Synopsis: |
Perception of risk is an important component of risk reduction. This paper for the first time conducts a comprehensive study on the ecological risks of various persistent organic pollutants (POPs) in the Haihe River, China. Due to the past industrial activities, the relatively high risk levels were found for such POPs in this area. This study is helpful for the management and control of POPs in the Haihe River, aiming to minimize their risk. |

Synopsis: |
We investigated the nitrate, sulfate, total dissolved solid, electrical conductivity, total hardness, and bicarbonates of rainwater samples collected from Warri and Port Harcourt (oil-producing), and Awka (non-oil producing as control), between April–June, July–August, and September–October of 2005 and 2006 to depict the onset of the rainy season, mid-rainy season, and end of rainy season for the two major crude oil–producing cities of the Niger Delta region of Nigeria (although Port Harcourt is also noted for non-oil manufacturing industries). Anthropogenic activities in the Niger Delta impacted on the inorganic ion pollution of the rainwater. This may have serious public health implications in the region. |

Synopsis: |
A 30-year trend of increasing groundwater nitrate-nitrogen concentrations in a portion of Nebraska’s intensively cropped and irrigated central Platte River valley reversed after the imposition of enforceable management regulations. Increased sprinkler irrigation and improved yields (N removal) appear to account for more than 70% of the decrease in groundwater nitrate concentrations. The slow rate of nitrate decrease indicates that additional decades of management improvements are needed before compliance with the drinking water standard can be attained. |

Synopsis: |
This study shows how remote sensing and geographical information systems are important tools for determining and updating land use/land cover changes at water basin areas and how water quality measurements at station points can be correlated with spectral reflectance values derived from satellite imagery via regression analysis. Good correlation of observed satellite reflectance with water quality parameters presents that remotely sensed data provide a useful index for water quality parameters. |

Synopsis: |
L-carnitine is a nonessential organic nutrient that is required for the entry of long-chain fatty acids into mitochondria for â oxidation. L-carnitine serves as a growth promoter, helping in the utilization of high fat levels in the diet and thus providing a protein-sparing effect. The objective of this study was to assess the effects of dietary protein and L-carnitine levels on blood sugar and lipids of juvenile new GIFT strain Nile tilapia (Oreochromis niloticus). Results from this experiment suggest that high levels of dietary protein and L-carnitine supplementation could reduce the burden of fish liver as a result of the reduction in plasma lipids. |

Synopsis: |
In this study, we examined the export of dissolved organic carbon (DOC) from a 3,700-ha ponded freshwater marsh through which Mississippi River water is diverted into the Louisiana Barataria Basin estuary. DOC concentration in water leaving the freshwater wetland was elevated in relation to water entering the ponded wetland. This study clearly demonstrated that the freshwater marsh in upper Barataria Basin supplies a significant amount of DOC concentration to the lower estuary. |

Synopsis: |
This review identifies problems, finds general patterns, and extracts recommendations for successful management using nontraditional biomanipulation to improve water quality. Both enclosure experiments and large-scale observations reveal that the initial phytoplankton community composition greatly impacts the success of biomanipulation. Nontraditional biomanipulation is only appropriate if the primary aim is to reduce nuisance blooms of large algal species, which cannot be controlled effectively by large herbivorous zooplankton. However, this type of biomanipulation did not work efficiently in less eutrophic systems where nanophytoplankton dominated. |

Synopsis: |
Environmental pollution, a known feature of the crude oil–producing area of Nigeria, has led to social agitation, claims, and counter claims. We have measured the acidity of rainwater in two major cities within the oil-producing areas and compared it with Awka, a city not connected with oil exploration activities. Our results suggest that oil exploration may contribute to the precipitation of acid rain. |

Synopsis: |
We evaluated the relationship between TN:TP ratio and Microcystis growth via a database that includes worldwide lakes based on four types of lake origin (dammed, tectonic, coastal, and volcanic lakes). The relationship between TN:TP ratio and Microcystis growth could be explained by the nutrient elution tests under controlled TN:TP ratios through the various sediment treatments. The origin rather than trophic state for lakes could be considered as an important factor of TN:TP influences on Microcystis growth. |
