Sentence examples for ash contamination from inspiring English sources

In this case the most problematic issue is sewage sludge ash contamination with heavy metals.

To avoid ash contamination, we put the traps in a box that allowed air circulation only through slits in the side of the box.

These insights were supplemented by findings from empirical laboratory experiments, such as the vulnerability of high-voltage transmission insulators to flashover from volcanic ash contamination (e.g. Wardman et al. [2012a]; [2012b]; Wilson et al. [2012b]).

Wardman et al. (2012c) has suggested that 3 mm (3.3 kg/m2 in the case of Shinmoedake tephra) is a lower threshold for insulator flashover following volcanic ash contamination for HV power systems.

As observed for other eruptions with similar urban ashfall thicknesses (Tables 7 and 8), the effect of ash contamination on electrical distribution lines and substation insulators was induced leakage currents and insulator flashover, and the blockage of air intakes at thermal oil and coal fired generation plants (Wardman et al. 2012).

Previous studies have identified the following issues for livestock arising from ash contamination of feed: starvation due to feed becoming unpalatable; gastrointestinal and rumen blockages following ash ingestion; and tooth abrasion (Cook et al. 1981; Cronin et al. 1998; Wilson et al. 2011b).

There are four main impacts arising from ash-contamination of apparatus used in the power delivery process: Wet deposits of ash on high voltage insulators can initiate a leakage current (small amount of current flow across the insulator surface) which, if sufficient current is achieved, can cause 'flashover' (the unintended electrical discharge around or over the surface of an insulating material).

Data quality depends upon the distinction between volcanic ash and contamination by other airborne particulate matter.

I have heard several examples of some of the powerful testimony offered by coal ash victims so far today, including a Pennsylvania woman who presented homemade jam and garden vegetables that were grown with water from her coal-ash-contaminated well, asking the EPA officials whether they would eat the products knowing about the contamination.

In the weeks, months and years after the eruption it became evident that wind-blown ash and household contamination (leading to health concerns) were continuing hazards.

The factors that led to interviewed farmers deciding to evacuate included: homestead roof collapse, or fear it may collapse (Table 2); concerns about health impacts from the ash, including homestead contamination and severe ongoing problems with wind-blown fine ash; fears of further ashfalls; lack of livestock feed following pasture burial and exhaustion of supplementary feed.
