Highlights Protected areas were studied as spaces for adaptation to COVID-19. The socio-psychological model of precautionary adaptation was employed. High perceived adaptation efficacy and low adaptation cost promoted adaptation. The ability of protected areas to assist in adaptation to pandemics was highlighted.

Increasing visits to protected areas in China have drawn public attention on the negative impacts on ecologically sensitive areas. Understanding potential determinants of the environmentally responsible behavioral intention of nature-based tourists has become a common focus in tourism studies. Scholars seek to explore potential determinants of visitors’ behavior, and the findings can be referenced by the managers of protected areas to formulate visitor management strategies. On the basis of a sample of 402 questionnaires collected in protected areas in South China, namely, Nanling National Forest Park and Dinghu Mountain National Nature Reserve, we explore the association between visitors’ place attachment and their satisfaction and environmentally responsible behavioral intention. The results show that place dependence and place identity are positively correlated with the satisfaction and environmentally responsible behavioral intention of visitors; thus, our results differ from those of previous studies on Western visitors. The lack of significant results regarding place social bonding revealed the shortcomings associated with visitor management in China’s protected areas. Chinese culture has a great influence on various findings in this study. All of the findings provide significant insights for management and policy-making regarding protected areas worldwide to accommodate the rising number of nature-based visitors to China.

Microplastics have been documented in a wide range of commercially available food products, and the presence of microplastics in tap water has received considerable attention in recent years. Although microplastics in drinking water pose a low concern for human health at current levels of exposure, there is a need to understand the potential pathways for human microplastic exposure. With the application of Rose Bengal staining, microplastics in 110 surface water-sourced tap water samples from urban sources in Hong Kong were qualified and morphologically characterized. A total of 224 items were identified in 86 (78.2%) samples with a mean concentration of 2.181 ± 0.165 n L−1. Fibrous and smaller (<1 mm) microplastics predominated in samples, accounting for 97.8% and 65.1% of the total microplastic count, respectively. Our results indicated a comparatively low level of microplastic contamination of tap water in Hong Kong. The potential sources of microplastics could be microplastic-polluted water bodies, atmospheric input and mechanical abrasion of plastic equipment during water treatment and distribution.
