NOTEWORTHY ARCHEOLOGICAL SPECIMENS FROM LOWER COLUMBIA VALLEY

Pesticide multiresidues in waters of the Lower Fraser Valley, British Columbia, Canada. Part II. Groundwater.

In Part I of this work we presented pesticide levels in the surface waters of the Lower Fraser Valley (LFV) region of British Columbia, Canada. In Part II pesticide levels in the groundwater of the LFV are presented. During the period 2003 to 2005 a study was conducted to determine the occurrence and spatial distribution of 78 pesticides in the groundwater of the LFV. Samples were collected and...

Pesticide multiresidues in waters of the Lower Fraser Valley, British Columbia, Canada. Part I. Surface water.

In the period 2003 to 2005, a study was conducted to determine the occurrence, and spatial and temporal distribution of 78 pesticides in surface waters of the Lower Fraser Valley (LFV) region of British Columbia, Canada. A high resolution gas chromatography/electron impact high resolution mass spectrometry (HRGC/[EI]HRMS) method capable of detecting analytes at the subnanograms per liter level ...

Resilience in Lower Columbia River Salmon Communities

In 1992, the first listings of Columbia River salmon under the Endangered Species Act occurred. Regulation of the Columbia River gillnet fishery since that time has greatly reduced fishing time and economic return to the fishing fleet. The counties where two-thirds of the gillnetters reside have registered negative social statistics during this period, including drug and alcohol abuse rates, in...
