“…However, tourism growth has led to direct and indirect impacts on the coastal ecology and environment (Gladstone et al, 2013 ; Williamson et al, 2017 ; Zupan et al, 2018 ), thus affecting the benefits of ecosystem services (De Valck & Rolfe, 2018 ). Tourism, including the existing activities and intensive development, remarkably gives a negative contribution to environmental pollution (Le Grand et al, 2017 ; Liberatore et al, 2015 ; Moschino et al, 2017 ; Suciu et al, 2017 ), including marine debris (Wilson & Verlis, 2017 ; Hayati et al, 2015 ) and microbial bacteria (Torres-Bejarano et al, 2016 ). Also, tourism development leads to a rapid change in the landscape due to the increasing human population as a consequence of the growing number of visitors and urbanization (Bottema & Bush, 2012 ; D'Angelo & Wiedenmann, 2013 ; Hampton & Jeyacheya, 2014 ; Kurniawan et al, 2016a , 2016b ; Ngah et al, 2012 ); consequently, the landscape of the island becomes more exposed and later contributes to the decline in seawater quality.…”

The contribution of seawater quality degradation was caused by terrestrial runoff of waste materials from household and tourism industries on the land or as land-based nutrient enrichment and pollution (Edinger et al, 2000 ; Lapointe et al, 2004 ; Le Grand et al, 2017 ). Fabricius ( 2005 ) and Beher et al ( 2016 ) stated that the runoff from the mainland is one of the most significant threats to the marine and coastal environments.…”

Tourism is one of the most important issues facing marine protected areas (MPAs) and small islands worldwide. Tourism development is considered a contribution to pollution levels in the environment. This paper aims to evaluate the hypothetical effects of tourism development on water quality spatially and temporally using the coastal water quality index (CWQI) and Geographic Information System (GIS) in search of improved management for marine conservation areas. This study showed significant tourism influences on the CWQI in the Marine Tourism Park of the Gili Matra Islands, Lombok, Indonesia. Water quality variability indicates a significant spatiotemporal difference ( p < 0.05) in the two tourism seasons. During the peak season of tourism, the CWQI decreased to poor conditions, i.e., ranging from 9.95 to 21.49 for marine biota and from 7.98 to 30.42 for marine tourism activities in 2013, and ranging from 39.52 to 44.42 for marine biota and from 44.13 to 47.28 for marine tourism activities, which were below the standard for both marine biota and marine tourism activities. On the contrary, it showed a better level (from poor to moderate) during the low season of tourism (ranging from 41.92 to 61.84 for marine biota and from 48.06 to 65.27 for marine tourism activities in 2014), providing a more acceptable condition for both aspects. The study proved that massive tourism development in the MPA and small islands could reduce water quality and increase vulnerability. Accordingly, integrated tourism management and the environment, waters, and land will be needed to develop sustainable tourism. The CWQI and GIS were applicable to assess water quality, both spatially and temporally, and become a quick reference in monitoring and initial evaluation of impact management.

Field determination and ecological risk assessment of dissolved lead (Pb) were performed at two Yellow Sea sites in China using a continuous automated electrochemical system (CAEDS). This CAEDS instrument includes an automatic triple filter sampler and an electrochemical detection water quality analyzer, which might be operated automatically four times daily. The dissolved Pb concentrations varied from 0.29 to 1.57 μg/L in the South Yellow Sea over 16 days and from 0.32 to 2.28 μg/L in the North Yellow Sea over 13 days. During the typhoon and algal bloom periods, the Pb concentration was as high as ten times greater than usual. According to the calculation of contamination factors (Cf) and subsequent analysis, seawater quality was classified as Grade II. Through species sensitivity distribution (SSD) method experiments and ecological risk analysis, an average risk quotient (RQ) below 1 for both areas was obtained, indicating a low-to-moderate ecological risk. This system will be helpful for Pb monitoring and assessment in seawater and contribute to the biogeochemical cycling study of Pb.
