“…This trend confirms that leaching components migrate from the same source [40]. Markedly, the concentration of leachable volatile compounds increases with extended stagnant time [41,42]. Even though the levels of some of the organic components identified in this migration experiments are below the permissible limit of MCL, their prolonged exposure can pose danger to human health [35,43].…”

It is well established that the use of synthetic material in water pipes significantly affects the quality of domestic water, especially trace organics that are leached through with the flow of water. In the present study, the migration of volatile organic compounds (VOCs) from water pipes manufactured of polyvinyl chloride (PVC) has been investigated using static laboratory conditions and in residential areas. The contact of deionized water with various PVC pipes for three successive test periods of 24, 48, and 72 h duration has been made. Twenty water samples were collected from houses within Medina Al-Munawarah residential area and were analyzed by using solid phase extraction, followed by high resolution gas chromatography with flame ionized detector (GC-FID). The presence of carbon tetrachloride (CTC), toluene, chloroform, styrene, o-xylene, bromoform (BF), dibromomethane (DBM), cis-1,3-dichloropropane (Cis-1,3-DCP), and trans-1,3-dichloropropane (Trans-1,3-DCP) was initially confirmed. The most frequent contaminants found were DBM, CTC, and toluene that were monitored in 55%, 50%, and 45% of samples, respectively. The levels of CTC, Cis-1,3-DCP, and Trans-1,3-DCP were found to exceed the World Health Organization (WHO) limits in 50%, 20%, and 20% of samples, respectively. The migration test indicated that nine of the targeted contaminants occur in a double distilled water sample incubated in pipe in laboratory level experiment. This implies that these components are more likely to migrate from PVC pipe in home plumbing systems network.

“…A result of the use of biomass for energy generation is the production of large amounts of ash during incineration. Ash is frequently considered an unwanted product because of its toxic elements, such as Cd, Ni, Pb, Cr, Zn, Co, and Cu (Maresca et al 2018;Munda et al 2016;Noyce et al 2016); therefore, large quantities of generated ash are regularly applied for landfills (Careddu et al 2015;Valentim et al 2019). Ash also contains major nutrients required by plants, except for nitrogen, and has liming properties due to its high contents of metal oxides and hydroxides (Maresca et al 2019;Qin et al 2017;Silva et al 2019).…”

Ash resulting from biomass energy resource utilization contains a wide range of metal oxides and hydroxides, which may influence the capacity of the ash to be used as a soil amelioration material. This study aimed to assess the effects of different ashes on changes in soil carbon (C) mineralization and soil microbial biomass carbon (MBC) in reclaimed mining soils (RMSs). Different levels (0, 25, 50, and 75 Mg ha −1) of three ashes (rice husk, oil palm shell, and coal fly ash) were applied to 10-year RMS for a 120-day incubation period. Carbon mineralization was measured over the 120-day incubation period, while MBC and selected chemical properties were quantified at the end of the incubation period. The results of the study showed that the application of rice husk and oil palm shell ash at all levels and coal fly ash at low levels (≤ 25 Mg ha −1) increased C mineralization and MBC. However, the C mineralization and MBC of the soil decreased significantly when the amount of added coal fly ash reached 75 Mg ha −1. These decreases in C mineralization and MBC may be ascribed to the harmful effect of high amounts of coal fly ash on microbial activity and the increased specific surface areas and contents of Ca, Mg, oxalate-and dithionite-extractable iron and aluminum in soil with high amounts of added coal fly ash. This study demonstrates that the application of different types of ash to RMS leads to different C mineralization and soil MBC responses.
