The evidence of the impact of the mismanagement of plastic goods in the environment has captured the attention of scientists, policy makers and manufacturers. Urgent measures, regarding a combination of preventing plastic use and massively improving waste management, have been acclaimed by different stakeholders with the common goal to make a more resilient and competitive plastic industry. European Commission has pledged itself publishing the first EU-wide policy framework on plastics. The new recycling targets and calculation method put under pressure the current waste management system (WMS), characterized by fragmentation in responsibilities and underperforming cost-benefit balance. In addition, the public-private governance and the increasing number in waste consortia and platforms contribute to make the waste streams traceability challenging. The following study, resulting from a collaboration between the University of Bologna (UNIBO), the Emilia-Romagna Region (ERR), and the Regional Agency for Prevention, Environment and Energy (ARPAE), investigates the current panorama of plastic waste recycling system in ERR (Italy) with the aim to find out to what extent the current performance fulfils the future scenario established by the European Commission. The market of secondary plastics (SPs) has been investigated as well. The secondary resources, which are no longer waste, are not registered and monitored by official data collection scheme. Data extrapolated from official waste databases are integrated with results coming from individual questionnaire submitted to local recyclers. The identification of the main polymeric streams and, therefore, the exploitation of economic potential represent the preliminary actions to strategically plan an after-use plastic economy whose main goal is having all recyclable and/or recycled plastic packaging by 2030.During drinking water treatment processes, anthropogenic compounds act as important precursors of disinfection by-products such as haloacetic acids (HAAs). Several transformations in these precursors occur prior to the disinfection stage, such as partial biodegradation. We hypothesized that this partial biodegradation of anthropogenic compounds potentially affects their HAA formation potentials (HAAFPs). In this study, the HAAFPs of 51 anthropogenic compounds after short-term contact (less than 1 h) and long-term contact (24 h) with activated sludge were compared. Considerable changes were observed particularly in trichloroacetic acid (TCAA) formation potentials (FPs) of phenols, demonstrating that biodegradation should be considered in investigations of potential precursors of HAAs. Phenols with low HAAFPs, such as hydroquinone, show higher HAAFPs after biodegradation, but HAAFPs of most phenols and anilines decreased after biodegradation. Thus, biodegradation will most likely have a positive impact on water quality from the standpoint of HAAFP reduction. For most aliphatic compounds, changes in HAAFP were negligible, but the dichloroacetic acid (DCAA) FP of acrylic acid largely increased. This study illustrates that biodegradation may have a large effect on the HAAFPs of anthropogenic compounds.The fluidity of arsenic (As) in soil used for rice cultivation under flooding conditions is the main reason for its high accumulation in rice, which poses a serious threat to human's health. Biochar can immobilize heavy metal (for example lead) of soil because of the strong binding of heavy metals to the inner biochar particles. We conducted a pot experiment to evaluate the effects of biochar (BC) and Fe-Mn-Ce oxide-modified biochar composites (FMCBCs) on the morphology, As accumulation, and grain quality of rice grown in As-contaminated soils. The biochar and FMCBC treatments significantly increased the dry weight of roots, stems, leaves, and rice grains grown in As-contaminated soil (P  less then  0.05). The As concentration in different parts of rice was significantly lower with treatment FMCBC3-2 (BC, Fe, Mn, and Ce weight ratio of 242310) than with the BC and control (no BC) treatments. The application of FMCBC3-2 maximized the yield and quality of rice grains rice grain yields were 61.45-68.41% higher over control and the proportion of essential amino acids in the rice grains was 31.01-44.62%. The application of FMCBCs also increased the concentration of Fe-Mn plaques, which prevent the uptake of As by rice, thereby mitigating the toxic effects of As-contaminated soil on rice. In summary, Fe-Mn-Ce oxide-modified BC composites fixed As, reducing its fluidity and the As concentration in rice. Our results show that FMCBC3 could play an important role in reducing As accumulation and increasing the grain yield and quality of rice, thus ensuring food safety in regions contaminated with As.In the context of the water environmental protection and local economic sustainable growth, it is of great importance to conduct a comprehensive water quality assessment in Chaohu Lake basin. In this study, dissolved oxygen (DO), permanganate index (CODMn), 5-day biochemical oxygen demand (BOD5), ammonia nitrogen (NH3-N), total nitrogen (TN), and total phosphorus (TP) were investigated monthly at 24 sampling sites in Chaohu Lake basin during 2015 to 2017. https://www.selleckchem.com/products/sodium-succinate.html Five methods were used to evaluate water quality and identify dominant pollutants. Results showed that the dominant pollutants in Chaohu Lake were TN (4.17~11.61 mg L-1) and TP (0.27~0.75 mg L-1). The upstream of Chaohu Lake was influenced by Nanfei River, Shiwuli River, and Paihe River, and water quality of the upstream (eutrophic) was worse than that of the downstream (mesotrophic) part of Chaohu Lake. Comprehensive Water Quality Identification Index Method (CWQII) can better assess the water quality compared with the other methods by providing qualitative and quantitative analysis. The index values assessed by CWQII method for Nanfei River, Shiwuli River, and Paihe River were 5.819, 5.986, and 5.141, respectively, and water quality were all assessed as grade V. Overall, water quality of Chaohu Lake has been slightly improved during 2015~2017, but water quality of western inflowing rivers was still heavily polluted. These findings provide valuable information and guidance for water pollution control and water resource management in Chaohu Lake basin. Several feasible measures are proposed.
