“…Water utilities and the scientific community are called to find efficient contaminants' remediation systems in order to improve the performance of treatment plants and deliver safe drinking water to the population. The techniques usually in place include conventional methods such as precipitation, activated carbon adsorption, biological processes, and innovative methods such as advanced oxidation processes, membrane filtration using reverse osmosis, nano-and ultrafiltration processes, and biochar [3,4].…”

Pharmaceuticals and hormones (PhACs) enter the aquatic environment in multiple ways, posing potential adverse effects on non-target organisms. They have been widely detected in drinking water sources, challenging water companies to reassure good quality drinking water. The aim of this study was to evaluate the concentration of sixteen PhACs in both raw and treated drinking water sources in the Metropolitan Area of Turin—where Società Metropolitana Acque Torino (SMAT) is the company in charge of the water cycle management—and evaluate the potential human health risks associated to these compounds. Multivariate spatial statistical analysis techniques were used in order to characterize the areas at higher risk of pollution, taking into account the already existing SMAT sampling points’ network. Health risks were assessed considering average detected concentrations and provisional guideline values for individual compounds as well as their combined mixture. As reported in the just-issued Drinking Water Directive 2020/2184/UE, in order to establish priority substances, a risk assessment of contaminants present in raw drinking water sources is required for monitoring, identifying potential health risks and, if necessary, managing their removal. The results showed negligibly low human health risks in both raw water sources and treated water.

“…Biochar represents a cheaper solution compared to other carbonaceous materials with very promising performances [136,137] due to the several interactions that occur on biochar particles, as summarized in Figure 3. Firstly, biochar has been used to remove persistent small organic molecules such as aromatics.…”

A Review of Non-Soil Biochar Applications

et al. 2020

Biochar is the solid residue that is recovered after the thermal cracking of biomasses in an oxygen-free atmosphere. Biochar has been used for many years as a soil amendment and in general soil applications. Nonetheless, biochar is far more than a mere soil amendment. In this review, we report all the non-soil applications of biochar including environmental remediation, energy storage, composites, and catalyst production. We provide a general overview of the recent uses of biochar in material science, thus presenting this cheap and waste-derived material as a high value-added and carbonaceous source.

“…Furthermore, the OM content of animal manure (e.g., cattle, chicken, horse and bat manures) forms strong complexes with Cd resulting in the reduced mobility of Cd in soil media and reduced leach rate into different soil layers, decreasing both its toxicity and the phytobioavailability of the soil. In one study the application of cattle manure to contaminated soil was found to have resulted in a reduction of Cd leaching by approximately 63% 3 . Many researchers have indicated that leonardite serves as an exceptional substitute for mineral-based fertilizer given that it is rich in humic acid, falvic acid and organic matter (50-75%).…”

The marigolds (Tagetes spp.) in this study, were classified as excluders for cadmium (Cd); however, their leaves also accumulated substantial Cd content. Among the experimental growth media (i.e., control, cattle, pig manure, and leonardite served as soil amendments), pig manure was found to result in significantly increased growth performance for all marigold cultivars, as seen by relative growth rates (119-132.3%) and showed positive effects on leaf anatomy modifications e.g., thickness of spongy and palisade mesophyll, size of vein area and diameter of xylem cells. This may be due to substantially higher essential nutrient content, e.g., total N and extractable P, in pig manure that aided all marigold cultivars particularly the French cultivar which exhibited the highest relative growth rate (132.3%). In the Cd only treatment, cell disorganization was observed in vascular bundles as well as in palisade and spongy mesophyll, which may have been causal in returning the lowest plant growth performances recorded in this study, particularly in the American and Honey cultivars (RGR = 73% and 77.3%, respectively).
