Total and partial restrictions to beach access during COVID-19 pandemic created an opportunity to evaluate its effect on coastal pollution. We aimed to determine the impact of access restrictions on solid waste pollution at Copacabana beach, Brazil. Solid waste amount was analyzed considering beach access restrictions: unrestricted, total closure, partial restriction, new normal. Relationships of atmospheric temperature and precipitation with access restrictions were assessed and confounding effects controlled for further analyses. Beach access restrictions significantly reduced solid waste pollution at Copacabana beach, beach closure reduced waste amount in 72 %. Partial restrictions and new normal periods have significantly reduced solid wastes amount on the beach in 60 % and 36.88 %, respectively. Qualitative data revealed that most of solid wastes were single-use plastics recently disposed at Copacabana beach, reflecting beachgoer's effects on waste left on the beach. A positive impact of COVID-19 pandemic restrictions was detected on solid waste pollution at Copacabana beach.
在 COVID-19 大流行期间，海滩的全面和部分限制为评估其对沿海污染的影响提供了机会。我们旨在确定限制进入对巴西科帕卡巴纳海滩固体废物污染的影响。考虑到海滩的进入限制，分析了固体废弃物的数量：不受限制、全面关闭、部分限制、新常态。评估了大气温度和降水与进入限制的关系，并为进一步分析控制了混杂效应。海滩进入限制显著减少了科帕卡巴纳海滩的固体废物污染，海滩关闭减少了 72%的废物量。部分限制和新常态期间，海滩上的固体废物量分别减少了 60%和 36.88%。定性数据显示，最近在科帕卡巴纳海滩上处理的大部分固体废物都是一次性塑料，反映了海滩游客对留在海滩上的垃圾的影响。在科帕卡巴纳海滩，COVID-19 大流行限制对固体废物污染产生了积极影响。
