The average surface water quality parameters of rivers and reservoirs were analyzed separately during pre- and post-monsoon periods to ascertain the trend of contaminations (Fig. 5a, b).
Temporal trends of contamination were greatest in sediments collected from areas near the Hyperion Treatment Plant (HTP) outfall system and on the slope of Redondo Canyon.
Groundwater ages provide insight into timescales and trends of contamination, recharge rates, and resource characterization, which in turn is useful for understanding aquifer and PSW vulnerability.
> The data generated by chemical analytical and bioanalytical methods for PCBs/OCPs are often used to assess spatial and temporal trends of contamination in environmental media on a national, regional and international basis.
This temporal trend of groundwater contamination underscores the need to prevent acid mine water to penetrate the aquifer to protect groundwater resources.
Immediate measures are required to stop the current trend of groundwater contamination through protection of recharge basins and improve onsite sanitation systems.
However, there was a trend of higher contamination on the flanks as compared to foreleg, brisket and rump on both markets.
This information will also appeal to the wide audience and institutions responsible to regulate the introduction of waste into Lagoons knowing that the trend in levels of contamination varies at different climatic/environmental conditions.
Due to increasing trend of Cd environmental contamination and human exposition, our findings are of high importance and could also have practical implications in humans.
Results: Although there was a trend toward lower rates of contamination in the group that did not wear a covering garment, the difference was not significant.
