Plastics are the most commonly found component of marine debris [2][3][4][5] due to its wide range of applications and its long-term persistence in the environment. Moreover, microplastics can act as carriers of contaminants such as chemical additives or organic contaminants.…”

The beach sediment samples from Kalim, Tri Trang, and Patong Beaches, Phuket Province, southern of Thailand were collected for preliminary investigation on coastal debris. A total of 9 samples were taken from a 1 x 1 m quadrat at the depth of 5 cm, parallel with the shore during the period of maximum low tides in November, 2018. Microplastics (particles size < 5 mm) were extracted using sodium chloride (1.15 g mL-1) and their characteristics- including abundance (items m-2), weight (g), density (itemsm-2), color and shape- were determined using a stereo microscope. The results showed that microplastic debris varied in abundance from 1 to 35 items m-2 at the three selected beaches, depending on sampling location. In comparison, abundance of macroplastic (> 2.5 cm) and mesoplastic debris (5 mm to 2.5 cm) varied from 1 item m-2 quadrat (Kalim Beach) to 38 items (Patong Beach), 9 items (Tri Trang Beach) and 68 items (Patong Beach) m-2. Blue fibers were predominant among microplastic debris found at Kalim Beach; these are likely to have originated from pieces of rope, safeguard lines and fishing materials. In contrast, microplastic debris found in Patong and Tri Trang Beaches were predominantly green in color. The results of this study provide an overview of the sources of microplastics in coastal environments, which provides a basis for developing long term plastic management plans for these highly popular beaches in Phuket Province.

“…This setting shows that the bay acts as a sink, especially for fine sediment particles. Nowadays, considering the alarming environmental quality of Guanabara Bay Fonseca et al, 2013;Abuchacra et al, 2015;Cordeiro et al, 2015;Fistarol et al, 2015;Abreu et al, 2016;Aguiar et al, 2016;Carvalho and Baptista Neto, 2016;Silva et al, 2016;Soares-Gomes et al, 2016), we assume that the bay acts as a sink not only for sediments but also for pollutants.…”

Northeast Guanabara Bay and Coastal Plain Holocene Sedimentary Evolution (Brazil): A Contribution

et al. 2017

Sedimentological and radiocarbon investigations are part of an ongoing research on the Bay-head delta of northeast Guanabara Bay, Rio de Janeiro State. Sediment accumulation indicates that the Holocene infill of the bay-head delta started around 8.2 kyr BP and was not in pace with the eustatic sea-level rise. Sediment accumulation was faster during the transgressive phase (0.56 cm.yr -1 ). However, during the regressive phase, progradation driven by baselevel fall was predominant over vertical sediment accumulation (0.02 cm.yr -1 ). Based on coring, three sedimentary units were defined: fluvial sands (U1), estuarine deposits (U2) and fluvial mud (U3).

Since the beginning of mass production of plastic in the mid-20th century, environmental contamination by this anthropogenic material has been growing and is becoming increasingly apparent, and is even considered a potential geological indicator in the Anthropocene. Microplastics is a term used to group a range of different polymeric synthetic materials of size < 5 mm. These materials have been reported by several studies in different environmental matrices globally and present physical and chemical risk to organisms at the base of the food chain. However, in Brazil, interest in the subject is relatively new and few studies have been published in recent years. Here we present an overview of the plastic industry, microplastics as contaminants in the Anthropocene and review the literature on microplastic contamination in Brazilian environmental matrices with their respective methodologies.
