Arraial do Cabo, RJ, Brazil, is known as the diving capital due to its clear waters and great biodiversity, a consequence of the upwelling phenomenon. This feature attracts tourists tripling their population during holidays, causing increase in the amount of debris on beaches and waters endangering marine biodiversity. To evaluate the amount of solid waste found on beaches in two different holiday period, eight people in each beach collected macrodebris (≥2 cm) in a transect covering an 20 m wide area, during 20 min, in winter/2015 and summer/2017. The materials were weighed, quantified and characterized. In the summer, when the number of tourists is greater, a larger total amount of waste in units were found. Plastic and cigarette butts were the most abundant. The results show that the city does not have adequate planning to receive a large amount of tourists, being vulnerable to socioeconomic and environmental damages.
巴西里约热内卢州的阿雷格里港被称为潜水之都，因为它的海水清澈，生物多样性丰富，这是上升流现象的结果。这一特征吸引了游客，使他们的人口在假期期间增加了两倍，导致海滩和水域上的碎片数量增加，危及海洋生物多样性。为了评估在两个不同假期期间海滩上发现的固体废物的数量，在 2015 年冬季和 2017 年夏季，每个海滩的 8 人在一个 20 米宽的横截面上收集了大于 2 厘米的大碎片（macrodebris），持续 20 分钟。对材料进行称重、量化和特征描述。在游客较多的夏季，发现的废物总量更大。塑料和烟头是最丰富的。结果表明，该市没有足够的规划来接待大量游客，容易受到社会经济和环境破坏的影响。
