“…A variety of previous studies have focused on the concentrations and distribution patterns of microplastics in the coral reef environments worldwide, from Africa to the Atlantic and from the South China Sea to South America. ,− However, the influences of microplastics in reef environments on its bioaccumulation by corals were usually neglected. In the present study, the correlation analysis showed that the microplastic concentration in P.…”

Scleractinian corals have been observed to be capable of accumulating microplastics from reef environments; however, the tolerant mechanism is poorly known. Here, we examined the response of Porites pukoensis to microplastic pollution by analyzing algal symbiont density, energetic metabolism, and caspase3 activities (representing the apoptosis level) in the coral–Symbiodiniaceae association. The environments of three fringing reef regions along the south coast of Sanya City, Hainan Province of China, were polluted by microplastics (for example, microplastic concentrations in the seawater ranged from 3.3 to 46.6 particles L–1), resulting in microplastic accumulation in P. pukoensis (0.4–2.4 particles cm–2). The accumulation of microplastics was negatively correlated to algal symbiont density in the corals but not to caspase3 activities in the two symbiotic partners, demonstrating that P. pukoensis could tolerate accumulated microplastics despite the decrease of algal symbiont density. Furthermore, results from the carbon stable isotope and cellular energy allocation assay indicated that P. pukoensis obtained energy availability (mainly as lipid reserves) using the switch between heterotrophy and autotrophy to maintain energy balance and cope with accumulated microplastics. Collectively, P. pukoensis achieved tolerance to microplastic pollution by maintaining energy availability, which was largely attributed to its high heterotrophic plasticity.

“…Surface water 68% of the samples contained MP, total of MP: 67, range: 0-0.24 MP/m 3 .

The latter plays a fundamental role in the distribution of plastics that are floating on the surface water.…”

“…Within the Gulf of California, there are different areas that could present different hydrodynamic characteristics that influence the distribution and accumulation of plastic waste, examples of this are Cabo Pulmo, the Bay of La Paz, and the Guaymas basin. The transport of MP can be favored by the tides and the coastal dynamic process, as is the case of Cabo Pulmo, which is located in an open mouth area between the Gulf of California and the Eastern Pacific Ocean and is also affected by the cyclonic and anticyclonic eddies that form in the summer due to the currents of the Gulf of California that come from the northern region [37,42]. The opposite case is the Bay of La Paz, which is located in a semi-closed area in which the circular current would show a distribution pattern of plastic waste different from that of Cabo Pulmo [37].…”

“…Regarding the Guaymas Basin, since it is in the center of the Gulf of California, there is a dynamic activity of marine currents that propel the materials that are floating [43], especially those coming from anthropogenic activities that takes place in the port of Mazatlán or in nearby ports [37]. Additionally, the distribution of plastic waste through the marine currents of the Gulf of California is also affected by seasonal variation, since in the spring there is the presence of the South Equatorial current and in the fall of the Costa Rica currents [37,44].…”

Microplastics

Microplastics (MP) have been evidenced in marine and coastal areas worldwide, including the Gulf of California in Mexico, where the Vaquita Marina refuge area is located, which in turn borders the protected natural area Alto Golfo de California y Delta del Rio Colorado. This research aimed to determine the concentrations of microplastics in the Vaquita protection zone, analyzing samples of ten transects of surface water and samples in the sand of five beaches on the coast surrounding the Vaquita protection polygon. The total concentrations of MP in the surface water transects were from 0.000 to 0.020 MP/m3 and their most recurrent characteristics were fragments (69.0%), the chemical composition of polyethylene (60.0%), the blue color (39.0%) and a size of 2.1–3.0 mm (31.0%). While for the beaches, these corresponded to averages ranging from 28.2 ± 36.4; 17.6 to 200.7 ± 77.9; 193.7 MP/m2, the most common characteristics of MP from beaches were filaments (33.2%), PE (32.3%), white (28.0%), and a size of 4.1–5.0 mm (32.0%). The results suggest that part of the MP on the beaches and in the Vaquita Marina refuge area could come from urban areas such as the Gulf of California and activities such as fishing. It is recommended to study all the transects of the Vaquita Marina polygon and more beaches surrounding it in different seasons to better understand the status of MP pollution.

“…MPs can enter various ecosystems and cause detrimental effects in both biotic and abiotic forms. Studies have been carried out to understand the impact of MPs on lower organisms like microalgae [8], coral reefs [9], and zooplankton [10]. Apart from this, investigations have revealed that honeybees [11], freshwater and marine organisms [12,13], slugs, soil [14], plants [15], moss [16], and even the human body [17] can become contaminated by MPs due to increasing ubiquitous plastic consumption.…”

The increasing commercial, industrial, and medical applications of plastics cannot be halted during the coming years. Microplastics are a new class of plastic pollutants which have emerged as escalating environmental threats. The persistence, effects, and removal of MPs present in soil, water, and numerous organisms have become an important research field. However, atmospheric microplastics (AMPs), which are subcategorized into deposited and suspended, remain largely unexplored. This review presents the recent developments and challenges involved in fully understanding suspended and deposited AMPs. The evaluation of indoor suspended MP fibers needs to be critically investigated to understand their implications for human health. Furthermore, the transportation of AMPs to isolated locations, such as cryospheric regions, requires immediate attention. The major challenges associated with AMPs, which have hindered advancement in this field, are inconsistency in the available data, limited knowledge, and the lack of standardized methodologies for the sampling and characterization techniques of AMPs.
