Polychlorinated biphenyl proﬁle in polyhydroxy-alkanoates synthetized from urban organic wastes

The microbial synthesis of polyhydroxyalkanoates (PHA) from organic wastes is a valuable
process to valorize available renewable resources, such as food wastes and biological sludge.
Bioplastics find many applications in various sectors, from medical field to food industry. However,
persistent organic pollutants could be transferred from wastes to the final product. The present
paper demonstrates that the use of municipal wastes in PHA production is safe for the environment

Air quality assessment in different environmental scenarios by the determination of typical heavy metals and Persistent Organic Pollutants in native lichen Xanthoria parietina

The study was aimed to evaluate the ability of native lichen Xanthoria (X.) parietina to biomonitor and bioaccumulate some heavy metals (As, Cd, Co, Cr, Ni, Pb), PAHs, PCDDs, PCDFs, PCBs and PBDEs and to evaluate the use of the native X. parietina as a multi-tracer tool for scenarios characterized by different anthropogenic pressures. Samples of native X. parietina were collected in six different sites (two green, two residential and two industrial areas, respectively) and analyzed for the target compounds. The results show that X.

Gasification treatment of poplar biomass produced in a contaminated area restored using plant assisted bioremediation

Remediation of polluted soils using phytoremediation techniques is an effective strategy. However, the use of the biomass from these soils for energy purposes may raise efficiency and pollution emission problems and there is currently little research on this issue.In this work, the main results of a fluidized-bed gasification treatment conducted on poplar biomass pruning residues from a multi-contaminated area are presented.
