Climate change and marine litter are inextricably linked, their interaction manifests differently depending on the specific environmental biological characteristics, other human activities taking place. The negative impacts resulting from those synergistic interactions threatening coastal ecosystems many goods services they provide. This is particularly pervasive in zone of Indian subcontinent. India already experiencing severe climate impacts, which projected to worsen future. At same time, country gripped by a crisis that overwhelming authorities communities hindering country's sustainable development goals. environment southern states Kerala Tamil Nadu vulnerable change. While these state governments stepping up efforts improve management zones, scale severity issues mounting. Here we review combined effects pollution Southern India, focusing Gulf Mannar Reserve Malabar Coast Kerala. Finally, discuss effective options could help resilience sustainability.

Characterization and removal efficiencies of microplastics discharged from sewage treatment plants in Southeast Spain

Water Research, Journal Year: 2023, Volume and Issue: 244, P. 120479 - 120479

Published: Aug. 17, 2023

Microplastics (MPs) are ubiquitous pollutants that can effectively harm different ecosystems. The information on the relative contribution of wastewater treatment plants (WWTPs) to surrounding environment is important, in order understand ecological health risks and implement measures reduce their presence. This focus article presents a quantitative assessment concentration types MPs delivered from four WWTPs located at Southeast Spain. Samples were collected throughout four-year period, comprising more than 1,200 L analyzed 3,215 microparticles isolated. Density extraction with 1.08 g/mL NaCl salt solution was systematically used as main separation method, simple reliable manner, repeat cycles did not play any significant impact study outcomes. had removal efficiencies between 64.3% 89.2% after primary, secondary, tertiary phases, without diurnal or daily variations. Advanced methods displayed lower rate for fibers particulate MPs. abundance always higher mean size samples Autumn rest seasons. dumped large quantities into meant be regarded an important point source aquatic terrestrial environments.

Fire and Oil Led to Complex Mixtures of PAHs on Burnt and Unburnt Plastic during the M/V X-Press Pearl Disaster

ACS Environmental Au, Journal Year: 2023, Volume and Issue: 3(5), P. 319 - 335

Published: July 12, 2023

In May 2021, the M/V X-Press Pearl container ship burned for 2 weeks, leading to largest maritime spill of resin pellets (nurdles). The disaster was exacerbated by leakage other cargo and ship's underway fuel. This affords unique opportunity study a time-stamped, geolocated release plastic under real-world conditions. Field samples collected from beaches in Sri Lanka nearest comprised nurdles exposed heat combustion, burnt pieces (pyroplastic), oil-plastic agglomerates (petroplastic). An unresolved question is whether 1600+ tons spilled recovered should be considered hazardous waste. Due known formation toxicity combustion-derived polycyclic aromatic hydrocarbons (PAHs), we measured 20 parent 21 alkylated PAHs associated with several types plastic. maximum PAH content sampled pyroplastic had greatest amount recorded marine debris (199,000 ng/g). contrast, unburnt white two orders magnitude less content. composition varied between presented features typical conflicting petrogenic pyrogenic sources. Nevertheless, specific markers compositional changes burning plastics were identified, revealing that fire main source PAHs. Eight months after spill, contents stray reduced more than 50%. their exceeding levels allowable consumer goods, classifying as waste may warranted. Following largely successful cleanup, recommend Lankans re-evaluate identification, handling, disposal potential exposure responders public handling it. underscores type pollution has yet fully explored, despite pervasiveness intentional unintentional globally.

Anthropogenic nitrogen pollution threats and challenges to the health of South Asian coral reefs

Frontiers in Marine Science, Journal Year: 2023, Volume and Issue: 10

Nitrogen pollution is a widespread and growing problem in the coastal waters of South Asia yet ecological impacts on region’s coral ecosystems are currently poorly known understood. hosts just under 7% global reef coverage but has experienced significant loss recent decades. The extent to which this ecosystem decline at regional scale can be attributed multiple threats posed by nitrogen been largely overlooked literature. Here, we assess evidence for corals central Indian Ocean India, Sri Lanka Maldives. We find that there limited with clearly demonstrate reefs from pollution, including its interactions other stressors such as seawater warming. However, does not prove no impacts, rather it reflects paucity appropriate observations related understanding range potential individual, species levels. This situation presents research, management conservation challenges given wide acceptance problematic. Following this, recommend more systematic collection sharing robust observations, modelling experimentation provide baseline base prescient control action.
