Shandong Province is among China’s major marine provinces, and the marine environment in Shandong supports important economic activities, such as fishing, aquaculture, and tourism. The presence of microplastics in the marine environment can impact these activities and the livelihoods of people who depend on them. Therefore, studying microplastics in Shandong Peninsula is crucial for understanding and mitigating these impacts. In this research, the microplastics were detected with abundance ranging from 50.67 to 315.2 particles/kg dry weight, and polyethylene and polypropylene have dominant proportions in beach sand and sediments. Microplastics were also detected in holothurians and oysters with detection rates at 16.7% and 38.9%, respectively. This study highlighted that microplastics pollution in the Shandong Peninsula was closely related to anthropogenic activities. Moreover, microplastics have inhibited superoxide dismutase activity and significantly increased malondialdehyde during zebrafish growth, which provided a potential effect between microplastics and marine organism. Human activities contribute to microplastics pollution in the environment, while at the same time, the presence of microplastics can impact marine organism and human activities. To mitigate the impacts of microplastics on the Shandong Peninsula, it is important to reduce the sources of microplastics and to develop effective management strategies for controlling their spread and impact.

“…So, even though research on the presence of MP in the environment has increased exponentially in recent years, there are no standardized methodologies for MP sampling in the field and for the analysis of samples in the laboratory (Tirkey and Upadhyay 2021). It is common for researchers to rely on methods that have been proposed by different working groups (Masura et al 2015, Viršek et al 2016, Besley et al 2017, Lin et al 2021, which often adapt based on the needs of their approaches (Bridson et al 2020, Chen and Chen 2020, Godoy et al 2020, Maynard et al 2021.…”

Marine environments are the most studied habitats when addressing microplastic pollution. However, there are no standardized methodologies for this analysis, so methodologies are often adapted by researchers. This situation has raised doubts concerning the reliability and reproducibility of results that are related to the null or little use of measures to avoid cross-contamination. The objective of this work was to carry out a short review and analyze the different measures that have been reported in research articles for different marine habitats, published in the ScienceDirect database in 2020, to avoid cross-contamination during fieldwork and laboratory work. From the 115 analyzed articles, eight did not report measures at any stage, 61 took measures during sampling, and 98 did it in the processing stage. Even though most studies take steps to prevent cross-contamination, they do not specify the percentage of contamination avoided. However, from the concentrations of microplastics in the blanks and the total microplastic concentrations in the samples, we estimate that between 4.8 and 69 % of contamination is avoided in sampling and between 0.1 and 48.8 % in the laboratory. This shows the need to establish standards for sampling and sample processing, which must include measures regarding the marine environment studied and the stage addressed, as well as the minimum percentages that should be met for the data to be considered valid and reliable.

“…The presence of marine residues, mostly resulting from anthropic activities, is responsible for the degradation of the coastal and marine ecosystem (Barbosa et al, 2018;Garcés-Ordóñez et al, 2020). This issue has led to serious environmental and socioeconomic problems, ranging from water contamination (Maynard et al, 2021), death of marine animals by ingestion or entanglement (Roman et al, 2020), expenditures on cleanup and the loss of tourism potential (Krelling et al, 2017). Studies have revealed that plastic is the most expressive item in coastal areas in Brazil (Araújo, 2003;Magalhães & Araújo, 2012;Sassaki et al, 2016;Santos, 2017;Nobre et al, 2018;Andrades et al, 2020;Gonçalves, 2020;Ribeiro et al, 2021).…”

The irregular waste disposal is a reality that affects the Brazilian coast. The present study aimed to evaluate the environmental perception of beach users in relation to the production and disposal of solid waste at Tamandaré beach - Brazil. It was applied a questionnaire and carried out a quali-quantitative collection that has shown that the impacts mostly pointed out were the damage to the environment, and loss of tourist potential. The main source of dispersion of waste on the Tamandaré shore is associated with land-based activities, mainly those arising from tourism. The main causes were the failure in the municipal cleaning system, and beach users lack of awareness on disposing solid waste. It was suggest implementing environmental education programs, infrastructure improvement, and the elaboration of public policies pertinent to the management of solid waste, with the purposes of protection and conservation of natural resources.
