The gill monogene communities of Pimephales promelas (fathead minnow) in 3 distinct sites on converging streams were investigated from 2004 to 2006 in 3 different seasons. Thirty collections of P. promelas were made in southeastern Nebraska along 3 converging tributaries: Elk Creek (40.88534 ̊N, 96.83366 ̊W), West Oak Creek (40.9082 ̊N, 96.81432 ̊W) and Oak Creek (40.91402 ̊N, 96.770583 ̊W), Lancast...

Although large loads of potentially toxic constituents are discharged from coastal urban watersheds, very little is known about the fates and eventual impacts of these stormwater inputs once they enter the ocean. The goal of this study was to examine the effects of stormwater discharges on the benthic marine environment of Santa Monica Bay. Sediment samples were collected across a gradient of s...

BACKGROUND Klity Creek has become Thailand's first official remediation ordered by the court in 2013, 15 years after the spill of lead (Pb)-contaminated mine tailing into the creek. The Pollution Control Department (PCD) decided to restore the creek through monitored natural recovery (MNR) since 2006 but has not been successful. Interestingly, the most recent remediation plan in 2015 will still...

Two short sediment cores collected from mangrove areas of Manori and Thane creeks along Mumbai coast were analysed for sediment composition and metals (Fe, Mn, Cu, Pb, Co, Ni, Zn, Cr and V). The statistical analysis of Pearson correlation matrix proved that there is a significant relationship between metal concentration and finer grain size in Manori creek while poor correlation was observed in...

Twenty-eight tidal creeks along the South Carolina coast were sampled during the summer of 1995 to determine the levels of sediment contamination including organic chemicals (i.e., polycyclic aromatic hydrocarbons [PAHs], polychlorinated biphenyls [PCBs], and DDT and its metabolites) associated with different types and varying levels of watershed development (i.e., industrial/urban, suburban, f...

The Amber El Amino area is located 75 kilometres southeast of Prince Rupert. Access to the area is by helicopter from Prince Rupert or Terrace (Figure 1). The El Amino showing (BC MINFILE 103H 071) is located on Sulphide Creek (Figure 2) which drains eastward into Hanna (El Amino) Creek. The Amber showing (BC MINFILE 103H 171) is located 700 metres north of the El Amino showing. Hanna Creek dra...

this study evaluates the influence of yanã½klar creek on the water quality of fethiye gulf. accordingly, this study demonstrates (i) change in the water quality of fethiye gulf from 2006 to 2007; (ii) the water quality classification of the yanã½klar creek feeding fethiye gulf; and (iii) how land-based fish farm influences yanã½klar creek water quality in a fethiye-gã¶cek specially protected ar...

Newtown Creek is an industrial waterway and former tidal wetland in New York City. It is one of the most polluted water bodies in the United States and was designated as a superfund site in 2010. For over a century, organic compounds, heavy metals, and other forms of industrial pollution have disrupted the creek’s environment. The creek is also impacted by discharges from twenty combined sewer ...

The Muddy Creek watershed is a unique ecosystem because the stream contains a distinctive fish assemblage, is physically degraded, and will soon be influenced by oil and gas development. Separating the effects of multiple stressors can be challenging; however, having prior data can be very useful in determining the influence of different stressors. In our study, we attempted to separate the eff...
