A set of 45 samples of the sludge from wastewater factories in the area of the Czech Republic was completed. The selection of wastewater factories reflected the extent of observed area as well as the occurrence of the industrial wastewater. The contents of persistent organic pollutants (POPs) were determined in the samples. Moreover, the contents of polychlorinated dibenzo-p-dioxins and dibenzofuranes (PCDD/F) were detected in 16 samples. The set of analytical data summarises the level of sewage sludge contamination by POPs within Czech wastewater factories. The results were compared with the directive of Czech Ministry of Environment, No. 382/2001 Sb. and with the proposed limit values of the EU directive, No. 86/278. Among all the determined substances only the value of the sum of polycyclic aromatic hydrocarbons (PAHs) content exceeded the threshold value given by the proposed EU directive.

The recommended maximum contents of the substances from the group of persistent organic pollutants (POPs) in sludge for the application on agricultural soils were proposed. The list of the substances follows Czech legislative norms for soil protection (Directive of the Ministry of Environment No. 13/1994 Sb.). The list includes the groups of polycyclic aromatic hydrocarbons (PAHs), monocyclic aromatic hydrocarbons (MAHs), the amount of six congeners of polychlorinated biphenyls (PCB<sub>6</sub>), DDT and residues, polychlorinated dibenzo-p-dioxins and dibenzofuranes (PCDDs/Fs). Recommended maximum contents were proposed on the basis of the determination of background values of POPs in the set of 45 sludge samples from the wastewater factories in the territory of the Czech Republic. The results of vegetation experiments focused on the POPs in soil and plants after sludge application were used and the proposal of EU legislation Working Document on Sludge was investigated.

Seawater Samples

Solid phase extraction (SPE) is a consolidated technique for determining pollutants in seawater samples. The current tendency is to miniaturise systems that extract and determine pollutants in the environment, reducing the use of organic solvents, while maintaining the quality in the extraction and preconcentration. On the other hand, there is a need to develop new extraction systems that can be fitted to in situ continual monitoring buoys, especially for the marine environment. This work has developed a first model of a low-pressure micro-SPE (m-SPE) for persistent organic pollutants (POPs) that can be simply applied to in situ monitoring in the marine environment. This system reduces the volumes of sample and solvents required in the laboratory in comparison with conventional SPE. In the future, it could be used in automated or robotic systems in marine technologies such as marine gliders and oceanographic buoys. This system has been optimised and validated to determine polycyclic aromatic hydrocarbons (PAH) in seawater samples, but it could also be applied to other kinds of persistent organic pollutants (POPs) and emerging pollutants.

Sediments were sampled from different surface water bodies in Tianjin coastal area, China, and persistent organic pollutants (POPs) including polycyclic aromatic hydrocarbons (PAHs), organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), and polybrominated diphenyl ethers (PBDEs) were measured using GC/MS or GC/ECD. The purposes were to investigate the concentration levels of the POPs and to assess their ecological risks. The results showed that all the 16 priority PAHs were detected from the 10 sediments sampled with the total concentrations of the 16 PAHs ranging from 274.06 μg/kg to 2656.65 μg/kg, while the concentrations of the halogenated POPs were generally low except in the Dagu waste discharging river where the total concentrations of 24 OCPs, 35 PCBs, and 14 PBDEs were 3103.36 μg/kg, 87.31 μg/kg, and 13.88 μg/kg, respectively. In the studied sediments, PAHs exhibited risks to benthonic organisms; particularly the concentrations of naphthalene and/or acenaphthene exceeded their probable effect concentrations in several locations. In comparison, only in the Dagu waste discharging river, OCPs exhibited risks with the concentrations of heptachlor epoxide and lindane exceeding their probable effect concentrations. PCBs and PBDEs posed rare risks in the studied area.

Abstract The EU Directive 5 June 2019, n. 904, aims to promote sustainable reusable products and systems in a circular perspective, reducing the production of disposable products and waste. Abandoned plastics take decades to disintegrate, never disappearing completely from the environment, with serious consequences for human health. A study conducted by the European Food Safety Authority (EFSA) has found that pollutants such as polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs) or bisphenol A (BPA) can accumulate in microplastics, which are swallowed by humans as well as inhaled or ingested reaching lungs. For instance, it has been estimated that every week we ingest the same amount of microplastics as a credit card. Furthermore, plastic kills and damages biodiversity. Aquatic animals are the most affected, as they are either trapped in man-made plastic waste or they swallow plastics with serious damage to their and the humans' health that eat them. Dangerous are also nanoplastics that can penetrate cell walls and are chemically more reactive. However, Directive 2019/904/EU does not eliminate the use of plastic, setting the percentages of recycled plastics to be used in the manufacture of disposable plastic products. For instance, beverage PET bottles must contain at least 25% of recycled plastic from 2025 and 30% from 2030. Despite the Directive has provided elements for states to legislate in favour of a society that makes less use of plastics, today no zero- plastic society has been created. In order to achieve this 'zero' it is necessary to start from the citizens, raising their awareness through awareness-raising campaigns and the distribution of leaflets and posters on the consequences of the mismanagement of plastic waste (and microplastics) on their health and on the environment. Key messages Raise citizens awareness on the consequences of the mismanagement of plastic waste (and microplastics) on their health and on the environment is fundamental. The importance of the creation of a zero plastic society thanks to the application of Directive 2019/904/EU at international level.
