efficiency obtained by the Freundlich model was within the range of 0.40-1.42, which indicated that P adsorption was more difficult in the water-level fluctuating zone. The critical adsorption and release concentration range was 0.1-0.2 mg/L for the majority of the sampling points. The amount of P released in 24 h (the initial concentration of TP in the overlying water was 0 mg/L) accounted for 1.15-4.16% of TP in sediments, which was higher than the average concentration in the reservoir. It is concluded that the sediment is the potential pollution source. The relationship between the change of environmental factors and the release of sediment contaminants should be considered in the future.

“…The depths ranged from 0.5 m to 9.5 m, with a variety of substrate types (clay, mud, gravel, sand, etc.,). At each site, five replicate Ekman grabs were collected, and L. wollei in these samples was dried at 70°C to a constant weight and averaged across the five replicates to obtain biomass represented as g m -2 (Bridgeman et al, 2012). During 2009, dreissenid shells found in the samples were not categorized as dead or alive.…”

“…Abundant C. glomerata can lead to problems such as decreased esthetic value and recreation, human health risks, and altered food web structure (Bootsma et al, 2005), while the same issues occur with L. wollei, including the capability of producing toxins (Carmichael et al, 1997). Unlike C. glomerata, L. wollei does not attach to hard substrates; it becomes partially covered in sandy or dreissenid shell substrate (Bridgeman et al, 2012). L. wollei also differs from C. glomerata in that it grows well in low light (Dyck, 1994).…”

Dreissena spp. (zebra and quagga mussels) are invasive to North America and increase light to the benthos, provide hard structure for algal attachment, and may contribute limiting nutrients to benthic algae, thereby facilitating algal blooms. We conducted experiments to determine how Dreissena affect nutrient stoichiometry and growth of Lyngbya wollei and Cladophora glomerata, two benthic algal species recently increasing in biomass in parts of the Laurentian Great Lakes, combined with a field survey to determine the likelihood of L. wollei co-occurrence with Dreissena. L. wollei had a significantly higher concentration of carbon, nitrogen, phosphorus, potassium, and sulfur when grown with live Dreissena. C. glomerata had greater biomass in tanks with live Dreissena, but did not have significant increases in nutrient concentration like L. wollei did. Neither algal species increased in growth due to the added structure of Dreissena shells. L. wollei biomass was greater in the presence of Dreissena during 1 year (of two) of our field survey. This field survey also showed that L. wollei and Dreissena are likely to co-occur. These results suggest that Dreissena provide several nutrients to benthic algae, and these added resources can promote algal growth and consequently blooms.
