Sentence examples for downstream sampling from inspiring English sources

In general, river water samples upstream of urban discharges presented lower human viral loads than downstream sampling sites, and those differences appeared to increase with urban populations but decrease in response to high river flow, as the elevated river water volume dilutes microbial loads.

However, elevations for downstream sampling sites, especially during high-flow season, were apparent as compared to the value obtained for fish muscle sampled from the reference site A. The RNA content differed significantly in different seasons and it decreased for the downstream sites.

We used the lower and upper end of these ranges for nutrients expected to be limiting to establish downstream sampling sites (SW1 and SW2) in treatment streams.

To complement longitudinal (downstream) sampling, transverse (upslope from the river) patterns in vegetation and substrate would also be inventoried to provide yet another form of spatial analysis, revealing correspondence between water-levels, substrate, and vegetation.

Upstream samples yielded significant (P<0.05) C. dubia toxicity and reproduction impairments, while downstream samples only yielded reproduction impairments.

The primary trend that emerged from each basin was a significant 15N enrichment of all ecosystem components at near-canal sites, relative to more downstream sample sites.

Results were obtained from directly within the treatment pod (shown in Fig. 6), as it was envisaged that mixing of untreated water in direct connectivity with the downstream samples would mask some of the removal taking place by reintroducing metals to the treated water.

Each basin has unique landscape variables, geology, hydrology, precipitation, and land use, which is reflected in the pesticide content at the most downstream sample site near the mouth of the Mississippi River.

The system was designed to store resulting data in a relational database, amenable to downstream sample interpretations and databasing applications following the most recent guidelines in nomenclature for sequenced alleles.

The clear effects of upgrading the WWTP with ozonation, more specifically the increase in vulnerable species in downstream samples from 18 to 30%%, would correspond to a reduction of toxicant loads by approximately 1.5 toxic units (Daphnia magna) according to the regressions in [21].

This solid phase design also benefits the downstream sample processes.
