RESUMO
A contaminação por resíduos sólidos no ambiente marinho é uma questão
que deve ser tratada com cuidado, uma vez que a sua importância é
crescente desde a substituição de materiais degradáveis por outros não
degradáveis. A Reserva Biológica Marinha do Arvoredo (RBMA) enquadra-se
na mais restritiva categoria das unidades de conservação integral.
Apesar disso, a contaminação por resíduos sólidos tem sido evidente.
Sendo assim, o presente trabalho teve como objetivo quantificar e
qualificar os resíduos sólidos encontrados na ilha do Arvoredo
(27°17’S; 048°22’W), principal ilha da RBMA. Foram realizadas cinco
coletas no período de fevereiro de 2004 a janeiro de 2005, utilizando
dois métodos de amostragem: a) coletas junto ao fundo através de
técnicas de busca e recuperação utilizando mergulho autônomo e, b)
manualmente na costa adjacente (coletando a totalidade de resíduos
sólidos, exceto madeira, nas áreas amostradas). A metodologia de fundo
foi utilizada em 15 amostragens ao longo das 5 saídas no Saco do Farol
e no Saco do Vidal (fora da RBMA) e se mostrou viável para
transparências acima de 1m e profundidades até 15m. Já as amostragens
na costa da ilha foram realizadas em duas áreas distintas, no Saco das
Balas (dentro da RBMA), e nos Sacos do Farol e Vidal (fora dos limites
da RBMA). Os resultados demonstraram que há uma elevada contaminação
por resíduos sólidos na ilha do Arvoredo, tanto na costa quanto no
fundo marinho. Os principais tipos de resíduos encontrados no fundo
foram cabos, âncoras, pneus e linhas de pesca, enquanto que na costa
foram isopores (que são utilizados como flutuadores de redes e em
caixas térmicas para alimento e pescado) e garrafas e recipientes
plásticos (utilizados para o transporte de bebidas e de óleo
lubrificante e combustíveis). Os resíduos encontrados no presente
estudo tiveram uma origem predominantemente marinha, oriunda
provavelmente de embarcações de turismo e/ou pesqueiras que realizam
suas atividades ao redor da Reserva.

ABSTRACT
Marine environment contamination by debris is an issue that must be
treated carefully, since its importance grows due to the substitution
of biodegradable for non-degradable materials. The Arvoredo Marine
Biological Reserve (RBMA) is categorized as the most restrict
conservation unit, according to Brazilian National Conservation Unit
System (SNUC). Visitation in this kind of units is allowed for
environmental education and scientific purpose only. Despite of that,
the marine debris contamination is evident. Thus, this work identified
and quantified all the debris found at Arvoredo Island (27°17’S;
048°22’W), the main island of RBMA. Samples were taken during 5
fieldworks (February 2004 (summer), May 2004 (autumn), July 2004
(winter), October 2004 (spring) and January 2005 (summer)) using two
different sampling methods: a) bottom sampling by scuba diving using
search and recovery technique and, b) manual sampling at the adjacent
coastal shore (collected all debris in the sampling area except wood
debris). The bottom sampling was used in 15 samples at Farol Bay and
Vidal Bay (both outside from RBMA). The applied technique showed to be
viable for waters with at least 1m of transparence and up to 15 meters.
The coastal shore of the island was sampled in the Bala Bay (within the
RBMA), and the Farol Bay and Vidal Bay (outside the boundaries of
RBMA). Compared to others studies around the world, Arvoredo island
showed high levels of contamination at sea bottom (an average of 14.4
items/1.000m²) and coastal shore (an average of 3.33 items/m). During
the sampling period, the coastal shore located inside the RBMA was
always more contaminated than the one located outside the conservation
unit. Cable, anchor, tire and fishing line were the most common
materials found at the bottom, while styrofoam (used in floating net
artifacts and coolers for food and fish), bottles and other plastic
recipients (used to carry juices, soft drinks, spirits, homemade chili,
engine lubricating oil and fuel) were at coastal shore. Some of the
recipients were even found full of lubricant oil and fuel. The residues
found in this study had a predominantly marine origin, probably
deriving from touristic boats and/or carrying out fishing activities
around the conservation unit area. At least the presence of fishermen
in the area is evident, since they use these kind of materials for
daily on board activities.
