Coastal areas globally face mounting challenges due to increased human activities, resulting in substantial environmental impacts on beaches and marine ecosystems. This study delves into the influence of peak tourist seasons on cigarette butts (CBs) contamination along an urban beach, specifically Mar Grosso beach boardwalk in Laguna, Brazil. The study period spanned peak tourist seasons (PS) and off-seasons (OS), with data collected on CBs density and degradation levels across different areas of the boardwalk. A total of 6621 CBs were collected from the beach boardwalk along Mar Grosso beach, resulting in a density of 0.50 CBs/m. It is worth noting that higher CBs densities were observed during the PS (0.38 CBs/m), particularly in areas with urban structures that attract human presence, despite the presence of waste collection bins. Stages II and III of CBs degradation were the most abundant along the Mar Grosso beach boardwalk. Moreover, our research indicates a severe pollution index for the Mar Grosso Beach boardwalk during the PS season in all analyzed sectors (18.25-31.60). The study underscores the urgent need for improved waste management practices, environmental education, and policy interventions to curb CBs contamination and its adverse impacts on coastal ecosystems and public health.
全球沿海地区因人类活动增加而面临越来越多的挑战，对海滩和海洋生态系统造成了重大环境影响。本研究深入探讨了旅游旺季对城市海滩（特别是巴西拉古纳的马格罗索海滩木板路）烟头污染的影响。研究期涵盖旅游旺季（PS）和淡季（OS），收集了木板路不同区域烟头密度和降解水平的数据。从马格罗索海滩的木板路上共收集到6621个烟头，密度为0.50个烟头/米。值得注意的是，在旅游旺季（0.38个烟头/米）观察到更高的烟头密度，特别是在有人聚集的城市结构区域，尽管设有垃圾桶。在马格罗索海滩木板路上，烟头降解的第二和第三阶段最为常见。此外，我们的研究表明，在旅游旺季，马格罗索海滩木板路所有分析区域的污染指数都很严重（18.25 - 31.60）。该研究强调迫切需要改进废物管理做法、开展环境教育并进行政策干预，以遏制烟头污染及其对沿海生态系统和公众健康的不利影响。
