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...

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...

The bioavailability of methylmercury (MeHg) in the brains of  orange spotted groupers, captured from four creeks of Mahshahr embayment was measured.  Then the effects of this pollutant on the regulation of gene expression, acetylcholinesterase transcript levels was chosen in order to monitor the amounts of methylmercury concentrations in the creeks, and the fluctuations of mRNA expressions in t...

background: musa creek, suitable place for spawning of many fish species and other organisms, is one of the most important and voluble ecosystems in the west of iran that received so many attentions due to existents of various industries around this part of persian gulf. previous studies confirmed that marine fish have collected high amounts of pollutants in this area which could be lead to sev...

Before 1909, atoms were thought to consist of a diffuse positive charge surrounded by electrons (the “plum pudding” model). In order to predict the properties of the elements on the periodic table with this model, the distribution of electrons on a sphere had to be studied. This problem was named after Thomson, the originator of the plum pudding model and the first to study it. In 1909, Rutherf...

Speciation and reactivity of mercury were examined in Berry's Creek estuary downstream of a highly mercury-contaminated U.S. EPA Superfund site during the summers of 2002 and 2003. Surface water samples from Berry's Creek estuary, its confluence with the Hackensack River, and upstream of that confluence were analyzed for total (THg), particulate (PHgT), and dissolved (DHg) mercury, total and pa...
