9/15/2014 - Lead contamination and various other types of pollution have plagued Philadelphia for decades. Dating back to the 1800s, the densely populated city served as a home to a booming industrial district, ripe with a variety of manufacturers including textile mills, chemical factories, ...
Different mechanisms were noted for the impact of microplastics on plant performance, such as serving as root barriers, changing soil microbial structure and metabolism, accumulating in plants, regulating the response of plants to microplastic contamination, etc. Such effects could occur separately or co...
In the context of pollution, thresholds of contamination are often used (Chen, 1999). Likewise, Arshad and Martin (2002) list threshold levels for soil quality indicators, but this is rarely found in other publications on soil quality assessment. For plant nutrients, most agricultural advisory ...
2017). An empty well was left in the plate to control for cross contamination. Test amplification of the 16S V4 region was done using 515F: 5′-GTGCCAGCMGCCGCGGTAA-3′ and 806R: 5′-GGACTACHVGGGTWTCTAAT-3′ with DreamTaq DNA Polymerase (Thermo Fisher Scientific, Waltham, MA, USA)...
Because the area has a history of soil contamination from a former metal smelter, soil testing is provided by the City. Most gardening is done in raised beds, and the mate- rials to construct the beds are provided by the City. Gardeners are also given topsoil amended with biosolids and ...

In contrast, blackleg symptoms were very low in the stock without initial Pectobacterium contamination (EstimaZero). These results, therefore, reinforce the requirement for stringent seed certification for blackleg as even low levels of initial bacterial contamination greatly increased disease incidence. ...
the international research team examined the samples of lunar rock and soil that were returned by the Apollo missions. When these samples were originally examined upon their return to Earth, it was assumed that the trace of amounts of water they contained were the result of contamination from Ea...

Groundwater (GW) constitutes the most important source of drinking water, and despite the benefit of pesticides in food production, the contamination of GW by biologically active pesticides at unacceptable levels should be avoided. A number of pesticides
